Abstract

Abstract Jatropha curcas L. is a terminal flowering plant. The use of planting material from the beginning which has many branches (multi-entrenched seedlings) will certainly have the opportunity to provide higher yields, compared to single-stemmed seedlings. Three-month-old multi-entrenched seedlings (b1 = single-stemmed seedlings, b2 = seeds with two branches, b3 = seeds with three branches, and b4 = seeds with four branches) raised in polybags were planted in the field to evaluate the performance of these multi-entrenched seedlings in a Randomized Block Design with three replications, and each treatment consisted of five tree units. The result shows that the use of branched seedlings has a significant effect on the yield of Jatropha started in the first year of cultivation. Seedlings with two entrises were very well multi-entrenched seedlings used, offered seed yield about 408.2 g per tree in the first year, and 1,118.4 g in the second year of cultivation.
