considering the positive effects of silicon on salinity resistance by some agricultural plants, an investigation was conducted with a completely randomized design of three replications. the main objective was to determine the effect of silicon on nutrient content and nitrate accumulation in lettuce. electrical conductivity was adjusted at 3 mmhos/cm through addition of nacl. silicon was added t...

The measurement conditions for determining boron using graphite furnace-atomic absorption spectrometry (GF-AAS) were investigated. Differences in the boron absorbance profiles were found using three different commercially available GF-AAS instruments when the graphite atomizers in them were not tuned. The boron absorbances found with and without adjusting the graphite atomizers suggested that a...

introduction soil salinity is a major limiting factor in agricultural development within iran. nitrogen is the most important nutrient that its uptake is limited over other elements under saline conditions due to decrease in the permeability of plant roots, soil microbial activity and mineralization of organic compounds and nitrate uptake by high concentrations of chloride anions in the root zo...

Minimum inhibitory concentration of carbendazim among the 12 isolates Alternaria dauci (Kuhn) Groves & Skollo causing leaf blight carrot showed variation. Isolate Ad-11 was most sensitive have MIC 6% and Ad-2 highly resistant 20%. The effect Ammonium nitrate, Calcium Sodium nitrate Zinc were tested growth rate carrot. found to be best source nitrogen for both isolates.

this experiment was conducted to evaluate of different levels of water nitrate on performance and blood parameter of broiler chicks. 240 day old ross 308 were assigned in 5 treatments, 4 replicates and 12 chicks per replicate in a completely randomized design. treatments so that water nitrate concentration was 10 mg in drinking water of poultry farm (control group or cg) and another treatment 4...

parsley has a very high nutritional value, containing a, b and c vitamins and mineral nutrients. in order to investigation of the effect of different nitrogen sources on parsley an experiment conducted in a factorial combination of three nitrogen forms (calcium nitrate, ammonium sulphate and urea) and four nitrogen levels (0, 100, 125, 150 kg ha-1) by using a factorial experiment based on rando...

The aim of this in vitro study was to evaluate enamel microhardness following bleaching treatments using either high- or low-concentration hydrogen peroxide (HP) agents containing calcium and/or fluoride. Sixty enamel blocks were bleached with 1 of 6 different bleaching agents (n = 10). The high-concentration HP agents were Whiteness HP Maxx (35% HP), Whiteness HP Blue (35% HP, 2% calcium gluco...
