The responses of 'Oregon 1604' snap beans (Phaseolus vulgaris
L.), 'Early Thorogreen' lima beans (Phaseolus lunatus L.), and
'Takii's Extra Early' soybeans (Glycine max L.) to two methods of
inoculation with rhizobium (seedcoating and furrow treatments) and
rates of nitrogen fertilizer were studied in field experiments.
Nitrogen rates ranged from 0 to 84 kg/ha.
Nodulation was increased significantly by inoculation but decreased
by nitrogen fertilization in three crops. Yield of snap beans
was increased significantly from increasing nitrogen fertilizer but
was not affected by inoculation. Neither nitrogen fertilizer nor
inoculation influenced soybean yield.
For soybeans and lima beans, furrow inoculation resulted in
significantly higher nodulation than the seedcoating treatment.
Nodulation of snap beans and soybeans was significantly decreased
by nitrogen fertilizer in inoculated plots but not in check plots. Plant
weight of lima beans was significantly increased by nitrogen fertilizer
only when seedcoating inoculation was used.
Plant stands of snap beans were increased 118% by captan seed
treatment but nodulation was significantly reduced. / Graduation date: 1978
