Effects of Soil Application of Biochar on Soil Health and Productivity of Rice-Wheat Cropping System in Rohtas District of Bihar

Due to migration of work force from agriculture it became inevitable to adopt farm mechanization to ensure food supply to growing population. Mechanization leads to crop residue burning in open field for rapid clearing of field and sowing of new crop. Crop residue burning in open field became one of the most sever environmental and social problem form sustainable agriculture production and human survival. Conversion of crop residue into biochar and its use in agriculture is a healthy option for its mitigation. Present study was focused to assess the effect of biochar on sustainability of rice-wheat productivity in Rohtas district of Bihar. The results showed that the no significant change was observed in system productivity but soil health was improved significantly. Advancing in sowing time of Rabi crops and reduced weed density ensures the better future of biochar use in agriculture.
