Production analysis of seed-derived tea plants (Camellia sinensis (L.) O. Kuntze) across two different seasons
Abstract
Tea (Camellia sinensis (L.) O. Kuntze) is a major economic crop in Indonesia, yet its productivity is strongly influenced by environmental variability, particularly rainfall seasonality. Fluctuating yields under dry and wet conditions pose challenges for sustainable tea production. This study aimed to assess the effects of contrasting seasonal rainfall on seed-derived tea plants' yield and yield components. The research was conducted at a seed-derived tea plantation block in IRITC, West Java, across dry and wet seasons using field observations on tea yield, shoot proliferation, plucking quality, and environmental parameters. Statistical analyses included independent t-tests to compare seasonal differences and Pearson correlation to evaluate the relationships between environmental variables and production outcomes. The findings revealed that tea yield and shoot growth were higher in the wet season than in the dry season, which was statistically significant. Correlation analysis showed that temperature negatively influenced yield and shoot development, while rainfall, soil moisture, and relative humidity were strongly and positively associated with production performance. Conversely, plucking quality (fine and coarse leaves) remained stable across both seasons, indicating resilience to climatic variability and the role of consistent management practices. In short, the wet season provides more favorable conditions for seed-derived tea cultivation, especially in enhancing shoot growth and yield components. At the same time, adaptive management is required to mitigate temperature stress during the dry season.
