| The identification of optimal management zones, including optimal uniform grid size, is a complex issue central to the successful implementation of variable rate input application. A novel economic optimization model is developed and applied that identifies the economically optimal management zone. Variable rate seeding can increase profits and reduce risk. |

| Economic feasibility of Texas Blacklands corn production in relation to sorghum, wheat, and cotton is studied. Biophysical simulation generated yield data are integrated with an economic decision model using quadratic programming. Given the various scenarios analyzed, corn is economically feasible for the Blacklands. A crop mix of half corn and half cotton production is selected under risk neutrality with wheat entering if risk aversion is present. Corn and grain sorghum production are highly substitutable. Profit effects attributed to changing corn planting dates are more pronounced than profit changes resulting from altering corn population or maturity class. |

| This study combines whole farm economic analysis with biophysical simulation techniques in order to achieve a twofold objective. First, the study seeks to develop a multiple enterprise vegetable farm model with a production and marketing decision interface and, second, to determine optimal production practices for Kentucky vegetable growers. Three vegetable crops are examined: tomatoes, bell peppers and sweet corn. The findings indicate that the risk associated with vegetable production can be significantly mitigated with diversification of production mix and with a greater number of transplanting dates. However, this reduction in risk comes at a high cost in terms of expected net returns. |

| This research explores a possible reason for the inconsistent results from previous study on the profitability analysis in precision agriculture - different standards of identifying possible erroneous observations for PA datasets. By comparing the results from the different standards of identifying possible erroneous observations, this research raises concerns about the negative impacts of different standards of identifying possible erroneous observations on the profitability analysis of PA, and provides some suggestions for the standard which could be used in the future profitability analysis of PA. |

| Economic analysis was conducted on hypothetical agronomic research on new crop cultivars for Arkansas dryland soybean and wheat producers. In relation to farmers attitudes toward risk, the microeconomic effects and level of adoption of yield variability reducing cultivars were analyzed utilizing a production management decision-making model formulated with mathematical programming techniques. The study indicated that negative covariance between crops continues to be an effective means of reducing production risk associated with yield variability. However, under varying circumstances, agronomic research on the breeding of new soybean and wheat cultivars with reduced yield variability is worthwhile if there is only slight concurrent reduction in expected... |

| One supplier of broilers without giblets (WOGs) offers customers a choice between paying Urner Barry's WOG quote or a formula price based on futures prices. From a buyer's perspective, the formula price is second-degree stochastic dominant, thus acting a marketing inducement. The formula price allows the seller to set almost perfect cross-hedges of WOGs with corn and soymeal. Stochastic dominance results suggested that the seller's dominant strategy would shift from the unhedged Urner Barry quote to the unhedged formula price as risk aversion increased. The hedged formula price was prominent in optimal portfolios of pricing strategies. |
