Abstract
Soil samples were taken from stands of wild European hazelnuts (Corylus avellana) and Turkish tree hazels (Corylus colurna L.), and leaf samples were taken from the same plants.
Corylus avellana cultivars were sampled in a collection located near Zajecar.
From the leaf samples, total water content, osmotic pressure and total soluble solids content were determined.
The soil fertility and leaf macroelement (N,P,K) data were analyzed to evaluate the cropping potential of Corylus species in eastern Serbia.
Soil fertility varied, particularly among the wild European and Turkish tree hazel stands.
The K2O content of the soil in the Zajecar collection averaged 46.5 mg/100 g, and averaged 26.9 in the wild European and 30.3 mg/100g in the Turkish tree hazel stands.
The P2O5 content in the three locations averaged 3.4, 9.2 and 16.5 mg/100 g, respectively.
The organic matter content in the same samples was 5.9, 4.1, and 6.3%, while pH was 5.5, 6.4 and 6.5, respectively.
Since the leaf is most reliable indicator of fruit nutrition, its nutrient content is of great importance.
The average N content (expressed as % dry matter) was 1.66, 1.86 and 2.08%, the average P content was 0.19, 0.25 and 0.20%, and the average K content was 0.42, 0.74 and 0.70%, respectively.
Total leaf water content averaged 56.8, 60.0 and 65.0% and dry matter content averaged 43.2, 40.0 and 35.0%, respectively.
Leaf osmotic pressure averaged 278.6, 301.8 and 311. 4 bars, respectively.
Total soluble solids averaged 8.1, 6.6 and 7.1%, respectively.
