Abstract To study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. Analysis of variance showed considerable variation among cultivars. Water stress reduced all of the studied morphological characteristics, espe...

The optimal management of prolonged priapism for patients with sickle cell anemia (SCA) has not been established. We prospectively studied in an outpatient setting the efficacy and safety of a procedure that employs aspiration of blood from the corpora cavernosa and irrigation with a dilute epinephrine solution under local anesthesia to relieve priapism in young patients with SCA. If hydration ...

Limited precipitation restricts crop yield in the North China Plain, where high level of production depends largely on irrigation. Establishing the optimal irrigation scheduling according to the crop water requirement (CWR) and precipitation is the key factor to achieve rational water use. Precipitation data collected for about 40 years were employed to analyze the long-term trend, and weather ...

Crop production is a process of multiple inputs (water and nutrients, etc.), and the relationships between the inputs and crop yield are very complex. This study used a model for data envelopment analysis (DEA) to evaluate the efficiency of irrigation-fertilization schemes for winter wheat in North China. The field experiments were conducted at the Xiaohe Irrigation Experiment Station in Centra...

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), ...

The effect of four different levels of irrigation periods, including normal irrigation, irrigation after 100, 150, and 200mm evaporation, with three different bio-fertilizer including control, Mycorrhiza, and Rhizobium were investigated on morphological and yield traits of guar. The experiment was conduct in form of split-plot design with irrigation periods as main plots and bio-fertilizers as ...

Background: Endoscopic third ventriculostomy (ETV) has become the standard surgical procedure for treatment of non-communicating hydrocephalus. The aim of this study is to report our results over the past ten years with reference to perioperative complications of ETV with a review of some specific anesthetic issues. Methods: The computerized database (in the Department of Neurosurgery) and the ...

Although the term precision irrigation is now quite widely used, often to mean drip irrigation, there is no commonly accepted definition or conceptualisation of the term, and no cohesive framework to guide research, development or adoption. This paper is reporting on a review of precision irrigation funded by NPSI. This review is considering the role of current irrigation application technologi...

a split plot experiment based on complete block design with three replications was carried out to evaluate the effect of irrigation and potassium fertilizer on yield and yield components of green beans, in 2011 at ahvaz. two levels of irrigation (normal irrigation and drought) and four levels of potassium sulfate fertilizer (0, 25, 50 and 100 kg ha-1) were evaluated in this study. the results o...

to evaluate the effects of phosphate solubilizing bacteria and chemical phosphorous fertilizer on turnip (brassica rapa) forage yield under limited irrigation regimes, a field experiment was conducted in research farm of college of agriculture and natural resources, university of tehran, in karaj/iran during 2009 growing season. the experimental treatments were arranged as split plots. five lev...
