Abstract: Studies of split application strategy of nitrogen on the economics of the kharif maize is needed to enhance the nitrogen use efficiency. The field experiment was conducted at Cotton Research Station, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. Dist. Parbhani during Kharif season of 2015 to evaluate the effect of split application of nitrogen on economics 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. Treatment T6 also recorded significantly the highest gross returns (51014 ₹ ha-1), net returns (30530 ₹ ha-1) and B:C (2.49) ratio as compare to other treatments.
