The experiment was conducted during 2011 to investigate the effects of organic fertilization on yield and
nutrient content of two saladette tomato genotypes grown in five media: S1 = sand + inorganic nutrient
solution; S2 = sand + vermicompost tea; S3 = mixture of sand: compost (ratio 1:1; v/v) + vermicompost
tea; S4 = mixture of sand: vermicompost (ratio 1:1; v/v) + vermicompost tea and S5 = mixture of sand:
compost: vermicompost (ratio 2:1:1; v/v) + vermicompost tea. The best four combinations were El Cid x S2, El Cid x S4, Cuauhtémoc x S2 and Cuauhtémoc x S5, which reached an average yield of 172.4 Mg ha-
1, the combination El Cid x S2 had the highest yield, wich was 184.7 Mg ha-1of fruit. In the El Cid x S2
and Cuauhtémoc x S2 combination were obtained medium sized fruit, while the El Cid x S3 and
Cuauhtémoc x S3 combination were obtained fruits with concentrations greater than 4.6 °Bx. The Zn content
was increased in the fruit harvested under organic substrates, while the Mn content was reduced
in them. The genotype Cuauhtémoc grown in S2 recorded the higher values in N, P and Zn contents. The
proposed treatments based on organic substrates without inorganic solution are viable alternative, because
the fruit quality is maintained and the organic products improve the production cost-benefits.
