ADAPTABILITY ASSESSMENT OF TRADITIONAL AROMATIC RICE CULTIVARS IN BORO SEASON BASED ON GROWTH VARIABLES, AROMA QUALITY AND YIELD

Abstract

The experiment was conducted at the experiment field of Sher-e-Bangla Agricultural University (SAU), Dhaka during the period from December 2018 to May 2019 to study the adaptability assessment of traditional aromatic rice cultivars in Boro season based on growth variables, aroma quality and yield. The experiment comprised of single factor (variety). Twelve aromatic rice varieties viz., Kalizira, BRRI dhan 50, Dulabhog, Shakkhorkhora, Madhumala, Badsabhog, Kataribhog-2, Chiniatap-2, Kataribhog-1, Zirabhog, BRRI dhan 34 and Chiniatap-1 were considered for the present study. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data on different growth, yield contributing parameters, yield parameters and quality parameters were recorded and analyzed statistically. The highest number of effective tillers hill -1 (26.00), length of panicle (31.00 cm), number of total grains panicle -1 (221.00), number of filled grains panicle

(179.30), grain yield (3.52 t ha -1 ), straw yield (5.28 t ha -1 ), biological yield (8.80 tha ) and harvest index (40.00%) were found from BRRI dhan 50 whereas the lowest grain yield (1.68 t ha -1 ), straw yield (4.28 t ha -1 ), biological yield (5.96 t ha ) and harvest index (28.1900%) were recorded from Madhumala. In case of aroma quality, variety Zirabhog showed strong aroma whereas the mild aroma was found from BRRI dhan50. So, considering overall performance, BRRI dhan50 gave best performance, and this variety may be considered as best among the varieties under the present study. -1 -1 -1
