- Intervention effect Poultry manure increased tomato fruit yield by 83.4% versus biochar.
- Intervention effect Poultry manure increased tomato fruit yield by 382.5% versus the control.
- Intervention effect Calcium sulfate reduced tomato weight loss by 24.81%, 55.59%, 61.19% and 104.99% relative to calcium nitrate, poultry manure, biochar and control, respectively.
- Intervention effect Calcium sulfate increased tomato shelf life by 14.78%, 29.79%, 36.42% and 69.44% relative to calcium nitrate, poultry manure, biochar and control, respectively.
- Mechanism The authors attributed calcium sulfate’s shelf-life effect to its high calcium content.
- Recommendation The authors recommend studying poultry manure combined with calcium sulfate for tomato yield, quality and shelf life.
