Effect of Plant Spacing and Organic Nutrient Management on Growth and Yield Attributes of Green Gram (Vigna radiata L.)

Abstract

The field experiment was conducted during Zaid season of 2021 at the CRF, Department of Agronomy, SHUATS, Prayagraj (U.P.). The soil of the experiment plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.2), low in organic carbon (0.72%), available N (278.48 kg/ha), available P (27.80 kg/ha) and available K (233.24 kg/ha). The treatments included three spacing’s (20 cm × 10 cm, 30 cm × 10 cm and 40 cm × 10 cm), as well as three organic nutrient managements (4 t/ha Vermicompost + 10% Vermiwash + 10% Jeevamruth at 20 DAS, 5 t/ha Vermicompost + 12% Vermiwash + 5 kg/ha FYM + 12% Jeevamruth at 40 DAS and 6 t/ha Vermicompost + 14% Vermiwash + 6 kg/ha FYM), respectively. The experiment was laid out in a randomized block design with nine treatments combinations and the treatment combinations were replicated thrice. The results obtained showed that growth parameters such as plant height (63.41 cm), number of branches (6.60/plant) and plant dry weight (13.38 g/plant) were significantly higher with the application of 30 cm × 10 cm spacing along with + 5 t/ha VC + 12% VW + 5 kg/ha FYM + 12% J at 40 DAS. While yield parameters such as pods (25.52/plant) were the highest in 40 cm × 10 cm + 5 t/ha VC + 12% VW + 5 kg/ha FYM + 12% J at 40 DAS. Whereas, seed yield (1,869.82 kg/ha), haulm yield (3,888.33 kg/ha), harvest index (33.84%), gross returns (INR 2, 28,266.33/ha), net returns (INR 1, 64,206.33/ha) and benefit: cost ratio (2.89) were recorded maximum in the treatment combination of 20 cm × 10 cm + 5 t/ha VC + 12% VW + 5 kg/ha FYM + 12% J at 40 DAS.
