To explore the effects of 6-Benzylaminopurine (BAP) on leaf characteristics and grain yield of aromatic rice the present investigation was carried out. The experimental materials comprising four concentrations of BAP (0 ppm, 30 ppm, 60 ppm and 90 ppm) and three aromatic rice cultivars (Chinigura, Kataribhog and Kalijira). The experiment was laid out in randomized complete block design and replicated thrice. Statistical analysis indicated that leaf characteristics and grain yield of aromatic rice were significantly influenced by the concentrations of BAP. Leaf number, leaf length, leaf breadth, leaf dry weight, panicle length, 500-grain weight and grain yield were increased with the increasing concentration of BAP. Among the concentrations, the 90 ppm of BAP performed better regarding the parameters studied. Maximum number of leaf, longest leaf, maximum leaf dry weight, highest length breadth ratio of leaf and maximum 500-grain weight was observed in Kataribhog which was statistically at par with that of Kalijira. Broader leaf was observed in Chinigura, whereas longest panicle and highest grain yield was recorded from Kalijira. Among different treatment combinations the highest grain yield (4.10 t ha-1) was recorded from Kalijira × 90 ppm BAP treatment and the lowest grain yield (3.08 t ha-1) was recorded from Chinigura × control treatment.
