Abstract

There are several aspirations to model the soil-plant-atmosphere system. They are different efforts according to the order of magnitude of resolution of physical and physiological processes and requirements of computer technique. Our main purpose was to build up a corn model using a personal computer. Because of the importance of maize /Zea mays L./ in Hungary the model was fitted and tested by maize data /c.v. SZTC-255/ derived from the Agrometeorological Research Station at Keszthely /46°44′N; 17°15′E/. The model is based on the Sirotenko model [1], but it is a simpler one.
