Abstract:
The experiment was conducted at the Experimental Field of Agricultural
Botany Department, Sher-e-Bangla Agricultural University, Dhaka-1207,
Bangladesh, during July to November, 2016 to study effect of flag leaf removal
on physiological characteristics and yield of six modern rice varieties in Aman
season. The six varieties are BARI Dhan32, BARI Dhan33, BARI Dhan39,
BARI Dhan54, BARI Dhan56 and BARI Dhan62. The experiment was laid out
in Randomized Complete Block Design with four replications. All the test
varieties exhibited superiority in control condition. At harvest, the tallest plant

from BARI dhan54. Among test Aman rice varieties, higher grain yield and
biological yield were also achieved from BARIdhan54. Chlorophyll content

were recorded from BARIdhan54 under control condition. The removal of the
flag leaf reduced grain yield from 17.00 % to 27.70 % in the test Aman rice
varieties.
