Effect of organic nutrient sources on growth, yield, quality and economics of green gram (Vigna radiata L.) under organic farming

Abstract

A study was conducted at ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari during the rabi season of 2020 to examine the impact of various organic nutrient sources on the growth, yield, quality and economic aspects of green gram cultivation in a certified organic farm. Among the individual treatments 100% RDN through vermicompost + EBPS 1% (T6) recorded higher plant height at the time of harvest (63.7 cm), number of pods per plant (26.3), grain yield (11.2 q/ha), stover yield (22.7 q/ha) and highest crude protein yield (203.9 kg/ha) among all the treatments. Whereas, length of the pod, Number of seeds per pod, 1000 grain weight and Harvest index were not significantly influenced by different treatments. While looking to economics, 100% RDN through vermicompost + EBPS 1% (T6) realized higher gross (105704 ₹/ha) and net returns (64001 ₹/ha) and 100% RDN through NADEP compost + EBPS 1% (T2) recorded higher benefit-cost ratio (1.62) among all the treatments.
