Tests were done during the years 1980-82 on light soil (light loamy sand) of a good rye complex after potatoes. The cultivation of grain corn was tested in 3 years rotation using 2 plant densities 6 and 8 plant/sq. m and with the use of N in few plant development stages. The highest quantity (6.98 t/ha) was obtained by using 150 kg/ha in the phase of 4-5 leaves and by using a 75 kg/ha dose before sowing and 75 kg/ha in the stage of tassel appearance (6.83 t/ha) no significant differences. The density of 8 plants /sq. m proved to be more effective because the obtained yield was 6.97 t/ha and with lower density was 6.15 t/ha. Protein yield in kg and the number of oat units per ha were similar and dependent on the yield quantity of the nitrogen content and the course of weather during the years
