In previous years, at Corvallis, yields of bush snap beans
varied among planting dates. In order to obtain additional information
on the effect of planting dates on the growth, development and
yield of snap beans, four field plantings and two greenhouse plantings
of the variety O.S.U. 2051 were made.

A procedure for model-assisted climate impact assessment is
developed. The approach combines data from observations and
atmospheric general circulation models (GCNs), and provides the basis
for a potentially valuable means of using information derived from
GCMs for climate impact assessments on local scales.
The first component of this procedure is...

The heat unit concept of time-temperature relationships
is used in this thesis as a means of studying the
temperature element of the climate at nine Oregon stations.
The stations, Astoria, Baker, Burns, Eugene, Medford,
Pendleton, Portland, Roseburg, and Salem, were selected on
the basis of distribution and availability of Weather...

A recent surge in the development of irrigated agriculture in
the Fort Rock Basin of the Oregon High Desert has resulted in two
principal types of agricultural operations in the area: cow-calf
operators and cash-crop agriculturalists. The agroclimatic
hazards associated with the present situation and the implications
of those hazards...
Agricultural production in the Sahelian region of Africa is
among the lowest in the world. Cyclical infestations of locusts and
grasshoppers have contributed to this low productivity. The infestations
appear to be triggered by heavy rainfall at the beginning of a crop season
after extended drought. Because locusts and grasshoppers...
Increased temperature and precipitation variability and frequent extreme weather events due to climate change pose a threat to farming operations and agricultural communities. The recent IPCC assessment shows that the projected climate change will, on average, reduce wheat yields by 5% in temperate regions without adaptation and even more if...
