Residual effects of winter cover crop species on summer hay [abstract]. Agronomy Abstracts. 2004 CDROM. Interpretive Summary: Technical Abstract: A 12-month system consisting of winter and summer forages is needed in the South to manage manure nutrient in the swine effluent spray field. The interactions and competition between summer and winter forages and their management is the focus of this research. Earlier results showed hay and yields of N, P, K, Mg, Mn, Ca, Fe, Zn, and Cu in winter cover crop of red clover (Trifolium pretense L.), berseem clover (T. alexandrinum L.) or annual ryegrass (Lolium multiflorum Lam.)with different harvesting days. The current research on bermudagrass yields reports the effects of winter management and species on summer yield of hay and nine elements. The bermudagrass hay yield and K, Mg, P, Mn, and Zn were significantly greatest for the former berseem clover plots. On annual yield basis including both summer and winter forages, the best harvest date for the winter cover crop was the one which minimized the late spring competition effects of winter crop on the bermudagrass but this was not the best harvest date identified in earlier research for the winter crop alone. |
