Oil Yield and Fatty Acid Composition of Spring Sun flower as Affected by Sowing Date, Intra Row Spacing and Nitrogen Dose

This study was carried out to determine the efficiency of nitrogen (N) doses (0, 30, 60, and 90 kg N ha−1) under supplemental potassium (K) application (50 kg K2O ha−1) on black cumin in 2011 and 2012. The results showed that increased N levels resulted in increasing seed yield and N and K contents in seed, while oil content decreased. The seed yield and oil yield were peaked at the doses of 60 kg N ha−1and 50 kg K ha−1. An increase in N doses caused a reduction in oil content regardless of K supply. Saturated fatty acids and oleic acid were slightly increased by K application, while minor changes in linoleic acid were detected. It was concluded that 60 kg N ha−1with supplemental K application should be advised for enhancement in seed yield, oil yield, and N and K contents in seeds of black cumin without significant changes in fatty acid composition.

Carotenoid Profile

The aim of this work was to evaluate the effect of mechanical pressing on jussara oil yield, oxidative stability and carotenoid profile with or without heat application. Firstly, jussara pulp was centrifuged for juice extraction, and the resulting cake was dried until reaching 10% moisture content. Then, oil extraction was performed in an expeller press at 25 ºC (cold pressing) and at 50 ºC (hot pressing). The process performance was evaluated by the oil yield, and the crude jussara oil was characterized for fatty acid composition, acid value, carotenoid profile and oxidative stability. Jussara oil contained 74% unsaturated fatty acids, mainly oleic and linoleic acids (48% and 24%, respectively). The oil yield was almost twice as high for the hot process as compared to the cold one. Additionally, hot pressing resulted in 25% higher total carotenoid content as compared to cold pressing, with β-carotene as the most abundant one. Hot and cold pressing showed no difference in oil oxidative stability and fatty acid composition.

Fatty Acid Compositions

Boron is a member of the metaloid group of elements and is an important essential microelement needed for normal crop growth and development. This research was conducted in 2015 in Hatay (Mediterranean region of Turkey) to determine foliar application of Boron effect on protein ratio, starch ratio and oil yield and oil components of corn. To evaluate the response of foliar application of boron to corn, four boron doses (control, 4, 6 and 8 mg/m2) were applied at the three growing stages (V2; 2 leaves with visible collars, V4; 4 leaves with visible collars,V2V4; half dosage was applied V2 and half dosage was applied V4). The experiment was carried out in a split plot design with three replicates using cultivar 82 May 70. Ears were harvested and randomly selected for analysis of protein ratio, starch ratio, oil yield and fatty acid composition. Even though there was no significant difference in Boron treatments in terms of protein and starch, significant difference was determined in oil yield and fatty acid composition. In general, foliar application of higher Boron doses (6, 8 mg /m2) increased oleic acid, palmitic acid, stearic acid. In the early development period (V2), foliar application of boron caused an increase in the content of linoleic acid and linolenic acid of corn.

Growing Medium

This study was aimed at the examination of the effects of increased salinity of growing medium on the fatty acid composition and yield of rhizome essential oil of Curcuma longa L. The analyses (gas chromatography and gas chromatography/mass spectrometry) of the transesterified petroleum ether extract of rhizomes grown under non-saline conditions (0.0 mM NaCl; control) showed that the dominant fatty acids were oleic (48.6%), myristic (15.0%), linoleic (7.9%), palmitic (6.8%) and linolenic (2.4%). Increased growth medium salinity (25.0, 50.0 and 75.0 mM NaCl) provoked significant changes in the relative amounts of some acids. Increase of NaCl concentration caused an increase in the amount of linoleic and linolenic acids, but had the opposite or no effect on myristic and oleic acids quantity. The yield of the essential oil obtained from fresh control rhizome (non-saline conditions) was 1.7%. When C. longa was grown in a low-salinity medium (25.0 mM NaCl), the oil yield remained the same. However, under high salinity conditions the yield reached 2.9% (50.0 mM NaCl), i.e. 3.1% (75.0 mM NaCl). Our results clearly show that the studied plant species is susceptible to high salinity induced stress.
