Test on the Exploitation of the Madagascar Peanut Sector, Case of the Volcanic Region of Itasy

Abstract

The Itasy region, our study area, is one of the 22 regions of Madagascar, and is possibly with a vocation and a great agricultural potential; among them, there is also the groundnut industry. So far, there have been very few scientific studies done around this area. This leads us to have a further study to the area. We carried out two geological reconnaissances and sampling missions in two sectors: one was in the commune of Ampary district of Soavinandriana and the other one was in the commune of Anosibe-Ifanja, followed by various analyses and tests of culture. Our goal is to carry out more scientific studies on the valuation of the groundnut industry in the Itasy region. In the laboratory we carried out various analyzes: chemical analysis, mineralogical analysis by X-ray fluorescence method, particle size analysis, and peanut culture tests of two varieties, equipment design followed by improvement and various tests extraction of peanut oil.The results of the chemical analysis showed a fertilizing value of the samples. The mineralogical analysis showed the richness of minerals and trace elements of the different samples. Cultivation tests showed positive action to the groundnut variety of groundnut volcanic soil than to the variety of peanut menakely. The extraction tests have told us that the more the pressure force increases, the more extraction efficiency increases.
