Abstract:
Salinization is recognized as the main threats to environmental resources and human health in many countries, affecting almost 1 billion worldwide/ globally representing about 7% of earth’s continental extent. It has been estimated that an approximate area of 7 million hectares of land is covered by saline soil in India. Agricultural crops exhibit a spectrum of responses under salt stress. The impacts of salinity include low agricultural productivity, low economic returns and soil erosions. Soil salinity imposes ion toxicity, osmotic stress, nutrient (N, Ca, K, P, Fe, Zn) deficiency and oxidative stress on phosphorous uptake from soil. In order to access the tolerance of plants to salinity stress, growth or survival of the plants, alleviation of abiotic stress is can be done by rhizosphere bacteria. Studies on these shown that inoculations with selected PGPR and other microbes could serve as the potential tool for alleviating salinity stress in salt sensitive crops. It can be useful in developing strategies to facilitate sustainable agriculture in saline soils.
