Phosphorus accounts for one of the largest energy inputs in canola production. Understanding the effects of phosphorus on yield and oil quality of canola will help in increasing its chances to better fit in the present cropping systems of Pakistan. This study determined the response of canola hybrids to different sources of phosphatic fertilizers. Two canola hybrids, namely Hyola-43 and Hyola-401 were grown using four different sources of phosphorus (MAP, DAP, NP, SSP) during 2004-05 and 2005-06. Canola hybrids differed significantly for all the yield and oil quality traits during both years of study. Hyola-43 resulted in 6.7 and 13.4% increase in seed yield over Hyola-401 during 2004-05 and 2005-06, respectively. Hyola-43 also produced significantly higher values of oil and protein content over Hyola-401. Increase in oil and protein content varied from 3.3-5.5% and 5.0-5.1% in 2004-05 and 2005-06, respectively. Differences in seed yield, yiel d parameters and oil quality were non-significant in response to phosphatic fertilizers.
