SULPHUR CALCIUM AND MAGNESIUM IN PROCESSING TOMATOES GROWN IN SUB-ALKALINE OR SUB-ACID SOILS
The results of the first trial revealed significant effects of sulphur on marketable yield, ripening concentration and soluble solid content. A significant interaction between sulphur and the other elements was also detected, with positive effects on marketable yield and the soluble solids produced per unit area. Furthermore, the sulphur and phosphorus interaction resulted in a more concentrated maturity period and a higher soluble solid content.
The second trial demonstrated that the calcium — magnesium applications, regardless of the type of administration, increased the total production and the soluble solids. In the second year, the combination of these two elements also had a positive effect on marketable yield and the ripening concentrated period.
Unlike the reports of other authors, calcium did not have any effect on blossom-end rot.
