Abstract
Tow important characteristics of arid and semi arid regions are wind and wind erosion which accelerate desertification process. Farmlands are on of the major sources of soil particles detachment and consequent erosion. Windbreak is an effective tool in reducing wind speed and making microclimates in its windward and leeward. Hussein Abad Sarbisheh plain is located in and arid climate and Sistan 120-days wind has destructive influence on soil and yield of agricultural fields. In this research, live windbreaks (Zea Mays and Sorghum bicolor) were created in different arrangements and densities at three replications. Wind speed was monitored in definite distances from windward and leeward of windbreak. Data of wind speed monitoring was analyzed by SAS statistical software and the results revealed that triangular arrangement in three densities (i.e., density of 60 cm in rows) is the most effective arrangement in density of windbreak to reduce wind speed. Since the windbreak was designed in opposite direction of prevailing wind, then its arrangement and density showed no influence on wind direction.
