Özet
Millets are indigenous to many parts of the world and are more widely grown, especially in areas where water is limited. The most widely grown millet type is sorghum (Sorghum bicolor L.). A field study was carried out to determine the effect of deficit irrigation regimes on grain yield and seasonal evapotranspiration of proso millet (Panicum miliaceum L.) in the Thrace Region of Turkey. The field trials were conducted on a loam Entisol soil, on Öğretmenoğlu and Beydarı, the most popular varieties in the research area. In the study, the split plots experimental design with three replications was used. Eight different irrigation issues are considered, including combinations of the vegetative (V), flowering (F) and grain formation (Y) phases of the plant (including dry conditions, NoI). Results showed that proso millet was significantly affected by water stress during the sensitive flowering stage. The highest grain yield was obtained with 4.09 t ha-1 from Öğretmenoğlu and 4.03 t ha-1 from Beydarı, which was rinsed (VFY) in all development periods. Seasonal irrigation water use and evapotranspiration of the irrigated (VFY) in all development periods were 318 and 579 mm, respectively, for the non- stressed treatment. The seasonal water yield function was calculated as Y = 0.4087 ET + 144.03, and the seasonal yield-water response factor value was calculated as 0.57'.
