Crop yield depends upon the amount of available water in the soil and the best use of water can be obtained if fertilizer applications, crop varieties and other management practices are optimum for the water available. Because of evaporation and plant transpiration, a large amount of irrigation water is necessary for improving the agriculture production in some areas. Due to both low relative humidity and low annual precipitation in most parts of the Prairie provinces, water can be the most serious limiting factor for production. The Department of Horticulture Science at the University of Saskatchewan is interested in research on water usage by horticultural crops. Although the response of some horticultural crops to different amounts of soil water has been studied, this experiment was designed specifically to study the amount of water usage, which included both transpiration and retained water within the plant tissues due to plant growth, at different growth stages by two horticultural crops, namely, cabbage and potatoes.
