Scheduling of Irrigation for Summer Peanuts1

On Optimal Irrigation Scheduling

In this paper optimal irrigation scheduling based on a dynamical model is analyzed, and global optimality is proved with the use of sufficient conditions. Krotov’s method of global bounds and Hamilton-Jacobi-Bellman formalism have been used.

Modelling Evapotranspiration of Container Crops for Irrigation Scheduling

Remote sensing of vineyard FPAR, with implications for irrigation scheduling

Normalized difference vegetation index (NDVI) data, acquired at two-meter resolution by an airborne ADAR System 5500, were compared with fraction of photosynthetically active radiation (FPAR) absorbed by commercial vineyards in Napa Valley, California. An empirical line correction was used to transform image digital counts to surface reflectance. “Apparent” NDVI (generated from digital counts) ...

Improving Cotton Irrigation Scheduling in Arkansas

Timely irrigation of cotton has been shown to increase yields, but almost every year producers and researchers observe poor plant development even with irrigation under some condition. Adequate moisture must be present when the cotton crop needs it, but saturated soil conditions deprive the roots of necessary oxygen. Current recommendations lack detail concerning irrigation management. Use of t...

Crop Irrigation Scheduling via Simulation-Based Experimentation

Intraseasonal water allocation to a single crop has been studied extensively. Previous studies have emphasized the need to coordinate irrigation scheduling with several factors including economic and physical constraints, amount of soil moisture available at the time of irrigations, growth stage of the plant, interactive effects from previous and/or subsequent irrigation, and the effect, timing...
