Altitude in the tea plantation effect physiological processes of the  tea plants. That will effect pruning time of tea plant.  Therefore,  this research is carried out to find: 1) Physiological process of tea plant grow in different ages of pruning and altitudes, 2) Optimum age of pruning at differentaltitude. The research was carried out in tea plantation in Inti PT Pagilaran Batang from July to November 2010. The research was conducted in Oversite design using 2 factor, hight place of plantation area (altitude) i.e 700-900 m asl (above sea level), 900-1100 m asl, 1100-1350 m asl and age of prune i.e 1-year after pruning, 2-years after pruning, 3-years after pruning and 4-years after pruning. All the combination treatment was replicated in 3 blocks. The observation were done on several variable of physiologi, growth and yield.All data were analyzed by variant analysis of oversite (multilocation) levels of 5%, followed by Duncant multiple range test level of 5% if there was significantly different in varian analysis.The results showed that at an The 3-years after pruning tea plants showed the lowest characters in fresh and dry shoot weight. Its pointed out bynumber of accumulative pecco shootthan 1, 2 and 4-years after pruning. Then in altitude of 900-1100 m asl and 1100-1350 m asl the 3-years after pruningthe tea plants showed the higher characters in fresh and dry shoot weight.Its pointed out by number of accumulative peccoshootthan the age of 1, 2 and 4-years after pruning.Decline in crop production occurs at the age of 4-years after pruning, marked by number of accumulative pecco shoots, weight per pecco shoot and length of internodia is lower.

Key words: tea, pruning, altitude, ecophysiology of tea
