These investigations were carried out in the 1981-1985 period in a stationary experiment founded in 1965/66, in rotational cropping of wheat, sugar beet and maize with accidental distribution and constant plots in 4 replications. The yield of the aboveground organs and parts, their chemical composition and removal of N, P O and K O by the yield was determined. It was found that there was a small dependence of the investigated sunflower properties on the intake of fertilizers but the dependence was great as regards meteorological conditions in some years.
