Optimal Timing of One Supplemental Irrigation

Economic analysis of the optimal level of supplemental irrigation for rain-fed figs

ABSTRACT- The aim of this study is economic analysis of supplemental irrigation (SI) for rain-fed fig trees in the south of Iran, with and without micro-catchment water harvesting systems (MCWHS). Under no MCWHS, by decreasing about 55 % of applied water, the fig yield decreased about 28% and net income increased twice compared with the maximum yield condition. In general, the ...

Timing of Supplemental Feeding for Tilapia Production

The staged addition of feed to fertilized fish ponds was evaluated by adding fertilizers to 15 ponds stocked with Nile tilapia Oreochromis niloticus, then adding feed at half ad libitum rates once fish in the ponds reached a target weight. Each pond was stocked with 750 fish (3 fish/mz), and each treatment included three ponds with first feeding at (a) 50 g, (b) 100 g, (c) 150 g, (d) 200 g, and...

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.
