An Analysis of Hedging Strategies for Arizona Cotton ProducersThis study compared selected hedging strategies for Arizona upland cotton producers including a no- hedge, a planting hedge, and several technical hedging strategies for the time period 1974-82. Technical hedging strategies relied upon forecasting methods to signal the placing and lifting of hedges. Forecasting methods employed included moving averages, exponential smoothing and linear regression analysis. Hedging strategies were plotted in regions of preference relative to no-hedge and planting hedge strategies.

Estimating Cotton Yields Using Small-Format Aerial PhotographyIn 1981, the University of Arizona's Department of Plant Pathology and Office of Arid Lands Studies (Arizona Remote Sensing Center) began a joint research project to map and estimate concomitant reductions in yield caused by Phymatotrichum root rot (PRR) using simulated orbital and airborne imagery. With support from the U.S. Department of Agriculture, Cooperative States Research Service and NASA-Ames Research Center, substantial progress has been made in improving estimates of yield. While work to date has been limited to cotton, future studies will include additional crops and other diseases.
