Effect of Organic Manures and Chemical Fertilizers on Growth and Yield of Green Gram (Vigna radiata L.)

Abstract

A field experiment was conducted at experimental farm, Department of Agronomy, Faculty of Agriculture and Veterinary Sciences, Mewar University Gangrar, Chittorgarh (Rajasthan) during Rabi season of 2023-24 to effect of organic manures and chemical fertilizers on growth and yield of green gram, variety “SML-832‟ was used in this study. The required quantities of fertilizers as per treatments were applied. The experiment was laid out in randomized block design with three replications consisting of ten treatments. The data recorded maximum growth parameters like, plant height (51.45 cm), number of branches per plant (4.08) and yield parameters like, number of pods per plant (20.58, number of seeds per pod (8.65), test weight (38.92 g), grain yield (1106.45 kg/ha), straw yield (2583.85 kg/ha) and maximum net return (48100 Rs/ha) and B:C ratio (1.58) was recorded with T9-75% Vermicompost @ 1.25 t per ha. The minimum growth and yield obtained with control treatment. Therefore, concluded that impact of different organic manures and chemical fertilizers on the growth and yield of the green gram. Among different T9-75% RDF + Vermicompost @ 1.25 t per ha registered the maximum production with higher net return.  So, it was concluded that the treatment 75% RDF + Vermicompost @ 1.25 t per ha superior among all treatments.
