Impact of Different Nutrient Management Practices on the Nutrient Dynamics of Wheat Crop in Western Uttar Pradesh, India

The field experiment was conduct at Crop Research Center of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, (U.P.) during winter season of 2021-22 and 2022.The Experiment was laid out in Randomized Block Design with three replication and seven treatments i.e. T1: Control, T2: 100% NPK (150, 75, 60), T3: 75% NPK+ FYM @ 7.5 t ha-1, T4: 75% NPK + Vermicompost @ 2.5 t ha-1, T5: 100% NPK + Paddy straw @ 2.0 t ha-1, T6: 100% NPK + Paddy straw @ 2.0 t ha-1 + Pusa Decomposer @ 20 lit. ha-1, T7: 100% NPK + Paddy straw @ 2.0 t ha-1 + Vermicompost @ 1.0 t ha-1. Various growth and yield characteristics were observed and statistically analyzed. The absorption of wheat grain and straw as well as the nitrogen, phosphorus, and potassium content were greatly enhanced by the addition of 100% NPK + Paddy straw @ 2.0 t/ ha-1 + Vermicompost @ 1.0 t/ ha-1 over both years. The increased fertilizer levels resulted in a significant increase in the nutritional content and uptake in plants. The nutrient content and uptake in wheat grain and straw increased significantly over control plots when 100% NPK + Paddy straw @ 2.0 t/ha + Vermicompost @ 1.0 t/ha was applied, but it was on par with 100% NPK + Paddy straw @ 2.0 t/ha + Pusa Decomposer @ 20 lit./ha.
