considering the importance of medicinal plants growth and biological application of fertilizers with sustainable agricultural production in order to eliminate or reduce chemical input to achieve desirable and sustainable quality, an experimental research was  conducted based on a randomized complete block design with two factors of chemical nitrogen (46% urea nitrogen) at  two levels (zero, 25 ...

abstract field experiment was carried out at the ferdowsi university research field, mashhad, iran during 2006-2007, to determine how much effective the n-fertilization is, to find out the most suitable plant density which could be used in chamomile (matricaria chamomilla l. asteraceae) to increase the yield of anthodium flowers and content of essential oil. the experimental design was as two f...

differentiation among populations of the iranian teucrium polium l.was analyzed on the basis of morphological and phytochemical variability, to evaluate the level and distribution of diversity among four distant populations from arid, semi-arid, and sub-humid regions of fars province. morphological analysis included 11 characters related to the plant, leaf, and stem morphology. analyses of vari...

in iran, more than 90% of raw materials including oils and oil seeds are provided through import. camelina sativa l. as an oilseed crop, belongs to brassicaceae family, has been shown in several experiments that need very little water and resistant to chilling injury than other plant oils, especially canola. this experiment was conducted at research station of campus of agriculture and natural ...

18 Producing organic fish diets requires that the use of both fish meal and fish oil is minimized 19 and replaced by sustainable, organic sources. The purpose of the present study was to 20 replace fish oil with organic oils and evaluate the effects on feed intake, feed conversion 21 ratio (FCR), daily specific growth rate (SGR) and nutrient digestibility in diets in which fish 22 meal protein ...

Aedes aegypti and Anopheles gambiae are two mosquito species that represent significant threats to global public health as vectors of Dengue virus and malaria parasites, respectively. Although mosquito populations have been effectively controlled through the use of synthetic insecticides, the emergence of widespread insecticide-resistance in wild mosquito populations is a strong motivation to e...

yarrow (achillea spp.) belonging to the family of asteraceae with useful properties, such as anti-diaphoretic, anti-hemorrhagic, anti-inflammation, anti-biotic, anti-fungal, anti-bacterial, carminative and anti-oxidant effects. the present investigation assessed the morphological diversity of achillea aucheri, which is indigenous plant from damavand mountain of iran. the samples were collected ...

in order to investigate the influence of bio- and chemical fertilizers on growth parameters and essential oil of fennel (foeniculum vulgare miller.), an experiment based on randomized complete blocks design with five treatments and three replications was carried out. arbuscular mycorrhizal fungi (strain sebacina vermifera) and phosphate dissolving bacteria (genera peseudomonas) were applied as ...

in in order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (rcbd) with 4 replications in saat-loui agricultural station of west azerbaijan province. in this research, the first factor (a) contained two levels 20 and 40 cm inte...

Cyperus scariosus R.Br. (Nagarmotha) is pestiferous perennial, delicate slender sedge found wildly in various parts of the country, especially in damp or marshy areas and collected wildly for extraction of its essential oil using steam distillation. The rhizomes of C. scariosus possess pleasant aromatic odour, the essential oil is used as anti-inflammatory, anti-microbial and anti-fungal agent ...
