Abstract
An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University in 2015 to observe the effect of row arrangement and nitrogen level on the growth and yield of transplant Aman rice cv. BRRI dhan34. The experiment comprised three row arrangements viz. single, double and triple row arrangement and six nitrogen doses viz. 0, 40, 60, 80, 100 and 120 kg N ha -1 . The experiment was laid out in a randomized complete block design with three replications. The highest number of total tillers hill -1 (9.43), number of effective tillers hill -1 (6.44), number of grains panicle -1 (140.03), grain yield (4.68 t ha -1 ), straw yield (7.28 t ha -1 ), biological yield (11.96 t ha -1 ) and harvest index (39.13%) were recorded in double row arrangement and the lowest grain yield (4.13 t ha -1 ) was obtained in triple row arrangement. Application of nitrogen fertilizer showed significant differences in all yield components except 1000-grain weight. In case of interaction, the highest plant height (143 cm), number of total tillers hill -1 (10.5), number of effective tillers hill -1 (7.09), number of grains panicle -1 (150.10), grain yield (5.65 t ha -1 ) and straw yield (8.17 t ha -1 ) were recorded in double row arrangement fertilized with 80 kg N ha -1 and the lowest grain yield (3.12 t ha -l ) was obtained from the combination of triple row arrangement with 0 kg N ha -1 . So, cultivation of BRRI dhan34 in double row and fertilized with 60 kg N ha -1 is a promising technique to obtain the highest grain yield.
