The effect of Gibberellic Acid (GA3) on Jerusalem cherry (Solanum pseudocapsicum L.) was evaluated at pot cultivation conditions. This study was performed in factorial test based on complete random design plan and 4 repeats with 12 treatments. The main factor was included spraying, drip and spraying + drip. Secondary factor was included concentrations of GA3 at 0, 100, 200 and 400 mg.L-1 levels...
Background and Objectives: Humic substances belong to a group of micro molecular of organic substance with different molecular weight produced by reaction of biological and geochemical process. They are known as one of the main prefabrications of disinfection byproducts. This study aimed at investigating the efficacy of (ZnO) nanoparticle under UV/ZnO radiation in removing humic acid. Materia...
one of the most important issues affecting environmental health and sustainable food production is application of organic fertilizers instead of chemical fertilizers. this study set out to investigate the effect of application of soil humic acid and fulvic acid on barley plant. to this end a factorial experiment was carried out on the basis of randomized complete block design with four replicat...
Nutrition of fruit trees during the growing season plays an important role in growth, fruitfulness and fruit quality. Given the increasing application of bio-stimulators as one of the most important approaches towards sustainable agriculture, some bio-stimulators were applied to elucidate their effects on vegetative characteristics and leaf mineral content of apricot trees cv. “Shekarpareh” in ...
In order to evaluate biofertilizer, nitrogen and humic acid effect on quantitative and qualitative traits of chickpea (ILC 482 line) this research was carried out at the Agricultural Research Field of Kurdistan University, Sannadaj, Iran. A factorial experiment was conducted based on a randomized complete block design with three replications. Experimental treatments included three levels of lea...
Introduction: Humic acids have adverse effects on the water quality, then should be removed from water resources. The aim of this study was to evaluate the effect of nitrate as a radical scavenger for removal of humic acid from aqueous solutions by electron beam irradiation. Materials and Methods: In this study, after preparation of stock humic acid solution in alkaline condition, different con...
Culture medium and nutrition are two important factors in determining the quantity and quality of greenhouse products. Accordingly, a factorial experiment was conducted based on completely randomized design on strawberry (cv. Aromas) in the greenhouse of Department of Horticulture, University of Kurdistan, Sanandaj, Iran. The first factor was two culture media (mixture of perlite and cocopeat w...
In order to investigate the effect of humic acid and nano-calcium chelate on Gerbera jamesonii cv. Dune, an experiment was performed as factorial based on a completely randomized design with two factors and three replications in hydroponic conditions. First factor was included: humic acid in 4 concentrations of 0 (control), 500, 1000, and 2000 mg L-1 as drench and the second factor: nano-calciu...
humic acid as an organic substance can bound heavy metals. it is a best way of decreasing the hazardous effect of heavy metals on plants and thereby on humans. a factorial experiment was conducted in a completely randomized design of seven replications. the treatments consisted of three cadmium levels (0, 2 and 4 mgl-1), and three humic acid levels (0, 100, 1000 mgl-1) added to nutrient solutio...
تأثیر اسید هیومیک بر کارایی گیاهپالایی سرب در خاکهای آلوده توسط گیاه افسنتین (Artemicia absantium)
Because of the undesirable effects of lead on soil properties and human health, evaluation of its remediation methods seems to be essential. In order to evaluate the effect of humic acid (HA) on the decontamination of lead (Pb) spiked-soils in the presence of wormwood plant (Artemicia absantium), an experiment was carried out in a completely randomized block design with three replications. Ex...
