ABSTRACT: With an overall contribution of nearly 4 billion CFA
francs to Senegal’s income, providing 23,000 employments more than 50% are women in 2021, the
mango sector has shown its importance in the Senegalese economy even if the
potential remains largely under-exploited. Thus, the study on the main local
varieties remains an important perspective. This work carried out in the farm
of the agroforestry department concerns the growth and development of four
varieties (Pince, Kouloubadaseky, Sierra Leone and Diourou) on different soils
(Mangifera indica, Anacardium occidentale and Khaya senegalensis). This work aims to contribute to the knowledge of
the most cultivated varieties in Casamance. It is also a question of seeing the
response of these varieties to grafting with the Kent variety. An experiment
was conducted for one year with a split plot design consisting of 4 replicates
(blocks). Each block contains 4 plots and each plot contains 3 sub-plots with
20 plants each. The parameters measured were: diameter at the collar, height,
number of leaves, biomass, number of growth units and grafting success rate.
The Sierra Leone variety showed the best growth results in terms of diameter at
the crown (0.511 ± 0.090), leaf production (16 ± 2.52) and dry biomass (28.67 ±
16.80). The Kouloubadaseky variety had the best height record (41.90 ± 6.15) and
the Diourou variety gave the best results in terms of fresh biomass (68.94 ± 30.90), number of growth units (9.350 ± 2.06) and
grafting success rate (78.84% ± 29.44%). Anacardium occidentale soil substrate
gave the best growth in height (39.73 ± 5.54 cm) while the substrate collected
under M. indica L
produced a greater number of leaves (13.14 ± 3.64) and grafting success rate
(71.12% ± 37.25%). The Khaya senegalensis substrate recorded the highest values in biomass production (61.00 ± 35.93 for
fresh biomass and 25.25% ± 15.74% for dry biomass).
