The trial was carried out at the Universidade Estadual de São Paulo, in Botucatu (Brazil), to determine the best substrate and to evaluate the nutritive solution in cucumber seedlings production. The experimental design consisted of randomized complete block design, with four replications. The twelve treatments consisted of six substrates and two management forms (water floating and nutrition solution floating). The substrates were vermiculite, carbonized rice straw and not carbonized, carbonized rice straw + not carbonized rice straw, vermicullite + rice straw without carbonized and substrate prepared with soil mixture. The best treatment was substrate with soil mixture in nutritive solution.
