DETERMINATION OF AROMA IN BUdhan2 AROMATIC RICE AS INFLUENCED BY DIFFERENT APPLIED FERTILIZER AND PLANT SPACING

Field and laboratory experiments were conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, during boro season of 2015-2016 to asses the aroma (%) and economic performance of newly released aromatic rice variety BUdhan2. The variety was grown with three fertilizer levels, viz., recommended (57-10-8-7-0.9 kg N P K S Zn ha^-1), 50% higher and 50% lower than recommended level and three plant spacing  (20 cm x 25 cm, 20 cm x 20 cm and 20 cm x 15 cm) representing  wider, standard and closer plant densities. The highest amylase (24.7%) was found in growing seed under recommended doses fertilizer application at standard plant spacing (20 cm x 20 cm) but it contained no aroma. In contrast, strong aroma was found in rice produced by lower fertilizer dose at standard plant spacing though it contained the lowest amylase (23.5%).
