The cereals, such as triticale, oats and barley, did remarkably well at this demo site, particularly treatments 5 and 7. The inadequate growth of the lupins and peas was likely due to the sowing depth, which was deeper as a result of using a planter. Lupins and peas had previously performed well on this site and would be expected to grow well if sown at a suitable (shallow) depth.
