Abstract/Contents: | "Texas is a large state with diverse soils, rainfall, and growing seasons. Rainfall ranges from 200 to 1400 mm and the frost free growing season from 185 to 320 days. There are 15 distinct land resources areas in Texas. Lack of a consistent dry period for seed maturation and harvest is the main factor for limited grass and legume herbage seed production in Texas. The small amount of herbage seed production in Texas is primarily introduced and native warm-season perennial grasses grown in South and West Texas where annual rainfall is low and irrigation is available. The Natural Resources Conservation Service, a federal agency, collects, evaluates, and increases seed of native plants at 27 plant material centers. Three are located in Texas. Registered and certified planting material of Tifton 85 bermudagrass and turf grasses are also produced in Texas. Texas is a large and diverse state. It is 1288 km from the northern tip to the southern tip and 1244 km from the eastern edge to the western edge. Soils range from poorly drained clay soils in southeast Texas where rice (Oryza sativa) is grown to deep sandy soils in East Texas. The southern tip of Texas has a tropical climate and is in the USDA Plant Hardiness zone 9b (average minimum temperature of -1.2 to -3.80 C) with an average growing season of 320 days. In contrast the northwest tip of Texas is in the USDA Plant Hardiness Zone 6a (average minimum temperature of -20.6 to -23.30 C) with an average growing season of 185 days. Average annual rainfall ranges from 1400 mm on the eastern edge and decreases moving west to 200 mm on the western edge. Rainfall generally peaks in spring and is low in mid to late summer. However rainfall is very erratic from year to year. Any part of Texas can be in a drought or have a flood any month of the year. Forage producers in South Texas describe the rainfall pattern as prolonged drought interrupted by periodic floods. Many cool- and warm-season agriculture crops and forages are grown in Texas due to the wide combination of soils, rainfall, and temperature." |
