nitrogen and phosphorus are two necessary macronutrients for plant growth and yield. these two elements now will be added to soil by chemical fertilizers. this research has been carried out based on randomized completely block design with three replications at markazi provience agricultural research station, iran, during growing season of 2004-2005 to evaluate the effects of azotobacter chrooco...

Zinc sulfate is an inorganic compound: the sulfate salt of zinc and a good source of zinc ions. The molecular 40 formula for zinc sulfate is ZnSO4. A graphic representation of the structure of zinc sulfate is shown in figure 1 41 (Pubchem, 2014). Zinc sulfate appears geologically as a white crumbly salt efflorescence known as “goslarite.” 42 Goslarite, the heptahydrate of zinc sulfate was first...

to evaluate the effect of on-farm seed priming and methods of zinc sulfate application on seed emergence properties, yield and yield components of two corn cultivars, an experiment was conducted as factorial in randomized complete block design with three replications during 2012 at research farm of bu-ali sina university, hamedan. first factor was methods of zinc sulfate application containing ...

statement of the problem : geographic tongue is characterized by loss of filliform papillae in an erythematous area with keratotic borders. it vanishes after a while and reappears in another area. it is relatively common and is most seen among females. considering such problems as pain, burning sensation and sharp pain in tongue, decreasing of taste sensation, cancer phobia and esthetic problem...

zinc has previously been reported to alleviate salinity stress in plants. in this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in glycine soja. the plants subjected to a series of salinity levels (nacl concentration of 0, 100, 200, and 300 mmol l-1), a...

BACKGROUND: Mineral nutrition is one of the most important factors affecting plant growth and productivity, also growth analysis is a way to assess what events occurs during plant growth. OBJECTIVES: The goals of this study were to investigate the effect of different level of nitrogen fertilizer and zinc sulfate on growth indices of Green bean. <str...

Growth regulators such as biostimulants can promote positive changes in the plant physiological processes, being alternatives to help seedlings development with high quality. Therefore, this study aims evaluate characteristics of industrial tomato and pepper fertilized biostimulants. The experimental design was a randomized block six treatments four replicates. were: fertilizers different nutri...

a b s t r a c t   zinc deficiency in man is characterized by skin lesion, alopecia and has been linked to growth retardation and mental disturbance. for supplementation purposes zinc is currently presented as its sulfate salt, from which uptake by the body is poor, necesseting the administration of high doses. this leads to a range of unpleasant side effects. in order to increase the bioavailab...
