Reed canarygrass (Phalaris arundinacea L.) is a desirable pasture
grass on wet areas in the Northern United States and Southern Canada,
but it is a serious and troublesome ditchbank weed in the Pacific Northwest
and Rocky Mountain States. The...

Field plots of cv. Russet Burbank potatoes from a
single seedlot were established at four sites over two
seasons (1985-86) in two locations in Oregon to determine
the role of water-borne inoculum of Erwinia carotovora in
plant infection. One site...

Several methods of infering plant water stress for
irrigation scheduling are based upon measurements of the
environment in which the plants grow. These measurements
include parameters such as soil water content, air
temperature, pan evaporation...

Recent climate change forecasts have aroused growing interest in the influence of water
scarcity and climate on agricultural production and irrigation practice. However, it is common in
the economic literature to aggregate disparate crops when...

Five boron rates and seven water levels were applied
to bush green beans (Phaseolus vulqaris cv Oregon 91G) and
to cauliflower (Brassica olereacea var. botrytis, cultivar
"Snowball Y") in 1989 and 1990 to evaluate their effects on
total yield of...

Field experiments were conducted in 1981 and 1982 to
develop a method for using remotely measured leaf canopy-air
temperature differences (stress-degree-days (SDD)) to
schedule irrigations and to evaluate the effects of
differential irrigation on...

Deliberately underirrigating a crop may yield economic
benefits. The optimal use of water by an irrigator
should be achieved under a deficit irrigation regime. It
is important to know how water deficits affect yields and
the interaction of the...

Response of agricultural crops to irrigation water deficit is well-understood at the
field scale. Broader scale (watershed and county levels) studies have been less frequently
performed. Data collection at the field level for extensive areas is...

Drip irrigation is the slow, even application of low-pressure water to soil and plants using plastic tubing placed near the plants’ root zone. It is an
alternative to sprinkler or furrow methods of irrigating crops. Drip irrigation can be used for...
