COSTA, Zailton Vagner Barreto da et al. Effect of primary sewage application on corn production at the settlement of Milagres (Apodi-RN). Rev. Ambient. Água [online]. 2014, vol.9, n.4, pp.737-751. ISSN 1980-993X.

The application of treated domestic wastewater is an effective way to control environmental pollution, and is a viable option for increasing water availability in arid and semiarid regions. This study analyzed the production of maize (Zea mays L) fertilized with primary sewage at the rural settlement of Milagres in Apodi-RN. The study evaluated the following characteristics of maize: plant height, stem diameter, number of leaves, average ear weight with and without straw, wet and dry grain weight. The study found that fertigation with primary sewage resulted in higher values of plant height (PH), stem diameter, number of leaves, husked ear weight, ear weight without straw, wet weight of grains, dry weight of grains and grain yield compared to the same characteristics when artesian well water was used. Domestic sewage provides a source of nutrients for agricultural production.
