Optimal Levels of Irrigation Water and Nitrogen Use in Cotton Production
MetadataShow full item record
A dynamic optimization model which introduces an intertemporal nitrate-nitrogen fertilizer and irrigation water optimal decision rules for cotton production in the South High Plains of Texas. The results indicate that optimal nitrogen applications critically depend on initial nitrate-nitrogen levels and nitrogen prices. Also, the results indicate that the optimal levels of irrigations water is used to derive irrigation water ans nitrogen demand functions and a cotton supply function.
