Other claims from this paper (12)
- Intervention effect The numbers of flowers and of marketable fruits per plant increased with nitrogen concentration.
- Intervention effect Mean fruit weight and total yield increased with nitrogen concentration.
- Intervention effect Low nitrogen levels delayed harvesting.
- Intervention effect The proportion of unevenly ripened fruit decreased with increasing concentrations of both N and K.
- Intervention effect High potassium decreased the percentage of hollow fruits.
- Intervention effect The percentage of hollow fruits increased with nitrogen concentration.
- Intervention effect Titratable acidity of the fruit juices increased significantly with nitrogen concentration (P<0.001).
- Intervention effect Titratable acidity of the fruit juices was little affected by potassium treatment.
- Intervention effect The nitrogen concentration of the nutrient solution largely controlled the percentage of K in the leaves and the total K uptake.
- Mechanism The unexpected nitrogen effects on leaf K and K uptake were attributed to growth stimulation by N, increasing water requirement and hence the application of N and K by the sub-irrigation system.
- Intervention effect The highest yields and best quality fruit were obtained with 250 ppm N and 400 ppm K in the solution.
- Recommendation Lower concentrations of K might be preferable after continued cropping in the same compost.
