SUMMARY

Two experiments were conducted to compare the effects of ammonium sulphate and anhydrous ammonia in corn production. One experiment was made in Latosolic B Terra Roxa, at the Campinas Experiment Center and the other in Podzolic Soil on Calcareous Sandstone of the Marília variation, at the Pindorama Experiment Station.

All treatments received phosphorus and potassium and the nitrogen was applied as ammonium sulphate and anhydrous ammonia at rates of 60 kg/ha of nitrogen.

The results showed that in Campinas there was no difference between the check and the treatment with anhydrous ammonia. Only ammonium sulphate showed a difference of statistical significance. In Pindorama there was no difference among the treatments.
