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( days after sowing )(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 results revealed that the growth attributes, yield contributing characters, grain yield, and fodder yield of maize are higher in treatment T6 (33%N at sowing + 33%N at 30 DAS + 33% at 60 DAS).
