The field experiment was conducted during Zaid, season 2024 to study the “Evaluating the efficacy of Organic nutrient sources on growth and yield of Greengram (Vigna radiata L.)’ at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, U.P. The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice. The treatment consisted of different levels of solid manures Ghanajeevamruth (500kg/ha), Neem cake (400kg/ha), Mustard Cake (500kg/ha) and liquid organic manure Shasyagavya (5%, 10%, and 15%). The experimental field soil was sandy loam in texture, moderately basic in reaction (pH 7.3), available medium organic Carbon (0.764 %) low in available nitrogen (272.4 kg/ha), and very high accessible phosphorus (34.4kg/ha) and available potassium (252.6 kg/ha). The result showed that significantly higher growth parameters viz., plant height (39.57cm), number of nodules (7.47/plant),number of branches(11.53/plant),dry weight (8.30g/plant) and yield attributes such as effective pod/plant (8.47), seed/pod (10.47), test weight (39.00 g), seed yield (1170.02kg/ha) and stover yield (2216.03kg/ha) were observed with application Mustard Cake 500kg/ha and foliar spray of Shasyagavya 5% in treatment number 7. Highest gross return (Rs.97726.40/ha), net return (Rs.72576.40/ha) and benefit cost ratio (2.89) was also recorded in the same treatment.
