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)...

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...

'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...
During 2 seasons effects of high and low irrigation (water applied
at -0.6 and -2.5 bars soil water potential, respectively) and
density were evaluated on yield parameters and flower/pod development
at mainstem nodes 2 and 6 (terminal) of 'Oregon 1604', a determinate
snap bean. High and low plant densities were...
