in drought stress condition, it is important to estimate the n and k requirement of sugar beet. a drought-tolerant sugar beet genotype, bp karaj, was evaluated in split plot factorial design based on a randomized complete block design with four replications at motahari research station, karaj, iran for three years. main plots were allocated to irrigation treatments including normal irrigation (...
Basically, the most important limiting factor in plant growth is the lack of water. More lands in Iran are located in arid and semi-arid region and so identifying of ghenotype that can produce acceptable yield under drought conditions is essential. In order to identification of drought stress tolerant varieties, 20 wheat cultivars were evaluated at three stress levels (control, -0.6 and -1.2 MP...
محدودیت منابع آب و خشکسالیهای اخیر، لزوم استفاده از سیستمهای نوین کشت محصولات را برای کاهش آب مصرفی و افزایش بهرهوری آب ایجاد کرده است. این پژوهش در سال 1395 در مجتمع گلخانهای دانشکده کشاورزی دانشگاه شهید چمران اهواز اجرا گردید. در این پژوهش اثر روشهای کم آبیاری تنظیمشده (RDI) و خشکی موضعی ریشه (PRD) بر گوجهفرنگی در شرایط کشت هیدروپونیک بررسی گردید. این آزمایش در قالب طرح کاملاً تصادفی ...

the pollution of soil by heavy metals is considered to be quite a big problem in many areas ofthe world. to limit the accumulation of lead and cadmium from soil in the products, a correct understanding ofthe characteristics and specifications of the translocation of cadmium and lead is necessary. in order to evaluatethe effects of cadmium and lead interaction on zinc and manganese concentration...
in this study, a single layer sliced potato was dried using an infrared lamp heating under vacuum over three levels of radiant power including 100, 150 and 200 w, three slices thickness 1, 2 and 3 mm and the absolute pressure of 20, 80, 140 and 760 mmhg. samples were dried in triplicate to achieve 6% moisture content (wet based) which is suitable for long-term storage. drying rate was monitored...
