effects of various fertilizers such as farmyard manure (fm), urea, and plant growth promoting rhizobacteria (pgpr, including the genera azotobacter and azospirillium) were checked on yield, fatty acids, protein, and oil contents of sunflower. a two-year field experiment was conducted in a semi-arid region in iran in 2007 and 2008. the experiment was a split plot in a randomized complete block d...

Microwave pyrolysis of distillers dried grain with solubles (DDGS) was investigated to determine the effects of pyrolytic conditions on the yields of bio-oil, syngas, and biochar. Pyrolysis process variables included reaction temperature, time, and power input. Microwave pyrolysis of DDGS was analyzed using response surface methodology to find out the effect of process variables on the biofuel ...

the genus hypericum is one of the most important medicinal plants that contain 17 species in iran, three of them are endemics. this paper reports the essential oil composition of eight hypericum species from iran. the essential oil analysis of a number of the studied plants has already been reported but their report from iran may be valuable for scientists.  samples collected from different pla...

introduction sunflower (helianthus annuus l.) is one of the most important oil crops in the world. iran is climatically regarded as an arid and semi-arid region in the world, where the lack of precipitation and its inappropriate distribution, high temperature and extensive evaporation makes the irrigation the main way for meeting plants water demand. hence, studying the effect of irrigation on ...

to assess moisture stress tolerance at the reproductive growth stage in 11 promising genotypes of spring rapeseed (brassica napus l.), two field experiments were conducted in two growing seasons (2008-2010) at the agricultural research center of safiabad, dezful, iran. genotypes were sown under two non-stress (well-irrigated) and moisture stress (irrigation ceased at flowering) conditions using...
