Present investigation was carried out at the research farm of Uttar Banga Krishi Viswavidyalaya located at Cooch Behar district of West Bengal during crop season of 2016-17 to find out the optimum timing and amount of nitrogenous fertilizer to lessen the losses of applied nitrogen through leaching in light texture soil, thereby improving efficiencies and productivity of summer maize. Experiment was laid out in randomized block design with six treatments and four replications. Treatments comprises of T1 : Control (no fertilizer), T2 : 90 kg N ha-1 at sowing + 30 kg N ha-1 at 35 DAS, T3 : 60kg N ha-1 at sowing + 60 kg N ha-1 at 35 DAS, T4 : 60 kg N ha-1 at sowing + 30 kg N ha-1 at 35 DAS + 30 kg N ha-1 at 55 DAS, T5 = 40 kg N ha-1 at sowing + 40 kg N ha-1 at 35 DAS + 40 kg N ha-1 at 55 DAS and T6 : 120 kg N ha-1 at sowing. Outcome of the experiment revealed that whenever nitrogen was applied in three equal splits (T5) producing 202 % and 24.19 % more grain yield over T1 and T6. The hi
Economics, Maize, Nitrogen and Use efficiencies
The findings indicates that application of 120 kg nitrogen in three equal splits along with 60 kg phosphorus and potassium ha-1 was found superior for improving the productivity and profitability of maize through maximizing efficiencies of applied nitrogen, thus it is recommended for the farmers of terai region having sandy loam soil.
