Abstract

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July 2016 to December 2016 to find out the effect of seedlings age and different nitrogen (N) levels on the yield performance of transplant Aman rice (cv. Binadhan-15). The experiment comprised four ages of seedlings  viz., 15 , 20 , 25, 30 day old and four levels of nitrogen viz., 0 ,55 , 75 and 95 kg N ha–1 following randomized complete block design (RCBD) with three replications. The effect of age of seedling, nitrogen levels and their interactions were significant on growth, yield and yield contributing characters of transplant Aman rice. The highest plant height at harvest (92.67 cm), number of effective tillers plant–1 (8.70), grain (4.55 t ha–1) and straw yields (5.49 t ha–1) were obtained from 75 kg N ha–1. By using optimum seedling age at 15 DAT the highest plant height (102.7cm at harvest), number of effective tillers plant–1 (8.29), grain (4.01 t ha–1) and straw (5.06 t ha–1) yields. In interaction, 75 kg N and 15 days old seedling produced highest plant height (106.3 cm at harvest), number of effective tillers plant–1 (9.42), grain (5.0 t ha–1) and straw yields (6.10 t ha–1). From the above results of the present study, it may be stated that Binadhan-15 is grown successfully for obtaining maximum yield with 75 kg N ha-1 and 15-day old seedling age individually or in combination.
