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 both crops and on outer quality, head
hollowness and internal...
Yield reductions due to competition of weeds with crop plants
can be extremely important. Early weed competition can be as important
in reducing crop yield as weed competition for the entire
season.
The objectives of this study were (1) to determine the weed
control achieved by narrow row-cropping patterns, (2)...
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 snap bean cultivars, 'Oregon
1604' and 'Galamor'. Effects on soil water potential
(SWP), leaf water potential...

The effects of modifying air temperature, soil temperature,
and soil moisture levels on flowering, fruiting, and chemical composition
of Tendercrop snap beans were studied in experiments in
the field and in the greenhouse during 1961, 1962, and 1963.
High maximum temperatures of 95-105° F. during bloom reduced
the percent set...
