Irrigation, salinity and nitrogen (N) are the three major limiting environmental factors inmaize yield potentials especially in arid and semi-arid regions. An integrated water and N MaizeSimulation Model (MSM) was modified for salinity conditions using 2009-2010 fieldexperiments data in southwest of Iran. Irrigation levels were: I1=1.0ETc+0.25ETc as normalleaching amount, I2=0.75I1 and I3=0.5I1...

Nowadays, applying soil amendments is one of the most important ways to cope with water shortages and improve soil physical properties. In this regard, a greenhouse experiment was conducted to study the effect of different levels of irrigation water and wheat straw biochar on physical and chemical properties of a sandy loam soil, after harvesting faba bean. The experiment was performed with 5 b...

due to the lack of fresh water resources, the use of saline water for the production of plants such as wheat and kochia is inevitable. to sustain production, the effect of saline water on the plants and soil in each region must be studied. therefore in this paper, the effects of irrigation with saline water to produce plants such as wheat and kochia, as well as changes in the soil salinity prof...

The clearing of natural vegetation and irrigation for farming have resulted in rises in the level of groundwater. The rising water table brings salt previously stored deep in the soil profile to the surface, leading to secondary salinisation. Whilst many ecosystems are affected by secondary salinisation, wetlands are considered to be particularly vulnerable because of their low-lying position i...

PURPOSE The aim of the present study was to evaluate and to compare the antibacterial effects of various irrigation solutions against Staphylococcus aureus (S. aureus) in human root canals. MATERIALS AND METHODS 120 single-root mandibular premolar teeth were selected. The teeth were prepared and sterilized. S. aureus was incubated in the root canals and kept at 37°C for 24h. The infected root...

Objectives: We aimed to investigate the efficacy of intraabdominal irrigation with warm saline on pain management and gastrointestinal functions in the postoperative period among patients that underwent cesarean section under spinal anesthesia. Material and methods: Ninety-one women who underwent cesarean section under spinal anesthesia were enrolled in our study. Patients were allocated to eit...
