Abstract
Pruning is an agronomical practices resulting in inducing of more branches, and then increasing inflorescences number leading to higher seed yield. The objective of the research was to determine the effect of pruning time on the yield performance of Jatropha curcas L. A series of experiments was conducted from November 2008 to November 2013 at dry land of North Lombok, West Nusa Tenggara, Indonesia using West Lombok genotype. The experimental design was Randomized Block Design with three replications. There were four treatments i.e. a) without pruning, b) pruning of sapling at planting time, c) total pruning at the first year, d) total pruning at the second year es, e) total pruning at the third year, and f), total pruning at the forth year. The result showed that plant development and maintenance canopy was an important agronomic practice to obtain high seed production. The best time for pruning during 5-years production cycle were total pruning at the second year with seed yields during 5 years production cycle (from the first to the fifth year) were 718.4 kg Ha-1; 1,135.4 kg Ha-1; 1,972.9 kg Ha-1; 5,436.3 kg Ha-1, and 8,271.6 kg Ha-1 respectively. The total yield was higher (16,314.6 kg Ha-1), compared to un-pruned tree (14,800.1 kg Ha-1). The increase was about 10.2 %.
