the study was carried out to evaluate the effects of soil application of humic acid and calciumon morpho-physiological traits and na+, mg2+, ca2+ uptake of pistachio seedling (akbari) grown under salt stress.  a completely randomized design was used with four replications in greenhouse conditions. the experimental treatment consisted of four levels of humic acid (bis humic) (0, 4, 8 and 12 gr k...

to evaluate the effect of slow release fertilizer and humic acid on quality of new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with 15 treatments and three replications. treatments were slow release fertilizer (12-11-18-2.7mgo-8s) in five levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid in three levels (0, 2 and 4 kg/m3) that mixed with medium cul...

in order to evaluate the effect of humic acid and zn on the grape yield and mineral concentration, a factorial experiment was conducted based on a randomized complete block design with three replications. the study was done on 20 years old grapevines in the farsan region from chaharmahal and bakhtiari province in 2013-2014. each of the factors, humic acid and zinc sulfate, were applied in three...

abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits s...

In a sustainable agriculture system, application of the fertilizers which are nature friendly and suitable for plants is essential. This becomes more important when dealing with medicinal plants. Therefore, a factorial experiment in a randomized complete block design with three replications was set up in the 2012-2013 on Nigella sativa L. Treatments were nano­fertilizer (Pharmks®) (at 2 levels ...

The impact of humic acid fouling on the membrane transport of two pharmaceutically active compounds (PhACs) - namely carbamazepine and sulfamethoxazole - in forward osmosis (FO) was investigated. Deposition of humic acid onto the membrane surface was promoted by the complexation with calcium ions in the feed solution and the increase in ionic strength at the membrane surface due to the reverse ...

introduction roselle (hibiscus sabdariffa l.) as a medicinal plant belongs to the malvacea family. their active ingredient increases under water stress. humic acid bacteria derived from humus and other natural resources have hormonal effects and can improve nutrient absorption to enhance performance especially under stress conditions . materials and methods this experiment was conducted in the ...

To study the impact of growth factor bacteria , humic acid  and alga extract in drought stress condition  a test is established in form of completely random blocks  and spilt plot  in 4 replications  in a field in Mahallat in Arak  province in 1389. Two primary plots including irrigation and stress  and secondary  plots including  growth factor bacteria ,humic acid  and  alga extract, Ascophylu...
