Yield enhancement in greengram [Vigna radiata (L) Wilczek] through integrated nutrient management approaches

Abstract

A field experiment was conducted at the Agricultural Experimental Farm of Calcutta University, Baruipur, 24 Parganas (South), West Bengal, during the summer of 2018 to assess the yield parameters of greengram [Vigna radiata (L) Wilczek] through integrated nutrient management strategies. The experiment was laid out in a randomized block design replicated thrice with 7 treatments. The results revealed that in T6, the integrated application of 100% RDF + FYM @ 10t/ha + Rhizobium inoculation @ 25 g/kg of seed recorded significantly higher yield parameters over the other treatments. T6 also recorded a higher seed yield of 1,096.93 Kg/ha as compared to other treatments. The number of pods per plant ranged from 20.19 to 29.04. Pod length showed considerable improvement from 7.38 cm in T1(Control) to 9.13 cm in T6, and test weight increased from 3.13 g under the control to 3.87 g in the highest performing treatment. Hence, the enhancement of crop growth and final grain production is closely linked to proper nutrient management, and INM achieves this through the synergistic use of fertilizers, organic manures, and biofertilizers.
