the 2nd week after planting. The 1st harvest was conducted two months after planting, 2nd harvest one month after the 1st and the 3rd harvest one month after the 2nd harvest. Grass was cut closely to the ground surface at harvest time. Eight plants were sampled at each harvest time to calculate above ground dry matter (kg.ha-1). The fresh plants were dried in open air conditions for three days; then, cut and dried at once in a hot-air oven for 24 hours before weighing. Soil samples were collected weekly at two points in each main plot at 0-30 cm and air-dried in order to determine gravimetric soil moisture (%). STATISTIX v8.0, statistical analytical software, was used to analyze variance and compare the treatments’ means
