The content of potassium, phosphorus, calcium, magnesium, zinc and copper was determined in the fruit. The lack of any single nutrient produced a greater effect in experiment 1 where the diversified mineral fertilization was established in 1923. Potassium-nitrogen fertilization positively affected zinc and copper content in experiment 1 whereas in experiment 2 it had a negative effect on zinc content. Liming significantly decreased the amount of all mineral constituents except calcium. (Author)
