the saffron understanding the factors that increased the quality and quantity of product in order to achieve optimum performance it is important, in this regard, the use of fertilizers and different densities corm are the most important factor. in this regard, an experiment in 1394 to factorial design in a randomized complete block design with three replications in the village davoodabad locate...

Background: Nitrogen is the most important nutrient requirement for plants. Nitrogen supplying affected the leaf area, carbon fixation, glandular trichomes formation, ATP and NADPH content which resulted to the terpenoids biosynthesis enhancement and essential oils accumulation. Objective: This study was aimed to evaluate changes of essential oil content and components by use different levels ...

Background and Aims: Formaldehyde, a colorless aldehyde with pungent odor, has negative effects on systems of the body. Considering, there are a little data about protective substances against kidney damage induced by formaldehyde, the aim of the present study was to examine the effects of different doses of N-acetyl cysteine on biochemical and histopathological parameters in k...

One effort to reduce nitrogen loss is make the fertilizer in a form of slow-release. SRF method can be done conventionally based on centrifugal force. Nitrogen release from UZA fertilizers generally decreased during incubation period. Urea slow-release combination zeolite and humic acid applied soil media rate nitrate release. In this case, it necessary identify effect ready modifying acid. Inc...

A field experiment was designed to study the effects of nitrogen (N) source and urease inhibitor N-(nbutyl) thiophosphoric triamide (NBPT) or nitrification inhibitor dicyandiamide (DCD) on nitrous oxide (N2O) emission and N use efficiency (NUE) in a sandy loam soil. Six treatments including no N fertilizer (control), N fertilizer urea alone (U), urea plus NBPT (NBPT), urea plus DCD (DCD), urea ...
