تأثیر غلظت پتاسیم محلول غذایی بر لیکوپن، ویتامین ث و ویژگی های کیفی گوجه فرنگی آلبالویی در شرایط شور
Potassium (K) has a special place in improving the quality of agricultural products. To evaluate the effect of K concentration in nutrient solution on lycopene content, vitamin C and qualitative characteristics of cherry tomato in NaCl salinity conditions, an experiment was carried out as a completely randomized design with five treatments and three replications at university of Tabriz, Tabriz,...
hydroponics technique accompanied by adjustment of nutrient solution seems to optimize crop production and help in establishing sustainable agriculture. in recent years, the greenhouse production of cucumber has been increased in iran, however there are just a few proper nutrient solutions employed in growing the crop. in line with this, an experiment was conducted to find the effect of various...
The aim of this study was to determine the efficacy of pectin solution, which increases the viscosity of liquid nutrient, for prevention of gastro-esophageal reflux in comparison with half-solid nutrient. The subjects were 10 elderly patients undergoing percutaneous endoscopic gastrostomy feeding. Twenty-four-hour esophageal multichannel intraluminal impedance and pH testing was performed durin...
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...
Plants absorb nutrients needed for plant type, growing season, depending on soil and yield. Absorb of nutrient 30-90 percent depends management practices in the use of fertilizer. Can be used fertilizers in most cases soil and for foliar feeding can be quickly absorbed into the plant at the proper levels of nutrition in cucumber. In this experiment, was used a split plot in a randomized complet...
Hydroponic leafy green production offers high productivity and quality of crops but requires good management pH electrical conductivity (EC) to optimize the nutrient uptake. Nutrient solution is typically managed between 5.5 6.5, whereas lowering more acidic range (e.g., <5.0) can potentially mitigate problematic waterborne diseases. Plant response low species specific generally involves dir...

climatic conditions of guilan have caused to develope azolla growth in wetland and ponds. regarding environmental problems of azolla accumulation, a study was conducted to investigate impact of composted azolla with nutrient solution on the growth of dracaena in replacement of peat in ornamental plants and flower research station, lahijan, iran. the control treatment was a 2:1 ration of peat: p...
To study the effect of different concentrations of potassium in thenutrient solution and water stress on the quality and quantity yield of Lilium LA cv.Termoli, a pot experiment was conducted based on completely randomized design in sand and perlite medium (50:50) in three levels of potassium (Kfree, 6 mM K and and 12 mM K in Hoagland solution) with three replications. In the present study, the...
