Abstract

The experiment was conducted at the Agricultural Research Center in Upper Egypt 2016-2017. We were aiming to see the effect of spraying Si (100 ppm) and Se (50 ppm) 4 times under different planting on productivity and oil quality oil variety Giza 6 under different planting dates. In this research; Si and Se with early sowing (1May) applications produced significant increases Length and branching, Attributes of productivity, oil quality of variety Giza 6.Results show that oil content ranged from 55.48% to 60.10%, The percentage of oil decreases with the delay of planting dates. There is a variation in the refractive index (1.464-1.468) with different dates or Si and Se. The acidity rate increases with the delay of cultivation. The peroxide value decreases with the first reset. And lower iodine number with first replant It contains Oleic (55.49- 60.05%). The oleic is reduced with delay in planting, while linoleic increases with the delay of planting and spraying with silicon and selenium. The highest value of O/L ratio was with early implantation and spraying with silicon and selenium. Unsaturated fatty acids exceed saturated fatty acids with silicon and selenium spray.
