    Abstract: The present investigation was carriedout with 25 rice genotypes. The evaluation was taken under three different environmental locations based on 11 quantitative traits. The trials were laid out in RBD with three replications at Students Instructional Farm, MES (Main Experimental Station) and Agronomy Farm of A.N.D.U.A.T., Kumarganj, Ayodhya. The environment-wise analysis of variance and pooled analysis of variance for three environments covering one crop seasons, revealed high significant mean squares for all the eleven characters under evaluation. Considering the mean performance of genotypes for different environmental conditions, the genotypes viz. T-3, Kavery Sampoorna, NDRK-11-27, Moti Gold and NDRK-11-29 were exhibiting high mean performance for grain yield per plant and some of its important components under irrigated condition. Three genotypes, T-3, Kavery Sampoorna, NDRK-11-27 possessed highest grain yield per plant among 25 genotypes across three environments. A wide range of phenotypic and genotypic coefficient of variability was observed. The high magnitude ( 〉 20%) of PCV along with GCV observed for productive biological yield per plant (34.88), grain yield per plant (33.41%), L/B ratio (24.76) while high GCV recorded in biological yield per plant (31.00%), grain yield per plant (25.14%), no. of spikelet per panicle (21.15%). Moderate estimates of PCV along with GCV were recorded for harvest index (17.75%), panicle length (15.21%), plant height (13.6%) and days to 50% flowering (12.41%) and GCV were recorded productive tiller per plant (17.92%), harvest index (15.28%), leaf area index (13.81%), L/B ratio (13.55%), plant height (12.37%), days to 50% flowering (11.98%) and panicle length (10.75%).  The magnitude of heritability in broad sense varied between 93.28% in case of days to 50% flowering to 27.37% in case of L/B ratio. The high estimation of heritability recorded into days to 50% flowering (93.28%) followed by plant height (82.72%), biological yield per plant (78.99%), spikelet fertility (75.70%). moderate estimates of heritability were reported for harvest index (74.08%), productive tiller per plant (69.72%), number of fertile spikelet per panicle (66.78%). while low estimates of heritability were reported in case of L/B ratio (27.37), leaf area index (31.14%). High heritability along with high genetics advance in percent of mean was recorded for days to 50% flowering indicating the preponderance of additive gene action.

    Abstract: This study was conducted during Kharif, 2019 At the Students Instructional Farm, MES and Agronomy Farm of A.N.D.U.A.T., Kumarganj, Ayodhya, the trials were set up in RBD with three replications. The experimental material comprised of 25 genotypes of rice were evaluated for 11 quantitative traits under three different environmental locations. High significant mean squares were found for all eleven research characteristics in the environment-specific analysis of variance and the pooled analysis of variance for three environments encompassing one crop season. T-3, Kavery Sampoorna, NDRK-11-27, Moti Gold, and NDRK-11-29 under irrigated circumstances were the genotypes demonstrating high mean performance for grain yield per plant and some of its significant components when considering the mean performance of genotypes under various environmental situations. Out of 25 genotypes tested in three conditions, T-3, Kavery Sampoorna, and NDRK-11-27 had the maximum grain yield per plant.In path coefficient analysis highest positive direct effects on grain yield per plant was exerted by L/B ratio (0.281), followed by panicle length (0.167), number of fertile spikelet per plant (0.092) and days to 50% flowering (0.037). On the other hand, negative direct effects on grain yield per plant was exerted by plant height (-0.255), leaf area index (-0.195), spikelet fertility (-0.187), biological yield per plant and harvest index (-0.126) and productive tillers / plant (-0.049). Positive indirect effects on spikelet fertility was recorded via biological yield per plant (0.040) followed by panicle length via biological yield per plant (0.264), productive tiller per plant biological yield per plant (0.021) and plant height via biological yield per plant (0.011). Considering the mean performance and stability parameters, three high yielding genotypes T-3, Kavery Sampoorna and NDRK-11-27 merit due consideration for recommending their exploitation as cultivars or varieties for commercial cultivation and/or as donor for hybridization programme for wide range of environments pertaining especially to different environments. In addition to these genotypes, several other genotypes exhibiting high or average mean performance, desirable non- linear response and stable nature for different characters may also be useful for exploitation as parents in hybridization programme as donors for characters for which they showed superiority even if they had average or low grain yield per plant.

    Abstract: The study was conducted in 2023 with the aim of finding out the constraints perceived by members of FPOs in Varanasi District, Uttar Pradesh. The Varanasi district was purposively selected for the study, focusing on FPOs with more than 5 years of existence. Among the 29 registered FPOs in the district, only four FPOs met this criterion, namely; Kashi Vishwanath Farmer Producer Company Limited (KVFPCL), Rameshwar Farmer Producer Company Limited (RFPCL), Shivansh Krishak Producer Company Limited (SKPCL), and Jayapur Seed Producer Company Limited (JSPCL). The stratified random sampling method was used with proportional allocation. 35 respondents were selected from KVFPCL and RFPCL, while 25 from JSPCL, and 55 from SKPCL were selected proportionally to make the sample size of 150 respondents., ensuring a representative and comprehensive sampling approach across these four FPOs. The statistical analysis of the collected data was conducted using the Henry Garrett ranking technique. The results revealed four types of constraints perceived by the members of FPOs. In technical constraints, underdeveloped storage facilities ranked first with a GRS of 78.05, and underdeveloped processing facilities ranked second with a GRS of 70.44. In labour and economic constraints, the lack of skilled labour in harvesting and processing secured the first rank with a GRS of 73.12, while the shortage of labour during harvesting ranked second with a GRS of 62.69. Regarding marketing constraints, the fluctuation of prices every year came in first with a GRS of 65.24, and low produce prices ranked second with a GRS of 62.55. Lastly, in organizational and financial constraints, the lack of proper infrastructure claimed the first rank with a GRS of 62.67, while the absence of connections with financial institutions ranked second with a GRS of 49.36.These insights provide valuable guidance for enhancing the productivity and sustainability of FPOs in the region and similar contexts.

    Abstract: In the present study, 102 chickpea germplasm showed wide range of variation for various characters evaluated during Rabi 2017-18 along with BG 372, Udai and Pant G 186 as checks varieties. The experiment was conducted in Augmented Block Design at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.). The observations were recorded on 11 quantitative characters viz., days to 50 per cent flowering, days to maturity, primary branches per plant, secondary branches per plant, plant height (cm), pods per plant, seeds per pod, biological yield per plant (g), seed yield per plant (g), harvest index (%) and 100-seed weight (g). After analyzing the data statistical study of each characters genotypes revealed a wide range of results Genotypes GJG 1416 followed by BG 256, GJG 1416, PhuleG0819, IPC 2011-141 and IPC 1014 produced higher seed yield per plant and these genotypes constituted the top significant group for these traits..On other hand genotypes PDG 84-16, IPC 1014, H06-6, GJG 1401, GJG 1403 and JG2016-44 for early maturity;; BG 256, GJG 1209, GJG 1401, GJG 1416 and JG 11 were identified for high number of pods per plant; GJG 1416, GJG 1001, BG 256, RS 2011-06 and BG 3027 were identified for bold seed size; IPC 1014, PhuleG0805 and IPC 2010-134 for harvest index were found promising which may be used as potential donors for the traits in chickpea improvement programme. Seed yield per plant exhibited positive and highly significant correlations with secondary branches per plant, pods per plant, seeds per pod, biological yield per plant, harvest index and 100-seed weight. The positive significant correlations of seed yield per plant were found with primary branches per plant and non-significant with plant height. It exhibited negative non-significant association with days to 50 per cent flowering and days to maturity.
