A field experiment was conducted with the objective of assessing yield and quality of fodder cowpea by supplementing zinc through foliar nutrition in randomized block design with eight treatments and three replications. The treatments were T1 (100% RDF), T2 (75% RDF), T3 (T1 + zinc @ 0.25% as foliar spray at 20 DAS), T4 (T1 + boron @ 0.25% as foliar spray at 20 DAS), T5 (T1 + boron @ 0.125% + zinc @ 0.125% as foliar spray at 20 DAS), T6 (T2 + zinc @ 0.25% as foliar spray @ 20 DAS), T7 (T2 + boron @ 0.25% as foliar spray @ 20 DAS) and T8 (T2 + boron @ 0.125% + zinc @ 0.125% as foliar spray at 20 DAS). The results revealed that for augmented yield and quality of fodder cowpea in sandy loam soils has to be supplied with FYM @ 10 t/ha as basal dose along with N, P2O5 and K2O @ 25:60:30 kg/ha along with foliar application of zinc sulphate heptahydrate @ 0.25 percent at 20 days after sowing.
