  • Allylic and Non-allylic Alcohols Against the Maize Weevil (Sitophilus
           zeamais): A Promising Tool for its Control

    • Free pre-print version: Loading...

      Abstract: Abstract The maize weevil, Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae), is a primary pest that mainly affects corn kernels during storage in silos. We evaluated the insecticidal activity by fumigation at 20 days and repellence of eleven allylic and non-allylic alcohols against S. zeamais and phytotoxicity of these compounds on corn kernels. Representatives of both groups, the allylic alcohols 1-octen-3-ol, trans-2-hexenol, and linalool and non-allylic alcohols 3-octanol and 1-hexanol showed high mortality values (> 72%) and repellency on maize weevils. A study of structure/activity relationship (QSAR) showed that the electric charge on carbon-bearing hydroxyl group is important in determining the insecticidal capacity. The tested alcohols generally did not cause a significant phytotoxic effect on grains. In conclusion, the compounds 1-octen-3-ol, linalool, 3-octanol, and 1-hexanol could be a good tool for S. zeamais control in silos because they induce high mortality, have the ability to repel insects, and are not phytotoxic to maize grains.

  • Wheat (Triticum aestivum) Establishment Methods and Microbial Inoculation
           for Improving Soil Microbial Properties and Crop Productivity

    • Free pre-print version: Loading...

      Abstract: Abstract Adoption of innovative crop establishment practices relies on the type of impact on soil-plant-water complex, rather than just crop productivity. Hence, a field experiment was conducted to study the impact of wheat establishment methods (WEMs) on soil biological properties as well as crop and water productivity. Three wheat establishment methods (WEMs), viz., drill-sown wheat (DW), wheat intensification system (WIS) and zero till-drill wheat (ZTDW) were selected along with two sources of nutrients, viz. chemical fertilizers and microbial inoculation Significant changes in the soil and plant-related aspects, particularly an improvement in soil microbiological properties such as acetylene reduction activity (ARA) (2.7–11.8%), soil chlorophyll (0.6–21.1%), dehydrogenase activity (1.1–10.8%), microbial biomass carbon (0.5–2.1%) and alkaline phosphatase activity (1.3–9.0%) at 90 days after sowing (DAS) in ZTDW over DW and WIS were recorded in the two-year field study. The highest values were observed with the application of 75% recommended dose of nutrients (RDN) (90 kg nitrogen ha−1 and 19.35 kg phosphorus ha−1) + Anabaena–Pseudomonas biofilm formulation + Zn. The soil microbiological parameters such as dehydrogenase activity, microbial biomass carbon and alkaline phosphatase activity also showed a significant increase due to the application of 100% RDN indicating that the application of fertilizers induced beneficial changes in soil-plant-water system. Interestingly, microbial inoculation had an economic impact on wheat which recorded an increase in grain yield by 200–230 kg ha−1 and water productivity by 0.45–0.53 kg ha-mm−1. The contribution of zero till-drill wheat to improvement in grain yield and water productivity was 240–260 kg ha−1 and 0.54–0.58 kg ha-mm−1, respectively. ZTDW and application of Anabaena–Pseudomonas biofilm formulation with 75% RDN led to significant and positive impacts on the biological activities in the rhizosphere of wheat.

  • Consumption of Mineral Fertilizers in the Polish Agriculture – Trends
           and Directions of Changes

    • Free pre-print version: Loading...

      Abstract: Abstract Balanced, rational fertilization determines high and valuable yields of crops. Polish agriculture has been considered traditional, pro-ecological, with relatively low consumption of agrochemicals for many decades. Transformations in the economic and social area, in particular Poland’s accession to the European Union, have significantly changed this picture. This paper presents the results of the research on the trends in fertilizer consumption in the Polish agriculture. The main time range of the analyses covered the period of 2013–2017. The source materials used in the study were statistical data for the entire country and provinces, published by the Central Statistical Office (GUS), as well as results of empirical studies. According to analyses, the pressure associated with the increase in the use of mineral fertilizers in Poland is growing. In the economic year 2017/2018, the average consumption of mineral fertilizers in Poland was at a level of 141.6 kg NPK per hectare of agricultural lands and was higher by 39.2 kg than in the 2004/2005 season. The empirical studies were carried out in six randomly selected provinces in Poland. Total 1034 surveys completed by farmers were analysed. Comparative analyses were carried out using a multiple correspondence analysis (MPA). Based on the analysis performed, it can be stated that the direction of changes in the consumption of fertilizers depends on the area and economic size of the agricultural holding as well as on the district in which the agricultural holding is located. The article points out problems in the area of sustainable fertilizer consumption in Poland (high consumption of nitrogen fertilizers, low level of soil liming, etc.). Perspective directions of changes (precision agriculture, innovative fertilizers, increased farmers’ awareness of nutrient efficiency and reduction of negative impact on the environment) were also summarized.

  • Comparison of Genetic Variability and Trait Association for Yield
           Contributing Traits among F2 Populations Generated from Wild Introgression
           Lines of Rice

    • Free pre-print version: Loading...

      Abstract: Abstract Wild introgressions play a crucial role in improving the genetic diversity of a cultivated varieties and also act as an important source for novel alleles for crop improvement. High-yielding stable backcross introgression lines identified from inter-specific crosses of Swarna cv. Oryza sativa with Oryza nivara were crossed among each other and also with parent Swarna. The F2 populations generated from 5 crosses, viz. Swarna x 166S (C1), 166S x 14S (C2), 166S x 148S (C3), 65S x 248S (C4) and 166-2S x Swarna (C5), were evaluated for 7 phenotypic traits in field conditions. Phenotypic data were analysed for genetic variability and trait association in each population individually. Descriptive statistics and correlation of yield traits in the population and the comparison among all five populations were estimated. Among the populations, C2 showed the highest average trait values for single plant yield, tiller numbers, productive tillers and harvest index. Highest range of phenotypic variation for single plant yield was also observed in C2 followed by C5; however, wide range of variation for plant height and biomass was observed in C3 and C5. Single plant yield showed significant association with all the 7 traits consistently across the populations. Plant height and biomass also showed significant variation in trait association with other traits under study. Development of mapping populations by crossing among backcross introgression lines is a useful strategy to pyramid multiple traits of interest with minimum donor introgressions.

  • Effect of Different Postharvest Chemical Treatments on Ethylene
           Production, Respiration Rate and Vital Heat of Stored Broccoli Heads

    • Free pre-print version: Loading...

      Abstract: Abstract The present study was conducted to investigate the effects of two concentrations of each chemicals viz., 6-Benzylaminopurine (6-BAP) (0.0025 and 0.005%), calcium chloride (CaCl2) (0.05 and 0.10%), ascorbic acid (0.5 and 1%), potassium permanganate (KMnO4) (0.5–1 g) and distilled water (assigned as control) on postharvest response of broccoli heads stored under ambient (20 ± 2 °C and 55 ± 2% RH) and refrigerated (4 ± 10c and 85 ± 2% RH) conditions. The experiment results suggested that the most pronounced effect was under 6-BAP treatments (i.e. 0.0025 and 0.005%) which reduced the respiration rate, liberation of ethylene, and vital heat in treated broccoli heads under ambient and refrigerated storage when compared to other chemical treatments. Further, heads treated with 6-BAP resulted in delay in yellowing of broccoli florets and aided to increase in shelf life up to 5.5 days and 23.5 days under ambient and refrigerated conditions, respectively.

  • Agronomic Characterization of the ‘Trompito INTA’ Persian
           Walnut Cultivar

    • Free pre-print version: Loading...

      Abstract: Abstract ‘Trompito INTA’ is a walnut cultivar of Argentine origin, developed at the Catamarca Experimental Station of the Instituto Nacional de Tecnología Agropecuaria (INTA). It was produced in 1984 by controlled pollination between the Persian walnut cultivars ‘Lompoc’ x ‘UC 56–224’. It has a very early to early sprouting and flowering, and it is protandrous with 30–70% overlap between pollen shedding and pistillate flower receptivity. Its harvesting occurs 28 days earlier than that of ‘Chandler’. The tree has weak vigor, semi-upright growth habit, medium density of branches and lateral fructification. The nut is of very large size (37.12 mm), the shell is thin, the kernel color is very light, and kernel percent is very high (> 53.5%). ‘Trompito INTA’ has early harvesting, high-quality nut and kernel attributes and better agronomic performance than ‘Chandler’, mainly at lower elevations. This cultivar is allowing the expansion of the crop in the province of Catamarca, lowering the limit of altitude for walnut cultivation.

  • Temperature Dependent Development of Myzus persicae Sulzer (Hemiptera:
           Aphididae) in Cauliflower (Brassica oleracea var. botrytis)

    • Free pre-print version: Loading...

      Abstract: Abstract Current predictions suggest that global mean temperature rise up to 3.4 °C by 2100 and such change is unlikely to affect the synchrony of growth and development of the insect pests. Experiments were undertaken to study the life history of Myzus persicae in cauliflower at six various constant temperatures under Open Top Chamber which in place the results revealed that the life span of M. persicae decreased with increase in temperature. The total life span extended to a maximum of 19 days at 34 °C which was as short as 14 days at 39 °C. The entire nymphal period and adult longevity were 5.34 and 13.48 days at 34 °C and declined to 2.90 and 11.46 days, respectively, at 39 °C. At 34 °C, fertility per female per day was 2.58 which increased with increased temperatures (4.78 at 39 °C). The age-specific survivorship decreased with the progress of age and 50 percent mortality was observed to be occurring earlier at all the temperature levels. In general, M. persicae tend to be ‘r’ favoring at lower temperature and shifted to ‘K’ favoring at higher-temperature conditions. Life table parameters, viz., gross reproductive rate (47.93), intrinsic rate of increase (0.467) and finite rate of increase (1.595), increased with increase in temperature of 39 °C. Mean generation time (6.23) and population doubling time (1.485) decreased with higher temperature. However, the net reproductive rate at 34 °C (24.40) was increased up to 36 °C (24.78) and found declined at higher temperatures (18.34 at 39 °C). The results indicated that the temperature above a threshold is detrimental to insect growth.

  • Cytoplasmic Types of Indian Potato Cultivars and Their Effect on Important
           Agronomic Traits

    • Free pre-print version: Loading...

      Abstract: Abstract Potato (Solanum tuberosum L.) is an important tuber crop that has vital role in the future food security of the world. It possesses different cytoplasmic (Cp) types which directly influence many important agronomic traits. Indian cultivars were screened for the Cp diversity and related traits like late blight resistance, total starch content and male sterility. Only T (83.63%) and D (16.36%) Cp type prevailed, while other types were totally absent. D Cp type was introduced for late blight resistance and was found to be related to high total starch content and better processing attributes. The effect of Cp type and various R genes on imparting resistance to late blight was found to act independent to each other. In a crop like potato, where breeders are challenged by tetrasomic inheritance and vegetative propagation, organelle studies are expected to provide a better picture of available diversity which can better be utilized in designing the breeding programs.

  • Artificial Neural Network Approach for Hydrologic River Flow Time Series
           Forecasting

    • Free pre-print version: Loading...

      Abstract: Abstract Stream flows are highly non-linear and complex in nature in any hydrological system. Lack of data availability for modeling requires use of specific model with high accuracy and efficiency which are capable in generating accurate hydrological response. In this paper, capability of artificial neural network model was investigated by utilizing eight years’ (2009–2016) of daily river flow and rainfall data for the Sot river catchment in Uttar Pradesh state of India. For investigating the effect of variables on river flow prediction, four ANN models were calibrated and validated for the period of 2009 to 2014 and 2015 to 2016, respectively, using different combinations of input parameters. Accuracy of developed ANN models was assessed by four performance indicators, namely correlation coefficient, root-mean-square error, modified Nash–Sutcliffe efficiency and Modified Index of Agreement. The results of the study indicate that performance of ANN model improves drastically after including the lag 1 river flow as an input parameter. It is concluded that the ANN model has the ability to solve highly complex non-linear river flow prediction and can be further used for the generation of synthetic river flow data of the Sot river catchment.

  • Farmers' Perception on Climate Variability and its Effects in Ambassel
           District, Northern Ethiopia

    • Free pre-print version: Loading...

      Abstract: Abstract Ethiopia currently faces many critical climate-related challenges that affect the lives and livelihoods of smallholder farmers. It is important to understand how differently situated communities perceive climate variability. This study investigates farmers’ perception of historical changes in climate and associated effects on agriculture in Ambassel District, Northern Ethiopia. The study was based on multi-stage sampling techniques to select the study area and 147 sample household respondents. Both primary and secondary data were used for data analysis. Primary data were collected through a household survey, focus group discussion and key informant interviews. The collected data were analyzed using descriptive statistics. We used regression model to determine the relationship between historical climate data and yield for food crops. Chi-square tests were also employed to compare the difference among agro-ecological zones. The results revealed that majority of the farmer’s perceived changes in the level of local climate and experienced its effects over two decades. As a result, both crop and livestock production by smallholder farmers have already been adversely affected. The regression analysis revealed significant relationship between rainfall and crop yields, teff (Eragrostis tef) and sorghum, which was consistent with perceived impacts of climate variability on crop production. Significant relationship was also observed between maximum temperature and sorghum yield. Therefore, there is a need to introduce water-related interventions such as small-scale irrigation and water harvesting as a drought adaptation strategy.

    • Free pre-print version: Loading...

      Abstract: Abstract Developing the knowledge base concerning the agroforestry’s contribution to fodder production that integrate livelihood security, relieve forest pressure and safeguard ecosystem services is pre-requisite for sustainable development. The study investigated the extraction and consumption pattern of fodder and extent of livestock dependency on natural forests to evolve silvipastoral agroforestry strategy for revitalizing fodder security in forest-fringe landscape of Ganderbal district, Kashmir. A total of 222 households were selected from 5 sample villages adopting multi-stage random sampling technique for field survey. Both secondary and primary sources were used for data collection. Household data were gathered administrating well-structured interview schedule and non-participant observations. Simple descriptive statistics were employed to analyse the data. Results revealed that total fodder extraction from various sources was 27,066.21 tons/year @12.19 tons/household/year and the forests were exposed to fodder pressure of 11,995.92 tons/year (44.31%) posing ample degradation. Focusing on the socioeconomic and ecological aspects, silvipastoral agroforestry strategy is designed, the implementation of which on cultivable wastelands would secure 11,847.73 tons/year of green fodder, tree fodder of 3846.67 tons/year, fuel wood of 307.73 tons/year, small timber of 320.43 m3/year, grass seed of 8.46 tons/year besides income of $ 66.13/household/year and employment of 9.98 man-days/household/year. Economic viability of the silvipastoral agroforestry strategy confirmed NPV of $ 734,192.67, BCR of 3.57 and IRR of 155.73% @12% annual discount rate on 12-year rotation. The strategy proposed needs to be implemented to mitigate the present unsustainable fodder extraction, safeguard the future fodder crisis, eliminate the fodder pressure on forests besides socioeconomic improvement.

      Abstract: Abstract The purpose of this study was to uncover ground truth policy insights underlying the agriculture crisis from the perspectives of rural farm operations in Nigeria. The needs of rural farmers were otherwise not adequately reflected in national or regional economic development policies. The grounded theory formal method was applied using NVivo software. A focus group was conducted with 16 agricultural extension workers, who are an advanced category of educated experts acting as mentors to rural Nigerian farmers. Audio data were coded into thematic concept maps using discourse analysis. The findings of this study were generally consistent with the extant literature, but several different issues emerged. Rural farmers in Nigeria have significant agricultural challenges with government support in six core areas: farming input quality and dissemination, fair input subsidization, training, market facilitation, social responsibility to reduce corruption, and poverty.

  • Heterosis Breeding Could Improve Root and Stem Anatomical Traits
           Conferring Bacterial Wilt Disease Tolerance in Tomato Cultivars

    • Free pre-print version: Loading...

      Abstract: Abstract Twelve F1 hybrids developed through line × tester design along with seven parents were evaluated for fruit yield, quality, incidence of bacterial wilt disease and anatomical features of root and stem to study the manifestation of heterobeltiosis, and to understand the implication of anatomical characters towards tolerance against bacterial wilt disease. Two hybrids (Utkal Deepti × CLN-2764A and Utkal Kumari × CLN-2777G) registering substantial tolerance against bacterial wilt exhibited marked heterobeltiosis for fruit yield per plant and other component traits. Hypocotyls of the highly tolerant hybrid did not show any bacterial colonization in xylem tissues under light microscope even at 8 days of inoculation with native bacterial isolate. The potted seedlings of tolerant hybrid showed mean disease index of 1.16 even at 20 days of inoculation with bacterial isolate which indicated promise for its utilization in bacterial wilt prone areas. Establishment of significant negative correlations between the incidence of bacterial wilt disease and the ratio of large vessels/small vessels in stem, diameter of large vessels in stem, and diameter of large vessels in roots suggested that these anatomical characters might be considered as important indices for selection of hybrid tolerant to bacterial wilt disease. Significant heterobeltiosis was also manifested for three anatomical traits. This study justified the scope of utilizing the anatomical features of stem and root in breeding tomato cultivars tolerant to bacterial wilt disease. Overwhelming response of non-additive genetic control for these anatomical traits also exposed the evidence of heterosis breeding for their improvement.

  • On-Farm Management of Soybean (Glycine max) Varietal Diversity in Southern
           and Central Regions of the Republic of Benin

    • Free pre-print version: Loading...

      Abstract: Abstract Soybean (Glycine max L. Merr) is a legume that contributes to food security and poverty reduction in Benin. Unfortunately, its culture is subject to several undocumented constraints that contribute to decline in productivity and a loss of diversity. Therefore, documentation of production constraints, varietal diversity seed system and traditional uses of soybeans in main production area of Benin Republic is necessary for its conservation and sustainable use. To fill these gaps, 57 villages were prospected in southern and central Benin using the tools and techniques of participatory research such as individual surveys using a questionnaire and field visits. A total 445 soybean producers were surveyed in the study area. The results show that soybean local nomenclature and local taxonomy were mainly based on seeds size. Thirty-five soybean local varieties were recorded corresponding to 7 varieties differentiated by morphological seed characteristics. The number of soybeans local varieties ranged from 1 to 4 per village. Farmers have abandoned some soybean local varieties and the main reasons for abandonment were agronomics. Eight varietal preference criteria were identified in the study area with high yield and seed size being important. The ravages of hares and rabbits were the main constraints to soybean production in both region. The soybean seed system was essentially informal. Various uses (food, feed and commercial) of soybeans, which underlie its conservation in traditional Beninese agriculture, have been recorded. As part of the development of conservation strategy of an existing soybean diversity in southern and central Benin, morphological and molecular characterization were recommended.

  • A Scientometric Analysis of Research on Pulses in India During
           2000–2017

    • Free pre-print version: Loading...

      Abstract: Abstract Food legumes, especially pulses, have a significant role in ensuring food and nutritional security of human and animal population. India is the largest producer of pulses in the world, accounting for 28% of the global pulses production. The current study evaluates the trends in research on pulses in India. The research productivity data for the period from 2000 to 2017 were extracted from Web of Science. A total of 7408 research items were published on pulses from across the world, and India ranked fourth (n = 701 publications), following Brazil, USA and Canada. The number of papers published in a year from India ranged from 17 (2003) to 72 (2016). Legume Research (n = 206) and Indian Journal of Agricultural Sciences (n = 128) carried almost 48% of the research publications on pulses from India during the period of analysis. The State Agriculture Universities and central research institutes in India play a vital role in addressing the knowledge gaps in various aspects of pulses research apart from the international institute based in India. Indian researchers published 58 research papers in collaboration with 24 foreign countries, and USA was the top collaborator. The research papers from USA were found to have the maximum citations (19,943). The impact of research on the production of pulses would have a differential lag period ranging from a few months to few decades based on the type of research. While research contributes in enhancing productivity of pulses, the state policies and schemes influence their area coverage and production. The study calls for constant policy support and increased investment on pulses research to bridge the yield gap.

  • Genotype-Environment Interaction for Quality Traits in Tomato Hybrids

    • Free pre-print version: Loading...

      Abstract: Abstract Breeding for quality traits in tomato has got boost due to enormous consumer and industrial demand owing to its exceptional nutritional benefits and attributes required for processing industries. Newly evolved varieties/hybrids need recommendation based on their adaptive specificity as a consequence of genotype-environment interaction. Hence, present study analysed comparative stability of 30 hybrids of tomato along with one check hybrid (To 3150) for important quality traits viz., total soluble solids (TSS), titrable acidity, ascorbic acid, carotene and lycopene content based on data of three locations over two years. The identified stable hybrids were Columbia × EC 538380, H 86 × EC 620541 and EC 620541 × EC 620438) for TSS, Superbug × EC 620438 for titrable acidity, Columbia × EC 620438 for ascorbic acid and NDTVR 73 × EC 620541 for carotene content. None of the hybrids was found stable for lycopene content. Stability for one trait was independent of stability of other traits. The responsive hybrids were Columbia × BS 24–2 (for TSS and carotene content), EC 521087 × EC 538380 (for ascorbic acid and carotene content), EC 620438 × EC 538380 (for ascorbic acid, carotene and lycopene content). The environments of Varanasi during both the years had favourable effect on all quality traits except carotene content as evident from environmental indices. The hybrids identified as stable are broad-adapted and can be recommended for general cultivation under different locations while the hybrids identified as responsive can be recommended for specific environments only.

  • Zinc and Iron Profiling in Edible Parts of Some Common Vegetable and Fruit
           Crops: An Exploration of Inter- and Intra-Crop Variation

    • Free pre-print version: Loading...

      Abstract: Abstract Zinc and iron malnutrition is a serious global public health burden largely faced by the developing countries particularly of South-East Asia and Africa. To overcome this, dietary diversity characterized by consumption of ample quantities of vegetables and fruits are often advised. Herein lies the need for screening of different vegetable and fruit crops to have an idea about their inherent ability for zinc and iron accumulation and variability present among their gene pools, which was thus taken as objective of the study. Two predominantly grown crops of each group (viz., vegetables—brinjal, pointed gourd and fruits—mango, banana) along with their available genepools were selected for the purpose. Results showed that zinc and iron accumulation in the edible parts varied significantly among the tested crops, following the order: pointed gourd > brinjal > banana > mango; but there was minimum variation among their respective genepools; native zinc concentration was found to follow the order: mango > pointed gourd > banana > brinjal; whereas native iron concentration followed the order: banana > pointed gourd > mango > brinjal. Thus it can be apprehended that, though these vegetable and fruit crops have the ability to supply a good amount of zinc and iron to our daily dietary intake, there is not much scope for further enhancement of the nutrients in these crops through conventional breeding method owing to the minimum inherent variations among the respective genepools of the crops with respect to zinc and iron accumulation in their edible parts.

  • Post-harvest Constraints of Solanaceae Species Produced in Kabare
           Wetlands, Eastern Democratic Republic of Congo

    • Free pre-print version: Loading...

      Abstract: Abstract The Kabare territory wetlands produced a significant quantity of solanaceous crops (potato, tomato and eggplant, etc.). One of the observations is the fact that significant losses are being observed during production and mostly after harvesting. The objective of this study was to assess the post-harvest constraints of the main solanaceous crops grown in these wetlands. A survey was carried out among 225 randomly selected households from four wetlands that lied down six districts to characterize the producers, identify the post-harvest techniques used and the constraints observed. Samples of solanaceous products were preserved for 15 days according to the local preservation techniques used to evaluate their effectiveness. The results showed that the producers face numerous post-harvest constraints of three types: structural, technical, and technological. These constraints a varied from value chain actor group to another. Most of the methods used by producers were mostly classified as moderately effective, and did not allow the quality of the products to be preserved, while quantitative losses remained very significant high. Besides, other external factors such as environmental and socio-economic factors contributed significantly also to these losses. Much losses are observed on tomato than on potato and eggplant; only a few preservation methods were classified as effective, notably tuber sorting (– 60%), the use of ice cubes (– 65%), and the use of pesticides (– 70%). Methods such as spreading out in a corner of the house (60%) and storage in the bag (50%) were classified as less effective for more than half by the farmers. Although suffering significant losses, these solanaceous crops provided important household income and thus contributed to food security in the area. Crop production and preservation have to be improved while effective production practices in Kabare and South-Kivu wetlands, eastern of DR Congo, have to be implemented.

  • Variation in Morpho-Agronomic Traits of Lowland Rice (Oryza Sativa)
           Genotypes of Assam in Response to Phosphorus Fertilization

    • Free pre-print version: Loading...

      Abstract: Abstract The present investigation was conducted with twenty-four genotypes (sub-plot) in two phosphorus doses (main plot) in a split-plot design with three replications during the Sali season (July-December) of 2017 at ICR farm, AAU. The ANOVA for 15 characters studied revealed significant variation between the phosphorus doses (0 and 20 kg P2O5 ha−1) for days to heading and 50% flowering, root length and root volume per hill. A highly significant variation among the genotypes was observed for all the 15 characters. The genotype and phosphorus interaction effects were significant for panicle length, filled grains/panicle, chaffs/panicle, spikelet fertility, 1000-grain weights, root length, root dry weight and root volume. A significant advance in days to heading and 50% flowering along with an enhancement in root length and volume was registered for 20 kg P2O5 ha−1. Among the 24 genotypes, only 7 genotypes, namely Herapoa, Gondhi Biroin, Pankaj, Prabhat Sali, Gheu Bora, Betguti-2 and Tulsi Bora, were categorized as high performing on the basis of total scores worked out of all the characters. Among the 3 diverse variety groups, glutinous genotypes contained the highest number of high yielding and phosphorus efficient genotypes followed by normal Sali, while the aromatic rice had only intermediate types. The genotype Herapoa proved to be highly phosphorus efficient based on mean grain yield and grain yield efficiency index (GYEI). This study proved the presence of P-efficient genotypes among the rice landraces of Assam to be used in breeding for low input or organic farming.
