Abstract
The economic development of Côte d'Ivoire largely depends on
agriculture with industrial crops in the first rank. However, with the global
inflation, several countries including Côte d'Ivoire have found important to
diversify their agricultural resources. Thus, sesame could present itself as an
alternative to fight against malnutrition in low-income areas. Its seeds, rich
in vitamins, contain nutrients able to compensate the nutritional deficiencies
for humans. Unfortunately, there is no documentation about this crop in Côte
d'Ivoire. Our study is one of the first in Côte d'Ivoire to assess the
contribution of bees in sesame production improvement. It was carried out at
the Botanical garden of Peleforo Gon Coulibaly University of Korhogo. Nine
varieties of sesame were grown but only, five varieties germinated and were
used for experimentation. The methodology consisted to apply three pollination
treatments (control, cross-pollination, self-pollination) each, on different
flowers of each variety. At the maturation, for each variety, it was noted
whether the experimental flowers produced fruits or not. In case of fruit
production, fruit weight, number of seeds and seed weight were measured. The
results showed that cross-pollination significantly increases production
parameters regardless of the variety. Alone, the honey bee presented the best
performances on the production parameters of the five varieties of sesame.
However, for the variety SI 099, the effect of cross-pollination was more
accentuated. The findings highlight potential negative consequences of bees
decline on crop yields in sub-Saharan Africa. They also make it possible to
guide farmers' choice towards the varieties of sesame for which, the impact of
pollinators could be considerable on the production.
