Abstract

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to December 2015 to evaluate the effect of row spacing on the performance of three short duration transplant Aman rice varieties. The experiment consisted of three rice varieties viz. Binadhan-7, BRRI dhan39 and BRRI dhan49 and five row spacings viz. 15cm×15cm, 20cm×15cm, 25cm×15cm, 30cm×15cm, 35cm×15cm. The experiment was laid out in randomized complete block design with three replications. Results revealed that crop characters, yield contributing characters and yield were significantly influenced by variety, row spacing and their interaction. The highest plant height (112.31 cm), panicle length (24.74 cm), number of grains panicle-1 (120.35) and biological yield (9.88 t ha-1) were obtained in BRRI dhan39,while the highest number of total tillers hill-1 (10.00), effective tillers hill-1(8.35), grain yield (3.75 t ha-1) and harvest index (41.10 %) were found in BRRI dhan49. In case of row spacing the tallest plant (107.70 cm), the highest number of effective tillers hill-1 (9.23) were obtained at 35cm × 15cm row spacing, whereas the highest number of grains panicle-1 (119.52), 1000-grain weight (24.87 g), grain yield (3.80 t ha-1) and harvest index(40.29) were obtained at row spacing 25cm × 15cm. In case of interaction the highest grain yield (4.44 t ha-1) and harvest index (46.20%) were obtained in BRRI dhan49 with the row spacing of 25cm × 15 cm. The experimental result concludes that BRRI dhan49 transplanted at 25cm × 15cm row spacing could be a promising practice in terms of grain yield.
