NUTRITIONAL ANALYSIS AND CORN PRODUCTION DUE TO APPLICATION OF DOMESTIC SEWAGE SLUDGE

In order to evaluate the yield and nutrition in maize plants due to application of sewage sludge from the sewage station in the city of Jeronimo Monteiro was mounted an experiment in completely randomized design with three treatments and five replications. The treatments in mineral fertilizers, use of sewage sludge equivalent to nitrogen recommended for the cultivation and application of sewage sludge with total mineral fertilizer. At the end of the experiment the seeds were weighed while the nutritional analysis was done at flowering and the results showed that application of sewage sludge increased the weight of seeds per pot and foliar concentrations of nitrogen, phosphorus, potassium , calcium, magnesium, sulfur, zinc, manganese, copper and boron and copper in maize. On the other hand the others nutrients did not change significantly.
