Effects of inoculation with rhizobium and nitrogen fertilizer on snap beans, soybeans and lima beans

Ma, Mei-hwa Wang 15 November 1977 (has links)
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
