The aim of the present study was to determine dry matter yield, alpha-tocopherol, beta-carotene and some mineral contents in four varieties of fodder pea at different plant growth stages. The highest alpha-tocopherol contents were obtained in the fodder pea variety 'Ates' (29.7 mg kg and variety 'Tore' (29.0 mg kg(-1)) at pre-bud stage, while the minimum alpha-tocopherol contents were found in the varieties 'K' (23.7 mg kg and 'Kr' (23.6 mg kg) of fodder pea at full bloom stage. The lowest beta-carotene (29.7-29.9 mg kg contents were determined in variety 'Kr' at 1/2 bloom and full bloom stages. The highest dry matter yield (9.60 t ha(-1)), potassium ratio (1.67%) and magnesium ratio (0.43%) were determined for varieties at full bloom stage. Maximum potassium ratio (1.64%) and magnesium ratio (0.42%) were observed for pea variety 'K" compared to other varieties, whereas the highest dry matter yield (10.10 t ha(-1)) was obtained for fodder pea variety 'Ates'. In comparison with the fodder pea varieties 'Ates', 'K' and 'Kr'; calcium content (1.67%) of variety 'Tore' was increased at full bloom stage. Lower phosphorus content (0.27%) was found for all fodder pea varieties at pre-bud stage. The dry matter yield, alpha-tocopherol, beta-carotene, potassium, calcium and magnesium contents of variety 'Tore' and variety 'Ates' were found to be higher than other varieties.
