Adaptation of winter Barley (Hordeum vulgare) cultivars to climate change in southern part of Bangladesh
Abstract
The present study was conducted at Rural Development Academy (RDA) Agricultural Farm, Kotalipara, Gopalgonj located in southern area of Bangladesh during 01 November, 2023 to 28 March, 2024 to compare the yield performance of important barley varieties and to identify the best adaptive variety of Barley for this area of Bangladesh. Five Barley variety viz. V1= BARI Barley-5, V2= BARI Barley-6, V3= BARI Barley-7, V4= BARI Barley-8, V5= BARI Barley-9 were used for the experiment. Maximum plant height during harvesting, maximum number of tillers per plant and maximum number of effective tillers per plant were recorded with V1 (100.00cm), V5 (3.99) and V3 (2.95) respectively. BARI Barley-5 performed the maximum spike length (10.90cm), maximum number of spikelet of spike (60.45), maximum number of seeds per spike (48.05) and maximum thousand seed weight (31.74gm). As a result BARI Barley-5 gave the maximum grain yield (2.72 t/ha). BARI Barley-5 (94.25 days) and the BARI Barley-8 (95.75 days) was comparatively short duration crop than other varieties. This characteristic of the crop will help to introduce the new cropping pattern in this region and it will the dependency on monocropping. As a result, it can be decided that the BARI Barley-5 was the best variety in terms of grain yield and short duration. It can be concluded that the BARI Barley-5 was the best variety for this AEZ-14 and it can be extended to the local area of Gopaganj district.
