In this study, the effects of kaolin (M-99-099) applications on the total phenolic and antioxidant contents of tea leaves (Camellia sinensis (L.) O. Kuntze) harvested in three different periods were investigated. For this purpose, four different strategies including standard fertilizer application (T), 3% kaolin+standard fertilizer application (Ka), 6% kaolin+standard fertilizer application (Ka), and control (C) (nothing applied) were used to compare the effects of these strategies on total phenolic content, FRAP values, and DPPH radical scavenging capacities of tea leaves. It has been proven that the kaolin applications, Ka and Ka, increase the phenolic content and antioxidant contents of tea samples. While the kaolin applications have higher values at 1st harvest than those of T and C, they have the lowest values at 3rd harvest.

Nano-selenium fertilizers can promote plant growth and nitrogen availability. However, little information is available on the effects of nano-selenium on tea leaf quality, soil nutrient availability and associated microbe-driven mechanisms. This study examined the effects of nano-selenium on the tea leaf quality and soil nitrogen cycling in 20-year-old tea plantations when the leaves were sprayed with ammonium or nitrate.

Tea is a significant source of flavonoids in the diet. Due to different production processes, the amount of bioactive compounds in unfermented (green) and (semi-)fermented tea differs. Importantly, green tea has a similar composition of phenolic compounds to fresh, unprocessed tea leaves.

not only damages plant leaves directly but also causes a sooty blotch due to the honeydew secreted by the nymphs and adults. This pest is widespread and seems to be spreading from low latitude to higher latitude areas where winters are typically colder, indicating an increase in its cold tolerance. Changes in temperature help insects to anticipate the arrival of winter, allowing them to take defensive measures in advance.
