Abstract
Anacardium
occidentale
L. is a plant of great economic importance, but its cultivation is confronted
with problems of infection, growth and development due to the poor quality of
the seeds, which are affected by fungal diseases that lead to crop losses. The
objective of this study is to improve cashew nut production by treating the
seeds with plant extracts before sowing. To achieve this objective, cashew
seeds accessions in Cameroon and Chad were soaked in extracts of Azadirachta indica, Calotropis procera and Cassia
occidentalis for 12 hours for treatment. These seeds were sown in pots
containing black soil and sand as substrate to collect data on germination
percentage, infection percentage and growth parameters (colar diameter, height,
number of leaves, seedling vigour and plant vigour). The results showed that
the seeds of the of the Koumra and Garoua accessions treated with A. indica extract at all concentrations
showed 100 % germination and 0 % infection. Similarly, all seedlings from the
seeds treated with the different plant extracts showed significantly higher
crown diameters, heights, number of leaves and seedling vigour than seedlings
from non-treated seeds. These results suggest the use of these plant extracts
to reduce cashew seed infections and to enhance seed germination and seedling
vigour.
