Water usage at different growth stages of cabbage and potato plants
Abstract
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.
