Abiotic in-crop constraints for wheat

Back

Waterlogging

Constraint - Waterlogging

Symptoms

  • Decreased germination in waterlogged areas
  • Chlorosis of older leaves
  • Reduced growth/stunting of plants
  • Poor root development
  • Plant death if waterlogging is prolonged

Damage

  • Yield can be reduced due to stunted plants or decreased germination
  • In severely waterlogged soils, large areas of crop can be completely lost

Control

The adoption of raised beds and controlled traffic systems, as well as underground and surface drainage systems can be very effective if implemented correctly. Choosing more tolerant crops, planting early, and using long season varieties, as well as increasing seeding rate and controlling weeds can also be effective control methods if the problem is not severe.
