Module 1
Irrigation: Definition-necessity of irrigation – environmental effects of irrigation – sources of water – planning concepts of irrigation schemes- irrigation systems- lift and flow irrigation – modes of irrigation – layout of irrigation schemes – historical development and irrigation in India through ages. Soil-water-plant relation – classes and availability of soil water- water requirement for crop – optimum moisture for crop growth – depth of water and frequency of irrigation – crop seasons and important crops in India. Crop period and base period – duty, delta and their relationship – factors affecting duty – commanded areas and intensity of irrigation. Consumptive use of water – evapotranspiration – determination of consumptive use – irrigation efficiencies.
