a pot experiment was conducted to evaluate the effect of foliar spray of salicylic acid (0, 50, 100 ppm), ascorbic acid (0, 100, 200 ppm) and thiamine (0, 50, 100 ppm) on vegetative growth, flowering and photosynthetic pigments of marigold (calendula officinalis l.) plants at greenhouse of sb university of kerman, iran. results showed that application of salicylic acid and thiamine increased nu...
Due to recent droughts in Iran and other parts of the world and consequently limited water resources, tending to aquaponic system, in which fish and plants grow together, is a logical and practical method. For this reason, in the current experiment, possibility of mint planting in aquaponic system and the effects of applying nano-fertile fertilizer containing 60% humic acid on its growth was in...
In order to study the effects of water deficit and foliar application of salicylic acid and spermine on dry matter production and biochemical and morphological treats of Echinacea purpurea, a split plot experiment was conducted based on randomized complete block design with three replicated during 2016- 2017 growing seasons at research field of Institute of Forests and Rangelands, Iran. In this...
improve forage quantity and quality using organic and biological fertilizers production of important needs in dryland farming systems of the country. in this study the effects of foliar application of four different combinations of amino acid four different time steps were germinated plant growth, stem elongation, flowering and spraying all three steps above with the control treatment was carri...
training systems and calcium foliar application can improve apple fruits pigmentation by changing mineral compositions. in this study, effect of foliar application of calcium chloride with different concentrations (0, 0.75, 1.5 and 3 g l-1) over 2, 4 and 6 weeks before harvest time on fruit mineral nutrient composition and colour values of apple cvs. gala and delbarestival which trained in thre...
Reducing iron solubility in calcareous soils causes iron chlorosis symptoms in the plant. In order to investigate the response of M. scutellata to direct and indirect iron deficiency, a factorial experiment was conducted in a completely randomized design with three replications. The experimental factors included three levels of lime (0, 4 and 8%) and five levels of Fe (0, 5 and 10 mg Fe Kg soil...
A serious problem in cultivation of ornamental plants is a lack scientific and applied program in fertilization, so that the plant nutrition focused on growth medium. A randomized completely design with 8 different fertilization methods with the use of ammonium sulphate, potassium sulphate, di ammonium phosphate, ferrilene and kristalon was conducted in three replications in a greenhouse of Cha...
These field trials were carried out to investigate the effect of various zinc (Zn) fertilizer application treatments on grain yield of some spring (Isfahan and Neishabour) and winter wheat cultivars (Mashhad and Jolge-e-Rokh) with different Zn efficiency during 2009-2010 growth seasons. Five Zn fertilizer treatments were applied including: no added Zn (control), soil application of Zn-sulfate, ...
Background: Biotic and abiotic elicitors produce secondary metabolites and alter physiological traits of the plants by affecting some of the mechanisms within the plant cells. Objective: This study was aimed to investigate the effects of different concentrations of spherical nano-carbon and salicylic acid on physiological traits and paratolenolidae content in Feverfew. Methods: This research ...
