Water catchment systems "in situ" about the growth of jatropha.
2014
The jatropha (Jatropha curcas L.) is an oilseed plant of the uphorbiaceae family, native to the Americas and is currently considered an alternative for biodiesel production, demanding heatstroke and drought resistant. In this research, the studies were designed to evaluate the development of culture of jatropha, testing, planting techniques that contribute to greater efficiency of rain water harvesting in situ. The experiment was conducted on the premises of the Experimental Station of the National Institute of Semiarid - INSA, located in Campina Grande-PB. The statistical outline utilized was in randomized blocks with three replications and studied five techniques of catchment of rainwater in situ. Throughout the growth cycle variables are benefited by the forms of soil preparation, to promote water harvesting in situ, compared to treatment with no technical catchment.
