No-till (NT) has been shown to reduce fuel, labor, and machinery costs compared to conventional-till (CT) but very few rice producers in Arkansas practice NT. The low adoption rate is most likely due to difficulties in management but also limited information on the profitability and risk of NT....

This study evaluates both the profitability and risk efficiency of grazing stocker steers on conservation tillage winter wheat pasture using simulation and stochastic efficiency with respect to a function (SERF). Average daily gains are simulated for steers grazed on conventional tillage (CT),...

Farmers around the world rely on IPM practices in order to increase their yields and reduce their losses due to pests. Assessing the impacts of previous IPM CRSP studies is crucial for successful continuance of the program and to provide meaningful recommendations to farmers. This thesis...
