Guava trees (cv. tun-san-yua-ba) were Planted in the experimental farm, TCHU, Taichung city in 1970, to study the effect of training and pruning on the tree vigor, fruit yield, fruit quality and harvest period. The results of two years observation were as follows:
(1)The natural tree form without too much Pruning was the most desirable form and with high yield.
(2)Light pruning trees had fruits with best quality and higher yield but owing to the large tree crown, fewer trees per hactare, resulted in lower yield per hactare, as compared with moderate and heavy pruning trees.
(3)Heavy pruning trees bearing fruit evenly the whole year, and light Pruning trees bearing most in Autumn to meet the market need.
(4)Grava trees bearing fruit throughout the whole year, with low yield both in cold-dry Winter and hot-rainy Summer. The large and good quality fruits were Autumn fruits. Various farm practices in Autumn and Winter are necessary for a good Productive orchard.
