Crop improvement of the vanilla tree, Vanilla planifolia, using organic fertilizer based on rice straw and manure in Mandritsara-Madagascar

Abstract

Certain theoretical models have been proposed in this article such as in intensive agriculture which proposes agricultural systems based on a model where the dependence of farmers on agro-food industries in order to improve economic efficiency with the aim of increasing and improving the ecological efficiency. Madagascar vanilla is not only one of the main revenue products, but it is also the national pride of the big island. But currently, this vanilla sector finds itself in a delicate situation due to the lack of quality on world markets. Thus, the objective of this study is to improve the cultivation technique of vanilla using organic fertilizer based on rice straw and manure in order to determine its quality. The adopted methodology focuses on the making of organic fertilizers, cultural tests and laboratory analysis. According to the obtained results, the development of vanilla cultivation showed that intensive agriculture could mobilize certain services linked to good management of biodiversity, particularly at the agronomic level, and making it possible to better reconcile agricultural production and the preservation of nature biodiversity.
