Supplemental irrigation based on measuring soil water content can improve wheat growth and yield. By testing different irrigation levels, researchers found that maintaining soil water content at 75% during the jointing stage and 70% at anthesis led to higher photosynthetic rates, better dry matter accumulation, and increased water use efficiency. This irrigation pattern resulted in the highest grain yield and irrigation production efficiency. Overall, the study suggests that this specific irrigation strategy can optimize wheat production while conserving water resources.
