NODA-LEYVA, Yolai  e  MARTIN-MARTIN, Giraldo Jesús. Preliminary results of the pruning and application of FitoMas-E on the yield of Jatropha curcas and associated crops. Pastos y Forrajes [online]. 2016, vol.39, n.4, pp. 246-251. ISSN 2078-8452.

In order to determine the effect of pruning and application of FitoMas-E on the yield of Jatrophacurcas and associated crops, through a completely randomized block design, six treatments were studied: T1: control without pruning and without leaf application; T2: control without pruning with leaf application; T3: pruning at 50 cm without leaf application; T4: pruning at 50 cm with leaf application; T5: pruning at 100 cm without leaf application; T6: pruning at 100 cm with leaf application. The days to sprouting, number of emerged sprouts, number of productive branches per plant, number of racemes per plant, number of fruits per raceme, harvested fruits, weight of the fruits, weight of the seeds, were evaluated, and the fruit and seed yields were also estimated. During the experimental stage squash and beans were intercropped and the agricultural yield was calculated. T4 was the most precocious in sprouting (6 days), and it also reached the highest number of sprouts (10), of productive branches (12) and 1,2 t of seed/ha. The squash and beans had yields of 7,0 and 2,7 t/ha, respectively. It is concluded that pruning, combined with the leaf application of FitoMas-E influences favorably the morphological and productive variables of J. curcas, for which continuing these studies is recommended.
