Abstract
This study discusses the effect of growth season and fertilization on quality characteristics of tomatoes. In a pot experiment, established in an unheated glasshouse, tomatoes were grown in two widely differing soils during two different seasons (winter and summer). Conventional fertilizers, applied in two doses, and corresponding slow-release fertilizers, applied in a single dose, were used. Summer fruits contained greater lycopene content and had a more reddish coloration than those harvested by the end of winter. Slow-release fertilizers further increased lycopene content compared to the conventional fertilizers. The widely different electrical conductivities between the two soils had no effect on the lycopene content. Fertilization contributed to an increase of soluble solid content (Brix) in fruits, but there was no difference among fertilizers used. Similarly, there was no significant response of pulp pH to growth season or fertilizer treatments.
