ABSTRACT

An experiment consisting of four phosphorus levels (0, 40, 60 and 80 kg P2O5/ha) and five zinc levels (0, 10, 20, 30 and 40 kg/ha ZnSO4) was laid out in factorial RBD to find out the economics of fodder cowpea (Vigna unguiculata (L.)Walp) production. Application of 60 kg/ha phosphorus recorded maximum net income (Rs. 28187.33) and B: C ratio (2.12) were recorded with application of 60 kg P2O5/ha. Highest net income (Rs. 26333.75) was recorded with 30 kg ZnSO4/ha and B: C ratio (2.06) were recorded with application of with 20 kg ZnSO4/ha. At mean physical (78.20 kg P2O5/ha) and economic (69.78 kg P2O5/ha) optimum dose of phosphorus the responses were 282.65 and 280.84 q/ha green fodder, respectively. At mean physical (30.20 kg ZnSO4/ha) and economic (28.06 kg ZnSO4/ha) optimum dose of ZnSO4 the responses were 272.01 and 264.55 q/ha green fodder, respectively.
