Other claims from this paper (8)
- Intervention effect Potassium and phosphorus fertigation significantly raised the soil concentration of these two nutrients.
- Observation The nutrient concentration rise was greater in the 0-30 cm soil layer than in the 30-60 cm layer.
- Intervention effect Phosphorus fertigation raised leaf P significantly and steadily.
- Intervention effect Phosphorus fertigation raised fruit P significantly in one year.
- Intervention effect Phosphorus fertigation raised the yield in the last three years by 30% (p=0.084).
- Intervention effect Fruit size was not affected by N, P, or K nutrition.
- Observation The threshold concentration of P in 10-week-old mid-shoot leaves for leaf analysis of Spadona pear was found to be 0.14%.
- Observation The optimal concentration of P in 10-week-old mid-shoot leaves for leaf analysis of Spadona pear was found to be 0.15%.
