The effect of compost and humic acid in mobility and concentration of cadmium and chromium in contaminated soil were investigated. Experiment was carried out with three levels of soil cadmium and chromium and two organic matters (compost and humic acid). The study was performed in a randomized complete block design with 3 replicates. Results indicated that application of organic substances enha...

The interactions between earthworms and microorganisms can produce significant quantities of plant growth hormones and humic acids which act as plant regulators. Experiments were designed to evaluate the effects of humic acids extracted from vermicompost and compare them with the action of commercial humic acid in combination with a commercial plant growth hormone, indole acetic acid (IAA) whic...

this experiment was conducted as randomized complete block design with three replications in 2012 at university of zabol. experimental treatments included phosphorus fertilizer at three levels of 0, 100 and 200 kg.ha-1 as the first factor and foliar humic acid at four levels of 0, 750, 1500, 2250 g.1000 l water as the second factor. results showed phosphorus treatment had significant effect on ...

introduction & objective: in vitro studies shown the effect of zinc sulfate on healing of ulcers but limited in vivo studies have been done to demonstrate this effect in human. this study was conducted to investigate the effect of zinc sulfate on peptic ulcer disease materials & methods: this is a double blind randomized clinical trial study. we studied people who referred to endoscopy clinic i...

Annexin A5 (anxA5) is abundantly present in seminal plasma, however, its endogenous function in seminal plasma is not known. Recently, we demonstrated that folic acid and zinc sulfate intervention increased sperm count. To explore the involvement of anxA5 in human (sub)fertility, we measured anxA5 concentrations in seminal plasma, using sandwich ELISA, before and after folic acid (5 mg/day) and...

The aim of this work is to explore the suitability of the complementary use of mass spectra and the corresponding statistical analysis (principal components-Pareto analysis (PCA) and discriminant analysis (DA)) of these spectra to differentiate diverse humic samples as a function of their structural and conformational features. To this end, the mass spectra of humic samples belonging to the mai...

In this study effect of irrigation managements including irrigation after 100 and 200 mm pan evaporation as normal and deficit irrigation respectively was investigated in Roselle plants. Effects of humic acid (including 0 and 4 kg ha-1) and mycorrhizal inoculants (including Glomus versiforme (GV) and Rhizophagus irregularis (RI)) were also studied on growth, yield and mycorrhizal symbiosis inde...

in order to study the effect of  foliar application of zinc and iron on germination of soybaen seed under different level of irrigation, an experiment was conducted in 2009 at shahrekord agricultural research center. main factor was including of four levels of drought stress as irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from class a evaporation basin) and sub factor was inc...

in order to evaluate effects of water stress and foliar application humic acid on quantities and qualitative in borage, a field experiment was conducted as a split plots design with three replication in 2012 at agricultural research station, university of zabol. water stress treatments included control or 90 percent of field capacity (w1), 70 percent field capacity (w2) and 50 percent field cap...
