A biofertilizer is a substance which contains living microorganisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the anterior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant or bio-fertilizer contains biological means, living organisms that synthesis the atmospheric plant nutrient in the soil or in the plant body, or create such an atmosphere in the soil or in the medium in which the organisms are kept. Biofertilizers are applied as seedling root dip, seed or soil treatments. Many researches showed that the growth, yield and quality parameters of certain plants significantly increased with biofertilizers containing bacterial nitrogen fixer, phosphate and potassium solubilizing bacteria and microbial strains of some bacteria. These bacteria reduced the population of Meloidogyne incognita infecting chilli and tomato and Tylenchulus semipenetrans on Washington navel orange. Also, Six new commercial Egyptian bio-fertilizers viz.,nitrobien, rizobacterin, cerealin, phosphorine, microbien, blue green algae, and five new commercial Egyptian plant nutrients viz., nuftarein, potassein F, citrein, kotangein and kapronite as for the control of root-knot nematode, Meloidogyne incognita on sunflower. All the tested products significantly reduced the numbers of juveniles in soil, and galls, females, eggmasses on roots. Also, nitrobien and phosphorine were effective in reducing M. incognita population infecting cowpea and enhancing plant growth criteria.
