Abstract
The agronomic performance of two new improved rice varieties was evaluated under two levels of N application and spacings.
IR 36, a very early maturing rice variety outyielded C 168 a medium early maturing rice variety.
Plants spaced at 40cm x 5cm using one seedling per hill with rows oriented east-west, produced significantly higher yield, more panicles per square of land area but lower leaf area index at flowering than those spaced at 20cm x 20cm using two seedlings per hill.
The levels of nitrogen applied, i. e., 40 kg N/ha for low N rate and 80 kg N/ha for high N rate, did not affect significantly the yield, harvest index percentage of unfilled grains. However, higher rate of nitrogen promoted higher LAI values of both varieties. The LAI value of both varieties were significantly affected by variety x spacing interaction.
