Abstract
The closed horizontal drainage 200 ha in area of Fergana Research Station was not repaired for 52 years in the past. A major repair of the drainage in the past 5 to 7 years resulted in maintaining of water table at critical level and slowing down of soil salinity to slightly saline level. It helped to sustain soil fertility and obtain higher yields of agricultural crops in the area.
