| Abstract | ||
| A field experiment was conducted during the spring of 2021 at the University of Fallujah. Three irrigation coefficients were adopted: The ratio of Irrigation Water to evaporation from the Cumulative Pan Evaporation has a value of 0.75, 1.0, and 1.25. The results showed that the irrigation interval had variable values and decreased with the increase in the experimental basin coefficient's value and with the growing season's progression. The treatment 1.25 achieved an advantage in results. It was found that the water requirement of peanut plants during the season was 519.74 mm on average when adopting the irrigation water to evaporation from the cumulative evaporation ratio as a treatments in irrigation scheduling. The results showed significant differences between irrigation treatments and the vegetative growth characteristics of peanut plants, such as the average plant height, the number of branches per plant, and the yield. The effect of irrigation treatments on the yield and its components of the peanut plants showed that the 1.25 treatment was superior to the yield, which amounted to 3.2 tons ha-1. The results showed a clear trend in the relationship between irrigation treatments and water unit productivity. The treatment 1.25 was significantly superior to the 1.0 and 0.75 treatments in water unit productivity, which amounted to 7.04 kg m-3, while the lowest value for water unit productivity was 4.78 kg m-3. For the transaction, 0.75. | ||
