Production of biostimulant based on arbuscular mycorrhizal fungi

Abstract

In Benin, the majority of cultivated land, especially that of maize cultivation, shows symptoms of degradation with differences from one area and locality to another. In such a context, maize productivity will have to be based on the use of soil conservation techniques and soil fertility. Soil-dwelling organisms have the power to promote plant growth through -i- the improvement of plant nutrition (nitrogen fixation, phosphate solubilization, iron chelation), -ii- the production of plant growth hormones and -iii- the production of antibiotics that ensure the protection of plants against soil pathogens.
Arbuscular mycorrhizal fungi produce spores or propagules (inoculum) that promote good plant development and an increase in yields with a reduction in the quantities of mineral fertilizers, especially phosphate fertilizers according to the results of experiments
