A comparison was made between double rows 15 cm apart
on 76 cm centers and single rows 76 cm apart of 'Oregon
91G' bush green beans at the same planting densities in
three experiments in 1986 and 1987. There was a significant
increase in yields of pods from double rows...
The effects of plant population densities on the growth and development
of six cultivars of bush snap beans (Phaseolus vulgaris L.)
were studied in two field experiments. A systematic planting design
was used to achieve a range of densities from 21- to 110 plants per
m² and a rectangularity of...
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)...

'Tendercrop' and 'OSU 949' green snap beans were grown at
populations varying from 77,000 to 392,000 plants per acre with two
row spacings and six square arrangements ranging from 4 x 4 to 9 x 9
inches. Maximum yield of 10.1 tons per acre (32 percent sieve size
4 and...
The objectives of these experiments were to determine
the feasibility of saving seed from snap bean fields in the
Willamette Valley that have been bypassed for canning and
freezing, and to study the effects of different seed production
methods on yield and quality of snap bean (Phaseolus
vulgaris L.).

Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic pathogen capable of causing white mold, a severe disease in common bean. White mold is of particular concern to the Oregon snap bean processing industry, where processors allow less than
3% incidence in harvested shipments. Breeding for white mold resistance in beans...
