EFFECT OF NUMBER OF SEEDLING HILL-1 AND NITROGEN LEVEL ON GROWTH AND YIELD OF BRRI dhan32 (Pages : 1 - 7)

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during, T. aman season 2002, to investigate the effect of number of seedling hill -1 and nitrogen level on growth and yield component of BRRI dhan32.The treatments were the variation numbers of seedling hill -1 viz., 1, 2, 3 and 4 seedling hill -1 and four levels of nitrogen viz; 0, 60, 80 and 100 kg N ha- 1 . Number of seedlings hill -1 significantly influenced growth and yield components except 1000-grain weight. It was found that the highest number of grains panicle-1 (100.92) and grain yield (5.37 t ha-1 ) were resulted from transplanting of 3 seedlings hill -1 and the lowest grain yield (4.38 t ha-1 ) was obtain from the transplanting of 1 seedling hill -1 . The highest straw yield (7.02 t ha-1 ) was obtain from the transplanting of 4 seedlings hill -1 and the lowest one (5.64 t ha-1 ) from the transplanting of 1 seedling hill -1 . Nitrogen level significantly influenced growth and yield components. The maximum grains panicle-1 (100.80) and highest grain yield (5.34 t ha-1 ) were obtained with 80 kg N ha-1 . The highest straw yield (6.98 t ha-1 ) was obtained at the highest nitrogen level (100 kg N ha-1 ). Result showed that 3 seedlings hill -1 and 80 kg N ha-1 was optimum to produced maximum yield of BRRI dhan32. Download
