A field experiment was conducted between 2013-2014 in order to establish the influence of organic fertilization on the vegetative behaviour and productivity of greenhouse eggplant, Traviata variety, in conditions of conversion to biological production. Several variants were tested: N24P12K12+Wuxal Macromix, Arcobaleno Super+Hemozym+Amino Total, Italpolina+Biorex+Duetto+Guanito+Biofa, Naturale+Osmo+Nutri Algafid. Best vegetative characteristics had variants fertilized with Italpolina+Biorex+Duetto+Guanito+Biofa by mass fruiting values compared to the control were 115.87% for the mass of branches, 105.38% for the number of leaves, 146.19 to fresh mass of the leaves, 127.15% for the mass of fruits, 131.44% for fresh mass of the whole plant. The highest yield and total yield form plants grown after organic fertilization with Naturale+Osmo+Nutri Algafid, respectively 455.55 and 2049.44 kg / da. The results obtained showed that the Naturale+Osmo+Nutri Algafid is the most suitable for bioproduction of greenhouse eggplant.
