Physiological proprieties from corn influenced by the differentiate application of nitrogen and phosphorus

The paper enumerates several physiological processes that take place at the Campion corn hybrid and the interaction between the hybrid in the irrigated and un-irrigated culture, as well as the appliance of NP fertilizers. To obtain performances at this type of corn culture, soil analyses were made before the establishment of experimental parcels and it was aimed the moment when the corn plants had already formed eight leaves to emphasize the results better. The determinations and the laboratory analyses emphasizes the most important physiological processes from plant life, where the water and fertilizer dosages had a crucial role in obtain of positive results.
