The micro-organisms with the aim of improving nutrients availability for plants is an important practice and necessary for agriculture. During the past couple of decades, plant growth-promoting rhizobacteria (PGPR) will begin to replace the use of chemicals in agriculture, horticulture, silviculture, and environmental cleanup strategies. Scientific researches involve multidisciplinary approaches to understand adaptation of PGPR, effects on plant physiology and growth, induced systemic resistance, biocontrol of plant pathogens and biofertilization. This is due to the emerging demand for dependence diminishing of synthetic chemical products, to the growing necessity of sustainable agriculture within a holistic vision of development and to focalize environmental protection. The PGPR are naturally occurring soil bacteria that aggressively colonize plant ischolar_mains and benefit plants by providing growth promotion.- Stabilising Farm Income of Indian Farmers

In an agrarian county like India agriculture is the back bone as farming is the major occupation of its livelihood, likewise income from agriculture is the major player in economic development. With gamble of climate the population getting involved in the backbone is showing a negative trend ultimately showing a ghastly rise in unemployment. With this background it becomes imperative to give a stabilized and profitable income source from agriculture. When all the possible alternatives are dug in one thing can be noticed that increase in income due to increase in production has already reached a plateau where no further increase can be expected. Then all the possible alternatives needs to be explored focussing on decreasing cost of cultivation and increasein value addition chain for better marketability.- Effect of Biochar on Soil Fertility and Carbon Sequestration

Every year worldwide anthropogenic CO2 emissions from energy generation is increasing. By 2020, 33.8 billionmetric tons per year could be emitted, up from 29.7 billion metric tons per year in 2007.Added to anthropogenic CO2 emissions,the natural carbon cycle and deforestation. Research to mitigate CO2 emissions, reduce the CO2 atmospheric concentration, and enhance soil fertility, crop production and bioderived energy production would be welcome. Efforts to reduce CO2 emissions through carbon sequestration include both reforestation and CO2 injection into underground saline and other geological formations or into the deep ocean. Sequestering C in soils as biochar can improve soil fertility, supplementing adding biosolids, organic waste fertilizers and improving crop rotation. However, organic wastes and biosolids will decompose in the soil emitting CO2.Conversely, the carbon in biochars, originally removed from the atmosphere as CO2 during plant growth, persist in soils from decades to millennia. Thus, if biochar application proves widely applicable at low cost in improving soil fertility in agriculture, its widespread use could lead to enhanced carbon sequestration. Biochar can be made either as a byproduct of fast pyrolysis to generate biooil (a liquid fuel precursor) or slow pyrolysis. Biochar production technologies 26 and CO2 capture, storage and utilization.References
