It is predicted that the world population will reach about 9.7 billion by the year 2050 and to feed this population the food production has to be increased proportionately. Further, climate which in turn results in abiotic stresses like drought, salinity, etc. seriously affect crop productivity. The present book brings out the role of different groups of microorganisms in alleviating abiotic stress in crop plants.
