Other claims from this paper (10)
- Intervention effect Organic fertilizer gave significantly lower red tomato yields than mineral fertilizer.
- Observation Organic fertilizer released nutrients more slowly than mineral fertilizer.
- Mechanism Organic fertilizer lowered leaf sulfur and phosphorus concentration, limiting tomato growth and yield.
- Association Fruit and leaf composition and taste tests gave no conclusive relation between sugar, acid, macronutrients and perceived taste.
- Intervention effect Mineral fertilizer produced higher fruit sugar content.
- Intervention effect Organic fertilizer produced higher fruit acid content.
- Observation Taste preference favored tomatoes given nitrate-dominated nutrient solution.
- Observation Taste preference also favored tomatoes given organic fertilizer with extra sulfur.
- Association Reduced tomato growth did not improve taste.
- Recommendation The authors conclude appropriate nutrient supply is crucial to obtain high yield and good taste.
