Does it pay to irrigate vegetable crops in Iowa?

What does it cost to irrigate? and under what conditions are these costs, plus a profit, returned to the vegetable grower?

No complete answer to these questions can be given, because of the widely varying conditions involved—differences of rainfall, of crops, of costs, of soil, of topography. But considerable light is thrown on them by experiments which the Vegetable Crops Subsection of the Iowa Agricultural Experiment Station has conducted during several years at Ames and on “Muscatine Island.’’
