ABSTRACT
The system of rice intensification (SRI) is an agroecological approach to rice cultivation that seeks to create optimal conditions for healthy plant growth by minimizing inter-plant competition, transplanting widely spaced young single seedlings, and optimizing favorable soil conditions with organic amendments, increased soil aeration by weeding, and controlled water management. These practices improve rice plant growth with yields up to three times more than with conventional cultivation methods, and increase crop resilience under biotic and abiotic stresses. This review discusses the roles of beneficial microbes in improving rice plant growth, yield, and resilience when SRI practices are used, and how these modifications in plant, soil, water, and nutrient management affect the populations and diversity of soil microorganisms. Mechanisms whereby symbiotic microbes support rice plants' growth and performance are also discussed.
