Abstract EN
A field experiment was conducted to evaluate the effect of planting dates (2 Feb.
and 27 Feb.
/2017) and application of nitrogen and phosphorus fertilization (0 N: 0 P, 60 kg/ha N: 30 kg/ha P and 90 Kg/ha N: 60 kg/ha P to oil percent and unsaturated fatty acid analysis composition of two rapeseed cultivars (Sherally and Dunkild), This factorial experiment was conducted in a Randomized Complete Block Design with three replications.
The results demonstrate that late planting date significantly decrease Linolenic acid and Oleic acid.
Oil percent and unsaturated fatty acids were significantly responded due to application of nitrogen and phosphorus fertilizer, the treatment 60 N: 30 P produced maximum value for each fatty acids α-Linolenic acid, Linolenic acid and Oleic acid.
High content of Linolenic acid and Oleic acid were recorded in Sherally cultivar.
The variation amount of oilpercent and unsaturated fatty acid were noticed due to the interaction treatment of planting dates and fertilizers, the maximum amount of unsaturated fatty acids was produced in each interaction between first and second planting date with 60 N: 30 P fertilizer, and the same result were obtained due to the interaction between each cultivars with the 60 N: 30 P fertilizer.
Oil percent and α-Linolenic acid produced maximum amount in the interaction between second planting date 27 Feb.
and Dunkild cultivar, while the highest amount of Linolenic acid and Oleic acid were noticed in the interaction between first planting date 7 Feb.
and Sherally cultivar.
The interaction treatment of planting dates, nitrogen and phosphorus fertilizer and cultivars gave significant variation in the amount of oil percent and unsaturated fatty acids composition analysis.
