This textbook focuses on the scientific and practical aspects of water management under changing climatic conditions. It covers:Basics of irrigation - importance, history, sources of water (rainfall, reservoirs, tanks, groundwater), and key terminologies like field capacity, wilting point, and irrigation efficiency.Soil-water relations - how soil texture, structure, and porosity influence water retention, movement, and availability to crops.Measurement and dynamics - methods to measure soil moisture, infiltration, permeability, evapotranspiration, and factors affecting them.Irrigation scheduli...
This textbook focuses on the scientific and practical aspects of water management under changing climatic conditions. It covers:Basics of irrigation - importance, history, sources of water (rainfall, reservoirs, tanks, groundwater), and key terminologies like field capacity, wilting point, and irrigation efficiency.Soil-water relations - how soil texture, structure, and porosity influence water retention, movement, and availability to crops.Measurement and dynamics - methods to measure soil moisture, infiltration, permeability, evapotranspiration, and factors affecting them.Irrigation scheduling and techniques - criteria for when and how to irrigate using methods such as check basin, furrow, ring basin, and border strip systems.Drainage and efficiency - types of surface and subsurface drainage systems, their design, advantages, and suitability for different soils.Water use efficiency (WUE) - how climatic, genetic, and management factors affect crop water productivity, and strategies to enhance irrigation efficiency at the farm and project level.OverallIt promotes climate-smart, sustainable, and efficient irrigation practices to ensure food security and water conservation.
