Variation in Fatty Acid Composition of ‘Tulameen’ Red Raspberry Seed Oil by the Application of Nitrogen Fertilizers and Organic Manure

Abstract

In this study, the application of nitrogen fertilizer and organic manure in various rates on the percentage and the composition
of the fatty acids in‘Tulameen’ Red Raspberry (Rubus idaeus L.) seed oil were investigated. A randomized complete block design
with there different rates 0, 56, 112; and 112 split kg N ha-1and two different rates (30 ton ha-1 and 40 ton ha-1) ofsheep manure
was utulized. Linoleic acid (49.25%), alpha linolenic acid (38.33%) and palmitic acid (4.97%) were typically the most abundant
fatty acids; and composition of these fatty acids in seed oil were different in all treatments. However, the changes in percentage
of the fatty acids in Tulamen seeds with these treatments were not significant. The effects of either application time or rate of the
fertilizers tested on fatty acid percentage in Tulameen seeds was not significant.
