Abstract :

The tea plant (Camellia sinensis (L) O. Kuntze) can grow well in areas with an annual rainfall between 1,150 up to 6,000 mm, optimum temperature around 14-250C, and minimum air humidity is 70%. On the high ground tea plant cultivations, long dry season is marked by the number of dry months more than 2 months with the rainfall intensity below 60 mm. Long duration of dry season in 2015 affected on microclimate and morphology of tea in Gambung Tea Plantation (1,350 m asl). Observations that made at Gambung tea plantation, as represent of highland tea plantation with an altitude of 1,350 meters above sea level (m asl) showed that during 2015 experienced 4 months, more than the previous two years with maximum of 2 dry months. Maximum air temperature in 2015 reached 30.80C, highest temperature compared to 2013 and 2014 at 25.60C and 26.90C. Relative humidity is lowest in 2015 dropped at 65.5% compared to the year 2013 and 2014 amounted to 79.1% and 73.6%. Soil water content dropped to 6.00% below minimum level. In this condition only 54.70% of plant were in normal growth condition, others were experienced symptom of dryness in various levels. Anticipate the impact of drought can be started with the use of organic matter and the management of shade trees as regulators microclimate in the tea plantations.
