The possibility of using smart irrigation in the fixed sprinkler irrigation system and its impact on the performance of the system and the growth and production of the maize yield
Keywords:
smart irrigation, operating pressure, sprinkler service area, maize yieldAbstract
A field experiment was conducted to evaluate the effect of the operating pressure of the fixed sprinkler irrigation system on some soil properties and maize production at Al-Raad research station located in the Akkarouf area on the Abu Ghraib-Shala road, 1 km north of the highway (Baghdad - Anbar) for the agricultural season 2021. Three Operating Pressure Levels for fixed irrigation system included: 1, 1.5 and 2 bar. The following characters were studied, which are the amount of water used during the season, sprinkler service area, plant height and maize yield. A randomized complete block design (RCBD) was used with three replications, and the least significant difference under probability (LSD= 0.05) was used to compare the averages of the transactions. The results showed the following: The superiority of the operational pressure of 1 bar in the amount of water used during the season (81 m3. Season-1), superiority of the operating pressure of 2 bar in obtaining the the highest value of the sprinkler service area was 367.71 m2, the highest plant height was 190.11 cm, and the highest yield of the crop was 6.46 tons. ha-1 comparing with other treatments.
