ABSTRACT
A field experimental was conducted at the farm of Bangladesh Institute of Nuclear Agriculture (BINA) during July to November 1999. The objective was to see the effect of four levels of seedling hill ha-1 viz., 1, 2, 3 and 4 and two forms of nitrogen fertilizer-urea and USG on growth, yield and yield components of transplant aman rice cv. BINA Dhan4. The experiment was laid out in a split-plot design with three replications. The plots were fertilized @ 15, 40, 10, 1 kg ha ha-1 of PKSZn, respectively one day before transplanting. Urea was top dressed @ 80 kg ha ha-1 in three equal splits at 10, 30 and 50 DAT. The USG was placed at 5-8 cm depth at 10 DAT @ 2 granules in the center of four hills in alternate rows to supply 80 kg N ha ha-1 . Thirty-five day-old seedlings were transplanted on 19 August 1999. Results of mean effect of number of seedling hill ha-1 on growth parameters showed that plant length (141.31 cm) at 91 DAT and total tillers (13.06 hill ha-1 ) at 30 DAT were maximum with 1 and 4 seedlings hill ha-1 , respectively. The LAI of 4 seedlings hill ha-1 treatment had the highest value (5.22) at 63 DAT. Total dry matter (46.82 g hill ha-1 ) was the maximum at 91 DAT when the crop was transplanted at 4 seedlings hill ha-1 . The mean effects of forms of nitrogen fertilizer showed that USG had significant effect on all growth parameters at all samplings except LAI and number of total tillers hill ha-1 at 30 DAT. The interaction effects on growth parameters did not varied significantly. Most of the growth parameters at all levels of seedling hill ha-1 gave higher values with USG than those with urea. The yield contributing characters like effective tillers hill ha-1 , number of spikelets panicle ha-1 and number of filled grains panicle ha-1 were maximum with single seedling hill ha-1 and the values were 8.3, 140.1 and 109.6, respectively. The highest grain yield was 5.71 t ha ha-1 with single seedling hill ha-1 which was statistically similar to 2 seedlings hill ha-1 (5.56 t ha ha-1 ) but differed from 4 seedlings hill ha-1 . The lowest yield was with 3 or 4 seedlings hill ha-1 but number of total tillers hill ha-1 (12.6) and straw yield (8.20 t ha ha-1 ) were significantly higher with 4 seedlings hill ha-1 than 1 or 2 seedlings hill ha-1 .
