Growth and yield performance of Sweet Pepper varieties by exogenous application of chitosan-raw-material (Shrimp shell powder)

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 (139.18g).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-rawmaterial 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.
