Abstract

Coffee production success in Indonesia was strongly affected by culture technique, for instance, proper pruning. Pruning Arabica coffee seedling is one of techniques to boost productivity by cutting the plant shoots and stems.This study aims to determine the effectiveness of shoot pruning and 50% pruning on the growth of Arabica coffee seedlings. Data processing was carried out by statistical methods to compare or test the average data of two paired populations using the T test at a level of 0.05. The comparison value (Tcount) is calculated using Equation (1) substituted from equation (2). Parameters observed were plant height, number of leaves, stem diameter and number of branches. The results of the arabica coffee seedling experiment with two treatments of pruning arabica coffee seedlings on the shoots pruning showed that the average plant height, number of leaves, and number of branches, was higher than pruning at the 50% pruning. Meanwhile, pruning 50% of stem diameter showed a higher average than pruning of shoots. It can be concluded that pruning of Arabica coffee seedlings, especially shoot pruning, has a better effect on Arabica coffee seedlings.
