rhizomania disease is one of the most important threats to worldwide and iran sugar beet cultivation. many studies have been done to understanding the physiological effects of the disease on sugar beet, but in iran conditions has not been done any study for this purpose. this experiment was conducted with four sugar beet cultivars named as brigita, zarghan, jolge and rasoul in 2010 and natural ...

golmehr cultivar originated by crossing between i.l.111 line and zarghan 279 cultivar in karaj. the new cultivar and 19 safflower lines and cultivars were studied for grain yield and its stability, at karaj, isfahan, darab and zabol regions in 2006 -2009. the experimental design was randomized complete block with four replications. based on the results, golmehr cultivar with the highest grain y...

during 2000-2001, soil pythium species were studied in fars province. soil samples werecollected from various parts of the province (abadeh, bajgah, bayza, borazjan, darab, estahban, fasa,khafr, sepidan, shiraz, moharloo, and zarghan). isolates were recovered from soil by baiting. specieswere identified based on morphological characters of sexual and asexual organs, growth rate at differenttemp...

In this paper the geometrical relationship of the folds which exist in the Folded Zagros Mountains, including Asef Mountain (northern Iran), were studied. The southern and western zones of the Zagros Mountains are called the Folded Zagros. These zones extend approximately 1,375 km in length with a width ranging from 120 to 250 km. Asef Mountain is located in northern Shiraz (from northern Sarda...

in order to evaluate efficiency of nitrogen fertilizers consumption in a sugar beet monogerm hybrid variety of zarghan, a field experiment was conducted in a loamy soil during 2007 in the research farm of sugar beet seed institute located in karaj. five levels of nitrogen fertilizers including 0 (check), 120, 160, 200 and 240 kg/ha of net nitrogen from urea fertilizer (46 percent of pure nitrog...

in order to further understand the emergence and germination of sugar beet monogerm cultivars under moisture stress, the current study was carried out at three stages. at the first stage, the quality of germination of three monogerm cultivars (rizofort, rasoul and zarghan) were studied under five moisture stress levels (0, -2, -4, -6 and -8 bars) in germinator at 15°c by between-paper method. a...

in order to evaluate the effect of freezing stress on safflower (carthamus tinctorius l.) genotypes, an experiment was conducted in faculty of agriculture, ferdowsi university of mashhad, iran. treatments included 6 genotypes (k.w.3, k.w.6, k.w.16, zarghan 279, line 295 and il-111) and freezing temperatures (0, -4, -8, -12, -16 and -20 ˚c). the trial was arranged as factorial based on completel...

damage caused by water shortages leads to physiological and biochemical changes in metabolism of plants and make them predispose to attack by pests and diseases and reduce the quality of the crops. in order to evaluate the effect of supplemental irrigation on safflower fly (a. helianthi) population of safflower cultivars, an experiment conducted as a split plot based on randomized complete bloc...

this study was conducted to determine the appropriate irrigation interval on the basis of cumulative water evaporation from standard evaporation pan (class a) and to find out the effects of irrigation regimes on growth indices and on qualitative and quantitative yields of sugar beet. the experiment was conducted in 2005 at the lavark agricultural experiment station fields, isfahan university of...
