Influence of Sulphur and Varieties on Oil Quality and Fatty Acid Composition of Linseed (linum Usitatissimum L.)

A field experiment was conducted during 2007-08 at Student Instructional Farm, Narendra Deva University of Agriculture &Technology, Kumarganj, Faizabad (U.P.), India to study the influence of different levels of sulphur and varieties of oil quality and fatty acid composition of linseed. Results revealed that significantly highest oil content (36.65%) was obtained in variety Type-397 as compared to rest of the varieties of linseed. The similar results were also recorded on oil quality parameters viz., iodine value (192.77), saponification value (196.84) and acid value (0.66) with linseed variety Type-397. The fatty acids profile was analyzed by gas liquid chromatography and highest content of linoleic acid was noticed in Type-397 variety, however, it was least in Shekhar variety of linseed. Maximum linolenic acid content was obtained in linseed variety Shekhar (45.23%) followed by Parvati and Type-397. Linseed variety Type-397 was found to the superior in respect of biochemical composition of fatty acid followed by Parvati and Shekhar. Significantly highest oil content and fatty acid composition of linseed with the application of highest tested dose of sulphur a.c.60 kg S/ha as compared to rest of the doses of sulphur.
