Abstract

The aim of the study was to determine the effect of urea and nitrate forms of nitrogen on the yield and fruit quality of greenhouse tomato grown using NFT. The results showed no effect of the form of nitrogen on total fruit yield either in the spring or autumn. Also the form of nitrogen had no significant effect on dry matter, sugars, ascorbic acid, or organic acids content in the fruit. However, in the autumn fruits from plants fertilized with urea had a higher dry matter content than those treated with the nitrate form. At the same time, a slight effect of the nitrogen form on the content of some minerals (N, P, Ca, Mg) in the tomato was observed. These suggest that urea may be used as a nitrogen source for tomato grown with NFT.
