Abstract

The present study aimed to investigate the effects of chitosan application on the yield and quality of rockets. “Bengi” rocket variety was used as a plant material and chitosan was applied to leaves at four different doses (0 (control)–75–150–300 ppm). The results revealed that the yield values varied between 1691–1914 g m-2, plant height between 24.33–27.92 cm, and leaf width between 4.56–5.71 cm among the applications. The total dry matter, chlorophyll, total phenolics, vitamin C, and antiradical activity values were determined to range between 7.71% and 8.68%, 34.15 and 36.68 SPAD, 104.67 and 180.84 mg 100 g–1, 126.63 and 143.51 mg 100 g–1, and 63.77% and 71.87%, respectively. The highest total phenolic and antiradical activity values were obtained at the 300 ppm application and the highest vitamin C values were obtained from the control group. a* and h° values varied between –17.87 to –18.71 and 124.09 to 125.78. Chitosan applications decreased nitrate accumulation compared to the control group. It was determined that the 75 ppm chitosan dose used in the study was better in terms of yield, plant height, leaf width, total dry matter, chlorophyll, a*, h°, and nitrate accumulation parameters and was the recommended dose for rocket cultivation.
