Abstract:
A field experiment was conducted during kharif 2022 at ICAR-KVK, Kalaburagi to study the Nutrient management with Nano-DAP in pigeonpea. There were eight treatments consisting of different doses of RDF (two treatments with 50% RDF, two with 75% RDF, three with 100% RDF and one absolute control) with different doses of Nano-DAP sprayed (2 and 4 ml L^-1) at 45 & 60 DAS. Results revealed that application of 100% RDF as basal and Nano-DAP foliar spray @ 4 ml L^-1 at 45 and 60 DAS has produced significantly higher plant (213.6 cm) at harvest and higher number of branches per plant (34.7) at harvest also higher dry matter production (151.1g plant^-1) at harvest. It has resulted in enhanced number of pods per plant (194), test weight (11.85 g) and seed yield (1477 Kg/ha) and stalk yield (4619 Kg/ha) of pigeonpea also enhanced by application of Nano-DAP.
