Abstract:
A field experiment was conducted to study the scope of customized fertilizer for increasing the productivity of wheat system in U.P. during Rabi season of the year 2016-17 at Farmer field in the village of Pero Saraiya (Dehli Bazar) in the District of Sultanpur. The results revealed that maximum uptake of N (108.12 kgha^-1), P (29.02 kgha^-1), K (116.24 kgha^-1), S (70.10kgha^-1), Zn (207.10gha^-1) and B (58.15gha^-1) observed in treatment having Soil test based recommendation (T₃) followed by T₄ -Indo-Gulf Customized Fertilizer, similarly the maximum availability of P (17.10 kgha^-1), S (11.80 kgha^-1), Zn (0.51 ppm) and B (0.45 ppm) and maximum decline in soil pH (7.57), EC (0.26 dSm^-1) with maximum buildup of organic carbon (0.34gkg^-1) content in soil recorded in treatment T₃ -Soil test based recommendation, while the maximum available N (176.28 kgha^-1) and K (250.10kgha^-1) were observed under treatment T₂ (RDF). The minimum uptake and availability of N, P, K, S, Zn, B and minimum decline in soil pH and EC were recorded in the treatment T₁ (control).
