| Summary: | <p>Irrigation is potentially one of the most important
tools of the agricultural producer in increasing crop production
in many parts of the world. In an area like Saskatchewan,
the production of crops important to the horticulturist
can be expected to attain significant economic importance
only with the use of supplementary water. The forthcoming
opening of tens of thousands of acres of irrigable
land in the South Saskatchewan and other dam projects will,
in all probability, bring about an expansion in the largescale
production of the high-cash crops on the Canadian
prairies. While the mechanics of irrigating field crops
formulate a well-developed science, much is still to be
learned about the improvement of irrigation efficiency via
a thorough understanding of how much water the plant needs
for maximal yields of the desired plant part and when it
needs that water. It has been with the goal of accurate
timing of water applications via clarification of previously
reported results on moisture-sensitive periods in
the plant-life cycle that the research described herein
was carried out at the University of Saskatchewan, Saskatoon.</p>
