Abstract :This research was conducted to determine the effect of applying shading on some agronomical traits of the tea plant (Camellia sinensis (L.) Kuntze) in 2024. The study was carried out during the first shoot period of tea and shading nets were used to prevent the passage of sunlight at different rates (Control, 35%, 55% and 75%). In the study, shoot length (cm), number of leaves per shoot (unit), leaf length (cm), leaf width (cm), leaf color, fresh leaf yield (g-1 m2-1), dry matter content (%), total polyphenol (%), and caffeine rate (%) were examined in tea plants. As a result of the study, it was determined that the shoot length and the dry matter rate were not affected by shading; however, other examined traits were affected statistically and significantly (P<0.01) depending on the shading rate. The highest values in terms of leaf length, leaf width and leaf color were obtained in the control and 35% shading rates, while the highest number of leaves on the shoot was obtained in the 75% shading rate. As the shading rate increased, the number of leaves per shoot also increased, while the fresh leaf yield tended to decrease. At 75% shading rate, total polyphenol and caffeine levels were at the highest level, and the decreasing the shading rate led to a decrease in the values belonging to these quality elements.
