citric acid has been reported to increase utilization efficiency of dietary phytate-bound phosphorus and protein. objective of this study was to determine the effects of citric acid on growth performance and nutrient retention of broiler chickens fed diets having two levels of non-phytate phosphorus and rice bran. giving a completely randomize design in 2 × 2 × 2 factorial arrangement, 144 broi...

to survey the effects of chemical and biological phosphorus on the yield and essential oil of satureja hortensis l. as an important medicinal plant, factorial experiment was conducted based on randomized complete block design with three replicates at research station of faculty of agriculture, urmia university in 2011. the treatments were chemical phosphorus fertilizer with four levels (0, 50, ...

Background/Objective: Hyperphosphatemia is the consequence of end stage renal failure. Inadequate control of serum phosphorus results in elevated Ca×P product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification.  In this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis patie...

introduction: soil fertility management is a key factor in achieving sustainable agriculture. use of organic fertilizers is one of the methods that without environmental harmful effects with improvement of chemical and biological conditions increases soil fertility. nitroxin contains a collection of the best strains of nitrogen fixation bacteria of the genus azospirillum and azotobacter. these ...

this study was carried out to determine effects of phosphorus residual applied to wheat on vetch (vicia panonioca) growth, yields and some  soil  physical, chemical  properties in soil. the experiment was conducted with randomized completely block design in a field with three replications including four levels of p residual (applied for wheat p0, p15, p30, and p45 kg p2o5 in hectare) from tripl...

to evaluate the effects of some phosphorus solubilizing bacteria strains on yield and agronomic traits in local bean (phaseolus vulgaris l.) of guilan, different phosphate fertilizer rates were tested during 2014 growing season. this research was carried out in experimental field of agricultural and natural resource research center of guilan province as split plot arrangement based on randomize...

conclusions while high serum pth, calcium, and phosphorus levels could determine the mortality risk in hemodialysis patients, decreased serum phosphorus and pth levels were in association with malnutrition and comorbidities and were not independent risk factors for mortality. background abnormal mineral metabolism is common among hemodialysis patients and has been associated with higher morbidi...

BACKGROUND: Soil nutrition management is an important factor, which determines the plant growth. Soil fertility is determined by the presence or absence of nutrients i.e. macro and micronutrients, which are required in optimum level for crop. OBJECTIVES: Evaluate the effect different amount of nitrogen and phosphorus fertilizers in maize field under sugarcane ...

in order to investigate the effect of consumption of nitrogen and phosphorus fertilizers on harvest indices and some important agronomic traits of triticale (triticosecale wittmack var. javaniloo), a factorial experiment based on the randomized complete block design with three replications was conducted in paddy field of rice research institute of iran (rasht) during 2010-2012 for two years. th...
