The Influence of Slope Direction and Angle on the Covering Speed of Centipedegrass (Eremochloa ophiuroides (Munro) Hack.)
In order to easily and rapidly establish low-cost grazing grasslands using centipedegrass (Eremochloa ophiuroides (Munro) Hack.) (CG) on abandoned cultivated land, the influences of slope direction and angle on the covering speed of CG were investigated. We established 61 quadrats at varying slope directions and angles, and the planting of CG was performed in 2003. The covering speed of CG was investigated from 2003 to 2008, and the years of point of inflection (YPI) was calculated. The most rapid YPI was 1.0-1.5 years in the quadrats in the S5° W direction with 0 degree slopes, while the slowest YPI was 3.0-3.5 years in the quadrats in the northern direction with 10-20 degree slopes. Therefore, grassland renovation using low quantities of CG seeds, which are sold at a high price in Japan, is favorable on in the southern direction and with a lower slope.
