From October 2022 to April 2023, a pot experiment was carried out to examine how several sweet pepper varieties responded to varying concentrations of chitosan-raw-material (Shrimp Shell Powder). The study used a completely randomized design (CRD) with seven replications and involved two varieties viz. BARI Sweet Pepper-1 (V1) and BARI Sweet Pepper-2 (V2) and the four different concentrations (% w/w) were: C0 = 0%, C1 = 0.1%, C2 = 0.5%, and C3 = 1%. The results showed that the V2 (BARI Sweet pepper-2) treatment had the maximum fruit output plant-1 pot-1 (139.18 g). The use of 1% chitosan-raw-material (C3) significantly increased the sweet pepper plant’s growth and productivity. Based on these findings, it can be said that the application of chitosan-raw-material boosted the yield and yield-contributing traits of sweet peppers and some chemical aspects of the soil. When combined, our findings imply that chitosan-raw-material may be beneficial for soil pH, soil organic carbon, and slow-releasing nitrogen supplementation, all of which have an impact on plant growth, development, and yield.
