The use of cow bone biochar for improving soil chemical properties and tomato quality and shelf life remains relatively unexplored. This study aimed to evaluate the effects of biochar on soil chemical properties, growth, yield, quality and shelf life of tomato. The experiment, conducted over a period of 120 days, comprised five levels (0, 10, 20, 30, and 40 t ha⁻¹) of cow bone biochar arranged in a completely randomised design replicated three times. Results indicated that cow bone biochar increased soil chemical properties, growth, yield, quality, shelf life and the percentage weight loss of tomato fruits relative to the control. The 40 t ha biochar level increased yield of tomato by 22%, 97%, 162 and 294%, respectively relative to 30 t ha, 20 t ha, 10 t ha and the control. Also, relative to 30, 20, 10 t ha biochar and control, application of biochar at 40 t ha increased shelf life of tomato by 12%, 23%, 28% and 70% respectively. These findings showed that biochar increases soil productivity, leading to improved tomato yield, quality, and shelf life. Further research is needed to determine if higher biochar rates can yield even greater benefits or if improvements level off beyond 40 t ha⁻¹.
牛骨生物炭在改善土壤化学性质、提高番茄品质和延长货架期方面的应用仍相对缺乏研究。本研究旨在评估生物炭对番茄土壤化学性质、生长、产量、品质和货架期的影响。该实验为期120天，采用完全随机设计，设置了五个水平（0、10、20、30和40 t ha⁻¹）的牛骨生物炭，重复三次。结果表明，与对照相比，牛骨生物炭提高了土壤化学性质、番茄的生长、产量、品质、货架期以及果实失重百分比。相对于30 t ha、20 t ha、10 t ha生物炭水平和对照，40 t ha生物炭水平使番茄产量分别提高了22%、97%、162%和294%。此外，相对于30、20、10 t ha生物炭水平和对照，40 t ha生物炭处理使番茄货架期分别延长了12%、23%、28%和70%。这些结果表明，生物炭提高了土壤生产力，从而提高了番茄产量、品质和货架期。需要进一步研究以确定更高的生物炭施用量是否能带来更大的益处，或者在超过40 t ha⁻¹后改善效果是否会趋于平稳。
