Abstract:
The experiment was carried out at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during Rabi season of 2017-18 and 2018-19 to study the “Effect of different levels, splitting and foliar feeding of NPK fertilizer on growth and yield of wheat (Triticum aestivum L.)”. The soil of experimental field was clayey in texture (Vertisols) locally known as Kanhar. The experiments were laid out in randomized block design with three replication, 12 treatments viz. T₁- 50% RDF (50% of N as basal + 25% at CRI + 25% late jointing stage), T₂-100% RDF (50% of N as basal + 25% at CRI + 25% late jointing stage), T₃- 150% RDF (50% of N as basal + 25% at CRI + 25% late jointing stage), T₄-50% RDF (25% of N as basal + 25% at CRI + 25% tillering stage + 25% late jointing stage), T₅-100% RDF (25% of N as basal + 25% at CRI + 25% tillering stage + 25% late jointing stage), T₆-150% RDF (25% of N as basal + 25% at CRI + 25% tillering stage + 25% late jointing stage), T₇-T₄+ foliar spray of NPK (19:19:19) @ 5g l^-1 of water at 5 DA late jointing stage, T₈-T₅+ foliar spray of NPK (19:19:19) @ 5g l^-1 of water at 5 DA late jointing stage, T₉- T₆ + foliar spray of NPK (19:19:19) @ 5g l^-1 of water at 5 DA late jointing stage, T₁₀-T₄ + foliar spray of NPK (19:19:19) @ 5g l^-1 of water at 5 DA tillering and 5 DA late jointing stage, T₁₁-T₅+ foliar spray of NPK (19:19:19) @ 5g l^-1 of water at 5 DA tillering and 5 DA late jointing stage, T₁₂-T₆+ foliar spray of NPK (19:19:19) @ 5g l^-1 of water at 5 DA tillering and 5 DA late jointing stage were studied the results revealed that all growth parameters and yield viz., plant height, number of tillers m^-2, number of leaves m^-2, leaf area, leaf area index, dry matter accumulation m^-2, crop growth rate, relative growth rate and SPAD value, grain yield (39.87 and 40.87 q ha^-1), straw yield and harvest index by the crop were significantly highest under the treatments T₁₂: T₆+ foliar spray of NPK (19:19:19) @ 5g l^-1 of water at 5 DA tillering and 5 DA late jointing stage as compared to other but it was found at par with T₉, T₆, T₃, and T₈ during 2017-18 and 2018-19.
