Effect of Seven Annual Legumes on the Yield of Corn and Oats on Norge Loam
1957
Harper, Horace J. | Gray, Fenton
SypnosisOat yields were increased more than corn yields when residue from legumes grown in a 3-year rotation with these crops was returned to a reddish prairie soil in central Oklahoma. However, the average production of corn over a 24-year period was higher than the average production of oats. Although seasonal rainfall in this area is more favorable for oats than for corn, soil temperature is more favorable for rapid decomposition of organic matter when corn is growing rapidly than when oats is making its most rapid growth. Consequently, a higher soil fertility level is needed for the maximum production of oats than for corn under the climatic environment that prevails in this sub-humid region.
