Abstract
The keeping quality of tomatoes harvested in spring and early summer was better than that of tomatoes harvested in autumn.
The content of potassium was highest in the yield from the first clusters, and it decreased during the remainder of the harvesting season.
The correlation between the potassium content and the storage loss was clearly negative.
The keeping quality of fruits was not promoted by the increase of dry matter.
The content of potassium was highest in the yield from the first clusters, and it decreased during the remainder of the harvesting season.
The correlation between the potassium content and the storage loss was clearly negative.
The keeping quality of fruits was not promoted by the increase of dry matter.
When tomatoes were grown in basin peat culture the ratio of nitrogen to potassium in the liquid fertilizer had a clear influence on the content of dry matter, soluble dry matter and 
-carotene of the fruits and their keeping quality.
The storage losses were greatest when the ratio of N to K in the liquid fertilizer was 1:1. The keeping quality was best when the ratio was 1:2.
