Increasing attention is being paid to use of organic fertilizers such as manure and vermicompost which can increased yield and protect the environment. Replacing chemical fertilizers with manures has the benefit of low production cost and imparts beneficial effects on soil. Then an experiment was conducted during 2013 to measure effects of organic fertilizers on essential oil of dill (Anethum g...

background & aim: the world production and consumption of essential oils and perfumes are increasing very fast. lippia citriodora h.b.k. is an herbal species mainly used as a spice and medicinal plant. endogenous levels as well exogenous application of plant growth regulators (pgr) could affect essential oil production and chemical compositions. experimental: to study the effect of exogenou...

inhibitory effects of lavandula angustifolia and zataria multiflora essential oils were evaluated on reproduction and f1 progeny production of callosobruchus maculatus. insect’s culture and bioassays were conducted at 29 ±1ºc, 60±5% rh and dark condition. essential oils were taken by hydrodistilation. the results indicated that there was a negative and significant linear relationship between re...

four in vitro experiments (exp.) were conducted to evaluate lavender essential oil (leo) effects at 0 (control), 250 (low dose), 500 (medium dose), 750 and 1000 µl per l(high doses) of incubation medium on rumen gas production kinetics (exp.1), ruminal digestibility and fermentation (exp.2), methane production (exp.3) and rumen acidosis (exp.4). the asymptote of gas production (a) increased qua...

BACKGROUND The leaves of Ocimum basilicum L. (basil) are used in traditional cuisine as spices; its essential oil has found a wide application in perfumery, dental products as well as antifungal agents. AIM To assess the chemical composition as well as the in vitro antifungal activity of O. basilicum L. essential oil against Aspergillus flavus fungal growth and aflatoxin B1 production. MATE...

Background & Aim: Ziziphora L. genus belongs to the Lamiaceae family, which has important medicinal and aromatic plant species. In current study, essential oil chemical compositions of two Ziziphora L. species (Z. tenuior L. and Z. clinopodioides Lam.) were investigated. Experimental: The flowering branches of Z. tenuior and Z. clinopodioides</e...

Aim: Present study was conducted to examine the modulatory effect of different essential oils on rumen fermentation pattern in vitro using wheat straw based diet (concentrate: wheat straw 50:50). Materials and Methods: Four essential oils i.e. cinnamon, garlic, oregano and rosemary oils were tested at concentration of 0, 30, 300 and 600 mg/litre (ppm) of total culture fluid using in vitro gas p...
