Abstract:
To know the effect of time of sowing, nitrogen, and zinc management on the wheat crop, an experiment was carried out at the research farm of the Institute of Agricultural Sciences, BHU, Varanasi during the rabi seasons of 2018-19 and 2019-20. The treatments were arranged in a split-plot design involving three replications. The main plot was constituted of two factors i.e., Time of sowing and Nitrogen management. The subplot had one factor i.e., Zinc management. Time of sowing had two levels i.e., D₁: sowing in the second fortnight of November and D₂: sowing in the first fortnight of December. Nitrogen management had also two levels i.e., N₁: 150 kg ha^-1 Nitrogen [75 kg basal+37.5 kg at Z20 (main shoot only) +37.5 kg at Z37 (flag leaf visible)] and N₂:150 kg ha^-1 Nitrogen [70 kg basal+35.4 kg at Z20 (main shoot only) +35.4 kg at Z37 (flag leaf visible) + 9.2 kg as 2% urea application at Z60 (beginning of anthesis stage)]. The subplot zinc consisted of four levels i.e., Z₁: 0 kg ha^-1 Zinc (No Zinc), Z₂: 5 kg ha^-1 Zinc as basal, Z₃: 1.7 kg ha^-1 Zinc as basal + 0.50% ZnSO_4, H₂O spray Z31 (Stem elongation) + 0.50% at Z75 (Milking), Z₄: 1.7 kg ha^-1 Zinc as basal + 0.50% ZnSO₄, H₂O spray at Z60 (Anthesis) + 0.50% at Z85 (Dough stage). According to the results of the afore mentioned comprehensive study, wheat should be planted in the second fortnight of November with 150 kg ha^-1 Nitrogen [75 kg basal + 37.5 kg at Z20 (only the main shoot) + 37.5 kg at Z37 (flag leaf visible)] and 1.7 kg ha^-1 Zinc as basal + 0.50% ZnSO₄, H₂O spray at Z31 (stem elongation) + 0.50% at Z75 (milking) (Z3).
