English Abstract

The study was conducted at Grdarasha Research Field / College of Agriculture / University of Salahaddin / Erbil during the winter growing season (2014-2015), to investigate the effect of different sowing dates and seeding rates on the yield and quality of Rapeseed genotypes.

The highest seed yield ,harvest index and oil %(4494.55 kg.ha-1 , 31.77% and 39.55%) were recorded from the interaction treatments (Pactol* 15th Oct.*4 kg.ha-1 ,Raja*31st Oct.* 4 kg.ha-1 and Pactol*15th Nov.*6 kg.ha-1) respectively .While the highest values (68.80,21.16,9.34 and 15.09 %) of fatty acids (oleic, linoleic, linolenic and erucic acids) were obtained from interaction treatments (Raja*31st Oct.* 4 kg.ha-1,Rendy*15th Oct*6 kg.ha-1, Pactol*15thOct.*6kg.ha-1and Raja*15th Oct.*4 kg.ha-1)respectively .The highest seed yield(3769.11 kg.ha-1) was recorded from Pactol genotype ,while the lowest value (1584 kg.ha-1) was recorded from Rendy genotype.

On the other hand the highest seed yield was recorded from sowing rate of 4kg.ha-1 and sowing date 15th October.
