Now-a-days crop production is hindered by climate such as heavy rainfall, flood, hail strom, cyclones etc. So, it is crying need to adopt dynamic crop production tehnologies to increase crop production as well as tocope up with adverse effect of climate changes.However, the present study is conducted to identify the changed climate vulnerable field crop yield factors, to assess the AEZ soil and agro-climatic parameters reducing crop production and to know the South west AEZ based agronomic crops. Data were collected from the capital and the field level conducting interview, discussion and observation using primary source i.e. interview with the respondents from the selected study areas. Primary data were collected through interview. Data were also collected from secondary source through literature review i.e. reference books, newspapers, periodicals, articles from national and international level. Internet sources have been used for research. An attempt was made to include the latest information whenever available. The nature of the study requires combining analytical and empirical approaches in the methodology. Accordingly, both qualitative and quantitative information and data were required. In order to generate database of the study, all necessary information were collected from different primary and secondary sources. Data were also analyzed and presented through the use of necessary figures, tables and charts. From the result it was found that AEZ 13 Khulna Koira showed highest vulnerability 64 % as maximum and AEZ 12 Faridpur Sodor 30% as lowest. Summer season Kharif 1 was found to highest vulnerable as 59%. Rainy season was less vulnerable crop production as 36%.Wide disparities in the level of crop sector development had been observed across the regions. The overall results reveal that some of the regions are in better positions in respect of socio-economic progress, land use pattern, input use, growth performance of HYV rice and food-grains production. The developed regions were ‘Old Himalayan Piedmont Plain and Tista Floodplain’, ‘Karatoya Floodplain and Atrai Basin’, ‘Brahmaputra-Jamuna Floodplain’ and ‘Middle Meghna River Floodplain’ on the basis of land utilization pattern, input use and food-grains production. Analysis of regional disparities reveals that ‘Sylhet Basin and Surma-Kusiyara Floodplain’, Greater Dhaka’, ‘Middle Meghna River Floodplain’ and ‘Lower Meghna River and Estuarine Floodplain’ regions have developed remarkably in the last twenty years.
