A field experiment was conducted during two consecutive Kharif (2016 and 2017) at Students’ Instructional Farm, Department of Agronomy, C. S. Azad University of Agriculture and Technology, Kanpur. The present study consisted of five land configurations as main plot treatments viz., broadcasting, flat sowing, flat followed by earthing, narrow bed and furrow and broad bed and furrow and four nutrient management practices as sub plot treatments viz., basal dose of NPK + top dressing of N in two splits, basal dose of NPK + foliar spray of N in two splits, basal dose of NPK + N through LCC and basal doses of P and K + N through LCC only, and was laid out in split plot design and replicated thrice. The soil of experimental site was sandy loam in texture, low in organic carbon and available nitrogen, medium in available phosphorous and potassium. The hybrid variety (DKC9144) was sown as per treatment in plant geometry (50×25cm) maintained by thinning. The present investigation revealed that the seed sown in broad bed and furrow accumulated significantly highest nitrogen (grain 1.42% and stover 0.60%), phosphorus (grain 0.33% and stover 0.17%) and potassium (grain 0.38% and stover 1.10%) contents and uptake of these nutrients was also maximum in the same treatment i.e., nitrogen (grain 98.3 and stover 76.5 kg ha-1), phosphorus (grain 42.0 and stover 21.4 kg ha-1) and potassium (grain 26.5 and stover 140.8 kg ha-1) in pooled analysis. Hybrid maize accumulation significantly higher through basal dose of NPK + N through LCC nutrient content when fertilizer nitrogen (grain 1.42% and stover 0.60%), phosphorus (grain 0.33% and stover 0.17%) and potassium (grain 0.38% and stover 1.10%) there by uptake in grain and stover was also higher nitrogen (grain 95.9 and stover 75.3 kg ha-1), phosphorus (grain 41.3 and stover 21.1 kg ha-1) and potassium (grain 25.8 and stover 138.4 kg ha-1) in pooled analysis. Maximum improvement in available status of nitrogen (305.0 kg ha-1), phosphorous (18.9 kg ha-1) and potassium (244.0 kg ha-1) was recorded with broad bed and furrow method followed by narrow bed and furrow system and minimum at broad casting systems over its initial values. In nutrient management system highest increase in available status of N, P and K was recorded in basal dose of NPK + N through LCC followed by basal dose of P and K + N through LCC only over its initial values.
