  1. Crop production: Grow cover crops in arable fields

    A replicated, randomized, controlled study in 2006–2009 in an irrigated maize field in the Tajo river basin, near Madrid, Spain, found similar crop yields in plots with winter cover crops or bare fallows. Crop yield: Similar maize yields were found in plots with cover crops or fallows (9,800–14,900 vs 8,400–14,400 kg grain/ha, dry weight). Methods: There were four plots (12 x 12 m plots) for each of two treatments (barley or vetch, as winter cover crops) and there were two control plots (bare fallow). Cover crops were sown in October 2006–2009 and maize was sown in April and harvested in October 2007–2009. The maize was irrigated (sprinklers) and fertilized (210 kg N/ha, split into two applications, 120 kg P/ha, and 120 kg K/ha).
