Sewage sludge at the rate of 0, 40, 80, 120 and 240 t/ha showed that the number of filled grains per panicle, dry weight of grains and weight of 1000 grains of rice (Oryza sativa L.) were the significantly highest where 240 tons of sewage sludge per hectare was added. The contents of N, P, K, Ca, Mg, Fe, Cu, Zn and Pb in rice grains increased significantly with increasing rate of sewage sludge ...

in order to evaluate the seed yield and qualitative traits and oil in some winter rapeseed (brassica napus l.) varieties as affected by micronutrient elements, this experiment was performed during 2011 - 2012 cropping seasons as split plot arrangement in randomized complete block design with three replications, in arak, iran. micronutrient fertilizers including of zero as check, fe, zn, mn, fe ...

This study assessed concentrations in and intake of toxic and essential elements from formulas and foods intended for infants during their first 6months of life. Concentrations of the essential elements Ca, Fe, Zn, Mn and Mo were significantly higher in most formulas than in breast milk. Daily intake of Mn from formula varies from ten up to several hundred times the intake of the breast fed inf...

abstract a hydroponics experiment was conducted to compare effect of fe-deficiency on concentration, uptake, translocation of fe, zn, mn in some plants. a completely randomized block design in triplicates was conducted in research greenhouse. seven plants with different fe-efficiency contained two bread wheat genotypes (triticum aestivium l. cvs. backcross roshan and qods), triticale (x. tritic...

Growth and spore formation of Candida albicans Y-45 was enhanced by low oxygen tension. Mycelium and chlamydospores were abundantly found on rice infusion-Tween 80 agar within 48 to 96 h, and abundant chlamdospore production occurred most rapidly under reduced oxygen tension and incubation at 30 degrees C. Zn, Mg, Mn, anf Fe were tested for their ability to promote filamentation in C. albicans ...

For aerobic life oxidative stress is an inevitable misfortune that is mediated by the high reactivity of active oxygen species. One of the detrimental species is the superoxide anion radical 0 2 . In biological systems this radical is disproportionated into molecular oxygen and hydrogen peroxide by the catalytic action of the enzyme SOD (superoxide:superoxide oxidoreductase; EC 1.15.1.1). SOD i...

background: iron, manganese, and aluminum are three abundant metals on earth and their concentrations have increased in aquatic environments as a result of natural and industrial activities. this study was undertaken to report the median acute toxicity (lc50) and accumulation of the sub-lethal concentration (10% 96-h lc50) of iron (fe), manganese (mn) and aluminum (al) in kutum (rutilus kutum) ...
