New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...

In order to study of the effect of seed inoculation with PGPR on nitrogen and phosphorus use efficiency of spring wheat in different levels of nitrogen and phosphorus fertilizers, an experimental was conducted at the Research Farm of Mohageh Ardabili University, Ardabil, Iran during 2012 year. The combination of nitrogen fertilizer in three levels (0, 40 and 80 kg N/ha as urea) and phosphorus f...

The effect of nitrogen (N) fertilizer on switchgrass biomass production has been evaluated in a number of locations on a small-plot scale; however, field-scale information regarding switchgrass response to N and N use efficiency (NUE) in different regions of the USA is limited. Switchgrass was planted in South Dakota (SD), New York (NY), Oklahoma (OK), and Virginia (VA) in 2008 and in Iowa (IA)...

Background Wastewater from sewage treatment plants contains high levels of nutrients, which can be used for plant nutrition. Classical wastewater use complex microbial consortia autotrophic and heterotrophic microorganisms biological treatment. Certain microalgae (e.g., species the genera Chlorella, Scenedesmus, Pediastrum) accumulate nutrients very effectively. Aims We investigated potential b...

investigation of various irrigation methods and intercropping are effective strategies for increasing water use efficiency and improve crop production. a field experiment conducted to study the effects of alternate furrow irrigation on quantitative and qualitative characteristics of forage corn with annual alfalfa cropping under its canopy in ilam climate conditions. experiment carried out as a...
