Effect of Integrated Nutrient Management on Growth and Productivity of Wheat (Triticum aestivum L.) in Typic Ustochrepts Soils of Western U. P., India

A field experiment was conducted during Rabi seasons to determine the effect of different sources of nutrient on growth, yield and yield of wheat for improving crop productivity in western U.P. The experiment was laid out in Randomized Block Design (RBD) with three replications and the treatments assigned in this study are fourteen viz., Control T1, 100% Recommended NPK (150: 75: 60 kg ha-1) T2, 50% Recommended N + FYM @10t/ha T3, 50% Recommended N + 50% N through Vermicompost + Bio-stimulant-G@ 20kg/ha T4, 50% Recommended N + Bio-stimulant-G@ 20kg/ha T5, 75% Recommended N + 50% N through Vermicompost T6, 75% Recommended N + FYM @10t/ha + Bio-stimulant-G 20kg/ha T7, FYM @10t/ha + Bio-stimulants Toggle (Containing marine extracts) @ 2.9 l/ha T8, FYM @10t/ha + Bio-stimulant Voyagro (containing proline, glycine betaine and glutamic acid) @ 585 ml/ha T9, 100% Recommended N + FYM @10t/ha T10, FYM @10t/ha + NPK-bio-fertilizer + Urea @20 kg/ha T11, FYM @10t/ha + Bio-fertilizer mixture (A.chrococcum + AMF + B.circulans) + Bio-stimulant-L @ 625 ml/ha foliar spray each at 45 & 60 DAS T12, 100% Recommended N + FYM @10t/ha + Azatobacter T13, 50% Recommended N + FYM @10t/ha + 25% N through Vermicompost T14. Among the different treatments, the treatment T13 was observed significantly higher in growth characters, physiological parameters and yield parameters of the year compared to other treatments. T13 recorded 113.7, 93.6 and 151.5 plant height, number of tillers m-1row length and dry matter accumulation (g/m1) than T1 control with no nutrient application respectively. Crop fed with treatment T13 registered highest CGR 90 days till harvest (3.27 g m-2 area d-1) and RGR 90 days till harvest (0.0002 g g-1d-1). Treatment T7 recorded maximum NAR at 90DAS-at harvest stage (0.86 g m-2 leaf area day-1)), which was at par with treatment T9. Treatment T13 recorded significantly highest grain yield (47.5 Kg ha-1), straw yield (64.0 kg ha-1), biological yield (111.5 kg ha-1) and harvest index (42.6 %) while the lowest was recorded under control T1.
