Abstract:
Maize productivity is relatively better than other major cereal crops but its current productivity is still far below than its potential productivity. The rate and time of N application are among the major abiotic factors limiting the productivity of the crop. Because of such gaps, the experiment was carried out to study the impact of soil and foliar nutrient management practices on soil fertility in sweet corn (Zea mays var. saccharata). The factors consisted of three level of nitrogen (F₁: 50% RDN, F₂: 75% RDN and F₃: 100% RDN) and two levels of split application (S₁: two splits with basal and 30 DAS, S₂: three splits with basal, 20 and 40 DAS) with and without foliar application of nitrogen (N₀: control and N₁: 2% urea at 50 DAS). The result showed that soil application of nutrient in different levels and splits gave significant effect on nitrogen availability in soil after harvest. Available nitrogen in soil after harvest was found significantly enhanced with application of 100% RDN (F₃) as well as application of N with three splits (at basal, 20 and 40 DAS) (S₂). Application of N in different splits reduced the losses of nitrogen which becomes available for longer period and increased its use efficiency and efficient uptake while foliar application increases immediate availability of nitrogen at later growth stage.
