| Summary: | <p>In actively growing plants all life processes take place in the
presence of water. For every gram of dry matter produced several
hundred grams of water pass through the plant and are lost into the
atmosphere from plant surfaces by transpiration. Because of this
loss of water, a large amount of water is necessary in order to
obtain satisfactory yields and good quality produce. In central
and southern Saskatchewan the average annual precipitation is
relatively low and ranges from 25 to 38 centimeters (10 to 15 inches).
Therefore, moisture can be the most important limiting factor for
crop production in the area.</p>
<p>The Department of Horticulture Science at the University of
Saskatchewan, Saskatoon has already conducted some fertility and
irrigation trials on a number of vegetable crops. K. E. Hwang in
1970 conducted experiments in this department to study the amount
of water used at different stages of growth by two crops, namely
cabbage and potatoes. These experiments were designed to study
the amount of water used at different stages of growth by snap beans
under growth chamber conditions, and under the infiuence of two
fertility levels.</p>
