in order to evaluate salinity tolerance in 20 sugar bee genotypes, an experiment was conducted in two fields with salinity (ec= 12 ds/m, ph= 7.6) and non-salinity stress, in the form of rcbd at miandoab agricultural research station. different morphological and physiological traits such as root yield, sugar percentage, white sugar percentage, molasses, n, na, k, syrup purity and green cover per...

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...

for optimum utilization of saline soil and water resources, various methods have been proposed. application of best management practices and selection of salt tolerant cultivars are two important issues. selection and breeding for salt tolerant cultivars require potential genetic materials, screening and evaluation of them in laboratory and field experiments. starting in 2000, 80 sugar beet gen...

as water is the most restrictive factor in national agricultural production, it is necessary to take decreased water consumption and increased water us efficiency in crop production into consideration. nowadays, spring sugar beet production areas are concentrated in the region with water limitation and hence, the increase in spring production area contradicts the principle of water and soil con...

In a four-year experiment, five nitrogen rates (0, 60, 120, 180 and 240 kg N ha-1) were tested over irrigated sugar beets grown on clays, underMediterranean conditions, in centralGreece. There, sugar beets are commonly grown under water shortages, high temperatures and high soil Na concentrations. Contrary to previous reports, N rates did not affect significantly population density (as asse...

In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...

powdery mildew of sugar beet is a common disease in many sugar beet growing areas causing root yield and sugar content reduction. the aim of this study was to evaluate the effects of different irrigation methods on powdery mildew severity in sugar beet. eight susceptible and resistant commercial cultivars were evaluated under sprinkler and furrow irrigation systems in a randomized complete bloc...

resistance of 16 sugar beet cultivars to cercospora leaf spot was evaluated in ghaemshahr region. the experiment was conducted in a complete block design with six replications and disease severity of cultivars was measured two times. as a winter crop the root yield of cultivars and their disease severity compared under natural cercospora infection in dezfoul area in a complete block design with...

objective: a field experiment was conducted at dorud region, iran, during 2013. the aim of this research  was study on effect of different biofertilizers and irrigation closed time on some agronomic characteristics of sugar beet (beta vulgaris l.). methods: the experimental design was factorial based on rcbd with three replications. treatments were three irrigation closed time [oct-6 (a1), oct-...
