The purpose of this study was to compare forage production yield on Coastal Bermudagrass (Coastal) (Cynodon dactylon) using three sampling techniques [Jenquip's Rising Plate Meter (RPM), USDA Grazing Stick (GS), and forage clippings (FC)] as the control. In addition, a secondary objective was to determine a relationship between the tested measurement tools to forage yield, and comparison of nutritive value related to forage growth and maturity. The research pasture of Coastal was equally divided into 16 plots in a complete randomized design. Plots were randomly assigned to the two treatment types [fertilized (F) and non-fertilized (NF)]. Once treatments were assigned to their designated plots, the pasture was shredded to 2.54 cm of stubble for re-growth. The Coastal was allowed a 17d regrowth period before data was collected, due to previous weather conditions limiting access into the research pasture. Three collection dates were designated and data was collected on d 17, 24, and 31. Following wet weight collections, forage samples were dried to obtain dry matter percentage (DM) and nutritive value determination at Texas A&M AgriLife in Stephenville, Texas. The results on forage yield indicated that GS was the better forage predictor than RPM when measuring Coastal pasture and it is still essential to apply fertilizer to Coastal pasture to improve quality of forage. A significant interaction of d*fertilizer was found (P ≤ 0.05) on IVOMD. Fertilized pasture at 17d was found to yield the highest IVOMD of 0.7195 (P ≤ 0.05). It was confirmed applications of fertilizer increased CP significantly (P ≤ 0.05) compared to unfertilized pasture. As well as, day effected CP levels significantly (P ≤ 0.05) as Coastal maturity increased and CP decreased.
