“…The results of the Correlation Test found that the content of Polyphenols, Catechins (EGCG), Flavonoids, and Caffein is influenced by soil nutrients pH, C org, N, P2O5 available, P2O5, K2O,CaO,Ca,and Mg. The results of this study are in line with (Hukom, 2020) research that the application of liquid fertilizer without the addition of N in the dry season affects the increase in the active ingredient content of EGCG tea shoots to the highest to reach 12.53%. The EGCG content of rainy season tea shoots is always lower than the dry season, because of high rainfall with long time intervals, resulting in a lot of N nutrients leaching out of the plant root area resulting in N stress which affects the decrease in chlorophyll biosynthesis.…”

This research was conducted on the tea plant which has the scientific name Camelia Sinesis L at the Tambi Plantation Unit (UP) located in Tambi Village, Kejajar District, Wonosobo Regency. The purpose of this study was to determine the effect of soil nutrients and the year of cut on the quality of tea leaves at UP Tambi. The flow of thought in this research, where after taking soil samples and leaf samples at the Tambi Wonosobo Tea Plantation Unit with the 4th cutting year (2018) and the 2nd cutting year (2021) then proceed with laboratory testing to determine nutrient content soil and substance content of tea leaves to measure the quality of tea plants. The sample for this study was taken using the instant sample method (Grab Sample), where the samples were taken directly from the soil body at a predetermined location with a depth of 20 cm from the soil surface, while the leaf sampling also used the Grab Sample method. The results of this study showed that the Correlation Test found that the content of Polyphenols, Catechins (EGCG), Flavonoids, and Caffein was influenced by soil nutrients pH, C org, N, available P2O5, P2O5, K2O, CaO, Ca, and Mg, meaning that there the effect of soil nutrients on the quality of tea leaves in the Tambi Plantation Unit (UP), Furthermore, there was no effect of the year of cutting on the quality of the tea leaves as shown by the results that in the 4th cutting year (2018) and the 1st cutting year (year 2021)

“…Hal tersebut sangat penting karena berkaitan dengan kebutuhan air tanaman dan implementasi manajmen hara tanaman secara terpadu di perkebunan. Hasil Penelitian di Perkebunan Teh Tritis menunjukkan bahwa bobot segar dan bobot kering produktivitas pucuk teh tertinggi terjadi di musim hujan namun rendemen, kandungan bahan aktif Epigallocatechine gallate (EGCG) dan sifat antioksidannya di musim hujan jauh lebih rendah dari musim kemarau [6,9,10] . Hal ini disebabkan karena kondisi curah hujan yang tinggi menyebabkan pertumbuhan pucuk lebih cepat dengan kadar air jaringan yang tinggi.…”

Efforts to increase the productivity and quality of tea shoots are strongly influenced by local climatic and weather conditions at each plantation location. The existence of climate change globally causes climate change fluctuations and weather elements in almost all tea plantation locations in the world from year to year. Determination of the local climate at each tea plantation location is important in establishing a stable and sustainable production management program and the quality of tea shoots. The weather parameters used for the determination of the start of the local rainy season (AMH) and the start of the dry season (AMK) at the tea plantation location in Tritis hamlet are the amount of rainfall and basic rainy days determined by the Meteorology, Climatology and Geophysics Agency (BMKG). Rainfall data and local dasarian days of rain for a period of one year were analyzed using subjective descriptive methods involving graphical analysis and spatial analysis. The results showed that the beginning of the rainy season (AMH) in Tritis tea plantation was included in scenario 4 where AMH occurred in October 3 with the amount of rainfall ˃ 50 mm and the number of rainy days ˃ 6 days while the beginning of the dry season occurred in May 2 with the amount of rainfall ˂ 50 mm and the number of rainy days ˂ 6 days.Key words: AMH, AMK, Rainfall, Dasarian, Rainy Day, and Tea Plantation.
