| Abstract | ||
| The experiment was conducted in Agricultural college / Tikrit university , during winter season 2010 using four levels of organic manures ( sheep manure ) which were ( 3 , 6 , and 9 ton / dunum ) and four harvest dates which were ( 114 , 128 , 142 and 156 days after planting ) . The experiment was applied using a Randomized Complete Block Design in three replication . The results showed that the fertilizer in a level ( 6 ton / dunum ) increased significantly plant height , vegetative growth weight , and bulb length . The fertilizer levels were not significant differences among them in other studied characters . The first harvest date increased dry matter percentage of bulbs , whereas the second harvest date increased vegetative growth and double bulb percentage . The forth harvest date increased other studied characters . According to the interaction , the fertilizer level ( 6 ton / dunum ) at the forth harvest date increased in most studied characters . | ||
