Author(s): K. C. GUPTA AND R. SAXENA
Abstract: Field experiments was conducted for three consecutive kharif seasons of 2011, 2012 and 2013 at Rajasthan Agricultural Research Institute, Durgapura, Jaipur to study the effect of resource management in cowpea for yield maximization under rainfed conditions. Results of three years pooled data revealed that foliar application of urea either @ 1% or @ 2% and mulching @ 3 t ha-1 at 25-30 DAS of crop significantly increased yield attributes (pods plant-1, seeds pod-1 and seed index) and seed yield of cowpea. Foliar application of 2% urea recorded maximum values of yield attributes, seed yield, net returns ( ha-1) and B:C ratio. The significant increase in pods plant-1, seeds pod-1 and seed index due to foliar application of 2% urea were 7.64 and 16.34, 4.38 and 9.30 and 5.23 and 6.23 per cent respectively over normal planting and control. Further, the maximum value of pooled grain yield (9.26 q ha-1), net returns ( 21892 ha-1) and B:C ratio (1.77) were recorded under foliar application of 2% urea while the least were observed under control (5.47 q ha-1, 9299 ha-1 and 0.85).
