Effect of Environmental Stress on Vigna Mungo in Different Soil

Bifertilizer play a very significant role in improving soil fertility by fixing atmospheric nitrogen by in association with plant roots and without it solubilize insoluble soil phosphate and produces plant growth substance in the soil. They are in fact being promoted to harvest the naturally available biological system of nutrient mobilization Soil-plant-microbe interaction has got much importance in recent decades. Many types of microorganisms are known to inhabit soil especially rhizosphere and play important role in plant growth and development. Indiscriminate use of synthetic fertilizers has led to the pollution and contamination of the soil has polluted water basins destroyed microorganism and friendly insects making the crop more prone to diseases and reduced fertility. Demand is much higher than the availability. Depleting feedstock/fossil fuels (energy crisis) and increasing of fertilizers. This is becoming unaffordable by small and marginal farmers.
