Abstract:
The experiment was conducted on cotton research station of Vasantrao Marathwada Agricultural University, Parbhani during kharif season 2015 to study the Effect of split application of nitrogen on growth and yield of kharif maize. The test crops were raised on field during kharif-2015. The experiment was laid out in randomized block design (RBD). The treatment details of experiment consisted of 7 treatment: (1) T1 –100% Nitrogen at sowing, (2) T2 –75% N at sowing +25%N at 30 DAS, (3) T3 – 50% N at sowing +50% N at 30 DAS, (4) T4 – 25% N at sowing +75% N at 30 DAS, (5) T5 –25%N at sowing +50% N at 30 DAS + 25% at 60 DAS, (6) T6 – 33%N at sowing + 33%N at 30 DAS +33% at 60 DAS and (7) T7 – 25% N at sowing + 25%N at 30 DAS+25% at 60DAS +25% N at 75 DAS The maximum increase in N,P and K status increased the soil nutrient status after harvesting. Maximum nutrient status found in treatment where 100% nitrogen applied at the time of sowing which is not good for soil health. However, the treatment found the significantly superior than other treatments where 33% N at sowing + 33% N at 30 DAS + 33% at 60 DAS applied.
