The corelation between the doses of nitrogen and phosphorus appliend on the non irigated system and physiological processes of the crop hybrid Campion – year 2012

The paper purposes to follow the supply of corn plant with a nitrogen and phosphorus supplement in different quantities in two systems: irrigated and un-irrigated. The most important physiological processes that take place in plant life were followed also and from these there were chosen to be studied: photosynthesis, respiration, absorption capacity and suction force. Mathematical calculus was made to interpret the results, taking into account the variance analysis which represents only a first important phase of systematization of information. The conclusions formulated show the necessity of irrigated system collaborating with fertilizer appliance to obtain larger crops and healthier plants.
