Effect of Phosphorus and Zinc Nutrition on Fodder Yield and economics of Cowpea (Vigna unguiculata L. walp)

The area test becomes done for the length of Zaid 2021 at Crop concentrates on Farm, part of Agronomy, SHUATS, Prayagraj, (U.P). On the surface, the test plot's dirt was sandy topsoil, almost impartial in soil response (pH 7.2), low in natural carbon (0.536%), accessible N (163.42 Kilograms per hectare), to be had P (21. 96 Kilograms per hectare), to be had k (256. 48 Kilograms per hectare). The treatments incorporate three phases of phosphorus (50 Kilograms per ha, 60 Kilograms per ha, and 70 Kilograms per ha) and zinc (15 Kilograms per hectare, 20 Kilograms per hectare, and 25 Kilograms per hectare). The test becomes spread out in a Randomized Block format that incorporates nine treatments and is repeated threefold. The impacts found that the greatest green fodder yield (365.13 q per ha) and dry matter yield (74. 14 q per ha) were recorded with a product of 70 Kilograms per ha P2O5 + 25 Kilograms per ha ZnSO4. be that as it may, the most over the high gross returns (91282.07 INR per ha), net returns (61277.50 INR per ha), and benefit cost ratio (2.04) were gotten highest inside the treatment mix of 70 Kilograms per ha P2O5 + 25 Kilograms per ha ZnSO4.
