abstract balanced nutrition and soil organic mater are among most important factors affecting yield and quality of grape (vitis vinifera cv.peykani). humic acid as an organic acid derived from humus and other organic sources, in accompany with zinc, and acetic acid can reduce deficiency symptoms in grape. to study the effects of zinc, humic acid and acetic acid on yield and yield components, an...

This research was conducted to evaluate effect of potassium and iron fertilizers on agro-physiological traits affected different irrigation regime of corn in Shahryar (Tehran province, central of Iran) via a split-split plots arrangement based on randomized complete blocks design with three replications during 2015. The main plot included different irrigation regime (Normal irrigation and stop ...

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), app...

The objective of this study is to identify an adequate zinc (Zn) foliar spray concentration which corrects Zn deficiency without disrupting other plant mineral contents, enhances plant growth, and thereby corn silage yield when grown on sandy soil. A field experiment was conducted using five Zn foliar spray concentrations (w/v): 0.03%, 0.07%, 0.10%, 0.14% and 0.18%. Zn sulfate (ZnSO4. 7H2O) was...

plants are the most sources for cadmium enters to human food and this element in food regime may be a serious threat to human health. thus, the effect of azotobacter inoculum (azotobacter chroococcum), mycorrhiza fungi (glomus intraradaices) , zinc sulphate and urea on cadmium convertation and growth parameters of fenugreek medicinal plant (trigonella foenum gracum l.) in cadmium polluted soils...

in order to evaluate the efficiency of inoculation of chickpea seeds with mesorhizobium and application of nitrogen and zinc on yield and yield components of rainfed chickpea an experiment was carried out in research station of shirvan-chardavel, ilam. the experiment was conducted in randomized complete block design (rcbd) with six treatments including mesorhizobium inoculation, nitrogen (40 kg...

Lack of available water in arid and semi-arid regions has a negative effect on the production of soybean (Glycine max L.). Nano zinc chelate (ZnO) has the potential to alleviate this issue through overcoming zinc deficiency and thereby improve plant function. Therefore, to evaluate the effectiveness of ZnO application on soybean in drought stress conditions, a split-plot experiment based on ran...
