چکیده مقاله:

To evaluate the effect of irrigation (irrigation disruption at beginning of flowering, end of flowering, grain filling and control) and biological phosphorus (0, 50, 100 and 150 g/ha) on the seed (obtained from treated plants) germination and seedling growth of Brassica napus L. cv. Hyola 401 , a split plot experiment was carried out based on randomized complete block design with four replications at the Research Farm of Shahid Beheshti Agriculture College (latitude 38° 51' N and longitude 41° 44' E and 1313 m above sea level) in 2010. The quality of harvested seeds under experimental treatments was tested based on ISTA standards. Results of ANOVA showed the significant irrigation disruption and biological phosphorus effect as apart on root length, shoot length and weighted value of seedling vigor and interaction effect between irrigation disruption and biological phosphorus on the longitudinal value of seedling vigor. The highest longitudinal index of seedling vigor (840.24) was obtained from irrigation disruption at the beginning of lowering with 100 g/ha phosphorus, and the lowest longitudinal index (500.09) belonged to plants with no phosphorus application at control treatment of irrigation.
