Abstract

'Gaines' and 'Nugaines' varieties of soft
white winter wheat (Triticum aestivum)
yield straw ranging up to about 7 tons per
acre (2). Growing row crops such as dry edible
beans (Phaseolus vulgaris) or sugarbeets (Beta
vulgaris) following such heavy straw production
poses special management problems. Straw
layers that result from plowing down a large
amount of straw may result in reduced bean
yields (supposedly because of nitrogen immobilization),
abnormal sugarbeet root growth,
and tillage and water movement problems.
Much of the tremendous acreage of the irrigated
wheat grown in the Pacific Northwest
is in rotation with sugarbeets, potatoes, beans
and other crops. Therefore, straw residue
management is a major problem with great
economic implications.
