Biofertilizers as nutrient coextends of other sources for rainfed crops

Abstract

This article deals with microbial inoculants of N,-fixing bacteria, vesicular arbuscuJar mycorrhiwe (VAM), phosphate solubilizers and plant-growth promoting rhizobacteria (PGPR) and They, role in production of crops. Factors determining the success of inoculants technology along with a survey on their field performance are discussed. The rhizobial inoculants are deals in greater detail as a general example, and for the ether inoculants the discussion is restricted 10 the points which are specific to a particular group of inoculants. To popularize biofertilizers amongst farmers a holistic approach covering production of quality inoculants, selecting areas which need inoculationi, raining and educating extensionl staff . and appropriate crop management practices is suggested
