Evaluation of agroforestry performance of Jatropha curcas L. cultivated with maize (Zea mays L.) and peanut (Arachis hypogea L.) in Nzila (Centrafrique)

In order to promote Jatropha curcas as bioenergy without food crops are abandoned, the objective of this study is to evaluate the impact of intercropping J.curcas peanuts and corn on the parameters J.curcas growth and production J.curcas, corn and peanuts according to different types of gauges. A randomized block design was used and the R software was used for analysis of variance between the different tested objects. The association with the J.curcas has a significant effect on the weight of the ears of corn after two years of cultivation. The spacing 3x3 m performance and promotes more 4x2 m promotes vegetative growth. The association with peanut has no significant effect on growth and yield. The effect of the combination on the J.curcas is significant as regards the number of secondary branches, seeds and fruit weight. The interaction between intercropped crops is not detrimental to the J. curcas as speculation grown in association have a short cycle and do not develop a root system and strong shade to the J. curcas as speculation grown in association have a short cycle and do not develop a root system and strong shade to compete J. curcas.
