Abstract

An experiment was conducted at the agronomy field laboratory, Hajee Mohammad Danesh Science and Technology university, Dinajpur during the period from July to December 2013 to investigate the performance of spacing and level of nitrogen on the growth and yield characters of aromatic rice cv. Kalizira .  The experiment included three spacing namely, 25cm×10cm, 25cm×15cm, 25cm×20 cm and three nitrogen level viz., 34kg, 40kg and 46kg.The experiment was laid out in a randomized complete block design (RCBD) with three replications. Plant height, effective tillers, panicle length, yield, yield contributing characters, qualitative characters were significantly influenced by spacing and nitrogen level of aromatic rice. The result showed that among three spacing, (25cm×15cm) spacing produced the highest number of total tillers hill-1 (17), effective tillers hill-1 (15.61), grains panicle-1             (155.5), the highest grain yield (2.379 t ha-1) was obtained. The lowest grain yield was recorded (1.989 t/ha) with (25cm×10cm) spacing. Among the level of nitrogen ,  significantly effective tillers (15) filled grains ( 162)  grain yield ( (2.5 t ha-1), harvest index (41.48 %)  was obtained from 40kg N ha-1 although 34kg and 46 kg showed similar result in case of total tillers hill-1.  The lowest grain yield (1.5 tha-1)  was recorded with 34kg N ha-1. Result showed that  (25cm×15cm ) and 40 kg N ha-1  was the best combination to produce maximum yield of aromatic rice.
