the aim of this research was to evaluate the average concentrations of micronutrients including: copper (cu), iron (fe), manganese (mn) and zinc (zn) in the shoots of different cultivars of wheat in stem elongation stage in a soil contaminated with cadmium (cd). the treatments consisted of three levels of cd (0 (as control, cd0), 40 (cd40) and 80 (cd80) mg cd/kg soil) and fourteen different cul...
the aim of the current study was to investigate the relationship among efl learners learning style preferences, use of language learning strategies, and autonomy. a total of 148 male and female learners, between the ages of 18 and 30, majoring in english literature and english translation at islamic azad university, central tehran were randomly selected. a package of three questionnaires was ad...
Iron (Fe) and zinc (Zn) deficiency is common in wheat growing areas of the world particularly in calcareous soils. Soil application of chemical fertilizers is considered as a cost-effective and easy approach to combat micronutrient deficiency. However, due to economic, environmental, and agronomic constrains, efficiency of soil fertilization is low in most calcareous soils. Therefore, finding p...
abstract the current study set out to address the issue as to whether the implementation of portfolio assessment would give rise to iranian pre-intermediate efl learner autonomy. participants comprised 60 female in pre-intermediate level within the age range of 16-28.they were selected from among 90 language learners based on their scores on language proficiency test -key english test. then, t...
abstractin order to investigate the effects of the inoculation with p. putida, r. leguminosarum bv. phaseoli and f. mosseae on yield and nutrient uptake of common bean (phaseolus vulgaris l.), a greenhouse experiment in a completely randomized factorial design with 3 treatment including a: microorganism in four level (no inoculation, p. putida, f. mosseae and mix inoculation of fungi and bacter...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
The present study was based on the hypothesis that Boron (B) induces changes of other micronutrients in soil-plant systems. A preliminary study was carried out in sand culture growing radish (cv. French breakfast) as a test crop, under green house conditions. The experiment was laid out in a randomized complete block design and replicated three times. Boron was applied at the rate of 0, 0.25, 0...
in order to investigate the effect of cd and zn on uptake, concentration and the translocation factor of the cd and zn in the rice plant, a factorial experiment was conducted with four factors including two rice cultivars of vandana and hashemi, two waterlogged and non-waterlogged conditions and three levels of zn and cd (0, 5 and 10 mg kg-1 soil). the experiment was carried out in a randomized...
ABSTRACT-Water stress is the main cause for crop yield reduction in the majority of agricultural regions of the world because it affects almost all plant functions. The effects of Glomus mosseae on growth, nutrients uptake, and antioxidant enzymes of sour orange (Citrus aurantium) and rough lemon) Citrus jambheri) rootstocks were assessed in sterilized soil under greenhouse conditions. A three...
