To evaluate the impact of Indigo seed treatment on cereal and chickpea yield and grain quality.

 Indigo 76 microbial seed treatment was applied @ 3mL/1000kg seed one day prior to planting. There was no significant impact on establishment, NDVI (~crop biomass) or grain yield across the four crop types evaluated. There was however a significant reduction in grain screenings in Indigo treated plots with a reduction in average screenings from 5.6% to 4.9%.The level of impact did not made any difference in the receival grade for any crop. There was no significant difference in barley retention but a clear trend to increased retention when Indigo was applied. Retention increased from 59 to 62%. No change in grain quality was obtained in this situation. In this trial, the application of Indigo 76 microbial seed treatment did not achieve a significant impact on yield or quality grade when applied to wheat, barley, durum or chickpea seed.
