Abstract
The promotion of bio carburant causes a renewed interest for the plantation of Jatropha curcas (L.) The culture of this nonfood plant has socio-economic and environmental advantages in the experimental zone. However it causes questions in connection with its consequences about the properties of the soils and possible competition with the food crop. The study was carried out in field during three years in soudanian savannah of Chad. The principal objective was to study the possibility of establishing and of diversifying the culture of Jatropha curcas. It is specifically a question of optimizing the development and the production of this plant under the effect of agricultural fertilizers (Organic, mycorhizien and chemical). The device is in completely randomized blocks with five treatments (Compost, mycorhizes, mycorhize-compost mixture, chemical fertilizer and control) and repeated four times. The effect of fertilizers brought was evaluated on the parameters of development and production of J curcas during the three years of culture. The fertilizers had a highly significant impact (pË‚0,001) on the parameters of growth and development (Size, number and area of leaves, number of branches, diameter of basal rod) and of production (A number of fruits and seed yield, total biomass, rate of carbon sequestration) of J curcas with an increase of 20 to 40% compared to the control. More particularly, the organic fertilization and mycorhizes prove to be beneficial substantially to increase the development and the production of J. curcas in optics to popularize its culture in the area of Tandjilé in Chad.
