Abstract:
The experiment was conducted at Zonal Agricultural Research Station (ZARS), Gandhi Krishi Vigyan Kendra (GKVK), University of Agricultural Sciences (UAS), Bangalore. To evaluate the of foliar nutrition on growth and yield of cowpea under changing climate. Experiment consists of application of three foliar nutrients and their concentrations (DAP, Pulse magic and Ampoxcilin) at 40 DAS the experiment consist of thirteen treatments replicated thrice in RCBD. The yield attributes were significantly varied with foliar application of 75% RDF + 2% DAP + 2% Pulse magic + 0.2% Ampoxcilin. Higher number of pod plant^-1 (27.8), Pod length (18.1 cm) and number of seeds pod^-1 (17.5) were recorded. Whereas, lower number of pod plant^-1 (20.6), pod length (14.7 cm) and number of seeds pod^-1 (13.5) were recorded with 75% RDF + Water spray. Higher seed yield, net returns and BC ratio (1357 kg ha^-1, Rs. 60534 ha^-1 and 2.91, respectively) recorded with application of 75% RDF + 2% DAP + 2% Pulse magic + 0.2% Ampoxcilin and lower seed yield, net returns and BC ratio (Rs. 24556 ha^-1 and 1.71, respectively) were obtained with 100% RDF + Water spray.
