Plant spacing and pruning effect on yield productivity of jatropha

The study examined the effect of plant spacing on yield productivity and assessed yield after pruning for jatropha. The experimental design was split-plot in a randomized complete block, including two main-plots of planting space comprised of 1 × 1.5 m (S1) and 2 × 1.5 m (S2), and 14 sub-plots were jatropha varieties of 11 interspecific hybrids crossed between jatropha and peregrina, and three jatropha varieties with four replications. The data collection was done continuously for two years and found that planting space was not significantly different in traits. In year one, S1 showed a higher value of fruit yield ha^− 1 and seed yield ha^− 1 than S2, while in year two, S2 displayed a higher mean, fruit weight plant^− 1, and seed weight plant^− 1 than S1. The inter-specific hybrid jatrophas, KUJL70 and KUJL106 gave more seed yield ha^− 1 and oil content than other jatropha breeding lines.
