Research Abstract	Growth responses of napiergrass (Pennisetum purpureum Schum.), sorghum (Sorghum bicolor Moench), bahiagrass (Paspalum notatum Flugge) and rhodsegrass (Chloris gayana Kunth) to applications of the organic form of nitrogen (N) were examined under field condition. Nitrogen was applied at the rate of 15 gm-2 in the form of inorganic N (IN) or Organic N (ON). The total dry matter yield in the ON treatment was similar to those in the IN treatment for sorghum, but were higher than in the IN treatment for rhodsegrass.
