Özet

Field experiments with boron (B) (0, 1, 3, 6, and 9 kg ha(-1) B) were conducted in 2005 and 2006 to determine the optimum economic B rate (OEBR). Critical soil test and tissue B values far grain yield (GY) and total yield (TY) production for 'Krik' cv. and 'Bezostiya' cv. grown on B-deficient calcareous Aridisols in Eastern Turkey were determined. Averaged over the two years, 'Krik' and 'Bezostiya' cvs., the OEBR was 6.4-5.6 kg B ha(-1) an average GY yield of 2.0-3.8 Mg ha(-1), and 5.9-5.6 kg B ha(-1) an average TY yield of 5.5.0-10.8 Mg ha(-1), respectively. The average soil B content at the OEBR was 1.15-0.92 mg kg(-1) while leaf tissue B content amounted to 24.0 and 30.3 mg kg(-1) for 'Krik' and 'Bezostiya' c-vs., respectively. Boron application decreased tissue calcium (Ca), and magnesium (Mg), and increased tissue nitrogen (N), phosphorus (P), potassium (K), zinc (Zn), iron (Fe), copper (Cu) and manganese (Mn).
