Cotton Irrigation by "Sharbat" Method
When cotton is irrigated using the "sharbat" method, moisture is retained longer, and the cotton does not dry out as quickly. Local manure provides nutrients for the cotton and acts as mulch, reducing water evaporation and improving water infiltration into the soil. For irrigation by the sharbat method, ditches are filled with water 5-6 days before irrigation takes place.
In the sharbat method of irrigation, it is essential to prevent the runoff of manure with wastewater from the field.
Factors that increase irrigation efficiency:
Irrigating cotton through ditches helps save 15% of seasonal water consumption compared to the traditional method.
