Abstract:
The challenge in food security is important for rice in west Africa. As well, this study on the use
of mycorrhizal inoculants in rice field, is a contribution to improving rice yields by biological
fertilization. Incidence of intake of a mycorrhizal inoculant is compared to mineral fertilization,
through growth and development parameters of upland rice, on ferralsol in West part of Cote
d'Ivoire. Experimental design is a Fisher Block with six replications. In order to assess the
efficiency of these two fertilization methods, an unfertilized treatment was integrated in the
experimen. The symbiotic association (mycorrhizal-rice) has contributed to improve tillering
(147.5 tillers/m^2) and yield (1.62 tha-1
) in reference to unfertilized control (126.2 tillers/m^2 and
1.44 tha-1
). Yields are better as mycorrhizae are combined with mineral fertilizers for a gain of
64% in terms of paddy yields. In short, mycorrhization appears to be a powerful biological tool
for optimizing sustainable soil management and rice yields. |
