The impact of culture system and fertilization type on yield and fruit quality of greenhouse tomatoes

This paper presents the results of research regarding the influence of some technologicalinputs on greenhouse tomatoes yield and fruit quality. In order to establish how the fertilization andsystem of culture can influence the greenhouse tomatoes yield and quality, two systems of culture (insoil and in organic substrate) and different types of fertilization (basic and additional) were analyzed.Maximum early and total yields were obtained in case of organic substrate culture. Vitamin C, acidity andtotal sugar content of fruit increased with radicular+foliar additional fertilization. None of the nitratevalues over passed the accepted limits of permission for greenhouse tomatoes.
