Abstract:
Field experiment was conducted during Rabi season 2021-22 at Research Farm Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, SHUATS, Prayagraj. To study the effects and uses of Organic Manure and Micro-Macro nutrients on wheat there were 9 treatments combinations replicated thrice in 3₂ factorial randomized block design with three levels of NPK @ 0,50 and 100% ha^-1, three level of FYM @ 0, 50 and 100% ha^-1 and three levels of Zinc @ 0,50 and 100%ha^-1 respectively. The results of treatment T₉ [100% (NPK + Zn) + @100%FYM] has impact on soil health, growth and yield of wheat. The observed results after crop harvest were slightly decrease in Bulk density.1.335 Mg m^-3 (0-15cm) and 1.334 Mg m^-3 (15-30cm), there is a significant increase in pH 7.29 (0-15cm) and 7.28 (15-30cm), EC 0.329 dS m^-1(0-15cm) and 0.328 dS m^-1 (15-30cm), Particle density 2.427. Mg m^{- 3} (0-15cm) and 2.429 Mg m^-3 (15-30cm), OC 0.79% (0-15cm) and 0.72% (15- 30cm), Pore space 49.12(0-15cm) and 49.01 (15-30cm), Water holding capacity 47.25% (0-15cm) and 47.20% (15- 30cm), Available Nitrogen 262.18kg (0-15cm) ha^-1 and 260.89kg ha^-1 (15- 30cm), Phosphorous 20.32kg ha^-1 (0-15cm) and 18.88 kg ha^-1 (15-30cm), Potassium 146.63kg ha^-1 (0-15cm) and 142.36 kg ha^-1 (15-30cm), Available Zn 0.65 mg kg^-1 (0-15cm) and 0.66mg kg^-1(15-30cm), regarding to plant growth T₉ [@100% (NPK+Zn)+@100%FYM) gave the best results with respect to plant height (100 cm), number of tillers plant^-1 (5) No. of grains plant^-1 (60) yield (20.37 q ha^-1). On the basis of result obtained during present investigation that the application of T₉ [@100% (NPK+Zn)+@100%FYM] exhibits the significant impact on Soil properties, growth and yield of wheat. The treatment T₉ combination gave the maximum cost benefit ratio of 2.84.
