  • Mechanical Properties of Cashew Nut Under Compression Loading at Varied
           Moisture Contents
    • Authors: Shrikant Baslingappa Swami; Nayan Singh J. Thakor; Asmita M. Gawai
      Abstract: In the present study, the moisture-dependent mechanical properties, i.e. rupture force, deformation and rupture energy along three different axes (i.e. L, B, T), of the cashew (Anacardium occidentale) varieties (Vengurle 1, Vengurle 3, Vengurle 4 and Vengurle 7) were studied at 17–85% db under compression loading. The rupture force decreases linearly (r2 ≥ 0.752) with the increase in moisture content from 17 to 85% db, for Vengurle 1 along length, width and thickness of 15,080–3467, 17,000–4275 and 21,014–3388 g; for Vengurle 3 along length, width and thickness of 25,090–4031, 26,000–3851, 31,256–3449 g; for Vengurle 4 along length, width and thickness of 22,000–3342, 21,000–3360, 27,000–3725 g; for Vengurle 7 along length, width and thickness of 20,900–5542, 25,080–5542 and 29,000–7009 g, respectively. The deformation at rupture increases linearly (r2 ≥ 0.671) with the increase in moisture content from 17 to 85% db, for Vengurle 1 along length, width and thickness of 2.1–2.98, 2.42–3.56 and 3.4–6.21 mm; for Vengurle 3 along length, width and thickness of 2.8–4.73, 2.65–4.3 and 4.21–6.16 mm; for Vengurle 4 along length, width and thickness of 4.2–6.89; 2.81–5.35 and 5.6–6.7 mm; for Vengurle 7 along length, width and thickness of 4.56–7.8, 3.2–5.56 and 6.2–7.27 mm, respectively. The rupture energy decreases linearly (r2 ≥ 0.720) with increase in moisture content from 17 to 85% db for Vengurle 1 along length, width and thickness of 143–36.58, 108–56 and 123–80.38 mJ; for Vengurle 3 along length, width and thickness of 271–59.54; 82.00–33.68 and 265–101 mJ; for Vengurle 4 along length, width and thickness of 136–80.96, 58.54–23.32 and 154–96.74 mJ; for Vengurle 7 along length, width and thickness of 273–98.26, 123–21.22 and 255–151 mJ, respectively. The rupture force was higher along thickness and decreases along width and length, and it was maximum for Vengurle 3 followed by Vengurle 7, Vengurle 4 and Vengurle 1. The deformation at rupture was higher along the thickness and decreases along width and thickness and was maximum at Vengurle 7 followed by Vengurle 4, Vengurle 3 and Vengurle 1, respectively. The rupture energy was higher at length for Vengurle 7 and decreases at Vengurle 3, followed by Vengurle 1 and Vengurle 4 along length of the cashew nut.

  • An Evaluation of the Resilience of the Regional Agricultural Water and
           Soil Resource System in Heilongjiang Province, China
    • Authors: Dong Liu; Ran Mu; Qiang Fu; Chunlei Liu; Tianxiao Li; Khan M. Imran; Song Cui; Faiz M. Abrar
      Abstract: Water and soil resources are fundamental natural resources. Therefore, it is highly important to understand the resilience of regional water and soil resources, the characteristics of which are nonlinear, self-organized and unpredictable. This study used a projection pursuit model based on the firefly algorithm (FA-PP) to quantitatively evaluate the water and soil system resilience of 15 farms in the Jiansanjiang administration of Heilongjiang Province, China. The results were compared with the results obtained by the projection pursuit model based on the genetic algorithm (GA-PP), and the validity and feasibility of the FA-PP model were verified. Further analysis revealed that the key factor influencing the resilience of agricultural water and soil resources was the irrigated area. The research results revealed the restoring situation of the local water and soil resource system and provided a foundation for the management of agricultural water and soil resources.

  • Modelling the Grain Yield of Wheat in Irrigated Saline Environment with
           Foliar Potassium Fertilization
    • Authors: M. Kumar; A. Sarangi; D. K. Singh; A. R. Rao
      Abstract: In the present study, an effort was made to calibrate and validate a crop model using the experiment generated data pertaining to growth and yield of wheat cultivars under irrigated saline environment using foliar potassium application. A field experiment was conducted at Water Technology Centre research farm, Indian Agricultural Research Institute, New Delhi, in split–split plot design during rabi 2011–2012 and 2012–2013 to generate data for simulation of FAO AquaCrop model. Two wheat cultivars (i.e. one salt tolerant KRL-1-4 and other salt susceptible HD 2894) under four salinity levels, viz, GW (1.7 dS m−1), 4, 8 and 12 dS m−1 were experimented under foliar and non-foliar treatments. AquaCrop model was calibrated using experiment data of rabi 2011–2012 and validated with data of rabi 2012–2013. The model evaluation parameters, viz, model efficiency (ME), index of agreement (d) and R2 pertaining to grain yield of both wheat cultivars predicted by validated model were averaged to be 0.86, 0.95 and 0.96, respectively, under all treatment levels. Moreover, the simulated biomass yield of both the cultivars was with average values of ME, d and R2 as 0.91, 0.97, and 0.93, respectively. However, model validation results for water productivity were 0.60, 0.82 and 0.93 for ME, d and R2, respectively. It was observed that the AquaCrop model simulation for grain yield was better as compared to biomass and water productivity for all treatment levels. Validated model resulted in predicted grain yield of both wheat cultivars with low prediction error (i.e. 1.77–6.52%) up to 8 dS m−1, whereas at 12 dS m−1 salinity level, the prediction error increased and varied from 21.7 to 37.5%. Nonetheless, the FAO AquaCrop model can be used with acceptable accuracy for simulation of grain yield of wheat cultivars using saline irrigation up to 8 dS m−1 with foliar potassium fertilization.

  • Influence of IAA and ACC Deaminase Producing Fluorescent Pseudomonads in
           Alleviating Drought Stress in Wheat ( Triticum aestivum )
    • Authors: Dinesh Chandra; Rashmi Srivastava; A. K. Sharma
      Abstract: Drought is one of the major constraints limiting agricultural production worldwide. Soil bacteria containing 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase and indole acetic acid (IAA) producing traits with the potential for the alleviation of drought stress in combination with plant growth promotion would be extremely useful tools in sustainable farming. The present study was undertaken with two drought-tolerant bacteria Pseudomonas fluorescens strain DPB15 and P. palleroniana strain DPB16 containing ACC deaminase activity as isolated from rainfed agriculture areas of Kumaun regions of Uttarakhand, India. There were two sets of pot trails, i.e., non-stressed (watered) and drought stressed (non-watered). The growth parameters were recorded after fifty-four days of growth. Bacterial inoculation enhanced the growth of wheat in terms of root and shoot biomass, height and foliar nutrient content in treated as compared to untreated plants. In addition, a significant increase in antioxidant activity (SOD, CAT, GPX and APX) was also observed where bacterial treatment improves the plant fitness by protecting it from the oxidative damage created by drought. A correlation study between non-enzymatic and enzymatic antioxidants demonstrated that a perfect positive significant correlation between SOD and Chl, GPX and Pro, CAT and H2O2, and CAT and TPC; a perfect negative correlation between TPC and H2O2; and for others parameters nonsignificant correlation were observed under water-stressed conditions.

  • Inheritance of Seed Longevity and Its Association with Other Seed-Related
           Traits in Soybean ( Glycine max )
    • Authors: Amit T. Adsul; Vivek P. Chimote; Milind P. Deshmukh
      Abstract: Soybean seeds are highly susceptible to field weathering and mechanical damage during storage, thereby adversely affecting their longevity. To study the inheritance of seed longevity crossing was undertaken between two well-adopted genotypes (DS-228 and MAUS-71) having low seed longevity and two genotypes (Birsa Soya-1 and Kalitur) having high seed longevity and their total of 1138 F2 segregants were subjected to accelerated ageing test. F2 population data for seed longevity trait fitted in 3:1 Mendelian ratio indicated that it was governed by a single major gene in all the four crosses was further confirmed by test cross which fits the ratio 1:1. The segregants obtained from this study could be utilized for the development of high seed longevity soybean breeding program. The results of various six generations (P1, P2, F1, F2, B1 and B2) of four crosses exhibited varietal differences in seed vigour as clearly evident by standard germination after 8 days of accelerated ageing (ranged from 53.16 to 83.09%). Seed longevity had a positive association with germination percentage, seed density, proportion of the seed coat and lignin content in all four crosses, while seed coat permeability had negative association. The black-seeded parents were found to inherit good storability trait to their yellow-seeded progenies.

  • Enhanced Techniques of Soil Washing for the Remediation of Heavy
           Metal-Contaminated Soils
    • Authors: Xu Yang; Xinyu Mao; Xiaohou Shao; Fengxiang Han; Tingting Chang; Hengji Qin; Minhui Li
      Abstract: Soil washing has been developed as one of the ex situ traditional remediation methods for heavy metal polluted soils. It has been found to be effective in metal extraction. However, due to the distribution and speciation in soils, most metal(loid)s are present in less mobile forms which limit the washing efficiency. Therefore, methods are studied to enhance the washing performance by increasing the metals solubility and availability. This paper introduces some currently used methods and technologies, including the optimization of washing variables, lowering soil pH, application of assisted amendments and integration of electro-kinetic remediation and ultrasonication to enhance the removal of metals. In addition, it also suggests some further studies.

  • Genetic Study of Horticultural Traits in Bell Pepper ( Capsicum annuum
           var. grossum ) Through Generation Mean Analysis
    • Authors: Jyoti Devi; Sonia Sood
      Abstract: The present investigation was carried out at CSK HPKV, Palampur (Himachal Pradesh, India), to study gene action for important horticultural traits in bell pepper and to develop desirable breeding material from the segregating generations. In this study six generations (P1, P2, F1, F2, B1 and B2) of four crosses, viz, EC-464107 × Kandaghat Selection (C1), EC-464115 × Kandaghat Selection (C2), EC-464107 × EC-464115 (C3) and EC-464107 × Sweet Happy-I (C4), were evaluated. The results of the scaling tests revealed that additive-dominance model was inadequate in all the crosses for all the traits studied. For total fruits per plant, the magnitude of dominance [h] gene effects and additive × additive [i] gene interactions were positive and higher coupled with duplicate epistasis in the crosses C1, C2 and C4. This suggested the exploitation of heterosis breeding as well as the selection of desirable segregants through the pedigree method in these crosses. For total fruit yield per plant, all the four cross combinations revealed positive and relatively higher magnitude of dominance [h] gene effects along with complementary gene action in the cross C3 and duplicate type of epistasis (but low magnitude) in the cross C4. This suggested the usefulness of exploiting hybrid vigor in these crosses. Studies on the extent of heterosis suggested that the F1 hybrid EC-464107 × SH-I (C4) was the most consistent for earliness, while the cross EC-464107 × KS (C1) was more reliable for high fruit yield and can further be evaluated for yield and quality traits as well as resistance to bacterial wilt.

  • Theoretical Determination of a Critical Nitrogen Dilution Curve Based on
           the Carrot Case Study
    • Authors: Eli Shlevin; Arkadi Zilberman; Jiftah Ben-Asher
      Abstract: The objectives of the present study were to: (a) formulate a general dilution equation for a critical nitrogen percentage in a leaf (Nc); (b) monitor dilution function of carrot as a case study; (c) demonstrate applicability of digital color imaging to monitor total nitrogen (Ntot) in crops. Carrot (Daucus carota) was grown on loess soil at five Ntot application rates. Ntot weight (kg/ha) was obtained by standard laboratory analysis and by image processing. Total yield of the treatments was the sum of canopy and roots dry matter. A new logistic decay curve Nc = a/[1 + (W/W0) b ] agreed with experimental data. Nc (g/kg) is the critical nitrogen level, a and b are coefficients, and W/W0 is the relative dry matter biomass. Values of Nitrogen Nutrition Index (NNI) ≥ 1.0 indicated that there was no nitrogen deficiency in treatment larger than 100% application of Ntot. The weight of nitrogen in form of multiplication of the dry leaves weight (W) and N percent is suitable for the determination of nitrogen status. The availability of image-based data for N percent is faster, timely and less expensive than that of laboratory test. Applicability of digital color camera to monitor Ntot in crops instead of laboratory test was successfully demonstrated.

           Cucurbita moschata ) Genotypes
    • Authors: Arvind Nagar; Amish Kumar Sureja; Abhijit Kar; Rakesh Bhardwaj; S. Gopala Krishnan; Anilabha Das Munshi
      Abstract: The present investigation was carried out to estimate the extent genetic variability and character association for fruit yield and nine mineral nutrients (sodium, potassium, calcium, magnesium, iron, manganese, copper, zinc and selenium) in 76 genotypes of pumpkin during spring–summer season of the year 2014. The experimental results revealed significant differences among the genotypes for all the traits under study. Based on mean performance, the genotypes DPU-6, DPU-26 and DPU-51-3 were found most promising for different mineral nutrients and fruit yield per plant. Further, high heritability estimates coupled with high genetic gain were observed for all the traits under study, which indicated that these traits are under additive gene effects and are more reliable for effective selection. The correlation coefficients (phenotypic and genotypic) among different minerals along with fruit yield per plant depict that fruit yield per plant has significantly positive association with calcium (0.187 and 0.216) and magnesium (0.149 and 0.155) content. Path coefficient analysis at genotypic level revealed that iron has maximum positive direct effect (0.374) on marketable fruit yield per plant, followed by calcium (0.198) and copper (0.037). Besides, maximum positive indirect effect of manganese (0.331) and copper (0.265) via iron was observed on the fruit yield per plant.

    • Authors: Siladitya Bandyopadhyay; Prasenjit Ray; Shelton Padua; S. Ramachandran; Roomesh Kumar Jena; Partha Deb Roy; D. P. Dutta; Surendra Kumar Singh; Sanjay Kumar Ray
      Abstract: An attempt was made to identify priority zones of available micronutrients in the soils of agro-ecological sub-regions (AESR) of north-eastern states of India (Assam, Nagaland, Sikkim and Tripura) using geo-spatial techniques. Surface soil samples (0–25 cm) were collected from Assam (AESRs 15.2, 15.3, 15.4 and 17.1), Nagaland (AESR 17.1), Sikkim (AESR 16.2) and Tripura (AESR 17.2) and analysed for pH, organic carbon and DTPA-extractable micronutrients (Fe, Mn, Zn and Cu) by standard procedures. Regular Spline was employed as spatial interpolation techniques for obtaining spatial distribution of available micronutrients in soils. The AESR map was overlaid on spatial distribution layers to obtain spatial variability of micronutrients in the AESRs of north-eastern regions of India. Zinc deficiency was common in all the AESR. Maximum deficient area of Zn, Mn and Cu was observed in AESR 15.4, and it was regarded as the high-priority zone, whereas AESR 16.2 and AESR 17.2 were considered as low-priority zone. Rainfall, pH and organic carbon appeared to be the key factors in controlling micronutrient availability in soils of north-eastern regions of India.

  • Carbon Footprint of Crop Cultivation Process Under Semiarid Conditions
    • Authors: A. S. Devakumar; R. Pardis; V. Manjunath
      Abstract: Agriculture is one of the major sectors that get affected as well as cause climate change. Arid and semiarid regions of the world are expected to become more vulnerable to climate change. Thus, in order to develop appropriate mitigation or adaptive strategies, carbon footprint analysis of agriculture sector becomes crucial. Emissions resulting from the cultivation process depend on the inputs used and the environmental conditions. The present study is an effort to analyze the carbon footprint of agriculture crops cultivated in the state of Karnataka with 80% land under rainfed agriculture under semiarid tropical conditions. About 5.37 terra grams of carbon equivalent (TgCE) was found to occur annually. Cereals contributed 5.04 TgCE/year of which 78% comes from rice, as it emits methane in addition to CO2 and NO2. Possible approaches to reduce methane emission are discussed including the possibility of replacing the area under rice with other crops without affecting the dietary as well as peoples preferences. Inorganic nitrogen fertilizer use in the cultivation process accounts for 72% of the total emissions. Combining pulse crops effectively in conventional practices of crop rotation and mixed cropping systems can help in reducing emissions. Manual agriculture followed due to small land holdings facilitates low energy use (8%) under rainfed agriculture, resulting in low carbon input. Irrigated agriculture recorded 4.19 TgCE/year which is almost 3.5 times more than the rainfed agriculture practice. Among the two cropping seasons, Kharif season which is the major cropping season recorded 3.85 TgCE/year against 1.52 TgCE/year during Rabi season. Most tropical regions with fragmented land, low carbon emission as well as with the low productivity need to be treated differently.

  • Effect of Seasons on Subsequent Production Behavior of Small Size Potato
    • Authors: Ashwani K. Sharma; Tanuja Buckseth; R. K. Singh
      Abstract: For the effective utilization of healthy and precious planting material, one-time multiplication of extremely small mini-tubers of potato under protected conditions is an alternative option to improve the size of progeny tubers for making them suitable for field multiplication. With this objective, the extremely small potato mini-tubers, viz. < 1, 1–2 and 2–3 g, produced during Kharif and autumn seasons were evaluated for their production behavior and health status under polyhouse (aphid proof) conditions of northwestern India (2700 m above mean sea level) during 2012 and 2013. The study revealed that mini-tubers produced during both the seasons had almost similar production potential and can be multiplied simultaneously without any special treatment. The number of tubers/m2 was more with mini-tubers grown in Kharif season than the autumn ones, but the yield was similar with the mini-tubers from both the seasons. However, plant vigor, number of tubers and yield were significantly affected by the grade of mini-tubers. The ELISA test of 5% plants raised from the mini-tubers from both the seasons revealed 100% healthy stocks in all the grades of mini-tubers.

  • Micromorphological and Anatomical Evaluation of In Vitro and Field
           Transferred Plants of Coccinia indica
    • Authors: Mahipal S. Shekhawat; M. Manokari
      Abstract: The micromorphological and anatomical changes in micropropagated plantlets of Coccinia indica grown under field conditions were studied. In vitro regeneration of plantlets under heterotrophic conditions is responsible for the induction of plant’s physiological and structural modifications. Significant developmental changes were observed from in vitro to the in vivo shifted plantlets. The micromorphological alterations in terms of stomatal index (from 23.0 to 19.2), vein islets (from 6.2 to 11.5), trichomes (from 11.0 to 16.0), epidermal cells and mesophyll tissues revealed the effective metabolism of photosynthesis and respiration from in vitro to field environment. Abnormal hypertrophied cortical cells with large intercellular spaces and retarded vascular cells were reported from the in vitro grown stem and root, whereas compact storage cells and advanced vascular tissues with the development of secondary xylem and phloem tissues were observed in field transferred plants. Field transfer is stressful to the micropropagated plantlets, which could be repaired by maintaining in vitro regenerated plantlets in the greenhouse to induce the plasticity in the plantlets. This study could help in understanding the abnormal tissues organization and functions of stomata behind the poor acclimatization process which leads to the poor survival of micropropagated plantlets in the field.

  • Optimizing Dosage and Mode of Potassium Application for Rice in
           Drought-Prone Rainfed Ecology of Middle Indo-Gangetic Plains
    • Authors: Santosh Kumar; S. K. Dwivedi; K. K. Rao; J. S. Mishra; A. K. Singh; Narayan Bhakta; Ved Prakash; Shishir Kant Singh; Virendar Kumar; B. P. Bhatt
      Abstract: A field experiment was undertaken during wet seasons of 2014 and 2015 to evaluate the response of soil-applied potassium (K), and its additional foliar application in rice (Sahbhagi Dhan) under drought-prone rainfed lowland ecology of eastern India. Three K2O doses (20, 30, 40 kg ha−1) were soil applied alone, and also supplemented with two levels of foliar sprays (0.50 and 1.0% K, separately) at panicle initiation stage. The results indicated that growth and yield of rice were adversely affected in the absence of extraneous application of potassium in drought-prone environment. Under drought, K management practices significantly influenced grain yield and B:C ratio, recording its maximum (3.92 t ha−1 and 1.43) with 20 kg K2O ha−1 basal application + one foliar spray @ 1.0% K at PI stage which was at par with 40 kg K2O ha−1 basal application compared to control (3.25 t ha−1 and 1.22). Moreover, foliar application of potassium significantly improved the gas exchange process (Pn rate), water status in terms of RWC and chlorophyll content and TSS. Extraneous application of K, across different doses, application schedules and methods maintained higher K content in straw as well as in grain as compared to control. Our finding strongly suggests that split application of K is highly beneficial for improving nutritional quality without significantly declining yield under drought-prone ecology of rice where K is limiting factor.

  • Assessing Breeding Potential of Three-Way Cross and Double-Cross Hybrids
           in Chilli ( Capsicum annuum )
    • Authors: T. Lakshmi Pathy; A. Mohan Rao; S. Ramesh
      Abstract: Assessing breeding potential of multi-parent crosses is essential in order to isolate inbreds with broad genetic base. Five parental lines of chilli were used to produce ten single-cross hybrids in diallel design. These ten single crosses were in turn used to produce 15 double-cross hybrids and 30 three-way cross hybrids. The breeding potential of these three-way cross and double-cross hybrids was assessed for fruit yield per plant in terms of quantitative traits means, variances and their ability to produce transgressive segregants. Rank sums were also calculated based on individual means and variance. The hybrids which showed better values for all these parameters were compared and inferred that (Byadagikaddi × Gouribidanur) × (CCA 9907-9611 × Tiwari) and (CCA 9907-9611 × Tiwari) × PBC 483 have highest breeding potential and hence can be utilized for further improvement.

  • Enhancing Water and Phosphorus Use Efficiency Through Moisture
           Conservation Practices and Optimum Phosphorus Application in Rainfed
           Maize–Chickpea System in Vertisols of Central India
    • Authors: R. S. Chaudhary; J. Somasundaram; K. G. Mandal; K. M. Hati
      Abstract: Conserving soil moisture in the rainfed region is a challenging task as it plays a significant role in crop productivity and livelihood security of rainfed farmers. The soil moisture conservation practices (MCPs) coupled with the addition of root augmenting nutrition are crucial for sustaining crop yields and maintaining soil phosphorus (P) in a rainfed Vertisol of Central India. Thus, a study was conducted to evaluate the long-term effect of MCPs and P application in maize–chickpea in a Vertisol. A five-year study showed that the MCPs integrated with P nutrition significantly helped in growing chickpea (Cicer arietinum) without irrigation or with limited irrigation. Under the normal rainfall conditions such as normal onset time, distribution and cessation time during the experimentation, the MCPs proved useful in obtaining chickpea yields in the range of 776 to 933 kg ha−1. The best MCP was the practice of late intercultural operations + Gliricidia cover in the inter-row spaces of standing maize (@ 5 t ha−1 fresh weight basis) + maize stover application (after sowing up to germination), which recorded higher chickpea grain yield (932 kg ha−1) on account of higher moisture content in the soil and reduced stress in the plants. Another comparable treatment was Gliricidia cover + one pre-sowing irrigation of 6 cm for chickpea, which recorded 933 kg ha−1 of chickpea yield. Both the treatments recorded significantly higher yields than the under control (637 kg ha−1). We also found that the application of Gliricidia cover on the soil surface coupled with either pre-sowing irrigation and/or late intercultural operations had beneficial effect on soil physical conditions increasing soil moisture which in turn affected the crop growth. Under normal monsoon years, the best treatments (MCP4 and MCP5) recorded around 46% higher chickpea yield as compared to the control. It is concluded that these soil MCPs are very useful in rainfed areas for sustaining crop yield.

  • Identifying Sensitive Soil Properties as a Function of Land Use Change in
           Thar Desert of India
    • Authors: Mahesh Kumar; Priyabrata Santra; S. K. Singh; P. Raina; Amal Kar; Balak Ram; P. C. Moharana
      Abstract: Soil plays a critical role in earth’s biosphere by supporting the production of food, fodder and fiber. However, rapid land use changes in recent times in different parts of the world led to increasing concern on soil health. It has been realized that changes in land use systems significantly affect soil properties. Therefore, we studied the impact of land use systems on soil physicochemical properties in the Thar Desert of India. Surface soil samples (0–30 cm) from four land use systems: (1) sand dunes, (2) grazing lands, (3) rainfed croplands and (4) irrigated croplands have been collected and analyzed in laboratory to determine soil pH, electrical conductivity (EC), CaCO3 content, organic carbon content, available P content, available K content and micronutrients (Zn, Fe, Mn, and Cu) content. We observed higher clay, organic carbon and nutrient contents and lower bulk density values in irrigated croplands than in other land use systems. Soil pH and EC were higher in irrigated croplands than in the other land use systems. Principal component analysis of soil physicochemical properties revealed two major soil factors, the clay–carbon factor and salinity factor, which were able to significantly differentiate the land use systems. For irrigated croplands, the clay–carbon factor was found to be higher than the rest of the land uses; however, the salinity factor was the lowest. Higher values of these two factors will lead to a favorable soil physicochemical environment for plant growth or better soil health. These two factors may further be used for assessing the impact of land use systems on soil quality in other regions.

  • Simulating the Response of Sugarcane Production to Water Deficit
           Irrigation Using the AquaCrop Model
    • Authors: Omid Bahmani; Sahar Eghbalian
      Abstract: A water shortage has always been the main limiting factor of agricultural development in arid and semiarid areas. In this research, the yield response to water stress for sugarcane in Khuzestan, Iran, was studied using an AquaCrop model under deficit irrigation scenarios (2004–2010). Treatments were contained 100% (I1), 125% (I2), 85% (I3) and 70% (I4) of full irrigation. The results indicated that the simulating sugarcane yield was acceptable with normalized root-mean square error (NRMSE) = 1.89 and root-mean-square error (RMSE) = 1.7. The statistical analysis of yield showed that there was no significant difference between I1, I2 and I3 treatments. Simulating the water productivity (WP) was acceptable (NRMSE = 1.44 and RMSE = 0.06). All the treatments were significantly different than the treatment I1 in simulated WP. Agreement index for yield and WP (0.91 and 0.99) showed compatibility of these predicted values with the actual value. The results showed that the AquaCrop model is an appropriate tool to simulate sugarcane yield and water productivity under deficit irrigation conditions in Iran. According to the results, the I3 scenario can be recommended.

  • Genetic Control of Inheritance of Fruit Quality Attributes in Tomato (
           Solanum lycopersicum )
    • Authors: Jiregna Tasisa; Wassu Mohammed; Shimelis Hussien; Vasantha Kumar
      Abstract: The experiment comprised of seven tomato inbred lines (two processing and five fresh market) and 21 F1 hybrids produced by crossing of them in a 7 × 7 half diallel fashion excluding the reciprocals. The study was conducted at the Haramaya University, Ethiopia during July 2015 to June 2016 to analyze the genetics of inheritance of some physical and chemical quality traits. A randomized complete block design with three replications was used to conduct the experiment. Among the studied characters, only shape index and titratable acidity fulfilled the additive–dominance hypothesis. Therefore, non-allelic gene interaction could be involved in the inheritance of the characters which did not fit the model. The parental line Roma VF contained mostly recessive genes with increasing effects for shape index, and the parental lines Marglobe and Eshete contained mostly recessive genes with the increasing effects for titratable acidity. Therefore, employing these lines in hybridization for shape index and titratable acidity improvement could be ineffective, since the rapid increased frequency of recessive alleles which is the cause of loss of vigor could be resulted in advancing generation.

  • Seed Hydropriming Enhances Osmotic Stress Tolerance Potential in Vigna
    • Authors: K. C. Jisha; Jos T. Puthur
      Abstract: Green gram (Vigna radiata (L.) Wilczek) is a widely cultivated pulse crop in India, and it holds a key importance in food supplement due to its protein-rich edible seeds. This crop usually experiences abiotic stresses like drought and salinity during the cultivation period. The investigation was carried out to study the effect of hydropriming on osmotic stress tolerance potential of three Vigna radiata varieties, with varied abiotic stress tolerance potential. Hydropriming enhances the photosynthetic activities of the seedlings. Moreover, hydropriming resulted in reduction of proline content in Pusa Ratna and Pusa 9531 seedlings, whereas the salt-tolerant variety Pusa Vishal showed increase in proline content, especially under stressed conditions. Osmotic stress caused increase in MDA content in all the varieties studied, and this increase was significantly minimized by the influence of hydropriming. Hydropriming also enhanced the activities of antioxidant enzymes in the seedlings. From the results of this study, it is concluded that hydropriming of seeds improved the drought and salinity stress tolerance potential of all the three green gram varieties and it was significantly evident in the abiotic stress-sensitive variety Pusa Ratna as compared to Pusa 9531 (drought tolerant) and Pusa Vishal (NaCl tolerant).
