in order to study of yield and qualitative characteristics of potato (aola variety), an experiment was conducted in mashhad conditions under irrigation regims and different levels of potassium fertilizer. this experiment was based on randomized copmpletely block with split plot design with three replications in khorasan razavi agricultural and natural resource research center in 2010. three lev...

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...

We evaluated the effect of a low potassium diet on blood pressure in normotensive (NT) and in borderline hypertensive subjects (BHT). There were 11 BHT men (age, 24.6 +/- 1.2 years) and 10 NT men (age, 23.5 +/- 1.0 years). Subjects were studied while on both low potassium, high sodium (30 meq/day, 400 meq/day) diets and high potassium, high sodium (100 meq/day, 400 meq/day) diets, each taken fo...

Potassium in plants accounts for up to 10% dry weight, and participates in different physiological processes. Under drought stress, plant requires more potassium but potassium availability in soil solutes is lowered by decreased soil water content. Forming symbiosis with arbuscular mycorrhizal (AM) fungi not only enlarges exploration range of plant for mineral nutrients and water in soil, but a...

To determine the effects of potassium supplementation on endothelial function, cardiovascular risk factors, and bone turnover and to compare potassium chloride with potassium bicarbonate, we carried out a 12-week randomized, double-blind, placebo-controlled crossover trial in 42 individuals with untreated mildly raised blood pressure. Urinary potassium was 77+/-16, 122+/-25, and 125+/-27 mmol/2...

     For investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the Research Field of Islamic Azad University, Jiroft, Iran in 2013-2014. The main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of ...
