Abstract

The use of sewage sludge in plant production has been a promising alternative due to the high concentrations of organic matter and nutrients present in this biosolid. The objective of this work was to evaluate the effect of different proportions of organic compound containing sewage sludge on the substrate composition for the initial development of corn plants in greenhouse. The treatments consisted of composting (composed of sewage sludge and urban pruning residue) mixed with different proportions of commercial substrate. The addition of sewage sludge in the substrate improved the development of corn plants, evaluated by dry matter production of shoot and root, plant height, leaf number, stem diameter, root development and photosynthetic pigment production. This higher development of the plants was directly correlated with the higher levels of N, Ca and Mg accumulated in the plants.
