Abstract

A field experiment was conducted at the Agronomy field of central research farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from June 2014 to December 2014 to study the influence of nitrogen on growth and seed quality of T. Aman rice variety with interaction effects between nitrogen doses and T. Aman rice varieties. The experiment consisted of two factors such as nitrogen fertilizer and variety. these were as follows: Factor A: Nitrogenous fertilizer (6 levels) viz. N0- controlled, N1- 50% less than BRRI recommended dose, N2- 25% less than BRRI recommended dose, N3- BRRI Recommended dose, N4- 25% higher than BRRI recommended dose, N5- 50% higher than BRRI recommended dose and Factor B: T. Aman rice (3 varieties) viz. V1 – BRRI dhan44, V2 - BRRI dhan54, V3 - BRRI dhan56. The experiment was laid out in a split-plot design with three replications. Nitrogen was assigned to main plots and variety to sub-plots. In case of different levels of nitrogen, the treatment N4 (25% higher than BRRI recommended dose) showed good morphological growth and also produced good quality seed than other treatments which is also true for variety V1 (BRRI dhan44). The interaction of N4V1 (25% higher than recommended dose with BRRI dhan44) treatment is suitable for producing better plant growth and seed of T. Aman rice. The study was concluded that higher dose of urea than BRRI recommendation dose with BRRI dhan44 variety produced good quality seed.
