This trial (Daly & Chamberlain, 2002) was conducted in Canterbury, New Zealand on the organic Harts Creek Farm. The peas were sown at 290 kg/ha and had a basal application of 250 kg/ha of reactive phosphate rock applied to correct a low soil phosphate concentration. The trial had four replicates and EM was applied at the previously described rate twice during crop growth. EM increased pea yields by 31% over the control.
Effect of soil and foliar application of effective microorganisms on yield of pea
This trial (Javaid, 2006) from 2006 in Lahore, Pakistan titled Foliar application of effective microorganisms on pea as an alternative fertiliser, looks at the effect of effective microorganism application on various yield parameters. In the trial the number of pods per plant, pod length, number of seeds per pod and grain yield per plant was significantly increased when EM was applied, while the effect of soil amendments on these parameters was not significant (Tab. IV). See the table below for more detail.
