Abstract Selenium is an important element for human and animal nutrition and deficiencyproblems of it in our soils is likely The deficiency and toxicity range of selenium is verynarrow and can cause nutritional problems for human and animal health Plants canaccumulate various amounts of Se in their tissues The objective of this study was toexamine selenium and cow manure treatments effects on crop yield and seleniumconcentration and uptake of plants The study was carried out in a greenhouse using afactorial experiment design in a completely randomized plot with three replications Thetreatments were five levels of 0 5 10 20 and 40 g ha 1 of selenium and 0 and 100 Mg ha 1of cow manure The soil used was from Lavark experimental station and test plants wereAlfalfa Medicago sativa and Fescue Festuca arundinacea The plants were harvested inthree cuts each cut when the height reached 20 cm The harvested samples were ovendried weighed and selenium concentrations were measured in them Crop yields and plantgrowth were affected by the cow manure treatments in all the cuts but seleniumconcentration of the plant tissues and selenium uptake of plants diminished Alfalfa had thehighest yield in all the treatments Selenium treatments had no effects on the crop yieldsand plant growth Selenium concentration and plant uptake increased with increasingselenium treatments in all of the cuts The results of this study showed that in absence oforganic matter content selenium fertilizer could effectively increase the seleniumconcentration and plant uptake of selenium
