Abstract
Water is the most important limiting factor in agriculture, and its optimal use is so important. The aim of this study was to investigate the effect of different irrigation methods on yield and yield components of wheat (Baharan cultivar) and evaluate water use efficiency. The following treatments included three methods of sprinkler, strip drip and flood irrigation. The experiment was conducted in a randomized complete block design with three replications in the cropping year 2020-2021 in the research farm of University Jihad Organization of Kermanshah province. The research results demonstrated that type of irrigation method had a significant effect on the 1000-seed weight, number of seeds per spike, grain yield, biomass yield, and water use efficiency. Based on the results, the volume of water used in the sprinkler and strip drip irrigation methods was reduced by 22.12 and 46.40%, respectively, compared to the flood irrigation method. Grain yield was 9458.6 kg/ha in strip drip irrigation, 7877.3 kg/ha in the sprinkler irrigation and 4750 kg/ha in the flood irrigation method. In other words, the use of strip drip irrigation method compared to sprinkler irrigation method increased 20.07% and compared to flood irrigation method increased grain yield by 99.13%. According to obtained results, the highest and lowest water use efficiency with values of 2.13 and 0.58 kg/m3 were observed in strip drip and flood irrigation treatments, respectively. Therefore, based on the results and considering the lack of water and the importance of producing more agricultural products, it is suggested to use modern irrigation methods instead of traditional cultivation methods in wheat varieties, especially Baharan variety in Kermanshah province.
