ABSTRACT

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the period from 10 July 2012 to 15 December 2012 to investigate the effect of plant spacing and nitrogen levels on yield and attributes yield of transplant aman rice cv. BRRI dhan52. The experiment comprised of four plant spacing viz. 25 cm × 20 cm, 25 cm × 15 cm, 20 cm × 20 cm and 20 cm × 15 cm, and five nitrogen levels viz. 0, 40, 80, 100 and 140 kg N ha-1. BRRI dhan52 was used as planting material. Results revealed that plant spacing and N levels had significant effect on the studied crop characters and yield. The plant height, number of total tillers and effective tillers hill-1, grains panicle-1, grain and straw yields increased with increasing plant spacing and N levels.  The highest plant height, number of total tillers and effective tillers hill-1 and grains panicle-1 was observed in the widest spacing of 25 cm × 20 cm resulting, the highest grain yield followed by 20 cm × 20 cm. In contrast, the closest spacing of 20 cm × 15 cm, produced the lowest values of the above mentioned plant parameters and also showed the lowest grain yield. The longest plant, highest number of total, effective tillers hill-1, grains panicle-1, grain and straw yields were observed with 100 kg N ha-1 followed by 140 kg N ha-1. On the other hand, the shortest plant, lowest number of total tillers and effective tillers hill-1, grains panicle-1, grain and straw yields were observed with no nitrogen and the non-effective tillers hill-1 and sterile spikelet’s panicle-1 were recorded the highest. In regard to interaction effect of spacing and N levels, the highest plant height, number of total and effective tillers hill-1 were observed in the widest spacing of 25 cm × 20 cm with 100 kg N ha-1 and resulting the highest grain yield. The lowest values of the above parameters were recorded in the narrowest plant spacing, 20 cm × 15 cm with no nitrogen application. Based on the experimental results, it may be concluded that 25 cm ´ 20 cm spacing with 100 kg N ha-1 would be the best treatments combinations regarding yield and yield attributes of BRRI dhan52.

Key words: Transplant Aman rice, nitrogen levels, plant spacing, BRRI dhan52 and rice yield
