A field experiment entitled, “Performance of maize (Zea mays L.) hybrids under different planting methods and nitrogen levels” was conducted at Agronomy research farm, CCS Haryana Agricultural University, Hisar during kharif 2013 and 2014. The experiment consisted of four planting techniques viz. Raised Bed System (RBS), Flat Sowing with Zero Tillage (FSZT), Flat Sowing with Minimum Tillage (FSMT) and Flat Sowing with Conventional Tillage (FSCT) in main plots and two maize hybrids viz. HQPM-1 and HQPM-5 and three nitrogen levels viz. 120, 150 and 180 kg N ha-1 in sub plots with combination, were tested in split plot design with three replications. Results obtained from this experiment indicated that the highest nutrient uptake by maize was recorded with FSZT as compared to RBS, FSMT and FSMT. The highest nitrogen uptake by maize (91.50 kg ha-1 by grain and 59.01 by stover during 2013 and 86.28 kg ha-1 by grain and 53.28 kg ha-1 by stover during 2014 crop seasons, respectively) was recorded with FSZT planted maize. Likewise, between the maize hybrids HQPM-5 recorded significantly higher nitrogen uptake over HQPM-1 hybrid during both the crop seasons. Among the nitrogen levels N uptake was found to enhance with successive levels of nitrogen from 120 kg N ha-1 to 180 kg N ha-1 during 2013 and 2014 crop seasons. Effects of different treatments on uptake of phosphorus and potassium by maize grain and stover were almost similar to nitrogen uptake. Application of nitrogen increased significantly NPK uptake.
