Growth, Yield and Biochemical Qualities of Spinach (Spinacia oleracea) being Influenced by the Foliar Application of Chitosan

The study was carried out to evaluate the effects of various doses foliar application chitosan on spinach growth, yield, and quality characteristics (including chlorophyll-a, chlorophyll-b, total chlorophyll, carotenoids, ash, main nutrient contents). Randomized Completely Block Design (RCBD) used set up field experiment, with six treatment combinations [T0 = Control (no application), T1 100 ppm solution, T2 150 T3 200 T4 250 T5 300 solution] three replications. results revealed that applying at different significantly affected growth (viz., plant height, number leaves per plant) yield spinach. Moreover, due doses, there were notable differences observed in phenol, ash contents sample contained an average 13.61–15.82 mg g chlorophyll–a, 9.16–10.18 chlorophyll–b, 22.77–25.85 chlorophyll. On contrary, effect showed a statistically significant difference P, K, Zn, Fe highest amounts K obtained from T3. However, most biochemical properties reduced by higher (treatments T5) chitosan. Finally, according study's findings, rate affects pigments,
