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...
this research was carried out to investigate the effect of different levels of potassium (in nutrient solution), harvest season and plant density on yield and quality of strawberry cv. selvain hydroponic system conditions. the tests were done in the greenhouse, and laboratories of horticultural science department of the university colleg of agriculture and natural resources of tehran university...
Removal of potassium from Hydra culture medium produces a decrease in intracellular potassium and a parallel decrease in asexual growth rate. Rubidium and caesium are ineffective as substitutes for potassium in the maintenance of growth rate. Increases in intracellular potassium parallel increases in growth rate up to a level somewhat below the normal steady-state level of intracellular potassi...
BACKGROUND Although a decrease in serum potassium level has been suggested to be a fairly common observation in acute coronary syndrome (ACS), there have so far been no definitive reports directly demonstrating the transient potassium decrease (the potassium dip) during ischemic attack of ACS compared to stable phase in individual patients. To understand the pathophysiological significance of t...
BACKGROUND & AIMS Evidence has suggested that low serum potassium concentration or low dietary potassium intake can result in many metabolic disorders. Our objective was to evaluate the association between serum potassium level and risk of prevalent metabolic syndrome. METHODS We conducted a cross-sectional study in 10,341 participants aged 40 years or older. Metabolic syndrome was defined ac...
Potassium is one of nutritional element that has an important effect on the quantity and quality of rice plant. Knowledge about the K critical level and plant response to different application rate of K, can effectively help with the proper use of this element. Therefore, in this study potassium (K) critical level for rice (Khazar variety) and prediction equation for grain yield were determined...
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 crop ...
