MARTINON MARTINEZ, Antolin Silvestre et al. Evaluation of biofertilizers and hormonal rooting in jatropha (Jatropha curcas L.). Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.2, pp.463-469. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v8i2.66.

The J. curcas is a plant that is cultivated worldwide conventionally, using artificial inputs, in this situation, it is necessary to generate sustainable production technology. The objective of this research was to evaluate the effect of commercial biofertilizers and chemical rooting, on morphological and performance variables in jatropha. The experiment was carried out in june-december 2013, in the experimental field of the Technological University of Izucar of Matamoros (UTIM); the products tested were: Azofer® (Azospirillum), Micorrizafer® (mycorrhiza Glomus genus), Tricovel® (Trichoderma) and rooting chemical Rooting® (auxins and cytokinins). We used a randomized complete block design with 12 replicates. It turned out that rooting Rooting® was the most active, to generate the highest number of lateral branches, higher number of bunches with ripe fruit, ripe fruits per plant and seed weight per plant; of biofertilizers, the mixture of Azospirillum + Trichoderma, generated higher yield (number of mature fruits per plant and seed weight per plant), so this mixture is an alternative in the sustainable production of jatropha.
