  1. Root Phenotyping for Field Management of crops- dryland crops V. Maruthi Principal Scientist (Agronomy) Central Research Institute for Dryland Agriculture Hyderabad

  2. Plant Phenotyping- Agronomic Perspective Crop Management Genotype X E X M Gene based approach : eg., QTLs Breeding strategies New Climate Resilient Cultivars

  3. Plant Phenotyping • Above ground plant phenotyping • Below ground plant phenotyping (Root Phenotyping) Root Morphology: Root Architecture: Spatial and Temporal configuration of Root system Root Topology

  4. Root Phenotyping- Agronomic Perspective Factors • Genotype • Plant population • Tillage • Soil depth • Drought & Excess • Abiotic stress management Measure • Special operations • Fertilisers Drought management measures

  5. Root Phenotyping Drought management measure: Conservation furrow Recommended Practice : One conservation furrow for every three rows of crop plants Field Expt- Greengram- ML267 vs WGG37

  6. Stage 1 (42 DAS) ML267 –No CF ML267 – CF

  7. Stage 2 (63 DAS) WGG37 –No CF WGG37 – CF

  8. Figure . Rooting depth (cm) and root length (cm) at respective soil depths of adjacent and middle rows of mungbean of Conservation Furrow treatment (2011)

  9. Root Phenotyping- Agronomic Perspective Drought management measure: Conservation furrow Recommended Practice : One conservation furrow for every three rows of crop plants Refined practice: One CF for every two rows of crop plants (Greengram – 30 X 15cm)
