Separate Furrow Irrigation Boosts Crop Yields, Slashes Water Use in Drought-Prone Region
Separate furrow irrigation for film maize in southern Ningxia hill region was studied. Results showed that compared to full irrigation, separate furrow irrigation had equal output but increased water use efficiency by 12.44% and used half the water. Compared to no irrigation, economic output and water use efficiency increased by 38.24% and 38.65% respectively.
