Productivity of five no irrigated leys and natural vegetation at Lithochori of Evritania

The productivity of five leys with five binary mixtures and indigenous vegetation was studied in mountainous area of Central Greece (altitude 1100 m). The binary mixtures were consisted by Lolium perenne and one of the following legumes: Lotus corniculatus, Medicago sativa, Trifolium hybridum, T. pratense and T. repens. Indigenous vegetation was used as control. Neither nitrogen fertilisation nor irrigation was applied. The productivity was 740-1600 and 560-1540 g m-2 dry matter for the first and the second year respectively. The most productive ley was that with T. repens. The botanical composition analysis showed that the contribution of L. perenne was relatively small. The productivity of indigenous vegetation was comparable with that of leys. Its botanical composition proved quite sufficient.
