Conservation Tillage of Grain Sorghum and Soybeans:A Stochastic Dominance Analysis

Three tillage systems: conventional tillage, ridge tillage and notillage are evaluated using stochastic dominance with respect to a function analysis. Each tillage system is evaluated for three cropping patterns: continuous grain sorghum, continuous soybeans, and soybeans after grain sorghum. Conventional tillage continuous grain sorghum would be preferred by risk averse managers, although small changes in production costs and yield differences could lead to indifference between a no-tillage system and the conventional tillage system
