Interpretive Summary:

Technical Abstract: Previous research illustrates the benefits of including legumes in rotation with non-leguminous crops. Nitrogen (N) supplied by a summer legume cash crop could contribute to N requirements for succeeding crops. This study examined the N contribution of peanut (Arachis hypogaea L.) residues to a rye (Secale cereale L.) cover crop and subsequent cotton (Gossypium hirsitum L.) crop in a conservation system on a Dothan sandy loam (Fine-loamy, kaolinitic, thermic Plinthic Kandiudults). A split plot treatment structure was used in a randomized complete block design, with main plots as peanut residue retained or removed from the soil surface, and subplots as N application rates (0, 34, 67, and 101 kg ha-1). Rye biomass and N uptake, seed cotton yields, and cotton N uptake were not affected by peanut residue. Seed cotton yields and N uptake were affected by commercial N rates. These results indicate that peanut residue does not contribute N to succeeding crops, however, retaining residue on the soil surface is recommended for Coastal Plain soils.
