EVALUATION OF TEN AROMATIC RICE CULTIVARS IN RELATION TO MORPHOLOGICAL TRAITS AND YIELD IN AMAN RICE

Abstract

The experiment was carried out in the Experimental Farm of Sher-e-BanglaAgricultural University, Sher-e-Bangla Nagar, Dhaka during June to November(Aman season), 2019 to study the morphological characteristics and yield often aromatic rice cultivars in rice. Ten traditional aromatic rice cultivars viz.,Chinigura, Begunbichi, Madhumala, Katarivog-2, Kalijira, Badshavog,Katarivog-1, Dolavog, Shadasone and Khaisone were used as the treatment ofthis experiment. The experiment was laid out in a Randomized Complete BlockDesign (RCBD) with three replications. Data on different morphological traitsand yield were recorded and marked differences were observed for differentcultivars. Plant height at 30, 60 and 90 DAT and at harvest, the tallest plant55.61, 108.20, 142.40 and 161.40 cm, respectively) was found from the cultivar Madhumala, while the shortest plant (41.81, 81.36, 115.30 and 136.00 cm,respectively) from Dolavog. At 30, 60 and 90 DAT and at harvest, themaximum number of tillers hill -1 (8.72, 17.70, 24.56 and 25.06, respectively)was found from Kalijira and the minimum number (6.80, 10.50, 16.00 and16.50, respectively) from Madhumala. The maximum effective tillers (18.24)were found from Kalijira, while the minimum number (12.67) fromMadhumala. The longest panicle (21.00 cm) was recorded from Kalijira,whereas the shortest from Dolavog. The maximum number of filled grainspanicle -1 (148.20) was found from Kalijira and the minimum number (78.60)from Katarivog-2. The lowest sterility percentage (7.26%) was recorded fromKalijira, whereas the highest (25.71%) from Katarivog-2. The highest weightof 1000 grains (22.76 g) was observed from Madhumala and the lowest weight(9.12 g) from Shadasone. The highest grain yield (3.42 t ha -1 ) was found fromKalijira, whereas the lowest (2.11 t ha -1 ) from Madhumala. The highest strawyield (6.12 t ha -1 ) was recorded from V 5 (Kalijira), while the lowest (4.70 t ha )from Madhumala. Kalijira produced longest panicle, highest number of effective tillers, filled grains, total grains panicle -1 (166.50) and consequently,provided the highest grain yield, straw yield and biological yield. So, the ricecultivar Kalijira can be considered as best among the studied aromatic ricecultivars. -1
