Influence of Organic Nutrients on Growth and Yield of Summer Greengram (Vigna radiata)

Greengram ( Vigna radiata L. ), commonly called as mungbean is an important pulse crop grown mainly in Zaid and Kharif season in India. Organic farming is one of the sustainable farming practices that can overcome the harmful effects of chemical farming and provides quality production. A field experiment was conducted during Zaid, 2023 to study the “Effects of organic nutrients on growth and yield of summer Greengram (Vigna radiata L.)” at SHUATS Model Organic Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The experiment was laid out in a randomized block design with nine treatments replicated thrice. The treatment consisted of 3 different solid manures i.e. Farm Yard Manure, Vermicompost, Goat manure and 3 different liquid manures i.e. Fish Amino Acid, Panchagavya and Seaweed (Kappaphycus alvarezii) sap. The experimental field soil was sandy loam in texture, moderately basic in reaction (pH 7.8), available medium Organic Carbon (0.662 %) low in available nitrogen (249.5 kg/ha), and very high accessible phosphorus (38.7 kg/ha) and available potassium (240.8 kg/ha). The result showed that significantly higher growth parameters viz., plant height (42.09 cm), number of nodules (22.22/plant), dry weight (19.35g/plant) and yield attributes such as effective pod/plant (11.05), seed/pod (9.68), test weight (38.41 g), seed yield (1643.54 kg/ha) and stover yield (3023.55 kg/ha) were observed with application 5 t/ha FYM and foliar spray of 7.5 % K sap (T9). Highest net return (Rs. 100383.30/ha) and benefit cost ratio (1.84) was also recorded in the same treatment. This concludes that application of 5 t/ha FYM along with foliar spray of 7.5 % K sap at 15 and 30 DAS performed better in terms of yield and economic returns.
