Abstract

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during the period to study the effect of nitrogen on the yield of Boro rice cv. BRRI dhan47. The experiment consisted of four levels of nitrogen viz. 0, 80, 100, and 120 kg N ha-1 as treatment. The experiment was laid out in a randomized complete block design with three replications. The level of nitrogen significantly influenced all the parameters except the weight of 1000-grain. The tallest plant (99.18 cm), highest number of total tillers hill­1 (13.23), maximum number of non-effective tillers hill-1 (4.18), uppermost panicle length (24.60 cm), highest number of sterile spikelets panicle-1 (18.50), top number of total spikelets panicle-1 (153.82) and highest straw yield (6.84 t ha-1) were obtained from 120 kg N ha-1. The greater number of effective tillers hill-1 (10.32), uppermost number of grains panicle-1 (135.32), maximum grain yield (5.36 t ha-1), top biological yield (12.01 t ha-1), and the highest harvest index (44.59%) were recorded from 100 kg N ha-1. The dwarf plant (84.47 cm), lowest number of total tillers hill-1 (7.40), minimum number of effective tillers hill-1 (5.83), bottommost non-effective tillers hill-1 (1.57),  shortest panicle length (21.09), lowest number of grains panicle-1 (84.90), minimum number of sterile spikelets panicle-1 (11.90), fewer total spikelets panicle-1 (100.88), the minimum grain yield (3.20 t ha-1), the least straw yield (4.67 t ha-1),  lowest biological yield (7.87 t ha-1) and the lowest harvest index (40.71%) were obtained from the control treatment (0 kg N ha-1). Based on the findings of the study, it can be suggested that the use of 100 kg N ha-1 would be a promising practice to maximize the growth and grain yield of BRRI dhan47.
