Abstract:
An experiment was carried out at the research field of Sher-e-Bangla Agricultural
University, Dhaka during the period from July 2017 -December 2017, to study the
morpho-physiological attributes and yield performance of different aromatic rice
genotypes and to identify the important morpho-physiological and yield contributing
characteristics which might contribute in higher yield. Twelve rice varieties were used
as treatments. The experiment was laid out in a Randomized complete Block Design
(RCBD) with three replications. Data on different morpho-physiological parameters
and yield with yield contributing characters were recorded. The collected data were
statistically analyzed for evaluation of the treatment effect. Results signified that the
