    Abstract
    An experiment was conducted at the research field of Crop Physiology and Ecology during June to December 2018, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur, Bangladesh to investigate the comparative study on morphological, phenological and yield attributes of some Aman rice varieties. BINA dhan7, BRRI dhan56, BRRI dhan62, BRRI dhan71 and BRRI dhan72 were imposed in 20 plot. Different varieties showed significant variation due to booting, heading, anthesis stage, leaf dry matter, stem dry matter, leaf area hill-1 , crop growth rate and net assimilation rate, leaf area index, number of leaves hill-1 and plant height, number of total tillers hill-1 , productive tillers hill-1 , panicle length, grains panicle-1 , fertile grains panicle-1 , sterile grains panicle-1 , test weight, grain yield, straw yield and biological yield. Among the five HYV varieties BRRI dhan72 showed better over rest of the varieties. The highest time require for booting (61.75 days), heading (67.12 days), anthesis (71.75 days), leaf dry matter (13.14 g), stem dry matter (15.45g), leaf area hill-1 , crop growth rate (18.14 gm-2 d - 1 ) and net assimilation rate (8.93 gm-2 d -1 ), leaf area index, number of leaves hill-1 , number of leaves hill-1 (48.75), number of total tillers hill-1 (22.3), productive tillers hill-1 (19.3), panicle length (33.17cm), grains panicle-1 (203.25), fertile grains panicle-1 (192.2), test weight (28.10g), grain yield (6.29 tha-1 ), straw yield (7.42 tha-1 ), biological yield (13.71 tha-1 ) and minimum sterile grains panicle-1 (10.05) were produced by BRRI dhan72 among five elite Aman varieties. Whereas the lowest values for above characters were found in BRRI dhan62.
