Ohio Vegetable Production Guide Bulletin 672-01 Irrigation, Mulches, and Frost Control Commercial vegetable and potato growers are showing an increased interest in irrigation. Optimum yields are necessary if growers are to stay in business. Research and practical experience has shown that lack of water at critical stages of crop development is a very important factor affecting yields. With today's marketing situation, more emphasis is being placed on product quality.
Water is an essential component for vegetable growth and health.
To produce almost any crop in Ohio, large quantities of water are needed from either rain or irrigation, or a combination of both. For some crops, 400-600 pounds of water will be needed to produce one pound of dry matter. There are numerous considerations for growers thinking of investing in an irrigation system. Proper soil tilth, organic matter and weed control are necessary for vegetables to benefit from irrigation. Good drainage is very important for successful irrigation.
