research on crop response to deficit irrigation is important to reduce agriculture water use in areas where water is limited resource. using drought resistant landraces with irrigation scheduling based on phenological stages in semi-arid and arid regions may provide an opportunity to optimize irrigation efficiency and water savings in these regions. in order to evaluate of yield and yield compo...
بررسی عملکرد،اجزای عملکرد و شاخص های تحمل به تنش در ژنوتیپ های مختلف ارزن تحت رژیم های متفاوت آبیاری
با توجه به اینکه کمبود آب یکی از مهم ترین عوامل محدود کننده تولید محصولات زراعی در مناطق خشک و نیمه خشک می باشد لزوم شناسایی ارقام مقاوم به خشکی و همچنین معیارهای مناسب برای انتخاب این گونه ارقام ضروری است. لذا به منظور بررسی عملکرد، اجزاء عملکرد ژنوتیپ های مختلف ارزن و تعیین متحمل ترین ژنوتیپ براساس شاخص های تحمل به خشکی تحت رژیم های مختلف آبیاری آزمایشی به صورت کرت های خرد شده در قالب طرح بلو...
in a sustainable agriculture system, application of the fertilizers which are nature friendly and suitable for plants is essential. this becomes more important when dealing with medicinal plants. therefore, a factorial experiment in a randomized complete block design with three replications was set up in the 2012-2013 on nigella sativa l. treatments were nanofertilizer (pharmks®) (at 2 levels ...
1.1 introduction “i see translation as the attempt to produce a text so transparent that it does not seem to be translated. a good translation is like a pane of glass. you only notice that it’s there when there are little imperfections- scratches, bubbles. ideally, there shouldn’t be any. it should never call attention to itself.” “norman shapiro” (venuti, 1995:1) edward fitzgerald is the br...
to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...
Extended Abstract Introduction and Objective: Drought stress is one of the most important factors in reducing yield and barley production in rainfed arid regions, and counteracting or reducing the effect of stresses as a useful solution to increase barley yield. Therefore, improvement of stress-tolerant and suitable barley cultivars for arid and semi-arid regions is essential. Material and Me...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
a experiment was lay out in order to evaluate the effects of different biofertilizers on yield and yield components of maize at the lorestan provience, iran. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitrokara (n1), o4 (n2), o6 (n3) and control (n4)) and three phosphate biofrtilizers (phosphate barvar2 (p1), biozarr (p2), mc1+p...
Grass pea (Lathyrus sativus L.) is a crop which could substitute soybean in poultry ration in arid and semi-arid regions. To investigate the effects of sowing date and plant density on yield and yield components of grass pea, a factorial experiment based on randomized complete blocks design with four replications was conducted at Research Farm of Faculty of Agriculture, University of Birjand in...
