| Abstract: |
Hybrid maize (RML-4/NML-2) was evaluated for its grain production by the application of different levels of nitrogen (60, 120 and 180 kg N ha-1) at varying plant densities (55555, 66666 and 83383 plants/ha) along with 60 kg P2O5 and 40 kg K2O ha-1 in the acidic soil (pH 5.3) of National Maize Research Program, Rampur, Chitwan during the years of 2008/09 and 2009/10. Factorial randomized complete block design(RCBD) with three replications was employed in the experiment. The crop was planted at the plot size of 18 m2 (3.6 × 5 m). The crop was planted in the month of September and harvested in February. The result indicated a sharp response of nitrogen application to this crop whereas the effect of density was observed to be non-significant. Two years mean yield results showed that highest grain yield (11.10 t ha-1) was recorded when the crop was supplied with 180 kg nitrogen and with 83383 plants ha-1 followed by the crop supplied with 120 kg N ha-1 and 66,666 plant population (10.69 t ha-1). It is inferred that application of high dose of N (180 kg N ha-1) could help increase hybrid maize grain production in acidic soils.
