ABSTRACT
Kataribhog is one of important fine aromatic rice cultivars in Bangladesh for its pleasant aroma, fine grain and better palatability. A field experiment was conducted to investigate the morpho-physiological and yield characteristics of aromatic rice (cv. Kataribhog) using 6-Benzyl aminopurine (6-BAP). Five levels of 6-BAP were 0, 50, 100, 150 and 200 ppm were exogenously applied at vegetative and pre-flowering stages. The morpho-physiological properties, yield and yield characteristics were significantly varied due to different levels of BAP. The plant height, leaf length, leaf breadth, leaf number plant-1, flag leaf chlorophyll content, tiller number hill-1, panicle length, panicles hill-1, 1000-grain weight, grain yield (t ha-1) and biological yield were increased markedly due to the application of 6-BAP. The highest grain yield was 2.45 (t ha-1) with spraying 150 ppm 6-BAP. The 6-BAP, a synthetic cytokinene stimulated plant height, leaf length, number of tillers hill-1, total chlorophyll content, panicle number hill-1, grain yield (t ha-1), and harvest index at positive way which might be a supportive tool for aromatic rice production in Bangladesh.
Keywords: Aromatic rice, BAP, chlorophyll, kataribhog, yield.
