Title: Effects of rate and method of urea on the growth and yield of T. Aman rice
Abstract: An experiment was conducted at Bangladesh Agricultural University, Mymensingh, during T. Aman 2010 with a view to investigate the effect of rate and method of urea application on the yield and yield components of transplanted aman rice cv. BRRI dhan46. The experiment comprises of two methods of urea application and five rates of urea fertilizer. The experiment was laid out in a randomized complete block design with four replications and the data collected on 10 parameters. The results showed that the method of urea application had significant effect on number of total tillers per hill, number of effective tillers per hill, number of grains per panicle, grain yield, straw yield and harvest index. The highest grain yield (4.66 t/ha) was recorded with split application of urea fertilizer. The effect of urea rate had significant influence on most of the plant characters except panicle length and 1000 grains weight. The highest grain yield (5.07 t/ha) was produced in U1 (140 kg urea/ha). The interaction between rate and method of urea application also significantly influenced most of the parameter studied. The highest grain yield (5.15 t/ha)was recorded with the interaction combination of M1U1 (split application of urea @ 140 kg urea/ha).
