Plastic film mulch and drip irrigation can help maize plants grow better and produce more yield while using water more efficiently. By using these methods, maize plants grew faster, taller, and had more leaves. The treatments also increased the weight of maize grains and overall yield. Limited supplemental irrigation under plastic film mulch was found to be the best method, improving water use efficiency and crop yield significantly compared to other methods. This approach not only saves water but also increases maize production, making it a great choice for farmers looking to conserve water and grow more crops.
