  What is WaterManagement ? The integrated process of intake, conveyance, regulation, measurement, distribution, application and use of Irrigation water and drainage of excess water with proper amount and at right time for the purpose of increasing crop production and water economy in conjunction with improved agricultural practices.

  Importance of waterfor plants. Water forms over 90% of the plant body by green or fresh weight basis. Plants require water for: 1. Uptake of Nutrients 2. Maintain their structure through turgidity 3. For the process of Photosynthesis 4. Water is a constituent of protoplasm 5. Water is essential for the germination 6. For the conversion of starch to sugar 7. Water helps in the transpiration 8. Regulates the temperature of plants

  Major Components ofWater Management There are two major components of Water Management: IRRIGATION DRAINAGE • Irrigation : It is the artificial application of water to the soil essential for plant growth. • Drainage : It is the removal of excess water from the field.

  Why to ManageIrrigation water  Different water regime (Level) of Crops.  Uncertainty of Rainfall.  Intensive Cropping to meet the food requirements.  Cultivation of high yielding varieties require more water. Non-Uniform Distribution of Water round the year Shortage of Water Excess of Water Drought Floods

  1. Water Conservation: water conservation involves using water efficiently to reduce waste and maintain quality, ensuring long- term availability for human use and the environment 2. Efficient Irrigation Techniques • Drip irrigation: Delivers water directly to plant roots, minimizing evaporation. • Sprinkler systems: More efficient than traditional flood irrigation. • Scheduling irrigation based on weather and soil moisture sensors.

  3. Rainwater Harvesting •Collecting and storing rainwater from rooftops or surfaces for later use. • Useful in both urban and rural settings. • Helps recharge groundwater and reduce demand on municipal water systems. 4. Watershed Management • Protecting and restoring natural watersheds. • Controlling soil erosion, planting trees, and managing land use. • Prevents sedimentation and maintains water quality in rivers and lakes. 5. Wastewater Treatment and Reuse • Treating sewage and industrial wastewater for reuse in agriculture, industry, or landscaping. • Greywater reuse for toilet flushing or garden irrigation.
