Özet

Seeds of three chickpea varieties were grown under zinc (Zn) and nitrogen (N) fertilized conditions and levels of zinc, phosphorus, phytic acid and protein concentrations as well as phytase activity were determined. In the field experiment, seed Zn concentrations increased with Zn fertilization in all varieties. Zinc fertilization had a negative effect on seed phosphorus (P) and phytic acid (PA) concentration. Phytic acid to Zn molar ratio decreased with zinc fertilization. Protein content of seeds increased with N and Zn fertilization. Zinc nutrition had no direct effect on phytase activity. Grain Zn, P, PA and protein concentrations varied depending on chickpea variety.
