Yield reponse of Kharif maize for split application of nitrogen

Abstract

The field experiment was conducted at Cotton Research Station, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. Dist. Parbhani during Kharif season of 2015 to study the “Effect of split application of nitrogen on growth and yield of kharif maize (Zea mays. L)”. The experiment was laid out in randomized block design with three replications. The treatment details of experiment factor comprised seven split application of nitrogen treatments viz.,100% Nitrogen at sowing (T1), 75%N at sowing +25%N at 30 DAS (T2), 50%N at sowing +50% N at 30 DAS (T3), 25% N at sowing +75%N at 30 DAS (T4), 25%N at sowing +50% N at 30 DAS + 25% at 60 DAS (T5), 33%N at sowing + 33%N at 30 DAS + 33% at 60 DAS (T6) and 25% N at sowing + 25%N at 30 DAS+25% at 60DAS + 25% N at 60 DAS (T7). The split application of nitrogen T6 (33%N at sowing + 33%N at 30 DAS +33% at 60 DAS) produced significantly higher grain (2950 kg ha-1), stover (6332 kg ha-1) and biological (9282 kg ha-1) yields as compared to others.
