While this site had a low population of weeds no yield increases were apparent. Few variety differeces were apparent at this site, though Hoegrass + Glean reduced yield of Crabook significantly.
Few crop effects were experienced at this site. The major effect was due to variable fertility in replicates 3 and 4 and this resulted in the somewhat uyp and down nature for the Glean, Logran and hoegrass results.
This site had a major problem with soil acidity and only triticale and oats grew satisfactorily. Barley was strongly influenced by the acidity and many herbicide results are more variable than could be expected.
Weeds: low burden annual ryegrass, though high in some areas.
