Sažetak
The objectives were to examine efficiency of Zn biofortification and in vitro bioavailability of wheat grain under different levels of N fertilization and foliar Zn application. Foliar Zn was applied as ZnSO4 (0 and 1.5 kg/ha Zn) and N fertilization was carried out with four levels (0, 110, 145 and 180 kg/ha) growing two winter wheat cultivars (Srpanjka and Renata) under field conditions. Among all examined sources of variation in this trial (cultivar, N, foliar Zn and their interactions), foliar Zn application had highest effect on whole grain Zn concentration (23.3-32.7 mg/kg ; F=106.03 ; p<0.01) and Zn concentration after in vitro digestion (4.1-5.4 mg/kg ; F=45.86 ; p<0.01) while percentage of bioavailability was under highest effect of cultivar (F=42.63 ; P<0.01). Results indicating that biofortification is an effective approach to increase a whole grain Zn concentration as well as Zn bioavailability.
