Abstract
Cotton (Gossypium spp.) is an important cash crop in Bangladesh and serves as the primary raw material for the textile industry. Growth and development, yield and fiber quality of cotton production are negatively impacted by excessive soil salinity. To ensure effective cotton production, it is crucial to select varieties that are well-suited to the coastal area. The research was conducted at the farming field of the research field in the Department of Agriculture, Noakhali Science and Technology University, Noakhali, Bangladesh, during the period of November 2024 to May 2025. The main objective was to evaluate the three cotton varieties that are suited for cultivation in coastal areas. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Plant height (169.39 cm), branch number per plant (18.66), initial flower opening (67.43 days) and yield contributing parameters such as balls per plant (23.46), ball length (5.16 cm), ball diameter (15.94 cm), weight of individual cotton ball (4.77 g), yield per plant (111.99 g), yield per plot (2239.82 g) and yield per hectare (7.47 t ha-1) all the studied parameters performed better in the hybrid variety Rupali-1, followed by Shuvra-3. On the other hand, inbred cotton varieties such as CB-15 are inferior to hybrid varieties. Hybrid varieties outperform in traits like ball size, branching, and early flowering, benefiting from genetic diversity and improved physiological efficiency. The findings of the experiment indicated that hybrid varieties performed better in all the parameters than inbreed varieties in coastal areas. Therefore, it can be concluded that, hybrid varieties Rupali-1 and Shuvra-3 may be suitable for cultivating in coastal regions of Bangladesh.
