All plants need the right amount of light, water, nutrients, and space in order to survive. Seed plants also need to be pollinated and produce seeds. The seeds must germinate at the right time in a place that will supply all their needs. More and more food is needed all over the world in order to meet rapidly growing population demands, while the modern agriculture on increasing output has already reached its limit. It is badly in need to cultivate new crop varieties for increase the yield and resistant to environmental stress and insects. However, crops are still need to provide the necessary fertilizer nutrients which is insufficient in soil. Recently, many evidences showed that soil microbes provide an opportunity for reducing agricultural demand in inorganic fertilizer. Microorganisms, due to their huge gene pool, are also used for a potential resource in biochemical reactions, which recycle nutrients for plant growth. Therefore, we need to modify and better use of soil microbiota to promote plant growth. The main aim of the study isolation of plant growth promoting microbes from Arachis hypogaea peanut (Fabaceae) and their effect on plants such as Sorghum bicolor solam (poales).
