Controlled drainage was compared with recycled subirrigation drainage in clay, loam and fine sand soils. In recycling, a reservoir was used to store drainage waters discharging from the fields. Subirrigation was conducted both through a single and a dual level pipe system. Above-ground biomass, crop N content and crop yield were observed. Subirrigation and controlled drainage effectively raised the groundwater table in the loam and fine sand fields.
