Abstrakt:

The results of three-year investigations with cv. Galaxy F1 cabbage grown commerciallyin an important agricultural region of South Poland are presented. The effect of therate of ammonium sulphate and UAN (solution of ammonium nitrate + urea), the methodof application (placement and broadcast technique) and foliar fertilization (urea and SupervitK) on Cu, Mn, Zn, Fe, B and Mo concentrations in edible parts of cabbage were surveyed.Nitrogen fertilizer was applied at the rate of 120 kg N ha–1. With the placementfertilization method, fertilizer was applied in rows 10 cm deep and 10 cm away from eachplant when seedlings were transplanted. Foliar sprayings started at the beginning of intensiveleaf growth and continued during the growing season at two-week interval. Thefoliar nutrition with 2% urea was carried out 3 times and 1% Supervit K was applied once.The field experiment was carried out in 2005-2007 with cv. Galaxy F1 white cabbage onsilty clay soil containing 0.91-1.02% organic carbon and soil acidity pHH2O 7.18-8.21 Micronutrie-ntconcentrations were below the lower range of the content reported for cabbagegrown in non-contaminated areas. Ammonium sulphate significantly increased Mn and Feconcentrations in cabbage heads and decreased B and Mo content. However, the environmentalfactors considerably modified this tendency. The method of N application affectedMn content in cabbage in 2007 and Mo in 2006 and 2007. Slightly higher manganese andmolybdenum concentrations for placement fertilization were noted. In 2005 and 2006, theplacement fertilization at the rate of 75% N and supplemented foliar sprays increasedMo content in cabbage.
