Description
This experiment was conducted to determine the maximum potential yield of native plant species when maintained in an unlimited water and natural rainfed environments to support the PHYGROW forage production model. Samples of the dominant rangeland plant species found in Central Texas were collected eight times during a 365 day period in 1995-96. Weight per unit basal area, and canopy area increased significantly throughout the growing season in bunchgrasses and sod/rhizomatous grasses, respectively, in water unlimited plots. Individual plant weight of forbs increased with irrigation, although it was only significant for the legume, Texas Bluebonnet. Woody plants exhibited little response to supplemental irrigation. All species exhibited unique patterns of growth depending on plant architecture and successional status.
