Innovative technologies using biochar were certified to mitigate the impacts of climate change and soil degradation on agriculture and ensure food security. An experiment was carried out in 2022 & 2023 cropping seasons to evaluate the effectiveness of biochar application rates at 10 t/ha, 7.5 t/ha, and 5 t/ha on soil properties and yield parameters of tomato varieties. The experiment was laid out in a RCBD replicated three times. The results show that application at 10 t/ha improved and increased pH, organic carbon, total N, and available P and K. Maximum fruit number/ha (686.2) and harvest weight (3452kg) were recorded at 7.5kg/ha. In comparison, 10 t/ha had the maximum biomass (dry weight) and harvest index compared to those of the control. The rate of 7.5 kg/ha of biochar could improve the yield, nutrient efficiency, and economic benefits of open-field tomato plants. It could be recommended for managing agricultural production.
