Integrated nutrient management in greengram [Vignaradiata (L.) Wilczek] cultivars

Abstract

A field experiment was conducted during kharif, 2014 at Agronomy Instructional Farm, C.P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, to study the “yield attributes and yield ofgreengram [Vignaradiata (L) Wilczek] cultivars as influenced by integrated nutrient management.” Fourteen treatment combinations comprising of two varieties of greengram viz., Meha(V1) and GM 4(V2) and seven treatments of integrated nutrient management viz., 100% RDF(N1), 75% RDF + 2 t FYM/ha(N2), 75% RDF+Rhizobium+PSB, 75% RDF + 2 t FYM/ha + Rhizobium + PSB, 50% RDF+ 4 t FYM/ha, 50% RDF + Rhizobium + PSB and 50% RDF + 4 t FYM/ha + Rhizobium + PSB were evaluated. The results revealed that greengram cultivar Meha performed better by recording 17.3 and 15.3 per cent higher seedand stover yield, respectively over GM 4. Variety GM 4 registered maximum nitrogen content while phosphorus content and uptake of N & P were recorded significantly higher with variety Meha. Combined application of 75% RDF from urea+2 t FYM/ha + Rhizobium + PSB recorded higher values for number of plant height, number of branches per plant, pods per plant, fresh and dry weight of root nodules, number of seeds per pod, pod length, number of seed per pod, 1000-seeds weight which resulted higherseed (746 kg/ha) and stover (1806) yield over other combination and sole application of organic and inorganic source of nitrogen. Maximum content and uptake of N and P were registered with combined application of 75% RDF from urea+2 t FYM/ha + Rhizobium + PSB.
