This study used experimental data from West Lafayette, Indiana to examine the economic benefits of applying fungicide to corn. The average improvements in yield, gross revenue, and net return (gross revenue minus fungicide and application cost) were 4 bushels per acre, $19 per acre, and -$9 per...

Increases in water demand due to population growth, industrial development and urbanization necessitate economically efficient use of water resources worldwide. This is particularly true in the dryland zones of the world relying on irrigated agriculture for economic development such as in...
