Growth and yield performance of local T. aman aromatic genotypes under the southern region

The present experiment was conducted at the Research Field Laboratory of the Department of Agricultural Botany, Patuakhali Science and Technology University (PSTU), Patuakhali during the period from July to December 2013 to evaluate the local T. aman aromatic rice genotypes for obtaining the most productive genotype considering growth and yield performance under southern region. The five local T. aman aromatic rice genotypes viz. Kataribhog, Radhunipagal, Kalizira, Shakhorkhana and Chinigura were as used planting materials and laid out in RCBD with three replications. The genotype Chinigura produced significantly the tallest plant (155.2 cm), no. of total tillers per hill (12.03), LAI (2.05) and TDM (19.92 g hill ) at vegetative stage (60 DAT). Similarly, no. of effective and noneffective tillers per hill (10.53 and 2.13), total and filled grains panicle (126.80 and 119.10), minimum unfilled grains panicle (7.70), grain, straw and biological yield also higher (2.61, 5.34 and 7.95 t ha, respectively) in Chinigura at harvest. So, Chinigura was the most productive genotype among the studied aromatic genotypes under the southern region.
