Abstract

An investigation was carried out during aman season, 2005 at the Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna. Local aman rice variety Jatai was tested against 4 different levels of nitrogen viz. 0, 20, 40 and 60 kg N ha-1. The experimental results revealed that nitrogen levels significantly affected plant height (cm), number of tillers hill-1, weight of 1000-grain (g), grain yield (tha-1), biological yield (t ha-1) and harvest index (%). Higher N dose (60 kg ha-1) produced higher plant height (127.57 cm) and panicle length (20.43 cm). The highest number of tillers hill-1 (13), effective tillers hill-1(11.70), filled grains panicle-1 (61.25), weight of 1000 grain (30.25 g), grain yield (4.17 t ha-1), biological yield (12.46 t ha-1) and harvest index (33.48 %) were produced with 40 kg N ha-1. The lowest grain yield and yield contributing characters were produced by control treatment (0 kg N ha-1).
