Abstract:
The experiment was conducted at Student Instructional Farm, C. S. Azad University of Agriculture and Technology, Kanpur during kharif and rabi seasons of 2018-19 and 2019-20. There were eight treatments combinations i.e., T₁: LCC 3, T₂: LCC 4, T₃: LCC 5, T₄: CCM 30, T₅: CCM 35, T₆: CCM 40, T₇:100% RDN as 3 splits (2:1:1) at basal, knee height and tasseling stage and T₈: 75% RDN as 3 equal splits at basal, knee height and tasseling stage. The experiment was laid out in RBD with four replication on silt loam soil with low organic carbon (0.43%) available nitrogen (161.43 kg ha^-1) and available phosphorus (14.71 kg ha^-1) while medium in potassium (240.33 kg ha^-1), respectively. Numerous treatments significantly influenced the yield of maize during both the years as well as in pooled analysis. Among all the treatment tested, treatment T₃ (LCC 5, i.e. application of 30 kg N ha^-1 based on LCC critical value 5) recorded significantly higher yield during the years 2019, 2020 and on pooled basis. Treatment T₃ (LCC 5, i.e. application of 30 kg N ha^-1 based on LCC critical value 5) found to be superior with respect to yield over rest of the treatments. The yield components like grain protein content, N, P, K content as well as N, P, K uptake in grain and stover were maximum with the treatment T₃ (LCC 5, i.e. application of 30 kg N ha^-1 based on LCC critical value 5) and found to be greater over other treatments during the years 2019, 2020 and on pooled basis.
