Essential oils of Ocimum ciliatum were extracted by hydrodistillation at different phenological stages, in order to determine possible differences and similarities of the oil yield and chemical composition of them.

Essential oil yields were 1...

The effect of different sowing dates on growth, development, morphological characteristics, yield, oil content and fatty acid composition of Linum usitatissimum L. was evaluated in semi-arid condition of Iran. An field ...

-free treatments, respectively. The results revealed that N, P and K contents in weed tissues ignificantly

increased with increasing weed-infested periods during both years of the experiment. The reduction in grain and oil yield due to longer periods of weed...

recorded with CO2 enrichment. When CO2 was elevated from 380 to 1050 ppm, the values of height (24.3%), SPAD reading (2.7%), essential oil yield (26.3%) and final yield (65.3%) were increased, unlike, stomatal conductance (35.2%) and essential oil...

earlier sowing date resulted in higher seed yield, oil content and oil yield in either year. Based

on the results of the fatty acid analysis by gas chromatography (GC), fifteen fatty acids

were observed in castor oil...
