Abstract: A field experiment was conducted to study the effect of napthalene acetic acid (NAA) on morpho-physiological, yield and yield characteristics of three aromatic rice cv. Chinigura, Kataribhog and Kalijira. The NAA was applied 0, 50, 100, 150 and 200 ppm at vegetative and pre flowering stages. The NAA spraying of150 ppm had the stimulatory effect on the tiller number hill-1of different aromatic rice variety had also positive effect on chlorophyll-a, total chlorophyll content, calcium and magnesium content of aromatic rice flag leaf of Chinigura and Kalijira cultivars but 100 ppm for Kataribhog. Some yield contributing parameters of aromatic rice such as grain number per panicle, grain weight per panicle and total grain yield were influenced due to the interaction effect of variety and levels of NAA. The highest grain yield was in Chinigura cultivar (2.77 t ha-1) twice spraying using 150 ppm NAA. Out of the three rice, Chinigura performed better considering growth, physiological parameters and yield traits. The foliar spraying with 150 ppm NAA had the better stimulation on growth on yield of Chinigura and Kalijira but 100 ppm for Kataribhog. NAA promoted physiological functions and enhanced the growth and yield of aromatic rice cultivars which might be an alternative practice for rice production in Bangladesh.
