abstract:
Tomatoes were grown in coconut fibre using nutrients with a differentiated content
of N and K. The nutrient solutions did not affect significantly the nutritional status of plants.
This regularity referred both to the macro- and micro-elements. However, the grown cherry tomato
cultivars differed by their component content in the index parts of the plants. The greatest amounts
of nitrogen, phosphorus, potassium, calcium, magnesium and copper were usually found in leaves of
„Flavorino” cultivar, on the other hand, the greatest amounts of sulphur, sodium, manganese, zinc
and boron were identified in „Conchita” cultivar. The critical values and guide values elaborated for
standard tomato cultivars have proven to be useless for the estimation of the nutritional status of
cherry tomato cultivars. It is recommended to continue further studies in order to permit modification
of the present index values or to elaborate new ones for the discussed group of cultivars.
