An experiment consisting of four entries(E1-TNFC-0926, E2-Bundel lobia-1, E3-UPC-5286 and E4-UPC-622) and three single super phosphate levels (F1-190, F2-375 and F3-560 kg ha-1 SSP) was laid out in randomized block design in factorial mode to find out the response of ‘‘Studies on effect of entries and different doses of single super phosphate on growth, forage yield and economics of cowpea (Vigna Unguiculata L.)’’. The maximum growth attributes viz., plant height, number of branches plant-1, dry matter production and yield (Green forage yield 175.91 and dry matter yield 27.27q ha-1) were recorded with application of 560 kg SSP ha-1(F3)which was significantly superior over F1 and being statistically at par with application of 375 kg SSP ha-1 (F2). Among the entries maximum growth attributes viz., plant height, number of branches plant-1, dry matter production and yield (Green forage yield 170 q ha-1 and dry matter yield 22.67 q ha-1) were recorded with UPC-5286 (E3) entry which was significantly superior over E1 and E2 and being statistically at par with E4. The maximum gross income was calculated with E3F3: 28065 and net income with E3F2: 13289. However, highest benefit cost ratio (0.84) was obtained with treatment combinations E3F2: UPC- 5286+ 375kg SSP ha-1.

Thus, the recommendation of F2 (375 kg SSP ha-1) and E3 (UPC-5286) be made to the farmers of eastern (U.P.) for successful cultivation of forage crop cowpea in kharif season.
