Soil microbes are the part and parcel of low-nutrient-input sustainable agriculture around the globe, especially under various biotic and abiotic stresses. In view of the rapid mining of phosphate reserves and the scorching prices of phosphatic fertilizers, this first-ever study highlights the comparative role of ACC-deaminase, phosphate-solubilizing Pseudomonas fluorescens and mycorrhizal fungus Glomus mosseae in improving the growth and yield of mungbean (Vigna radiata L.) under phosphorus deficiency stress.
