摘要：An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to December 2014 with a view to finding out the effect of variety and level of nitrogen on the yield performance of fine aromatic rice. The experiment consisted of three varieties viz. Kalizira, Binadhan-13 and BRRI dhan34, and six levels of nitrogen viz. 0, 30, 60, 90 kg N ha -1 , USG 1.8 g 4 hills -1 (55 kg N ha -1 ) and USG 2.7 g 4 hills -1 (80 kg N ha -1 ). The experiment was laid out in a randomized complete block design with three replications. Variety, level of nitrogen and their interaction significantly influenced the yield of aromatic rice. The highest grain yield (3.33 t ha -1 ) was obtained from Binadhan-13 followed by BRRI dhan34 (3.16 t ha -1 ) and the lowest grain yield was found in Kalizira (2.11 t ha -1 ). In case of N, the tallest plant (140.3 cm), highest number of effective tillers hill -1 (11.40), grains panicle -1 (152.8), and grain yield (3.32 t ha -1 ) were obtained when fertilized with USG 1.8 g 4 hills -1 and the lowest values were found in 0 kg N ha -1 . Therefore, Binadhan-13 fertilized with USG 1.8 g 4 hills -1 (55 kg N ha -1 ) appeared as the promising practice for appreciable grain yield. J. Environ. Sci. & Natural Resources, 9(1): 41-45 2016
