Abstract: Alkali soils, about 2,500,000 ha. of the Indo-Gangetic alluvial plains are characterized by impermeable surface soils and hydraulically impeded subsurface horizons. A survey of irrigation practices adopted by the farmers of the area revealed that more than 70% of them obtain their irrigation by pumping the good quality ground water and applying an average of about 150 and 60 cm for rice and wheat, respectively, in comparison, with 100 and 45 cm applied at the research farm of the Central Soil Salinity Research Institute (CSSRI), Karnal. This note considers irrigation efficiency improvements.
