EFFECT OF NUTRIENT SUPPLY ON FROST HARDINESS AND FRUIT SET OF SOUR CHERRY FLOWERS AND ON YIELD |
| Author: | E. Szücs |
| Abstract:
Nitrogen and phosphorus had only small effects on leaf nutrient content. Potassium fertilization was positively correlated with leaf-K content and negatively related to leaf-Mg. Nitrogen and potassium fertilization had a favourable effect on fruit set, but yield was increased only by potassium. Positive effects of K and slightly negative effects of N on the frost hardiness of flowers were shown in the orchard and also in a controlled climate chamber. Microclimate had a stronger effect on frost damage of the flowers than did the nutrient supply. | |
