Excerpt from Cotton Irrigation in the Southwest The acreage of irrigated cotton in the United States has increased rapidly during recent years, and it is now irrigated in many areas where it was unthought of 30 years ago. In 1953 the United States irri gated a total of acres of cotton. Texas alone irrigated about acres of cotton in 1948, acres in 1953, and acres in 1955. Cotton is adapted to a wide range of soil conditions and produces well on both fine and coarse-textured soils. It is relatively tolerant to saline soil conditions that com mouly occur on irrigated lands in the Southwest. Cotton is generally considered a warm climate crop and needs at least 190 rather warm, frost-free days to produce a high yield. However, good production has been attained under a variety of conditions rang ing in elevation from below sea level in the Imperial Valley of California to feet in Arizona, and in climate from the arid regions of the Southwest to the subhumid areas of the Southeast.

The urban water demand in Southwest Texas has grown rapidly in recent years due to the population increases in urban areas, which caused conflict between municipal and agricultural water use. Deficit irrigation is one important measure for solving this problem. A field experiment with seven different irrigation treatments and four cotton varieties was conducted at the Texas AgriLife Research and Extension Center at Uvalde in the summers of 2008 and 2009 to examine the water saving potential and related phenological/physiological responses in Southwest Texas. The results showed that: 1) The threshold deficit ratio for a traditional deficit irrigation scheme falls between 0.7 and 0.8 for cotton production in Southwest Texas under a low energy precision application (LEPA) sprinkler irrigation system. The 70% evapotranspiration (ET)-initialled regulated deficit irrigation scheme (70R) performed well in maintaining lint yield in most cotton varieties tested. The significant changes detected in lint quality failed to introduce premiums or discounts in cotton price. 2) The phenological parameters (plant height, node number and flower/fruit number) showed clear trends that illustrate the relationship between increased stress level and decreased plant growth and development. The observed inconsistency of the physiological responses in the two growing seasons may imply that physiological parameters are not good direct predictors of lint yield if measurements are conducted only on a point basis. The partitioning coefficients of boll dry weight in both years failed to show a significant difference between deficit irrigation treatments and the control, indicating that reallocation of carbohydrates may not be the major factor of maintaining lint yield for the deficit irrigation treatments. 3) Economic analysis showed that due to the low water price, it is not currently profitable to adopt deficit irrigation. In case that water price is increased, it may become more profitable to adopt deficit irrigation. This work provides reference information to water authorities and policy makers to set quotas for municipal and agricultural water use and to value water properly through setting different water prices.

The W. C. Austin Project, in the cotton and cash-grain farming area of southwestern Oklahoma, represents on of the first attempts to introduce irrigation of a project type into a subhumid area. Before irrigation, cotton farms averaged about 240 acres and cash-grain farms about 320 acres. This multiple-purpose project was constructed to provide irrigation water, flood control, and a municipal water supply for the city of Altus. Water was delivered to a few acres in 1946, and to the entire project in 1950. Development of the project occurred in a period of favorable farm incomes. Farmers met costs of development largely from income or reserves, without going into debt.
