iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
this study was conducted to determine the effects of different water and nitrogen application levels on drip-irrigated tomato plants. the amount of water usage was based upon the pan evaporation from a screened (class “a”) evaporation pan. the treatments consisted of two irrigation intervals (i1= 5 days and i2= 10 days), three plant-pan coefficients (kcp1= 0.50; kcp2= 0.75 and kcp3= 1.00) and t...
Extraordinary importance of Date-Palm, Phoenix dactylifera especially ‘Piarom’ variety and also undeniable effect of nitrogen and phosphorus on yield and quality of this product, caused this research to be accomplished. The research was performed during two years on 72 (4*3*3*2=72 trees) fruitful, 12 years old trees in Hormozgan province. Treatments were consisted of four levels of nitrogen (0,...
In order to investigate the effects of different nitrogen fertilizer levels and water stress during milky and dough stages on grain yield, yield components and water use efficiency of corn hybrid SC 704 (late maturing, non prolific and dent type), a field study was conducted. The factorial design of the study comprised of a randomized complete block with four replications. Four levels of nitro...
in order to study the effects of terminal heat stress and nitrogen on morphophysiological characteristics, anue (agronomical nitrogen use efficiency) and yield of canola, an experiment was conducted at research farm of ramin agricultural sciences and natural resources university. the experiment was arranged in split plots based on randomized complete block design with four replications. main pl...
in order to study the effects of different levels of drought stress and plant growth promoting rhizobacteria on the germination indices of seeds harvested from wheat (tritium aestivum l.) cv. sayonz in the field treated with different levels of nitrogen, in controlled conditions, a factorial layout based on completely randomized design with three replications, was conducted. treatments included...
n order to investigate the effect of nitrogen fertilizer rates and top dressed on nitrogen remobilization in different rice cultivars, a field experiment was conducted in the rice research institute of iran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 factors were used in which fertilizer rates in 3 levels (including 46,...

In order to assess the effect of nitrogen application and planting methods on linseed and berseem clover yield and yield components in an intercropping system an experiment was conducted as a split plot based on randomized complete block design with three replications at the Research Farm of College of Agriculture, Isfahan University of Technology, Isfahan, Iran in 2013. Experimental factors in...
in order to investigate the effect of consumption of nitrogen and phosphorus fertilizers on harvest indices and some important agronomic traits of triticale (triticosecale wittmack var. javaniloo), a factorial experiment based on the randomized complete block design with three replications was conducted in paddy field of rice research institute of iran (rasht) during 2010-2012 for two years. th...
