The study was conducted to determine the yield and quality of white flower grass un'der the influence of factors such as planting density, fertilizer and cutting periods. Three experiments were conducted by method of experimental in the field. Experiment 1: studied the effect of three planting densities (20 x 30 cm, 30 x 30 cm and 30 x 40 cm). Experiment 2: studied the effects of three levels of organic fertilizers (10, 20 and 30 tons/ha). Experiment 3 studied the effect of cutting period (40, 50 and 60 days). Results indicate that at different planting densities, white flowers grass was growing and developing well. The highest yield was found at treatment with density of 30 x 40 cm. Experiment with different levels of fertilizer is also a strong influence to the yield and quality of grass. The best treattpent in experiment 2 was 30 tons organic fertilizer/ha. Different cutting period has great influence on regeneration of the grass. The height of the grass mats also increases with cutting period from 40 to 60 days. Dry matter and crude protein of white flower grass are high.
