  • Alternaria leaf blight (Alternaria spp.) – an emerging foliar fungal
           disease of winter-summer groundnut (Arachis hypogaea) : A review

    • Authors: NARENDRA KUMAR, RAM DUTTA, B C AJAY, T RADHAKRISHNAN
      Pages: 1043– - 1043–
      Abstract: Alternaria leaf blight of groundnut (Arachis hypogaea L.) is an economic important foliar fungal disease of winter (rabi)-summer groundnut. It is not only distributed in India, but also in other groundnut growing countries like Nigeria, Vietnam and Thailand. Its severity increases whenever the crop is facing any biotic and abiotic stresses. This disease significantly affects pod and haulm yield of groundnut causing a reduction in the pod (13–22%), haulm yield (24–63%) and kernel quality. In cultivated groundnut, very limited sources of moderate resistance are available to Alternaria leaf blight. Now efforts are being made to identify better and stable sources of resistance in cultivated groundnut germplasm and interspecific derivatives. Although cultural, biological and chemical control measures have been used for the management of Alternaria leaf blight but these involve high costs and time. Growing Alternaria leaf blight resistant cultivars is the most effective way to protect groundnut crop. However, conventional breeding approaches have been successful for developing moderate resistance groundnut varieties for Alternaria leaf blight. This review has made an attempt to consolidate the research developments in Alternaria leaf blight and resistance breeding in groundnut.

  • Mineral nutrient analysis of three halophytic grasses under sodic and
           saline stress conditions

    • Authors: CHARU LATA, ASHWANI KUMAR, ANITA MANN, SHOBHA SONI, B L MEENA, SULEKHA RANI
      Pages: 1051– - 1051–
      Abstract: Present study was carried out to assess the effects of soil salinity/sodicity on mineral nutrient status of Urochondra setulosa, Leptochloa fusca and Sporobolus marginatus at ICAR- Central Soil Salinity Research Institute, Karnal, Haryana during 2016–19. Treatments of salinity/sodicity (pH ~ 9.5, pH ~ 10, ECe ~ 30 dS/m, ECe ~ 40 dS/m and ECe ~ 50 dS/m) were created in microplots (2.5 m × 1.5 m × 0.5 m) using saline/sodic water. Na+ and Cl– content (% DW) significantly increased with increasing sodicity/salinity stress condition in all three grass halophytes, whereas K+ content decreased. These grass halophytic species showed relatively less reduction in Ca, Mg and Fe contents up to sodic stress of pH ~ 9.5 and salinity level of ECe ~ 40 dS/m. Zn, Cu and Mn content decreased with increasing stress conditions but higher decrease was observed under sodic stress. The Na+/K+ and Na+/Ca2+ ratio was considered as indicators for measuring salt tolerance in plants. Na+/K+ ratio increased with increasing stress condition in all the three grasses but Leptachloa maintained their Na+/K+ near pH 1.0 under sodic stress condition and also maintained their Na+/Ca2+ below 1.0 up to pH ~ 9.5 and ECe ~ 40 dS/m. Higher sodic stress of pH~10.0 caused significant increase in Na+/Ca2+ in Urochondra and Sporobolus, whereas under highest salinity level, Leptachloa showed highest value for Na+/Ca2+. Changes in the accumulation patterns of nutrient in response to salinity is an important aspect and study showed highest positive correlation between Ca - Mg & Zn and negative between Na - Ca and K.

  • Potential area of micro-irrigation and its outreach across Indian states

    • Authors: P KISHORE, S CHAND, S K SRIVASTAVA
      Pages: 1056– - 1056–
      Abstract: Indian agriculture is predominantly dependent on groundwater and consumes nearly 89% of its total groundwater draft. With recurrence of drought and faster depletion of groundwater resources in recent past, micro-irrigation technology has emerged to play crucial role in managing irrigation water demand and sustaining food security. The policy makers, recognising gravity of water scarcity across the Indian states, have focussed water policy pivotal to micro-irrigation. So, present study aims to estimate potential area across Indian states that are suitable for adoption of micro-irrigation. For estimation, sources of irrigation and crop suitability for micro-irrigation primarily under drip and sprinkler irrigation are considered across the states for year 2018–19. Based on different combinations of irrigation sources, estimate shows that country endows an area of 72–78 million ha on which micro-irrigation can be adopted. At country level, micro-irrigation penetration to our estimates ranges from 14.71–15.81% in recent years. Further, location coefficient reveals that concentration of micro-irrigation has improved over the years, however noticeable variation exists across the states. The states with dedicated agencies to improve micro-irrigation adoption like Andhra Pradesh and Gujarat, show higher penetration. However, the state like Punjab that faces water scarcity has low penetration of micro-irrigation. Therefore, there is need to have state-specific schemes to scale up micro-irrigation area for better trade-off between environmental sustainability and food security.

  • Zinc fertigation studies in Nagpur mandarin (Citrus reticulata) grown on
           black clay soil

    • Authors: P S SHIRGURE, A K SRIVASTAVA
      Pages: 1061– - 1061–
      Abstract: A field experiment was conducted for four seasons (2013–17) on 12-year-old bearing Nagpur mandarin (Citrus reticulata Blanco) plants budded on rough lemon rootstock (Citrus jambhiri Lush) at ICAR-Central Citrus Research Institute, Nagpur, Maharashtra. Six zinc-based treatments, viz. S100 as soil application of ZnSO4 (100 g/plant), S200 as soil application of ZnSO4 (200 g/plant), S300 as soil application of ZnSO4 (300 g/plant, F100 as fertigation of ZnSO4 (100 g/plant), F200 as fertigation of ZnSO4 (200 g/plant) and F300 as fertigation of ZnSO4 (300 g/plant) with uniform doses of macronutrients (450 g N + 150 g P2O5 + 150 K2O/tree/year) were evaluated in a randomized block design (RBD) with four replications on a smectite rich alkaline black clay soil. Significantly higher concentration of Zn in index leaves was observed with fertigation treatments than soil application treatments with regard to fruit yield and quality. The fruit yield was observed significantly lower with soil application of ZnSO4 (11.5–13.95 tonnes/ha with S100-S300) than fertigation treatments (15.6–16.4 tonnes/ha with F100-F300). The fruit quality parameters were observed much higher with F200 followed by F300. On the other hand, the lowest acidity (0.82%) and higher TSS to acidity ratio (11.52) were observed with F200. Hence, the treatment F200, split through 4 pulses at 40 days interval from anthesis to the fruit development stage proved highly efficient for quality production of Nagpur mandarin in central India.

  • Field evaluation of tractor-operated seeder for sowing mat type paddy
           nursery

    • Authors: RAJESH U MODI, G S MANES, J S MAHAL, A K DIXIT, ARSHDEEP SINGH, A K MAHAL
      Pages: 1066– - 1066–
      Abstract: Mat-type nursery having uniform growth is a prerequisite for mechanized paddy transplanting. Generally, this type of nursery is sown manually in the open field or in trays. It requires several simultaneous operations and hence is laborious and time-consuming. The performance of tractor-operated mat-type nursery seeder was evaluated at the Research Farm of Punjab Agricultural University, Ludhiana, Punjab during 2019–20 with an objective to obtain the finest speed of operation to get the uniform seed and soil spread. Study was carried out on three different types of soil (sandy loam, loam and silt loam) for three different forward speeds (1.7, 2.2 and 2.7 km/h). Results have shown that the soil type had a non-significant effect on the performance of the machine, whereas forward speed had significant (P<0.05) effect. In overall, with an increase in forward speed of the machine, there was a reduction in uniformity for both seed and soil spread. The best results were obtained at a forward speed of 1.7 km/h with the overall seed spread of 90.93%, overall soil mat thickness 99.70%, fuel consumption 4.36 l/h and effective field capacity 0.092 ha/h. Therefore, the developed tractor-operated seeder can be operated on sandy loam to silt loam soils with a forward speed of 1.7 km/h with 59.5% saving in cost and 62.6% saving in labour for sowing mat type nursery as compared to manual method with MS frames.

  • Development and evaluation of a battery operated ginger (Zingiber
           officinale) washer for small and marginal farmers

      Pages: 1071– - 1071–
      Abstract: Ginger (Zingiber officinale Rosc.) is a commercial crop grown for its aromatic rhizomes which is used both as a spice and medicine. Being a root crop and owing to its physical structure, ginger rhizomes contain heavy soil load which makes washing as an important and prime post-harvest operation. Manual washing of ginger is a laborious and time consuming process. An experiment was conducted at the ICAR-Indian Agricultural Research Institute, New Delhi during 2020 with an objective to develop a continuous rotary drum type battery operated ginger washer and to evaluate its performance.The machine consists of the frame, feeding and discharge chutes, rotary drum with internal flights, pressure pump and nozzle assembly, battery and a drive unit. The developed washer was evaluated at different feed rate and residence time to appraise the washing efficiency, microbial washing efficiency, bruise index and colour of washed ginger. Increase in feed rate significantly reduced the washing and microbial efficiencies but increased mechanical damage. Washing and microbial efficiencies increased with increase in residence time.Significant difference in the colour was found between washed and unwashed ginger.The best set of conditions under which the washer could be operated was 150 kg/h and 25 sec, at which the machine was found to have mechanical washing efficiency of 92.48%, microbial washing efficiency of 93.18% and 4.54% bruise index. Besides eliminating drudgery of washing operation, the developed washer was found to save time, water and operating cost as compared to manual washing.

  • Response of sorghum (Sorghum bicolor) cultivars to nitrogen in
           non-traditional areas of Bihar

    • Authors: RAKESH KUMAR, GOVIND MAKARANA, J S MISHRA, B P BHATT
      Pages: 1076– - 1076–
      Abstract: A field experiment was conducted at the research farm of ICAR-Research Complex for Eastern Region, Patna, Bihar during summer season of 2017 and 2018 to assess the production potential of grain sorghum (Sorghum bicolor L. Moench) cultivars as influenced by nitrogen levels. Treatments consisting 4 nitrogen levels (0, 40, 80 and 120 kg/ha) as main-plot and 09 sorghum cultivars including 5 hybrids (CSH 13, CSH 14, CSH 16, CSH 25 and CSH 30) and 04 varieties (CSV 15, CSV 20, CSV 23 and CSV 27) as sub-plot, were replicated thrice in a split-plot design. Results revealed that increasing levels of nitrogen from 40–120 kg/ha brought significant improvement in yield attributes and yield over control. Application of 120 kg N/ha produced a maximum grain yield (4.82 t/ha) and net returns (`79.5×103 /ha). Amidst cultivars, CSH 30 recorded significantly higher grain yield (4.92 t/ha), net returns (`82.3×103/ha), benefit-cost ratio (3.34) and economic efficiency (`843 ha/day). Hence, sorghum cultivar CSH 30 grown along with 120 kg N/ha was proved significantly better in terms of crop productivity and profitability in summer season, and may be adapted as choice of viable alternative in non-traditional area of eastern India.

      Abstract: The developed IFS model is having different components which comprise of arable crops (1.04 ha), horticulture crops (0.22 ha), fishery (0.10 ha), mushroom (0.02 ha), poultry (10 birds), vermicompost (0.02 ha) and kitchen garden (20 m2). The overall productivity of model was 174.04 tonnes/ha/year in terms of sugarcane equivalent yield (SEY) during the representative years (2013–18). The farmyard manure (FYM) together with vermicompost and other farm-based by-products saved the nutrients by 338.71 kg N, 124.60 kg P, 306.22 kg K and 769.56 kg NPK (kg/year). The entire annual man-days generated were 441, 465, 473, 467 and 470 in various components during 2013–14, 2014–15, 2015–16, 2016–17 and 2017–18, respectively. However, maximum man-days were generated by crop component (209/year) followed by dairy component (152/year) of the IFS model. The gross return/year/ha obtained was `6.12×103/ha and net returns of (`3.74×103/ha) with per day income of `1025 from 1.5 ha of the IFS model under irrigated agro-ecosystem. Inclusion of horticulture components and boundary plantations in the IFS model also tend to reduce GHG emissions.

The research was done in a split-plot design with four irrigation [(No irrigation (I0), One irrigation at CRI stage, crown root initiation stage; (I1), Two irrigation at CRI, Booting (I2), Three irrigation at CRI, Booting, milking (I3)] and three polymer treatments [(No polymers (P0), Gondkatira @5 kg/ha (P1), Pusa Hydrogel @2.5 kg/ha (P2)] in the main and subplot respectively. The wheat seed yield decreased by 11.90% from I3 to I2, 17.12% from I3 to I1, and 33.74% from I3 to I0. The polymer treatment was used to increase the wheat seed yield. The yield was increased by 7.41% and 1.15% by application of hydrogel and gondkatira over no polymer. The minimum water productivity was registered under three irrigations. The application of gondkatira in wheat increased the water productivity by 8.09% while hydrogel 11.56%. Water stress or no irrigation has a lower Fv/Fm (Maximum quantum efficiency of PS II) (0.73) ratio than to no stress or three irrigations (0.75).

      Abstract: Over decades, the total wheat (Triticum aestivum L.) production of the country has been able to meet the domestic consumption and export considerable amount of it. APEDA reports the export of 2.26 lakh MT of wheat for the worth of `424.94 crores/60.55 USD Millions during 2018–19. Further increase in production is only possible through varietal replacement with varieties having higher productivity potential in the existing production area through horizontal spread. Two reputed wheat varieties of ICAR-IARI, viz. HD 2967 and HD 3086 with good nutrient content and resistance as well as tolerance to major fungal diseases were distributed among 572 farmers of two villages of Haryana and western Uttar Pradesh respectively, with predominant rice-wheat cropping cycle to assess their acceptance level over space and time among villagers through assessment trials from winter (rabi) season 2014–15 to 2019–20. In selected, Haryana and Uttar Pradesh villages the relative yield advantage of HD 2967 was 21.7% and 19.9%, respectively and of HD 3086 was 17.5% and 14.3%, respectively over the local check. HD 3086 additionally reported bold grain, less lodging and less quality loss in the situation of repeated rainfall in maturity stage. The popularity and acceptance of the varieties were evident by the horizontal spread for HD 2967 i.e. 468.2 ha (Haryana) and 383.2 ha (Uttar Pradesh) from 6 and 6.4 ha, respectively from the winter (rabi) season of 2014–15 to 2019–20. The study re-affirms the philosophy of Farmer-to-Farmers spread of modern technologies including the HYV seeds.

      Abstract: Bakanae disease is an emerging problem of Basmati rice (Oryza sativa L.) in India and most of the basmati rice varieties are susceptible to this disease. Present study was carried out to evaluate and identify effective fungicide against bakanae disease of rice for which 12 fungicides (single and in combination) were evaluated against the bakanae disease as seedling treatments during the rainy (kharif) season of the year 2019 and 2020. Minimum disease incidence was observed with the fungicides Carbendazim 50% wp (19.47%), and Tebuconazole 50% + Trifloxystrobin 25% w/w 75 wg (25.71%) during the years of evaluation with maximum yield. Area under disease progress curve was minimum (621.58) with the treatment of Tebuconazole 50% + Trifloxystrobin 25% w/w 75 wg followed by Carbendazim 50% wp (671.30). Differences in bakanae disease symptoms were observed in different treatments. Among treatments, elongated tillers as major symptoms were observed in Mancozeb 75% wp, Zineb 68% + Hexaconazole 4% and Azoxystrobin 23% sc treated plants. Whereas, tiller elongation with rotting was prominent in Kitazin 48% ec treated and inoculated control plants. In case of Carbendazim 50% wp, Tebuconazole 8% + Captan 32% sc treatments, detachment of tillers was prominent. Therefore, seedling treatment with fungicides was observed to be effective in reducing bakanae disease incidence with low AUDPC and high yield compared to inoculated control.

      Abstract: Agriculture is the primary sector of Indian economy contributing substantially towards GDP of the country. Qualified and quality human resources contribute significantly towards agricultural sector in the economy. The present study (2021) attempts to analyze the human resource development in terms of enrollment pattern of students in undergraduate (UG) course of agriculture and allied sciences and reflects on evolving strategies for attracting talented students in this sector. Present study shows that there is a close correlation with State Value of Output in agricultural sector and number of students enrolled in higher agricultural and allied studies. Presently, there are 74 agricultural universities (AUs) under the National Agricultural Research Education System and the present study attempts to analyze the student enrollment patterns of under-graduate students in agricultural universities of India for meeting the scientific manpower needs towards achieving targeted agricultural growth. Five years of enrollment data (2015–20) across AUs was considered. Human resource development in terms of enrolment in the higher agricultural education of agricultural universities is quite low when compared to enrolment of students overall in higher education and pattern of enrollment of girls varied in different regions of the country. This study has brought out an important aspect linked to higher agricultural education that the State Value of Output in agriculture has a positive association with enrollment of the students in higher agricultural education from the state in agricultural sector. It is important to assess the future human resource needs for the various sub-sectors of agriculture.

      Pages: 1107– - 1107–
      Abstract: Soilless agriculture is one of the advanced techniques to cultivate plants without soil, with minimal water and nutrients, and helps in vertical growth of agricultural technology. It is an eco-friendly approach widely used for commercial cultivation of quality vegetables. An experiment was conducted at University of Agricultural Sciences, GKVK, Bengaluru, Karnataka during 2017–19 to evaluate the potentiality and suitability of the hydroponics (M2) and aeroponics (M3) methods over conventional method (M1) for hybrid seed production of tomato (Solanum lycopersicum L.). The experiment had 12 treatments comprising 3 methods of production, 2 parental lines (TAG 1F and TAG 2F) and 2 seed treatments (S1: Control and S2: thiram @2g/kg + chlorpyrifos @3g/kg). Hoagland nutrient solution with pH 5.5–6.5 was used for soilless systems. The results revealed that, among the parental lines, TAG 1F performed better under all the methods of hybrid seed production. Seed treatment increased the per cent survival rate to the tune of 3.26%. Aeroponics and hydroponics performed better than conventional method. Aeroponics showed significantly higher plant height (140.94 cm), fruit weight (124.54 g), total biomass (106.44 g) and test weight (0.39 g) while, hydroponics showed significantly higher number of fruit/plant (45.84) and SVI (2821). It is inferred that soilless agriculture could be a promising tool for quality and year-round healthy hybrid tomato seed production under protected cultivation.

      Abstract: The efficient use and management of natural resources are important factors for success in agricultural farming. An experiment was conducted on round the year fodder production at ICAR-Central Arid Zone Research Institute, Jodhpur, Rajasthan during 2017–18 to 2019–20 by harvesting rainwater from the rooftop of buildings and irrigating crops using a solar operated water pump though drips and micro-sprinklers for efficient use of harvested water. In the 3 m inter-row spaces of bajra napier hybrid (BNH) variety CO 4, three legumes Vigna unguiculata (cowpea), Clitoria ternatea (butterfly pea) and Lablab purpureus (sem) received 40 and 60 kg P/ha, grown as intercrops during the rainy (kharif) season and lucerne in succession on residual P during winter (rabi) season. Among three kharif legumes, significantly higher green (11.19 t/ha) and dry (1.60 t/ha) fodder yields were recorded with cowpea that received 60 kg P/ha. An average 243.97 t/ha green and 37.55 t/ha dry fodder yields was recorded from the system in which share of BNH in green and dry fodder yield was 67.57 and 61.81% respectively. BNH gave 164.85 and 23.21 t/ha green and dry fodder from six cuts, kharif legumes contributed 7.43 t/ha in the green fodder and 1.12 t/ha in dry fodder from a single cut and lucerne produced 71.53 t/ha green and 10.32 t/ha dry fodder from the seven cuts in a year. This system has the capacity to meet out the green fodder requirement of 4–5 adult cattle unit (ACU) round the year from the land unit of 0.1 ha.

  • Bioefficacy of insecticides against Thrips palmi in cotton (Gossypium
           hirsutum)

    • Authors: NAVEEN RAO, RAM KARAN GAUR, RISHI KUMAR, SATNAM SINGH, RAJAN KAMBOJ
      Pages: 1119– - 1119–
      Abstract: Various species of arthropod have been recorded as cotton pests at various stages of its growth as defoliators, tissue borers and sap-suckers, causing considerable yield losses. Among these, thrips are one of the most devastating early-season sucking pests limiting cotton (Gossypium hirsutum L.) productivity directly by feeding and transmitting viruses. So far, scanty information is available on the efficacy of insecticide against thrips in cotton. Thus the present study was carried out at Research farm of CCS HAU, Hisar, Haryana during rainy (kharif) season 2019–20 and 2020–21. The efficacy of 14 label-claimed insecticides against Thrips palmi was evaluated under field and laboratory conditions. Under field conditions, profenofos was the most effective insecticide against thrips at three days after spray, while spinetoram recorded the highest thrips reduction after seven days of spray. The following efficacious chemistries against thrips were fipronil and cypermethrin, whereas flonicamid and buprofezin recorded higher thrips population than other treatments. Under laboratory studies, the leaf dip bioassay was conducted to revalidate the field results, and it was found that profenofos, fipronil and spinetoram were highly effective, causing maximum thrips knockdown, whereas lower mortality was recorded in flonicamid. The study provided baseline data on thrips susceptibility to different insecticides, which can be used to develop an effective management strategy by altering different chemistries to avoid selection pressure.

      Abstract: Field experiments were conducted during 2019–21 in Varanasi, Mirzapur and Bhadohi districts of Uttar Pradesh, with a view to study validation and economic viability of IPM technology in eggplant (Solanum melongena L.) in a farmers’ driven approach. The synthesized improved IPM technology comprising seed treatment with Trichoderma viride @5 g/kg seed; seedling root dip in carbendazim 50 wp @1 g/l followed by chlorantraniliprole 18.5 sc @0.5 ml/l solution against seed borne diseases and shoot and fruit borer, respectively, clipping of borer damaged shoots at weekly interval, installation of pheromone traps @25–30 traps/ha for mass trapping of brinjal shoot and fruit borer (BSFB), need based spray (ETL>5%) of chlorantraniliprole 18.5 sc @0.35 ml/l or emamectin benzoate 5 SG @0.4 g/l or fenpropathrin 30 ec @0.33 ml/l against BSFB, installation of yellow sticky traps, application of Azadirachtin 0.03% @5 ml/l and need based spray of thiamethoxam 25 wg @0.4 g/l or fenpropathrin 30 ec @0.33 ml/l against sucking pests like whiteflies and hoppers, collection and destruction of borer and Phomopsis blight infected fruits, Sclerotinia white rot infected twigs and branches and little leaf affected plants periodically, need based application of carbendazim 50 wp @0.5 g/l for management of Phomopsis blight and white rot, were found effective in reducing the incidence of pests and minimizing the yield losses. The adoption of IPM technology also resulted in reducing the number of chemical sprays to 10 from 21–24 in farmers’ practices (FP) fields in a season with higher fruit yields of 51.1 and 45.3 t/ha in IPM, 39.6 and 33.7 t/ha in FP and 25.7 and 20.4 t/ha in untreated control fields with higher incremental benefit cost (B:C) ratio of 4.61:1 and 4.86:1 in IPM than 3.16:1, 3.24:1 in non-IPM and 2.53:1, 2.42:1 in untreated control plots during 2019–20 and 2020–21, respectively.

      Pages: 1129– - 1129–
      Abstract: Grape (Vitis vinifera L.) is one of the major fruit crops of India and the largest grape producing states are Maharashtra followed by Karnataka, Tamil Nadu, Mizoram and Andhra Pradesh. The glaring inefficiencies in the supply chain of grapes along with its perishable nature leads to huge losses. The study identified farm size, knowledge level, experience, training received, timely labour availability and distance from farm to market as significant determinants of the losses. Though a lot of research and extension has been done on the technologies for improved production and loss reduction, the adoption of the recommendations by the farmers has been found to be differential. Thus, we need to isolate the factors which hinder the adoption of such recommendations. The present study (2019–21) identified the major constraints as the high initial investment in infrastructure, lack of market intelligence system, unavailability of skilled labour, unavailability of timely chemicals and equipments and thus, chalks out the future strategy accordingly to minimise the losses.

      Abstract: Present study was carried out in Jammu district of Jammu and Kashmir with 180 randomly selected wheat growers from three different blocks (R.S. Pura, Suchetgarh and Bishnah) with the objective to analyze the productivity status of wheat (Triticum aestivium L.) crop in irrigated sub-tropics during 2020–21. There was large variation in productivity of wheat crop in different wheat growing regions of the state. Results of the study revealed that all the farmers sown their wheat crop by broadcasting method, 36% farmers replaced their wheat seed and same percentage of farmers adopted the practice of seed treatment. All the farmers applied DAP and urea as basal dose at sowing time and herbicide for controlling narrow and broad leaved weeds. Only 45% farmers applied first irrigation at the crown root initiation stage. Second dose of urea was applied by 100% farmers after first irrigation and 60% farmers applied third dose of urea in their wheat crop. Only 18% of sampled farmers sprayed fungicides. Overall average wheat crop productivity of respondent farmers in study area was 2.789 t/ha and R. S. Pura block had significant difference in productivity of wheat crop as compared to Bishnah (P=.039) and Suchetgarh (P=.010) block.

      Abstract: The productivity of wheat (Triticum aestivum L.) generally remains low under organic farming in north-west India. Being a major crop under organic farming in in this region, the genetic variation among the wheat varieties/genotypes needs to be exploited for better nutrient use efficiency and higher productivity. The present experiment was conducted during winter (rabi) season 2018–19 and 2019–20 at research farm of Punjab Agricultural University, Ludhiana, Punjab to evaluate 9 bread wheat varieties, viz. PBW 1 Zn, PBW 175, PBW 660, Unnat PBW 343, Unnat PBW 550, PBW 1 Chapati, C-306, BWL 3498 and BWL 3500 for better profitability under organic farming. The highest grain yield was recorded with wheat variety Unnat PBW 550 which was statistically at par with PBW 1 Chapati, BWL 3498 and Unnat PBW 343 varieties but significantly better than PBW 1 Zn, C 306, BWL 3500, PBW 175 and PBW 660 varieties. The lowest grain yield was recorded with variety PBW 1 Zn. Similar trend was observed for biological yield and yields contributing characters, viz. effective tillers, number of grains/spike and test weight. The net returns and benefit-cost (B:C) ratios were also the maximum with variety Unnat PBW 550 as compared to all other varieties/ genotypes. The study concluded that wheat variety Unnat PBW 550 performed better than all other varieties under organic farming and can be recommended to organic growers of the state.

      Pages: 1143– - 1143–
      Abstract: Eggplant (Solanum melongena L.) is one of the supreme members of the solanaceous group which is widely grown in India. It is considered as the single and economic host of the fungus Diaporthe vexans causing fruit rot, stem canker and blight disease. The present study was carried at the vegetable research farm of ICAR-Indian Agricultural Research Institute, New Delhi during 2019–20 and 2020–21 to screen the eggplant lines (18 cv.) for resistance against this pathogen. The pathogen was isolated from the infected fruits and confirmed by morphological and sequencing information. Artificial inoculation using pin prick method revealed the presence of variability in the lines for disease. The studied lines were categorized based on Per cent disease index (PDI) and the highest PDI value of 80–100% recorded in cultivars Pusa Shyamla, Pusa Kranti, DBL-186, DBL-187, Muktokeshi and DBSR-52 and thus categorized as highly susceptible. The cultivars NDB-25, Kashi Sandesh, Kalo Solia, DBL-175 and Debjhuri Hazari were reported to be susceptible with PDI value of 60%. In the present study, first time we have report a number of highly resistant lines, viz. BR 112, Swarna Mani, BR 40-7 and IC-112992 with 0% PDI as novel source of resistance against P. vexans. These resistant lines have significant importance in large scale cultivation as resistant varieties by farmers. They can also be further utilized as a parent in population development for the identification of gene (s)/ QTL (s) associated with the resistance.

      Abstract: Citrus holds an important place in promoting the horticultural wealth and economy of India. Foot rot caused by Phytophthora spp. is a widespread problem of the citrus nursery. Citrus jambhiri, a widely used rootstock in nursery production, is found susceptible to the Phytophthora spp. Hence, the present study was carried out to evaluate antagonistic activity of Trichoderma spp. isolates against Phytophthora nicotianae var. parasitica causing foot rot in C. jambhiri under lab and net-house conditions. Seven isolates (parent and mutant) of Trichoderma spp. were tested in vitro. Amongst them, T20 mutant (Trichoderma asperellum) exhibited maximum mycoparasitism, volatile activity and non-volatile activity, i.e. 83.70%, 79.26% and 84.81%, respectively. The same T20 mutant (T. Asperellum) also showed maximum glucanase activity, i.e. 1.98 unit/ml. Further, talc-based bio formulations of T. asperellum T20 isolate (parent and mutant) were tested under net-house conditions over a period of two years (2016–2017 and 2017–2018) at the research farm of Punjab Agricultural University, Ludhiana, Punjab. Amongst all the treatments, the application of T20 mutant (T. asperellum) (seed + soil 15 g) had minimum disease incidence (13.33%), maximum disease control (83.30%) and maximum growth promotion i.e. shoot length (37.67 cm) and root length (30.67 cm). Based on our findings, T. asperellum T20 mutant strain used as seed + soil treatment was able to effectively manage the foot rot, in C. jambhiri nursery under net-house conditions and also promoted the plant growth.

      Abstract: Curvularia leaf spot of maize (Zea mays L.) caused by Curvularia lunata var. aeria is one of serious foliar diseases of maize. An experimental conducted during 2016–17 at research farm of Maharana Pratap University of Agriculture and Technology, Udaipur, Rajasthan found that Curvularia showed considerable variation in growth characteristics, colony diameter and rate of sporulation. The maximum colony diameter was 90.0 mm with 11.0 × 104 conidia/mm2. The size measurement of conidia of C. lunata-01 was in range of 60.1–91.9 μm length and width range was 16.2–23.5 μm. Length and width of isolate C. lunata-02 recorded in range of 55.6–79.5 and 14.2–22.5 μm respectively. Host range distribution showed that pathogen has a wide host range in many crops and weeds under artificial inoculation. Seed transmission results showed that Local surya exhibited higher 66.66% seeds borne inoculam while Pratap makka-3 have 40.00% seed borne inoculums of pathogen. Physiopathological studies shows that 25±2°C was optimum temperature for both the isolates. Maximum mycelial growth and sporulation was found at 90% RH followed by 80% in both the isolates. The 22.29% losses in yield due to Curvularia leaf spot was assessed by using Le Clerg model. The present study of pathogen biology could be used by plant pathologists to develop or redesign management strategies for the maize growers.

      Abstract: Information on genetic diversity with respect to various agro-morphological traits and eating and cooking quality traits plays a key role in the improvement of rice (Oryza sativa L.). With this aim, we have characterized a set of 98 indigenous aromatic rice germplasm accessions for four agro-morphological, two physical and two physico-chemical traits. Significant variation was observed among the cultivars for all the traits. Correlation analysis showed negative correlation of DFF with KLBC (r= -0.29; p=0.022) and kernel L/W ratio (r= -0.25; p=0.003), while PL was significantly and positively correlated with KLBC (r=0.38; p=0.000) and kernel L/W ratio (r=0.43; p=0.0649). KLBC showed highly significant positive correlation with GC (r=0.22; p=0.614) while between AAC and GC a significant negative correlation was observed (r= -0.38; p=0.000).

      Abstract: The development and implementation of ICT based pest monitoring and advisory system was an innovative idea to speed up the process of providing timely and correct pest management advice to the farmers. The system captured a total of 20,754 pest incidence, recorded through pest-specific scientific methods during 2018–20 and produced reports of pest status in farmer fields vis-a-vis pest ETL. Based on these pest reports, experts submitted 1,971 pest management advisories into the system which were disseminated to 7000 registered farmers of 9 districts of the state, through 4,49,465 SMSs during the years. The timely availability of correct pest management information greatly helped in minimising crop losses. The system also helped in the quick identification of pest hot spot areas and thus preparing the state agencies to effectively manage the pest problems in those areas. This also helped in the promotion and awareness of integrated pest management among the farmers. Implementation of appropriate pest management strategies by the farmers led to increasing in crop yield and avoidance of pest epidemics during the period. Besides, the system created a centralised pest data repository which could be utilised for drawing inferences in future. Such a database combined with a weather database could be a potential source for the development of forewarning models of insects and diseases.
