Abstract :

Wheat is one of the most important crop in Fars province and because of water shortage there is a great emphasis on its water use efficiency in production field. A field experiment was conducted in 2021 and 2022 in order to evaluate wheat yield and its components in raised planting system in Arsanjan, Fars province. The experiment conducted as split plot with three irrigation treatments (irrigartion equal to evapotranspiration, 80% of evapotranspiration irrigation (moderate drought stress) and 60% of evapotranspiration irrigation (severe drought stress)) as main plot and three planting methods (conventional flat planting, 60 cm raised bed planting and 120 cm raised bed planting) as sub plot. The results indicated that drought stress significantly decreased traits such as plant height, grain yield, ear number, seed number and biological yield, while increased seed protein. Raised bed planting significantly increased the traits in comparison with conventional flat planting. So that plating with 120 cm raised bed increased grain yield by 22.1% and 25.9% in first and second year respectively this increasing was 17% for biological, 75 for ear number, and 21% for seed number. Planting in raised bed system reduced the adverse effect of drought stress on wheat traits. In conclusion based on the observed results planting in raised bed system can be adopted as an appropriate planting pattern for improving yield and water productivity in experimental region and similar climates.
