Abstract

Late seeding of wheat (Triticum aestivum L.), oats (Avena sativa L.) and barley (Hordeum vulgare L.) in the spring resulted in large yield reductions, which involved decreased hectoliter weight, 1,000-kernel weight and grain protein yield, increased disease severity and delayed crop maturity. Seed treatment with Vitaflo increased the yield of Keystone barley by an average of 301 kg/ha for all seeding dates during the 2 yr of the study. The seed treatment also increased yield of Garry oats and Opal wheat and increased emergence of oats and barley seedlings. Seedling emergence of wheat was not affected. At several seeding dates, hectoliter weight, kernel weight and grain protein yield of the three crops were increased by seed treatment. Four to six spray applications of Manzate during the growing season increased the average yields of oats and barley at the last three seedings in 1973 by 390 and 554 kg/ha respectively. Spraying with Manzate also increased hectoliter weight and kernel weight, and reduced lodging for both crops. Early seeding appears to be the best way of minimizing the effects of cereal diseases in the Atlantic Region.
