Abstract
The objectives of this research were to investigate effect of types of fertilizer application on yields,
chemical compositions and returned income of planting Whip grass (Hemarthria compressa). Treatments were:
no fertilizer application, applications of six ton/Rai/year of cattle manure, 60 kg of nitrogen ( N) urea/Rai/year
or, four ton of cattle manure plus 40 kg of N urea. It was found that an application of four ton of cattle manure
plus 40 kg of N urea resulted in maximum fresh weight yields (2967 kg/Rai/cutting) and dry matter yield (563
kg/Rai/cutting) with significantly different (P < 0.05) from others treatment. An average of dry matter, organic
matter, crude protein, ash, cell wall, lignocellulose and lignin contents of grass was 22.7, 92.4, 8.9, 4.4, 77.1,
