In case of dryland cultivation practices intelligently on need to minimize cost of production of any crop. Tillage is one of the major operations of the crop production and is an important contributor to the total cost of production. In this regards an experiment has been conducted on two tillage systemi.e. conventional and reduce tillage system in order to save the energy in production of wheat crop comprising three tillage treatments in combination to three doses of fertilizer application. The data revealed that the highest yield of wheat of 29.33q/ha was recorded in 50% conventional tillage + weedicide + interculture followed by conventional tillage + interculture with a grain yield of 27.87q/ha. With regard to nitrogen application through different sources, the highest average grain yield of 29.00q/ha was recorded with 100%N through inorganic fertilizer followed by 50% N through organic + 50% N through inorganic fertilizers with a grain yield of 28.25q/ha. As for as energy requirement and cost of operation were higher in the conventional tillage system (2907.53MJ and Rs.11347.33) than in reduce tillage i.e. 50% CT+ interculture+ weedicide (2227.20MJ and Rs.10335.30) and 50% CT+ interculture (2281.56 MJ and Rs.9948.60), respectively. The benefit cost ratio ranged from 1.08: 1 to 1.41: 1Keywords

Global climate change is the primary important factor for agricultural production and one of the most urgent environmental problems. Agricultural soil is dynamic biological system that both stores and releases greenhouse gases. This makes soils an important source of greenhouse gases but also a potential sink if right management is applied. Climate change mitigation impacts arise largely from the stabilisation of soil organic matter, the reduction in fertilizer requirements and gaseous emissions in soils, and the production of renewable energy which can displace fossil fuel consumption. Biochar application may improve the soil health and reduce emissions from biomass that would otherwise naturally degrade to greenhouse gases. Converting biomass to biochar offers an excellent method for reducing waste and using these byproducts
Biochar is one of the viable organic amendments to combat climate change and sustain the soil health with sustainable crop production. Biochar may be added to soils with the intention to improve soil functions and to reduce emissions from biomass that would otherwise naturally degrade to greenhouse gases. Biochar also has appreciable carbon sequestration value. Biochar application may improve the physical, chemical and biological properties of soils, reduce fertilizer requirements and stimulate plant growth, though the results vary between biochars, soil types and plant species. The effectiveness of biochar for the improvement of soil properties is influenced by the biomass feedstock and the pyrolysis conditions Biochar also has appreciable carbon sequestration value.

Role of soil carbon (C): Organic carbon is an important resource which is required to be managed and sustained in the soil for an efficient ecosystem functioning, and different SOC fractions depend on the agro technical managements. Soil carbon (C) is an important indicator of soil health and an integral part of the physical, chemical, and biological properties of the soil. Loss of soil carbon can lead to soil degradation and loss of productivity. Soil carbon is lost from the soil through erosion, residue removal, intensive tillage, and land-use changes. Carbon-enriched soil amendments, including animal manure, bio-solids, municipal compost, and biochar, among others, can restore soil productivity.- Biochar:A Boon for Vegetables

Biochar is the pyrolyzed product made by thermal degradation of organic materials in the absence of oxygen and is distinguished from charcoal by its use as a soil amendment. Over the past few years, much attention has received from researchers towards this pyrolyzed organic carbon because of the possible benefits arising to soil quality and crop yields. The idea to use biochar as an soil amendment comes from Amazonian terra preta soils. These soils are generally known for their high levels of fertility as compared to the adjacent soils where no organic C addition occurs.References
