Utilization of Smart Irrigation for Different Irrigation Systems on the Growth and Production of Different Rice Cultivars

Abstract

A field experiment was conducted at one of the research stations of the College of Agricultural Engineering Sciences / University of Baghdad for the summer agricultural season of 2021, to evdluate the utilization of smart irrigation systems with dry planting and its impact on the growth and production of three local rice cultivar treatment. for irrigation systems in cluded: subsurface and surface drip irrigation, sprinkler irrigation, and flood irrigation, and three local cultivar treatment of rice Anber 33, Jasmine and Furat were studied. The characters studied were irrigation system capacity, irrigation system efficiency, plant height, and rice yield. The experiment was carried out using a nested design, according to a randomized complete block design RCBD with three replications .The results were statistically analyzed and the least significant difference LSD was used at the level of 0.05 to compare the averages of the treatments. The results indicate that the surface drip irrigation system outperformed in obtaining the highest dripping discharge stood 3.03 l. h-1. subsurface irrigation system obtained the highest irrigation efficiency stood 93.0%. The flood irrigation system obtained the highest plant height stood 80.66 cm and the highest yield reached stood 3.424 tons ha-1. The Anber 33 cultivar achieved the highest irrigation flow in the flood irrigation that reached stood 114.4 l. h-1, the highest irrigation efficiency achieved by Furat cultivar which was stood 82.2%, and the Anbar 33 cultivar treatment achieved the highest plant height of 91.67 cm and the highest yield stood 3.873 tons ha-1. Jasmine cultivar treatment the highest discharge in the sprinkler irrigation capacity was stood 23.28 l. h-1, the highest discharge in the hydraulic dripper was stood 3.04 l. h-1. The two-way interaction between the flood irrigation system and Anber 33 cultivar treatment achieved the highest plant height stood 110.7 cm and the highest yield stood 4.043 tons. ha-1.. The sub-surface drip irrigation system in the Anbar 33 cultivar treatment achieved the highest irrigation efficiency of 93.6%. the surface drip irrigation system in the Anbar 33 cultivar treatment achieved the highest discharge of drippers which reached 3.05 l . h-1. Subsurface drip irrigation in Jasmine cultivar treatment achieved the highest dripping discharge stood 3.05 l. h -1.
