The applied Zn rates were 0, 2.5 and 5 mg/kg Zn. Due to Zn doses the yield incrased significantly. Zn fertilization increased the plant Zn content and decreased the plant P and Mn content significantly. For N, K and Mg there was no significant effect.application/pdfzincfertilizationgreenhouseinfo:eu-repo/semantics/article
