Peanut‐Corn Intercrop Performance as Affected by Within‐Row Corn Spacing at a Constant Row Spacing

Abstract The advantages of intercropping a cereal with a grain legume are often limited by the dominance of the cereal, which severely inhibits the legume. A field experiment was conducted in 1983 and 1984 in southern Maryland to determine the effects of within‐row corn ( Zea mays L.) spacing on a peanut ( Arachis hypogaea L.)‐corn intercrop. ‘Southern States 35A’ corn was planted in rows 1 m apart, with a double row of ‘Florunner’ peanut planted midway between. Peanut spacing was uniform, but within‐row corn spacing varied from 0.125 to 0.335 m in a systematic design with spacing in adjacent pairs of corn rows differing by 0.03 m. Separate sole‐crop plots of either four corn rows with 0.155‐m spacing or…
