Several types of seed treatments were tested to delay the emergence of barley, primarily to improve the growth of legumes undersown at the same time. The period from sowing to 50% emergence was up to 394% as long for treated seeds as for untreated seeds (a delay of 24 days), but total emergence was reduced as much as 42%. CCC and paraffin wax were more promising treatments than abscisic acid, gamma−radiation, or polyurethane varnish. Paraffin did not delay emergence as long as did CCC, especially at low temperatures, but CCC had a more detrimental effect on total emergence.
