Abstract:
The current study was conducted at Sari county prior 2015 and 2016 seasons with split plot design with three main factors (irrigation interval) and three sub main factors (irrigation water amount) in a complete block design in three replications. 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.
