The Effect of Wastewater Applications on Oil Content and Compositions of Canola (Brassica Napus L.)

Abstract

This study was carried out in order to determine the effects of wastewater applications on oil content and compositions of canola (Brassica napus L.) as a pot experiment in greenhouse conditions at Suleyman Demirel University Agricultural Research and Application Center. In The study wastewater applications having different humidity levels (control: 20 kPa, Q1: 20 kPa, Q2: 35 kPa, Q3: 50 kPa, Q4: 65 kPa, and Q5: 80 kPa) were applied to summer canola (Brassica napus L. cv. Licolly) cultivar. The oil content of seed was determined by Soxhlet extraction method and fatty acid composition was determined by GC-MS. In the study, waste water applications at different kPa levels significantly influenced the canola seed oil rate and the oil proportion of the seeds ranged from 35.1% to 42.4% depending on the application. Fatty acid composition of different waste water treatments also had a significant effect on the oil forming palmitic acid, stearic acid, oleic acid and linoleic acid, linolenic acid and eicosanoic acid in canola oil ranged from 6.21% to 4.21%; from 4.15% to 2.27%; from 73.98% to 63.90%; from 17.88% to 14.59%; from 1.93% to 0.93% and from 5.12% to 3.41%, respectively. © 2016, Centenary University.
