Abstract
There exists a tremendous potential for the production of highvalue
cash crops in Saskatchewan with the development of several large
irrigation projects in the province. In such a semi-arid region moisture
is undoubtedly the most important limiting factor in reaching the
maximum production potential. In order to compete in today's competitive
market, it is imperative that production costs are kept at a
minimum, and that economic use is made of water and irrigation systems.
Snap beans (Phaseolus vulgaris L.) are well suited for crop
production under irrigation. Favorable yield responses to irrigation
and yield losses under high moisture stress conditions have commonly
been reported. The existence of critical moisture-sensitive growth
periods have also been demonstrated in snap beans. This sensitivity
is not restricted to moisture stress, but to moisture excess as well.
The optimum moisture level during any growth stage in snap beans,
however, is not well defined. If any growth phases during the ontogeny
of the snap bean are resistant to moderate stress for short periods of
time, or if certain phases prefer a moisture level of less than field
capacity, it could result in savings due to increased yields, as well
as reduced water requirement.
The aim of this study at the University of Saskatchewan,
Saskatoon, was to quantify the effects of a moderate moisture stress
for relatively short periods of time and during consecutive phases of
growth on the yield and development of snap beans.
