Title: Characterization and typology of orchards based on mangoes (Mangifera indica L.) in the communes of Djinaky, Diouloulou, Kafountine and Kataba 1 (Casamance, Senegal)
Summary
Orchards based on mangoes (Mangifera indica L.) in Casamance are home to specific culture systems. These culture systems suffer from the attacks of a procession of pests and diseases whose impact would be associated with plant diversity and the functional organization of orchards. This study focuses on the determination of the characteristics and typology of these fruit systems based on their design, compositions and vegetative states and producer practices. Multivariate analysis and classification methods were applied to data from a full inventory of 80 orchards based on Mangifera indica samples (i.e., 41.8% of the total sample). Almost all orchards in the area are of traditional type with areas between 0.2 and 10.7 ha. These plantations are 30 years old on average and do not benefit from irrigation systems. The average density of plantations amounts to 32 Ind./ha. Plowing and weeding are the most frequent mechanical interviews. A total of 29 mango varieties were noted (including 24 local varieties). The area remains dominated by varieties such as Keitt (41.04%) and Kent (29.29%). The inventory of the fruit flora identified 48 species in 42 genera belonging to 29 families in all orchards. The Anacardiaceae family remains the most represented (48.28%). The typology allowed to define four groups of orchards.
