Our field trials were carried out in 2005 in Hajdúböszörmény, at two sites. We studied the effect of sulphur (Cosavet DF), copper (Kelcare Cu) and two foliar nutrients with high active agents. Treatments were replicated four times. We took root samples at 4 week intervals, starting in August. The quality of root (sucrose, potassium, sodium and alfa-amino N content) was determined from filtrated beet broth, by an automatic beet laboratory system, called VENEMA. We found that the crop and the sugar yield were significantly influenced by the foliar treatmentsapplication/pdfsugar beetqualityfoliar fertilizationfolyóiratcikkOpen Accesshttps://doi.org/10.34101/actaagrar/23/3214Acta Agraria Debreceniensis23Acta agrar.
