ABSTRACT
A field experiment was carried out during summer season of the year 2012 at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) to study the effect of different sources and levels of phosphorus on cowpea. The treatments comprising of four sources of phosphorus [DAP (18-46-00), SSP (00-16-00-13), Narmada Phos (20-20-00) and IPL (20-20-00)] and three levels of phosphorus [20, 40 and 60 kg P2O5/ha] with one control P0. The experiment was laid out in Factorial RBD with four replications. Higher values of growth characters and dry gotar yield were recorded under treatment S1 (DAP), while yield attributes and seed yield were recorded higher under treatment S2 (SSP). Each successive increase in the level of P from 20 to 60 kg P2O5/ha significantly increased the growth characters, yield attributes, seed and dry gotar yield.
Key words :
Cowpea, Growth & yield attributes, Phosphorus levels, Sources of phosphorus.
