Effect
Increased produce quality
Kelpak 66 treated Winter barley, cv. Clipper, grown in a growth chamber had on average a 9.8 % higher individual grain dry mass, a 38 % higher grain dry mass/ear, a 52.4 % higher grain dry mass/plant, had 15.3 % less straw dry mass/plant, 16.1 % more total shoot dry mass per plant, 28.3 % more ears, 6.8 % less spikelets/ear, 26.2 % more grains/ear, a 34.5 % higher percentage of fertile spikelets/ear, grains had a 0.5 % lower moisture content and a 12.4 % lower N content as compared to the untreated control. (seed dip was less efficient)
