Abstract
La faible disponibilité du phosphore dans le sol est une contrainte majeure et fréquente dans le monde entier affectant considérablement le rendement agricole. Bien que l’utilisation des engrais chimiques a augmenté le rendement, mais en contrepartie elle a fragilisé les sols et pollue les écosystèmes. Dans le sol, le phosphore réagit facilement avec des ions positivement chargés comme le calcium, le fer et l'aluminium pour former des substances relativement insolubles. Le phosphore devient complexe et non absorbé par les racines des plantes même dans le cas de l’utilisation d’engrais phosphatés. De ce fait, il est devenu indispensable de trouver des solutions alternatives tout en conservant une meilleure production agricole. L’utilisation de microorganismes symbiotiques (produits "bio") est évidente et va s’imposer de plus en plus dans le secteur agricole vu les exigences et les tendances des marchés mondiaux. Les bactéries autochtones du sol, solubilisant les phosphates complexes, sont considérées comme une solution plus écologique à une telle problématique, du fait qu’elles peuvent mobiliser le phosphate présent naturellement dans le sol, ou apporté par les engrais phosphatés, par différents mécanismes et mettre ainsi le phosphore à la disposition de la plante. Elles peuvent également jouer un rôle très important en tant que rhizobactéries favorisant la croissance des plantes (plant growth promoting rhizobacteria). L’introduction de souches importées de l’étranger "exogènes" pose un problème d’adaptation dans les écosystèmes marocains et de maintien de la biodiversité. La présente invention vise à proposer un bioinoculum à base de deux souches marocaines ayant une grande capacité à solubiliser différentes formes de phosphore complexe. En plus, elles favorisent la croissance des plantes via la production d’auxine, de sidérophores et d’exopolysaccharides. Les souches solubilisant le phosphate ont été appliquées sous la forme d'une suspension liquide à la concentration de l’ordre de 109 ufc/ml pour chacune des deux souches. Les graines de v. Faba ont été restées au contact des souches bactériennes pendant 30 min à l’obscurité. Une deuxième inoculation a été appliquée aux racines des plantules après une semaine de mise en culture des graines. L'effet de ces souches sur la rétention de phosphate par la plante légumineuse v. Faba a été également évalué. L’inoculation mixte par ces deux souches a augmenté significativement le rendement agricole et la nutrition phosphatée de v. Faba.The low availability of phosphorus in the soil is a major and frequent constraint all over the world considerably affecting agricultural yield. Although the use of chemical fertilizers has increased the yield, but in return it has weakened soils and polluted ecosystems. In soil, phosphorus readily reacts with positively charged ions such as calcium, iron, and aluminum to form relatively insoluble substances. Phosphorus becomes complex and not absorbed by plant roots even with the use of phosphate fertilizers. As a result, it has become essential to find alternative solutions while maintaining better agricultural production. The use of symbiotic microorganisms ("organic" products) is evident and will become more and more prevalent in the agricultural sector given the demands and trends of global markets. Native soil bacteria, solubilizing complex phosphates, are considered to be a more ecological solution to such a problem, because they can mobilize the phosphate naturally present in the soil, or provided by phosphate fertilizers, by different mechanisms and put thus phosphorus available to the plant. They can also play a very important role as rhizobacteria promoting plant growth (plant growth promoting rhizobacteria). The introduction of strains imported from abroad "exogenous" poses a problem of adaptation in Moroccan ecosystems and maintenance of biodiversity. The present invention aims to provide a bioinoculum based on two Moroccan strains having a great capacity to solubilize different forms of complex phosphorus. In addition, they promote plant growth through the production of auxin, siderophores and exopolysaccharides. The phosphate solubilizing strains were applied as a liquid suspension at a concentration of about 109 cfu / ml for each of the two strains. The seeds of v. Faba were left in contact with the bacterial strains for 30 min in the dark. A second inoculation was applied to the roots of the seedlings after one week of cultivation of the seeds. The effect of these strains on the retention of phosphate by the leguminous plant v. Faba was also evaluated. Mixed inoculation with these two strains significantly increased crop yield and phosphate nutrition of v. Faba.
