A Note on Rhizobium Inoculation of Beans (Phaseolus vulgaris) using the Fluid Drill Technique

Abstract
The conventional method of inoculating Phaseolus vulgaris with Rhizobium phaseoli, using a peat carrier and dry seeds, was compared with a method using a slurry inoculation of germinating seeds, which were subsequently sown with a fluid drill. The mean number of nodules per plant 28 days after sowing was 0·64 (uninoculated control), 2·14 (dry seed), and 7·0 (fluid drill), differences between treatments being significant at P=0·01. Two varieties included in the experiment gave similar responses, and it is concluded that the fluid drill technique has a useful potential as a method of ensuring good inoculation of legume seedlings.
