Purpose/Hypothesis The purpose of an experiment testing the effects of rhizobium on nodulation processes and aphid extermination is to find which specific type or strand of rhizobium, natural or inoculants, will better form nodules, and decrease aphid activity. H(a) suggests that inoculant rhizobium will better form nodules and exterminate aphids

Methods Rhizobium Strain Effects On Nitrogen Fixation and Aphid Extermination Natural rhizobium strains N=10 Oil based inoculant rhizobium strains N= days incubation, sub culturing TY plates, growth in media and nodulation Aphids exposed to nodules Nodules formed in effect of inoculant/ natural strains Percentage of aphids exterminated by inoculant/ natural strains ANOVA, Scheffe post-hoc test: inoculants with natural rhizobium (p<.05)
