This thesis focuses on how Integrated Nutrient Management strategic approaches affect Green House gas emissions especially methane (CH₄) flux in Hybrid Sorghum production. Field trials were conducted in 2024, employing six different treatments: There five treatments namely: Control (labelled as 0 N), 100% Soil Test Based Fertilizer (STBF), Sole Biological Consortia (Prerak), 50% STBF + Biochar and sole Biochar + Biological Consortia. The treatments were laid down using a randomized block design which was replicated three times. Performance showed that the 100 per cent STBF treatment provided the highest methane emission, approximately 450 g/ha due to constant nitrogen ion input to microbial activities. However, this site and the control treatment emitted approximately 150 g/ha of methane which shows the need to improve soil structure through biochar addition. Further, the synergy treatment showed moderate emission levels and indicated that nutrient inputs affected microbial responses. In line with this research, there is a need to find ways of improving nutrient management in order to reduce GHGs without compromising yields of crops so as to provide significant information towards sustainable agricultural practices
