Agriculture production remains a major mainstay of the Texas High Plains economy. However, the primary groundwater source (Ogallala Aquifer) that supports the intensive nature of irrigated agriculture and livestock operations is waning rapidly which raises alarm for future sustainability of agriculture production in the area. The main goal of the study is to analyze the economic feasibility of corn silage and sorghum silage under reduced irrigation in the Texas High Plains. The specific objectives were to: 1) Estimate water response function for irrigated corn silage and sorghum silage. 2) Use the input response function to determine optimum levels of input to maximize profit for corn silage and sorghum silage production. 3) Perform a comparative analysis of water use between corn silage and sorghum silage and estimate potential water savings. 4) Predict the effect of forage quality of corn silage and sorghum silage on milk yield per ton of forage dry matter. Data for sorghum silage were obtained from the Texas AgriLife Research Center in Amarillo, Texas from sorghum silage trials 2007 to 2014 whereas corn silage data were obtained from 2009 to 2013 corn silage trials from the State Silage Corn Performance Test at Etter. Models were developed to determine the effect of water on corn silage and sorghum silage yield. These models were further used to determine the optimal input levels of total available water and applied irrigation water to maximize profit. The R2 value from the restricted model relating corn silage and sorghum silage to total available water received explained 99% and 97% of the variation in yield, respectively. The profit for irrigated sorghum silage $43/ton) and irrigated corn silage $48/ton) in the Northern Texas High Plains are $183/acre and $471/acre, respectively, at a natural gas price of $4/Mcf whereas the Southern Texas High Plains, had $242/acre and $554/acre, respectively, at electricity price of $0.074/kWh. A total of 258,068 acre-feet of water will be needed to produce 4,180,711 tons of corn silage whereas 239,692 acre-feet of water will be required to grow 4,646,340 tons of sorghum silage to meet the feed (silage) requirement of dairy cows in the Texas High Plains. The amount of water saved if corn silage is replaced by 50% irrigated sorghum silage and 50% dryland sorghum silage is 138,222 acre-feet. Crude protein, in-vitro true digestibility, starch, and lignin content of corn silage forage quality explained 99% of the variation in milk yield while sorghum silage forage quality explained 98%. Although there is 16% increase in milk yield in favor of corn silage due to forage quality, it is economically profitable to feed the dairy cows with sorghum silage as far as buying or growing both silages to formulate ration for dairy cows are concerned. The production cost of corn silage in the feed component of dairy cows is 15% more than sorghum silage per year. Improvement in crude protein, in-vitro true digestibility, and starch content of sorghum silage will increase the quantity of milk produced per ton of forage dry matter. Considering global concerns on water scarcity coupled with unpredictable climate changes, it is economically prudent to consider sorghum silage especially in the Texas High Plains where the groundwater (Ogallala Aquifer) is waning.

The Texas High Plains is one of the most prolific crop-producing areas in the United States. Agriculture plays a vital role in the economy of this region. The agricultural industry in this area faces various challenges: environmental, economic, etc. Due to extreme weather conditions and climate change, crop production in the Texas High plains is facing a great threat. Crop production needs irrigation water. The primary source of irrigation water in this region is the Ogallala Aquifer. The saturated thickness of this aquifer is being depleted day by day, which is a big concern for the irrigation of crop production (Guerrero et al., 2019). A survey of the literature shows that few studies have investigated the cropping pattern for a specific crop based on production amount, but there is no study that broadly investigated the cropping pattern based on harvested acres for this region. So, it is important for policy purposes to investigate the spatiotemporal change of cropping patterns in this region. The main objective of this research is to visualize the historical change of cropping patterns in the Texas High Plains from the standpoint of geographical concentration and spatial autocorrelation. Historical county-level agricultural census data were collected from the United States Department of Agriculture’s (USDA) National Agricultural Statistical Services (NASS) from 1978 to 2017. Exploratory data analysis (EDA) techniques were employed to examine the geographical concentration and the spatial dependence of crop production among nearby locations. Results of temporal changes indicate that harvested acres and the number of farms trend down through the study period. Maps were generated for each variable of interest which shows how much cropland acres have changed over time. The Gini coefficient and the quantiles of size distributions were computed for all variables of interest to analyze the change in geographical distribution. Total harvested cropland acres were nearly uniformly distributed across the 39 counties whereas irrigated harvested cropland acres were concentrated in a smaller number of counties, which is an indication of the change in geographical concentration in the Texas High Plains. Both total and irrigated harvested corn, cotton, sorghum grain, and wheat acreages were concentrated in a smaller number of counties over time while wheat production was mostly concentrated in the northern part of the region. The number of acres harvested for a specific crop relative to the number of total cropland acres show that most counties had more than 50 percent of its harvested cropland as cotton indicating that cotton is the prominent crop in the Texas High Plains. The percentage of acres of irrigated harvested cropland relative to total harvested cropland acreage has decreased over time. The Moran’s I test statistics for both irrigated and non-irrigated cropland areas suggest that there was spatial dependence among the neighboring counties in the production of crops in this region. In summary, there was a spatiotemporal change in cropping patterns in the Texas High Plains over the study period.

In the Ogallala Aquifer, the Texas High Plains' primary water source, withdrawals continue to exceed the aquifer's limited recharge. Producers are compensating with water-conserving production techniques such as transitioning to more efficient irrigation technology, implementing conservation tillage practices, reducing the amount of irrigation applied, and alternating the crops they plant. Given the current condition of the semi-arid region, alternative production methods are necessary to enhance farm profitability. One alternative being considered by producers is the production of high-value crops. High-value crops, including vegetables, can increase overall producer profitability. Initial project experiments have demonstrated the potential for viable vegetable production; however, no studies exist to prove the economic viability of these crops in the Texas High Plains. This study analyzes the economic feasibility of producing high-value vegetables so producers may make an informed decision regarding the incorporation of vegetable production into their existing operation. This information will benefit not only producers faced with declining water availability but also small landowners considering more productive uses of their land. Tomatoes, jalapeño peppers, and sweet corn were produced in an open field at the USDA-ARS CPRL/Texas A&M AgriLife Vegetable Production Lab in Bushland, Texas using surface drip irrigation both with and without the use of black plastic mulch. Field production data including water use, labor hours, input costs, and yields were collected through personal communication with research faculty. Additional data were collected from the Texas A&M AgriLife Extension crop budgets, the United States Department of Agriculture's Agriculture Marketing Service, the United States Department of Agriculture's Economic Research Service, and a review of existing vegetable production literature. These data were compiled to create enterprise budgets including revenue, variable costs, fixed costs, and total profit for each vegetable with mulch and without mulch under surface drip irrigation, on a per-acre basis. Economic data for traditionally irrigated corn, cotton, and wheat were obtained from the Texas A&M AgriLife Extension crop budgets. Several economic measures, including return on investment, profit per acre-inch of irrigation water applied, and breakeven prices were analyzed to provide producers with the information needed to make decisions. In addition, sensitivity analyses were conducted to evaluate how changes in crop prices and labor hours would affect producer profit. An online survey was distributed to producers implementing vegetable production within the study region to identify current management practices. Innovative production systems such as high tunnel systems and greenhouses offer several benefits to these producers, specifically protection from the harsh environment. Additionally, survey respondents provided information regarding higher revenue possibilities that exist through other marketing outlets including farmer's markets, local grocery stores, and restaurants. Implementing vegetable production in an existing enterprise is an alternative that can help increase or maintain overall producer profits, especially for producers faced with declining water availability. Despite the high investment and high labor costs, the results indicate vegetable production in the Texas High Plains has great profit potential. It is important to note that conservative estimates of revenue were utilized in this study. In addition, because specialty crops are not eligible for Agricultural Risk Loss Coverage, Price Loss Coverage, or Marketing Assistance Loan programs, producers should consider the risk associated with field production and methods to reduce the risk. Further research should be conducted to evaluate the economic feasibility of vegetable production in high tunnel systems and the use of other locally-grown fruits and vegetables to enhance farm profitability.

The dairy industry in the Texas High Plains has undergone rapid expansion in the past two decades, growing from 12,066 head in 2000 to 262,622 head in 2015. This growth is due to establishment of new dairies as well as migration of dairies from other states. Many factors contributed to this growth, including availability of land, lower input prices, and a less stringent regulatory environment. Dairies use water both directly through drinking and facility maintenance and indirectly through irrigation of crops used for feed. It was hypothesized that overall water use and crop composition in the study region changed in response to the increased demand for silage from the dairies. Silage must be produced locally since the high moisture content makes it difficult and expensive to transport. The source of water for irrigation is the Ogallala Aquifer. This has caused concern as the aquifer is being depleted faster than it can recharge. It was also hypothesized that dairies are generating economic value through supporting businesses for production inputs as well as processing facilities that have been established in the region. No existing literature examines the localized economic impact of dairies across specific types of businesses. The specific objectives of this study were to assess the impacts of the expansion of the dairy industry on water usage, crop mix, and business composition (including type, employment, number of establishments, and income). In addition, projections for dairy growth were used to estimate water use changes 10, 20, and 30 years in the future. Data from the beginning of the expansion period in 2000 were compared to the most current data (2015) in order to detect any changes that occurred. Irrigated crop data were collected from the Farm Service Agency (Farm Service Agency, 2018) and data on businesses were collected from the US Census Bureau’s County Business Patterns (County Business Patterns, 2017). In addition, a spatial analysis was conducted to examine how the location of dairies has impacted the study region. Results indicated that the regional crop composition increased in silage acres as did associated water usage across the study period. However, total irrigated acres decreased during this time; therefore, silage production displaced other crops such as feed grains. Several industry sectors showed increases in employment and number of establishments, such as construction, transportation, and animal slaughter. More houses are needed for additional workers employed by dairy processing facilities, milk and dairy products need to be transported to and from processing facilities, and slaughter facilities have expanded from the increase in dairy cull cows. In summary, the overall change in the region due to dairy expansion was an increase in silage acres, which generates higher value for the water pumped when compared to crops grown for grain. However, total irrigated acres in the study region declined, indicating the increase in irrigated acres for feed for dairies was offset by a decrease in irrigated grain acres. In addition, dairies have increased the number, size, and employment of related business establishments locally, which has increased the economic activity in these rural areas. Projections indicate that growth will continue at a slower rate in future years. Thus it can be expected that the dairy industry and other supporting sectors will continue to be a major contributor to rural economies.
