Abstract
Two experiments on the lisianthus culture were conducted in ornamental plant growers property, in Brazil.
In the first experiment the physical characteristics suitable for the cultivation of this plant were evaluated and it was observed that treatments presenting 0.75 and 0.95 g cm-3 densities showed the best results for the evaluated parameters.
Lisianthus developed well in the following conditions: 72.60 to 75.10% porosity, 12.81 to 19.53% air space, 19.79 to 26.03% available water, 17.41 to 23.71% easily available water.
Different mixtures of materials, which had physical characteristics suitable for the culture, were analyzed in a second experiment and the cultivated peat + vermiculite; eucalyptus bark + conventional peat + sand substrates and control, presented the best results, showing good plant commercial quality.
Yet, the pine bark + earthworm humus substrate showed to be inadequate to lisianthus cultivation.
