Nine grass and forage legumes were sown on the reclaimed soil areas with three levels of salinity to determine the effects of saline conditions on the establishment, growth and yield of pasture plants. Monthly salt concentration of cultivated. soil layers of the experimental plots was also studied in the 1979-80 season. 1. The seasonal pattern of salt concentration of cultivated soil layers was closely related to the distribution of precipitation throughout the year. Although the salt concentration began to increase in spring and dropped after rainy season, it was again increased in autumn due to continuous favourable weather. 2. Cover degrees of pasture plants were much decreased according to the increasing levels of salt concentration, but those of tall fescue, tall wheatgrass, alkaligrass and alfalfa were usually more than 48% in the medium saline plot. 3. Tall fescue and alfalfa gave an appreciable dry matter yield, such as more than 600㎏/l0a in the low saline plot, however, the other pasture plants including orchardgrass and ladino clover showed an unfavourable yield. 4. Even though dry matter yields of all pasture plants in the medium and high saline plots were remarkably low compared with those of the low saline plot, tall fescue, tall wheatgrass and alfalfa appeared to be better adapted to salinity than the other pasture plants. 5. On the basis of the results obtained, it is suggested that the relative salt tolerance of tall fescue, tall wheatgrass and alfalfa should be considered in formulating seed mixtures for pasture establishment on the reclaimed salty areas in Korea.
