Yield and Morphological Studies With Oats for Forage and Grain Production

Five oat cultivars (Avena sativa L.) were seeded at 38, 67, and 95 kg/ha in 1969, and six cultivars in 1970 and 1972. There were differences between cultivars in grain yield in each year, but in only 1 yr in forage yield. Seeding rates did not affect grain yields in any year or forage yields on the average of the 3 yr; nor did they affect the leanness or ratio of seed to the vegetative parts of the plant. Stem size and plant height decreased with increasing seeding rate.
