Abstrak

This research was aimed to identify and to analyze the characteristics of climate and water availability for crop land of Salak Gulapasir in the new development areas in Tabanan. The reseacrh used survey methods which conducted in each location within the agroecocsystem zone of 400-550 m above sea level (asl), 551 – 650 m asl, and 651-750 m asl. The analysis of water availability in each area was carried out by using Thornthwaite and Mather methods (1957). The results shows water availability in Tabanan area depending on altitude. The  zone 400-550 and 551-650 m asl total deficit respectively 49 mm and 20 mm, with the periods of deficit that occurs in 3 months that is in June, July and August, while 651-750 m asl total deficit of 5 mm with the periods of deficit in two months (July-August). Well handling to the environment and plant factors was very useful in producing fruits in the period out of its season . When water deficit occurs in June, July and August, manipulating environment through the provision of water or mulching should be judged. In the rainy season (December, January, February) a high level of humidity in the canopy can interfere the growing of flowers and fruit, hence it needs to arrange shade plant.
