- Abstract
This research was conducted as a field study to determine effects on yield and yield parameters of sunflower plants and plant water stres index of deficit irrigation with drip irrigation applications of Siirt climate conditions. Irrigation issues in research; 1 full irrigation (I100 control subject) and full irrigation 80% (I20), 60% (I40), 40% (I60) and 20% (I80) rate cuts made four irrigation and is formed from no irrigation water is not applied I0. It made a statistically significant relationship between the yield and yield parameters were determined as a result of statistical analysis. Effect on yield and yield components of irrigation was significant at the 1% level and has been affected at different levels. Depending on the applied water shortages and climatic conditions, evapotranspiration of sunflower plants, plant water stres index, chlorophyll and yield is greatly affected. CWSI highest value during the vegetation period 0.39, I0 the lowest value in the CWSI for irrigation is set at 0.19 in fully irrigated I100. In the study of sunflower grain yield began to decline, the CWSI threshold value determined from the previous infraret thermometer observations from irrigation has been identified as 0.29. According to the study's results made it is not recommended to do or make cuts in Siirt deficit irrigation on sunflower must have if it is the vegetative stage (before flowering) is made up of 20% is recommended.
