the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
the present research was conducted under laboratory and field condition to determine seed priming effects on maize inbred line's germination, emergence, and grain yield. seeds of two maize inbred lines include of mo17 (as paternal line) and b73 (as maternal line with cytoplasmic sterility) in the laboratory conditions were subjected to hydropriming for 12, 24, 36 and 48 h, or osmoticprimin...
Crop depends on its canopy to intercept solar radiation to drive both assimilation and water, nutrient absorption for its growth. Field experiments, involving three sowing time and three sowing rate, were conducted at Luancheng Station to investigate the effects of canopy size and development on crop growth and radiation use efficiency (RUE) of winter wheat during 2009/2010 and 2010/2011 gr...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
augment of germination rate is important in seedling establishment and crop yield. a set of study in laboratory & field conditions at agronomy department of university of tehran was conducted during 2004-2005. in lab. experiment the effects of seed priming was evaluated on germination indices (germination percentage and rate) of chickpea genotypes in a factorial experiment of 4×3×2 arranged in ...
there are many methods for weed management one of them is putting allelopathic and cover crop in weed management programs. in order to study the effect of sowing time (delayed sowing, synchronic sowing) and wheat cultivars (shiraz, roshan, tabasi, niknejad) on allelopathic interaction of wheat and weed species (secale cereale l., avena ludoviciana l.: monocotyledon, convolvulus arvensis l. and ...

in the last decade, frequency of late cold incidence has increased in the upland forest nurseries. the aim of present study was to reduce the damage caused by spring frost and to increase the efficiency of persian maple seedlings production in mountain nurseries. this study was conducted as split plot design with two main treatments and three replications in two consecutive years (2009-2010) in...
abstract in order to study the effect of sowing date and seeding rate on essential oil content and composition of chamomile (matricaria recutita l.) cv. presov, prepared from slovakia, an experiment was conducted. the experimental design was split-plot in the basic of randomized complete blocked design (rcbd) with three replications. main plots consisted of three sowing dates (6 nov, 5 mar, and...
