Datafile: Grassland legacy effects on yield of a follow-on crop in rotation strongly influenced by legume proportion and moderately by drought

Abstract

Dataset contains the dry matter and nitrogen yield responses of a Lolium multiflorum crop (summed across harvests). The L. multiflorum crop was sown on plots comprising grassland communities of one to six species (and one to three functional groups) that were growing for the previous two years. An experimental summer drought was implemented on half of each plot during the grassland phase but not the crop phase. Data were collected in Wexford, Republic of Ireland (52.299584, -6.506458) in 2020.
