ABSTRACT 

The experiment which likened the execution of high-placed outcome briefly cold duration and heat-tolerant varieties under increasing temperature was carried out in two successive crop seasons (2017-18 and 2018-19) at a farmer's field in Maniksari Upzila within Khagrachari Hill District during the Rabi season (November–March). Early mature wheat types made available by BARI were sown at the ideal time and were heat, saline tolerant as a coping strategy for extreme heat stress. There were six short time wheat cultivars developed recently in heat and stress (BARI Gom 25, BARI Gom 28, BARI Gom 30, BARI Gom 32, BARI Gom 33, and Advance Line BAW 1147). BARI Gom 33 (3.86 t/ha and 3.80 t/ha) and BARI Gom 30 (3.78 t/ha and 3.56 t/ha) produced the highest crop yields over the course of a few years. BARI Gom 32 (3.00 t/ha and 3.40 t/ha), Advance line 1147 (2.96 t/ha and 3.04 t/ha), and BARI Gom 28 (2.59 t/ha and 3.10 t/ha) were found the highest yields. BARI Gom 25 (2.74 t/ha and 2.89 t/ha) had the lowest yield. The quantity of biomass yield and wheat crop output differed significantly, but the other characteristics had little bearing. BARI Gom 25 was the earliest maturing variety, and BARI Gom 33 generated the highest crop output compared to other varieties. The highest benefit cost ratio (BCR) was 1.48 displayed by BARI Gom 33 and the lowest by BARI Gom 25 which was 1.08. According to the experiment's findings, BARI Gom 33 was among the six kinds in the Khagrachari Hills' early high producing and most adaptable variety. BARI Gom 30 also may be cultivated in the Khagrachari Hills District.
