Daftar Isi:

The objectives of this research is to identity the influence of the branch secondary barbering. To words the growing and the result of some numbers of jatropha curcas L crossing plant in the third year. The experiment has been held in jorongan village, leces, probolinggo. This research is using divided partition design with tree times repetitions. It is also using two samples in every number of crossing plant. The material plants are number 2, 4, 5, 6, 7, 16, 18, 22, 24, 37, end 39 in the crossing plant that nave reproductive phase in the third year. The observation to see the growth has been held in every 14 days, except for the weight parameter of 100 dry seeds only observed in the end of harvest. The result that the interaction between secondary branch barbering and the number of crossing plant research doesn’t real influence, but the influence of every factor is real. The secondary branch barbering show the real interaction of total tersier parameter branch, the weight of the dry seeds and the weight of 100 seeds. While number of crossing plant result has areal influence fro the secondary branch parameter in the age of 90 days, the plant length of 60-150 (cm), the canopy diameter of 60 (cm), the total fruit of 98, weight dry seed weight end 100 seeds weight. While the barbering has influenced for all avalaible parameter. Except dry seeds weight in the all age of observation.
