Climate change and the global warming phenomenon is one of the main concerns of human societies. In this study, the impact of climate change on rice, as the main crop in Guilan province, Iran and soybean production as the second crop was investigated. To adapt to the negative impact of climate change in future, optimal crop calendars were indentified for different rice and soybean cultivars usi...

abstract the aim of this study was threefold: (1) to investigate the relationship between knowledge of semantic prosody and efl learners general language proficiency; (2) to examine the relationship between qualitative as well as quantitative knowledge of words, and (3) to compare the performance of efl learner on receptive and productive measures of semantic prosody. the study is based on a...

To evaluate the effect of weed interference, sowing date and method on phenology, growth, protein and yield of red bean, a split-split plot experiment based on a randomized complete block design with three replications was conducted in the Research Field of College of Agriculture, Shiraz University, Shiraz, Iran during 2013- 2014 growing season. Main plots consisted of planting methods (single-...

in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...

In order to investigate the effect of agrophysiologic traits of bread wheat cultivars to planting date, the present research was conducted on the basis of split plots experiment based on randomized complete blocks design with three replication during 2012-2013 at the research farm of Khuzestan Agriculture and Natural Resources Research Station. Three planting date mid-October, mid-November and ...

Unsuitable planting and weed competition are the most important factors that greatly reduce the yield of bean. In order to study the effect of planting date on yield and yield components of three white bean cultivars in weed infest and weed free condition a factorial experiment with randomized complete block design and three replications was carried out at Semirom in 2009. The treatments were p...

efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...

To determine the proper nitrogen fertilizer rates and its application times for achieving high grain and oil yields of rapeseed cultivar, Hyola 401, a research was carried out in paddy fields of Rice Research Institute of Iran in Rasht during two cropping seasons. A factorial experiment was conducted in a completely randomized block design with three replications. The experimental factors w...
