Presentation Transcript

  1. Crop water productivity modeling: Demand and impact at a field level Example: On-site Impacts- Water Demand and Water Productivity • Current Vs alternative AWM scenarios

  2. Example: CWR and Consumption of crops grown on Vertisols under current and alternative AWM scenarios

  3. Example 1: WR, Consumption and WP of wheat grown on BBF and Flat seedbeds BBF and Flat beds planted on July 1 and August 15, respectively

  4. Example 2: WR, Consumption and WP of rice, grass-pea and extensively grazed grass grown on flat areas

  5. Impacts • Use of BBF increased water demand, but reduced evaporation loss • BBF increased WP with respect to effective rainfall • Growing rice instead of grass-pea or grazing increased water demand, but reduced evaporation • Use of BBF on drainable and rice on flat land increased Economic Water Productivity
