The use of the popcorn at large scale determined us to study the Zea Mays hybrid Everta Perlat 625. There were administered various nitrogen and phosphorus doses in order to obtain significant results on the quantity and quality of the corn varieties used for popcorn and of course its grains expanding properties. In this paper there will be presented a series of significant results obtained through the use of various nitrogen and phosphorus in two important development stages, in two systems – irrigated and in natural conditions, cultivated on a silt-sandy soil determining as well its cultivation possibilities.
