this experiment was conducted in order to study the influence of different levels of municipal solid waste compost and nitrogen rate on grain quality of sweet corn (zea mays l. saccharata) and some soil properties under marvdasht conditions during growing season of 2008-2009. the experiment was arranged as split plots based on a randomized complete block design with two factors and three replic...

Tea has several types of essential elements. Potassium, magnesium and phosphorus are some examples of these elements. Tea is widely used drink in Turkey, also some people puts a lemon wedge to tea for different taste. In this study potassium, magnesium and phosphorus contents after the hot water brewing of black and green tea were determined by Optical Emission Spectroscopy (ICPOES). Furthermor...

This study was conducted in order to investigate the effect of drought stress and Azomite fertilizer on some physiological traits of two tomato (Lycopersicon esculentum M.) cultivars (izmir and Izabella). A randomized complete design with factorial arrangement with three replications was used. Treatments consisted of three levels of irrigation including FC (control), FC (mild drought stress), a...

While studying the factors affecting the absorption of mineral elements by plants, the writer showed that the hydrogen-ion concentration of the medium affects the absorption of potassium and phosphorus by wheat seedlings grown in water cultures. (4) ^ More phosphorus was absorbed from potassium phosphate solutions with initial pH values of 5.0 and below than from those with pH values of 6.0 and...

New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...

an experiment was conducted as randomized complete block design with three replications and 14 fertilizer treatments in year 2014. the treatments were including the control, application of chemical fertilizers according the soil analysis, application of 15, 30 and 45 tons of municipal  waste compost per ha as simple and with 25, 50 and 75% of chemical fertilizers. the results revealed that the ...

The utilization of rocks as fertilizers is limited by their low solubility. However, solubilization may be achieved by some micro-organisms, such as ectomycorrhizal fungi (ECMf). The aim of this study was to evaluate the potential of seven isolates of ECMf to solubilize two rocks, alkaline breccia and granite, and to liberate potassium and phosphorus for Eucalyptus dunnii seedlings under greenh...

in this study for determinination of effects of anesthesia with propofol on some of biochemical factors of blood, 120 grass carp were chosen. the fish were exposed to the ascending concentration of propofol by bath method and injection method. at the time of anesthesia and 4 days after anesthesia blood samples were taken from the caudal vein and some biochemical parameters of blood were measure...
