Última The effect of cover crop and crop rotation on soil water storage and on sorghum yield PAB Azevedo,Demóstenes Marcos Pedrosa de; Landivar,Juan; Vieira,Robson Macedo; Moseley,Daryl. Crop rotation and cover crop can be important means for enhancing crop yield in rainfed areas such as the lower Coastal Bend Region of Texas, USA. A trial was conducted in 1995 as part of a long-term cropping experiment (7 years) to investigate the effect of oat (Avena sativa L.) cover and rotation on soil water storage and yield of sorghum (Sorghum bicolor L.). The trial design was a RCB in a split-plot arrangement with four replicates. Rotation sequences were the main plots and oat cover crop the subplots. Cover crop reduced sorghum grain yield. This effect was attributed to a reduced concentration of available soil N and less soil water storage under this treatment. By delaying cover termination, the residue with a high C/N acted as an N sink through... Tipo: Info:eu-repo/semantics/article Palavras-chave: Rotation sequence; Soybean; Cotton.
