Sažetak
Alfalfa leaves and stems contain different protein and fiber concentration in different stages of growth. The objective of the study was to determinate a dynamic of nutrient accumulation in leaves and stems. The experiment was conducted in two consecutive years (1999, 2000) on three cultivars (Slavonka, Vuka, and Os-88). Chemical analyses of leaves and stems were obtained from first and second growth. Samples were taken at four growth stages per growth (first growth-plant height: 30, 43, 55, 65 cm and second growth-plant height: 30, 39, 45, 58 cm). The results of the study indicate highly statistical influence of growth stage (plant height), cut and investigated year on protein concentration and highly statistical influence of growth stage (plant height) on fiber concentration in alfalfa leaves. Protein and fiber content in stems were highly statistical influenced by year of investigation, cut and growth stage (plant height). Protein concentration in stems decreased by the plant height increasing but a greater decrease occurred in a first growth. Opposite to proteins the fiber content in stems increased by the plant height increasing but a greater increase occurred in a second growth. Cultivars didn’t significantly influenced on investigated traits.
