PERFORMANCE OF SOME HYV RICE IN AMAN SEASON AT AEZ1 (Pages : 9 - 20)

As an agro-based country, it is essential to adopt more steps for increasing the production level of rice in Bangladesh. Variety is the most significant factor that plays a crucial role in yield of different crops including rice. A field experiment was conducted at the experimental field of Crop Physiology and Ecology during June to December 2018, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur, Bangladesh to know the comparative study on morphological, phenological and yield attributes of some Aman rice varieties. Binadhan-7, BRRI dhan56, BRRI dhan62, BRRI dhan71 and BRRI dhan72 were imposed in 20 plots. Different varieties showed significant variation due to booting, heading, anthesis, 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. 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 (15.45 g), leaf area hill-1, crop growth rate (18.14 gm-2d-1) and net assimilation rate (8.93 gm-2d-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 (33.17 cm), grains panicle-1 (203.25), fertile grains panicle-1 (192.2), test weight (28.10 g) 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 studied five elite Aman varieties.Download
