Abstract
Seasonal dry matter production of the turf-typed grazing pasture dominated by Zoysia tenuifolia in Yonaguni Island, Okinawa was investigated. The five experimental plots were arranged with the separation of 50 m from seabluff to inward. The accumulated pasture production increased from 40 g/m2 to 500 g/m2 according to distance from the sea-bluff to inward. Dry matter production of shoot per day was constant at the close area to the sea-bluff, while it increased toward the inland direction. It is estimated that the vegietation of Zoysia tentuifolia pasture was maintained by both salty water and sea breeze, and by appropriate carrying capacity.
