To study the effects of phosphate and zinc sulfate fertilizers application methods on water use efficiency and qualitative characteristics of corn underwater stress, an experiment was conducted in split plot factorial arrangement on randomized complete block design with three replications at research farm of the Bu Ali Sina University in 2014. Three levels of irrigation after 60, 90, and 120 mm...
In order to study the effect of on-farm seed priming using tap water and zinc sulfate solution with 0.03% zinc on yield and yield components of two intermediate maturing maize cultivars, a factorial experiment was carried out in complete randomized block design with three replications in Research Farm of Bu Ali University, Hamedan, Iran in 2011. Seed priming consisted of three levels (priming w...
بررسی عناصر روی و منیزیم بر خصوصیات زراعی و جوانهزنی بذر گندم نان (Triticum aestivum L. cv. Sivand)
In order to study the effect of zinc and magnesium on agronomic and seed germination traits of wheat (Sivand cultivar), the current study was carried out at Mahidasht Agricultural Research Station in Kermanshah over the years 2012 and 2013. The experiment was conducted as factorial based on completely randomized block design with three replications. The treatments consisted of four levels of zi...
Abstract In this study, effect of spraying nickel sulfate and urea on reproductive growth, yield and some qualitative characteristics of strawberry fruit were investigated. Rooted daughter plants of strawberry, cv. Pajaro, were grown in 3 L pots in greenhouse of College of Agriculture, Shiraz University. The established plants were sprayed, at 4-5-leaf stage, with nickel sulfate at concentrati...
OBJECTIVE To determine the inhibition effect of zinc sulfate on isolates of enteric bacteria. MATERIALS AND METHODS Mueller-Hinton agar containing different concentrations of zinc sulfate was prepared. Isolates used in this study were obtained from local clinics. They were Salmonella typhi, Salmonella groups A, B, C, D and E, Escherichia coli, Enterobacter, Shigella and Vibrio cholerae. Overn...
Reactions of zinc sulfate and (R)- or (S)-(1-phenylethylamino)methylphosphonic acid (pempH(2)) in the presence of 1,4-benzenedicarboxylic acid (H(2)bdc) result in homochiral enantiomers (R)- and (S)-[Zn(4)(pempH)(4)(bdc)(2)].2H(2)O (). When H(2)bdc is replaced by 1,2,4,5-benzenetetracarboxylic acid (H(4)btec), enantiomers (R)- and (S)-[Zn(3)(pempH)(2)(btec)(H(2)O)(2)].H(2)O () are obtained. Com...
After synthesis during the early log phase, the concentrations of ubiquinone and cytochromes did not vary during the growth cycle of Azotobacter vinelandii, when grown with either high or low aeration on nitrogen-free or urea-containing media. The level of aeration had no effect on the concentrations of the electron carriers synthesized, but affected the growth rate. On urea-containing medium, ...
The present research was accomplished on Phoenix dactylifera L. cv. Shahany to investigate the effect of macro and micronutrients on fruit quality and quantity. Treatments were urea (0.5, 1%), boric acid (1500, 2500 ppm), potassium sulfate (1, 2%) and zinc sulfate (300, 600 ppm). Higher and lower yield were obtained from H BO (1500 ppm) and control, respectively. The greater part of pulp weight...
background preterm premature rupture of membrane (pprom) prior to 37 weeks’ gestation is among the most common obstetrics problems, which is associated with prenatal mortality and several maternal and neonatal complications. history of pprom is a risk factor for recurrence. zinc has an important effect on the strength of membranes by affecting collagen [tensile] strength - a substance with immu...
Background: Oligoasthenospermia (OAS) is a condition characterized by low sperm count associated with low sperm motility. Medical treatment is not known in allopathic system for treatment of oligoasthenospermia. Homeopathic medicine is effective in more than 95% patients. Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology...
