SWIFT CURRENT, Saskatchewan, July 23 (Reuters) - Potential
yields of spring wheat and durum are down across much of the
Canadian Prairies after some of the driest conditions in
decades, scouts noted on the annual CWB Market Research Services
crop tour.
Parts of Alberta and Saskatchewan received less than 40
percent of normal rainfall during May and June, raising concerns
about canola and durum supplies, as Canada is the biggest
exporter of both.
In northeastern Alberta, scouts measured spring wheat yields
of 40.3 bushels per acre on average, down about 20 percent from
a year ago, said CWB weather and crop specialist Bruce Burnett
in a report late Wednesday. Canola, which is harder to estimate
when it is flowering, showed signs of poor germination.
In southern Alberta, durum yields measured about
three-quarters of last year's counts, while yields from Medicine
Hat, Alberta into southwestern Saskatchewan looked 13 percent
less than a year ago.
Rain earlier this week in central Alberta should boost wheat
yields somewhat, and extend canola's yield-determining flowering
period, Burnett said.
There are exceptions to the trend of falling yields.
In western Manitoba and eastern Saskatchewan, a region
soaked with too much rain a year ago, spring wheat yields
averaged 42 bushels per acre, up two bushels from 2014.
Earlier this week, scouts noted spring wheat and canola
yields in central Saskatchewan that were in line with a year
ago, while southern Manitoba spring wheat yields may set a
record high after ample rains.
The tour's three routes converge on Regina, Saskatchewan
late on Thursday. CWB will release Western Canada yield
estimates for spring wheat, durum and canola on Friday.
