Nyù is the main morphotype of yams of Passoré. It is generally cultivated without chemical fertilizer.
The study aims to determine the effect of one rate of chemical fertilizers on the yield of yams « nyù »
of Passoré in farmers’ environment of Burkina Faso and to collect the appreciations of the various
actors about tubers in the production chain. The results reveal that chemical fertilizer involved a better
expression of the agro-morphological parameters and an increase of the tubers yield which reaches
42.5 t / ha compared to the field not fertilized where tuber yield is slow (9 t / ha). However, tubers obtained
of treated field have not a good organoleptic quality whereas the tubers of untreated fields have good
taste. Moreover, the chemical fertilizer changed also the morphology, taste and consistency of the
tubers. These results could help all actors to choose the best method of nyù production according to
their objectives. |
