| This figure shows the difference in soil
water use between spring wheat and safflower.
This comparison is made between a field planted
to continuous spring wheat and a field planted in
a spring wheat-safflower rotation. Thus, the 1995
crop was wheat on both fields. In autumn 1994,
the safflower field was drier than the wheat
field, reflecting greater water use by safflower.
Last year, water use was similar in the two
fields (both planted to wheat) and the soil water
content difference from autumn 1994 still existed
in spring 1996. Spring wheat uses water earlier
in the growing season than does safflower, so
that the wheat field was actually drier than the
safflower field in late June and early July.
After mid-July, safflower consumes more water
than does wheat and the safflower field was drier
than the wheat field for the remainder of the
season. The difference in soil water content at
the end of the season (1.6") was similar to
the difference at the start of the season
(1.5"). This indicates wheat and safflower
used similar amounts of water this year. |
