This project was conducted over two years to enhance food security and increase productivity through various irrigation methods, including drip, sprinkler, and Furrow irrigation, along with two cultivation techniques: transplanting and direct seeding. It focused on forage corn planted on June 15 and July 15 at the Chahartakhte research station, located in a semi-arid, cold climate. Each experiment was arranged as a split-plot within a randomized complete block design with three replications. Transplants were planted simultaneously with seed crops. At the end of each crop cycle, traits such as irrigation water use and both wet and dry forage yields were measured. Results showed no significant differences in forage yields among the three irrigation systems. The average water productivity for drip irrigation was 2.76 kg/m³, higher than that of the surface and sprinkler systems. The highest water productivity, 3.15 kg/m³, was observed with drip irrigation and seedling cultivation on the first planting date. On the second planting date, 1070 m³/ha less water was used compared to the first. Water productivity on the first planting date was 8.6% higher than on the second, and seedling cultivation was 9.4% more water productivity than seed cultivation. To optimize water use and increase water productivity, adopting a drip irrigation system, planting on July 15, and using seedling cultivation are effective strategies for reducing water consumption and producing forage corn in semi-arid, cold regions.d cultivation.
