Abstract

Investigations on factors affecting yield of sugar beets during the past two years at Newton and Garland, Utah, have shown two outstanding facts about irrigating sugar beets. First, the amount of water applied may not be as important as the time at which they receive it. Second, sugar beets should not be made to suffer for water in the early part of their growing season.

These observations suggest the need for further studies on method, time and quantity of irrigation. Further information on the most economical use of irrigation water for sugar beets would be of great value to the sugar beet industry.

The object of this study was to determine the best time and type of irrigation, and quantity of water as they influence the yield of sugar beets. In order to reach this objective six moisture variables were used. They consisted of applying water by furrow and sprinkle methods; early and late irrigation in the spring; discontinuing irrigation for the last part of the growing season and continuous irrigation until harvesting; and, frequency of irrigation throughout the growing season. In order to determine the effect of moisture on the yield of sugar beets at different fertility levels, six different fertility levels were combined with each moisture variable.
