The irrigation intervals were irrigation after 20, 35 and 50 mm evaporation from class A evaporation pan (respectively F-20, F-35 and F-50). The statistical analysis of data was conducted by SAS software using Duncan test. Due to the non-significant difference for seed performance (SP) trait between FI and PRD-75 treatments, it could be possible to save approximately 13% of water by applying PRD-75. The F20-FI and F20-PRD75 treatments had the best results for SP respectively. F20-PRD75 and F35-FI had the best results for oil performance.
