Effect of Soil Application of Humic Acid and Fluvic Acid on Agronomic traits of Barley
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...
متن کاملEffects of Humic and Fulvic Acids on Some Physiological Characteristics of Two Ornamental Plants of Granium (Plargonium spp.) and Scindapsus (Scindapsus spp.)
Humic acid and fulvic acid are natural and organic materials, which are derived from various sources such as soil organic matter (humus), soil, peat, oxidized lignite and coal. In order to evaluate the effect of humic substances on physiological characteristics of two ornamental plants of granium (Plargonium spp.) and scindapsus (Scindapsus spp.), an experiment was conducted as 4×4 factorial, b...
متن کاملThe Effects of some Inorganic-, Synthetic- and Organic-Fertilizers on the Vegetative Growth and Iron Content in Pistachio cv. Ghazvini under Alkaline Conditions
In the current research, the effects of some organic fertilizers as fulvic and humic acids on the vegetative growth of pistachio seedlings in a semi-hydroponic culture containing Fe-EDDHA (as a synthetic fertilizer) and FeSO4 (as an inorganic fertilizer) were investigated. The alkalinity is recognized as a main problem in pistachio orchards, therefore the pH of nutrient solution was ...
متن کاملتأثیر مواد هومیک و قارچ میکوریز بر جذب آهن و روی و برخی خصوصیات رشدی سویا در شرایط گلخانه
Iron (Fe) and zinc (Zn) deficiency has been known as a key factor in limiting crop production in calcareous soils of arid and semi-arid regions. Since the components of organic matter can change Fe and Zn availability, this study was conducted to investigate the effects of humic treatments including humic acid (HA), fulvic acid (FA), vermicompost (Verm), HA+FA and HA+FA+Verm and mycorhiza inocu...
متن کاملEffect of ethanol and humic acid foliar spraying on morphological traits, photosynthetic pigments and quality and quantity of essential oil content of Dracocephalum moldavica L. Amirhossien Samadimatin1 and Abbas Hani2*
In order to study the effects of humic acid foliar spraying on morphological traits, photosynthetic pigmentation, and essential oil content of Dracocephalum moldavica, a factorial experiment was conducted based on a randomized complete block design with three replications in Saveh. The investigated factors included the use of humic acid at four levels 0 (control), 200, 400, and 800 mg/L and eth...
