How much water needed for wheat?

Wheat needs around 500 to 750 mm (20 to 30 inches) of water per growing season, depending on the variety and climate. The water requirement is highest during the vegetative growth stage (from planting to stem elongation) and the grain-filling stage (from flowering to maturity). During these stages, wheat needs around 250 to 350 mm (10 to 14 inches) of water each. Water stress during these stages can reduce grain yield and quality.

In areas with limited rainfall, wheat can be grown using supplemental irrigation. Irrigation can help to ensure that wheat receives the water it needs to reach its full yield potential. However, it is important to avoid over-irrigating, as this can lead to waterlogging and disease problems.

In order to use water efficiently, it is important to schedule irrigation based on the soil moisture content and the crop water requirements. Soil moisture sensors can be used to monitor the soil moisture content and help farmers to decide when to irrigate. Crop water use can be estimated using weather data and crop growth models.

By following these tips, farmers can help to ensure that wheat receives the water it needs to produce high yields of quality grain.
