the effect of different fertilizing systems and drought stress during grain development on grain minerals of barley (hordeum vulgare l.) was studied in field experiments on a clay-loamy soil during 2007 and 2008 growing seasons. the treatments consisted of three irrigation regimes (main plots) of: non-stressed (ns, normal irrigation continued until the end of plant physiological maturity), ...

Methane-oxidizing bacteria (methanotrophs) in the soil are a unique group of methylotrophic bacteria that utilize methane (CH4) as their sole source of carbon and energy which limit the flux of methane to the atmosphere from soils and consume atmospheric methane. A field experiment was conducted to determine the effect of nitrogen application rates and the nitrification inhibitor dicyandiamide ...

to evaluate the effect of gamma rays on the seeds and amounts of nitrogen on growth and yield of chamomile (chamomilla recutita synonym matricaria chamomilla), a factorial experiment was conducted based on randomized complete block design with three replications at the research farm of agriculture college of shahid-beheshti.-urmia in 2010. treatments were gamma rays from cobalt-60 on chamomile ...

The application of organic fertilizers alone or in combination with bio-fertilizers is important for sustainable agriculture, healthy agricultural production and restoring soil quality. Compost, vermicompost and mycorrhiza amendments could improve soil quality and plant yield. However, little is known about their impact on yield and quality of European borage (Borago officinalis L.). To evaluat...
