Abstract: The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University during November 2016 to June 2017 to investigate the effect of spacing of planting on the yield performance of some aromatic rice varieties in Boro season. The experiment comprised three varieties viz. BRRI dhan50, Basmati and BRRI dhan63, six spacing of planting viz. 25 cm × 20 cm, 25 cm × 15 cm, 20 cm × 20 cm, 20 cm × 15 cm, 15 cm × 15 cm and 20 cm × 10 cm. The experiment was laid out in a randomized complete block design with three replications. The highest grain yield (4.01 t ha-1) and harvest index (47.38 %) were recorded in BRRI dhan50 followed by BRRI dhan63 while the lowest grain (3.44 t ha-1) and highest straw (5.11 t ha-1) yields were recorded in Basmati. Planting spacing 20 cm × 10 cm gave the highest grain (4.54 t ha-1) and straw (5.92 t ha-1) yields compared to other spacing. BRRI dhan50 along with 20 cm × 10 cm spacing produced the highest grain yield (5.08 t ha-1) while the highest straw yield (6.71 t ha-1) was recorded in Basmati at 20 cm × 10 cm plant spacing. Based on the present study it can be concluded that BRRI dhan50 along with 20 cm × 10 cm spacing of planting appears as the promising combination for higher grain yield in Boro season.
