this study examined the environmental impacts of irrigated and rainfed barley agroecosystems of iran based on nitrogen levels by using lca methodology during 1999-2013. four steps includung goal definition and scoping, inventory analysis, life cycle impact assessment and integration & interpretation were considered. impact categories were acidification, eutrophication and global warming. functi...

Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...

this research was conducted to study the effects of water deficiency stress, nitrogen application rates, and plant population on water use efficiency and nitrogen of oily sunflower in 2007-2008 agriculture and research center of west-azerbaijan. the study was consisted split-split-plot experiments using randomized complete block design with 3 replications. the factor main was consisted irrigati...

a field study was conducted to determine the integration of split n fertilization and herbicide application on weed management and wheat (triticum aestivum l.) yield in shiraz, iran, in 2005/2006 and 2006/2007 growing seasons. the experimental design was split plot with four replications. main factors consisted of n timing and splitting, and sub plots included iodosulfuron–methyl–sodium plus me...

in order to study the effects of wild mustard density on grain yield and yield components of canola cv. hyola 401 under different rates of nitrogen fertilizer, a field experiment was conducted in 2011-2012. the layout was split-plot in a completely randomized block design and three replications. main-plots included four levels of nitrogen (0, 70, 140 and 210 kg ha-1) and sub-plots consisted of ...

BACKGROUND Peanut consumption favorably influences satiety. This study examined the acute effect of peanut versus grain bar preloads on postmeal satiety and glycemia in healthy adults and the long-term effect of these meal preloads on body mass in healthy overweight adults. METHODS In the acute crossover trial (n = 15; 28.4 ± 2.9 y; 23.1 ± 0.9 kg/m2), the preload (isoenergetic peanut or grain...

Crossbred steers (n = 7; 400 kg BW), fitted with T-type cannulas in the duodenum and ileum, were used to examine the effects of processing method, dry-rolled (DR) vs. steam-flaked (SF) sorghum grain, and degree of processing (flake density; FD) of SF corn (SFC) and SF sorghum (SFS) grain on site and extent of DM, starch, and N digestibilities and to measure extent of microbial N flow to the duo...
