Experiment Title Effect of biochar and fertilizer levels on yield of kharif transplanted rice and its residual effect on rabi Indian bean
Research Type Departmental Research
Experiment Background Biochar, known as “Black Gold”, is a carbon-rich solid material derived from the thermochemical conversion of biomass (e.g., plant, manure, and sludge) under oxygen limitation. It has been shown by numerous studies that biochar is used as a novel approach with potential benefits to agriculture and the environment. After pyrolysis, biochar became more hydrophobic and recalcitrant due to the formation of aromatic structures, and a negative emission potential of biochar. Earlier published reviews on biochar included a summary of the negative effects of biochar addition on soil physicochemical properties (e.g., pH, soil bulk density, soil porosity, and organic matter). Biochar amendment has been reported to positively influence soil C stability, especially for soil that lacks organic matter. Biochar acts, therefore, as an emerging and attractive option to effectively improve fertilizer utilization performance. Biochars may enhance roots to take up more cations, such as K+, Ca2+, and Mg2+ from soils, resulting in the release of H+ to balance the charge in rhizosphere. Meta-analysis studies have suggested that the addition of biochar to flooded soils and/or acidic soils during flooded periods as part of a management regime can significantly reduce the CH4. With the information on beneficial effect of biochars in rice, the present experiment has been proposed.
