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.
متن کاملModel Predictive Control for Real-Time Irrigation Scheduling
Irrigation underpins agricultural productivity. The purpose of irrigation is to match water supply to crop water demand. The effectiveness of irrigation depends on the quality of the timing and duration of watering events, also called irrigation scheduling. Most farmers use heuristic rules to determine irrigation events. This often leads to over-watering which results in lower crop yields and w...
متن کاملImproving 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...
متن کاملCrop 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...
متن کاملDevelopment and testing of an irrigation scheduling model
An irrigation scheduling model (ISM) consisting of a database management system (DBMS), model base and graphical user interface (GUI) was developed for performing irrigation scheduling under various management options for both single and multiple ®elds. The ISM is based on a daily water balance approach and uses climatological, crop and soil data as input. Depending on the availability of clima...
