A doctoral thesis at University of Basrah examines the effect on the growth, yield and quality of rapeseed crop.

A doctoral thesis in College of Agriculture at Basrah University examined the effect of nitrogen levels and spraying with gibberellin and ethephon on the growth, yield and quality of rapeseed crop.

The study presented by researcher Sondos Kamel Jabbar concluded that a nitrogen fertilizer addition led to improve the vegetative growth  characteristics and this was reflected positively at the yield components and then the seed yield, protein yield and oil yield. For the two seasons of the study, increasing nitrogen fertilizer led to an increase in the percentage of saturated palmitic fatty acid for the two seasons and stearic and unsaturated linoleic fatty acid.

The study recommended that adding nitrogen at the level 300 kg h-1 , spraying gibberellin at the level 400 ml l-1 and ethephon (1.5 ml l-1 Ethio 48% Ethephon).
