| Predicted crop yields and wind erosion rates from a multi-year/multi-crop growth simulation model provided input into a multi-period recursive QP model to evaluate erosion implications during the transition to dryland crop production on the Texas Southern High Plains. Three farm-program participation options were considered in this study. Participation in an extension of the current farm program resulted in an increase in net returns and wind erosion rates above nonparticipation. Imposition of a soil loss limit without consideration of a flexible base option can significantly reduce discounted present values. Increasing risk aversion across producers affects crop mix selection which can result in lower per acre wind erosion rates for this particular... |

| This study estimates some of the economic impacts of a program that would allow farmers to save a part of their annual surface irrigation water allocation. The objective would be to save water in full allocation years to be used in water short years. The study area consisted of the El Paso County Water Improvement District. Results indicate that optimal temporal water use would increase district net farm revenue by three percent or less above actual water use. For the study area vegetables were the most profitable crop while laser leveling was not economically feasible. |

| This study evaluated implications of increased bollworm problems in a 20-county area of the Texas High Plains relative to cotton yields and economic impact. Results did not indicate a serious effect of bollworms upon lint yield when insecticides were used for control. However, estimated annual reduction in farmer profit due to the bollworm for 1979-81 was over $30 million. Yields were estimated to decline about 300,000 bales without insecticide use and about 30,000 bales with insecticide use. This decline suggests potentially serious implications for the comparative economic position of cotton in this region if insecticide resistance were to develop among insect pests. |

| Cost, returns, and economies of scale for small, medium and large catfish farms with recirculating ponds are presented for the upper Texas coast. Internal rates of return are 0.150, 0.183 and 0.219, respectively. Total investment is higher than farms with static ponds but investment per unit production capacity is 7 percent to 16 percent lower. Average total cost per pound is between $0.565 and $0.541, (11 percent 20 percent lower than farms using current technology). These results have implications for regional comparative advantage of catfish production as well as incentive for adoption of new technology in conventional ponds. |

| A dry year irrigation suspension has been proposed as a way of reallocating water when aquifer levels are low for the Texas Edwards Aquifer. Under this program, farmers would be paid to suspend irrigation to allow more spring flow or nonagricultural pumping. When irrigation is suspended in the east, springflow response is markedly larger than when suspended in the western portions of the aquifer. Most acreage participates when a $90 per acre payment is offered before the cropping season. Considerably higher payments are needed and less water saved for a suspension program instituted during the cropping season. |

| Control of salinity offers an opportunity to increase agricultural production along the Red River of Texas and Oklahoma. However, absolute benefits and the distribution of those benefits are sensitive to the crop yield effect of SAR (sodium absorption ratio). The effect of SAR on crop yield is not well defined. This study estimates agricultural benefits of a chloride control project as $65 million, not considering any SAR effect and $117 million with an SAR effect. Further, distribution of benefits was reversed between the eastern and western portions of the study area. |
