“…Pruning improves canopy architecture, which promotes fruit production and shrub structure by optimizing branch and leaf arrangement, shrub size, and crown structure and form (Valdes-Rodriguez et al 2020;Pari et al 2018). The effect of different pruning levels and cycles on Jatropha was studied to determine the appropriate pruning pattern for cultivation (Sumed et al 2019;Santoso et al 2016). Furthermore, there has been research into pruning Jatropha for rejuvenation, which is the removal of old, overgrown branches so that the plant can grow new, more substantial branches in their place by hard pruning, which involves cutting the stem of almost all the plants.…”

Reducing plant spacing and pruning Jatropha hybrids may increase yield. The study aimed to investigate the effect of reduced plant spacing on yield productivity, assess pruning tolerance, and discover the relationship between yield and growth traits of Jatropha hybrids. Fourteen Jatropha hybrid genotypes evaluated yield with narrow and standard plant spacing for two years. After the first year, the Jatropha hybrid plants were hard-pruned and allowed to regrow in the second year. It found that although narrower plant spacing might reduce Jatropha hybrid growth and yield per plant, increasing plant density by reducing plant spacing could increase fruit yield, seed yield, and oil yield by up to 65.46%, 64.73%, and 63.25%, respectively, when compared to standard spacing. Furthermore, hard pruning could improve the growth of Jatropha hybrids, and pruning tolerance varied between genotypes. Under narrow spacing, KUJL110 and KUJL70 had the highest yields after pruning, and KUJL110, KUJL30, and KUJL23 had the highest pruning tolerance index (PTI). It discovered a correlation (ranging from 0.49** to 0.86**) between yield traits and plant height, canopy width, and the number of secondary branches. Additionally, a correlation (ranging from 0.51** to 0.83**) was found between oil content and shelling, as well as 100 seed weight. As a result, these traits may serve as an indirect tool for selecting Jatropha genotypes with high-yield traits.
