in order to evaluate the quantitative factors in fox tail millet (setaria italica l.) under three stages of growth, an experiment was conducted in birjand during spring and summer of 2010. the preliminary objective was evaluation of fox tail physiological characteristics on animals that feed them. planting of foxtail millet was performed according to local practices and endemic acknowledge. sam...
the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...
Background and Objective: Today, the presence and increase of particulate matter is one of the serious factors that threaten human health. In the meantime, trees can accumulate airborne particles by their foliage. In this study, the accumulating ability of various PM by the leaf of some tree and shrub species was evaluated in Isfahan. Materials and Methods: 12 species of trees and shrubs were ...
in order to study the source limitation and contribution of pre-anthesis assimilates to grain in dual-purpose (forage and grain) barley, a field experiment was carried out in iran, ahvaz region. the experimental design was split plot in randomized complete block with three replications. application rates of nitrogen at four levels (60, 120, 180 and 220 kg.ha-1 n) were as main plots, while sub p...
the so-called phytoextraction in which hyperaccumulator plants are used to remediate the contaminated soils is proven to be an efficient method. the objective of this study was to investigate the capability of spinach for phytoremediation of cadmium from cd-contaminated soils and determine the efficiency extent of spinach for phytoremediation. for this purpose, a randomized block experimental d...
growth analysis is a valuable method in the quantitative analysis of crop growth, development and crop production. there are many regression models to describe the sigmoid growth patterns. by considering that, the parameters of non-linear regression models have physiological meanings, they are preferable relation to linear regression models. the aim of this study was to collect and evaluate the...
in order to investigate the possibility of planting grass pea and common vetch crops after harvesting wheat and to evaluate the effects of green manure of these crops on yield of potato-wheat in croprotation cycle, this research was carried out using a randomized complete block design with four replications during 2006-2010 at khair-abad research station, zanjan, iran. the treatments were eith...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...
