genus polymyxa, belongs to plasmodiophoromycota phyllum and protozoa kingdom. this fungus is a obligate endoparasite in the root cells of vascular plants. since the two species of this genus, p. graminis and p. betae are both known to carry destructive viral agents to sugar beet and poaceae. for studying the distribution of infected fields with p. betae in razavi and northern khorasan provinces...

Sugar beet pulp is a by-product from the processing of sugar beets into sugar. Beet pulp is extracted grounded sugar beet. It is used as livestock feed and it can be fed fresh, dried and ensiled (fermented beet pulp). Sugar beet pulp is a by-product from the processing of sugar beet which is used as fodder for cattle and other livestock. It is supplied either as dried flakes or as compressed pe...

in this study, total factor productivity(tfp) growth of sugar beet in iran during 1989-1990 through 2007-2008 was analyzed, using nonparametric malmquist approach. so, amounts of inputs usage including seeds, fertilizers, insecticides, herbicides, labor, water use and acreage in one hand and output of sugar beet production on the hand were taken into account. results showed that sugar beet prod...

Sugar beet production remains unprotected after the ban on neonicotinoids, while pest pressure is increasing. Although organic approach to agriculture highly welcomed, question whether it will be possible grow sugar without pesticides. The aim of this study determine efficacy seed treatments with neonicotinoids main pests, susceptibility pests under specific climatic conditions and discuss cons...

The systemic insecticide imidacloprid may be applied to deciduous trees for control of the Asian longhorned beetle, an invasive wood-boring insect. Senescent leaves falling from systemically treated trees contain imidacloprid concentrations that could pose a risk to natural decomposer organisms. We examined the effects of foliar imidacloprid concentrations on decomposer organisms by adding leav...

Exogenously supplied indole-3-acetic acid (IAA) stimulated ethylene production in tobacco (Nicotiana glauca) leaf discs but not in those of sugar beet (Beta vulgaris L.). The stimulatory effect of IAA in tobacco was relatively small during the first 24 hours of incubation but became greater during the next 24 hours. It was found that leaf discs of these two species metabolized [1-(14)C]IAA quit...

Sugar beet (Beta vulgaris L. cv. Monogerm C.S.F. 1971) seeds sown into Vineland fine sandy loam, infested with 15,500 H. schachtii juveniles/pot, showed little growth during an 11-week test in the greenhouse. Seedlings transplanted at 2, 4, and 6 weeks of age had 32, 30, and 31% less top weight and 71, 68, and 59% less root weight, respectively, compared to controls grown in nematode-free soil....

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...

The endophytic bacterium Pseudomonas poae RE*1-1-14 shows broad antagonistic activity and is applied to seeds as a biocontrol agent to suppress late root rot in the sugar beet. The completely sequenced 5.5-Mb genome reveals genes that putatively contribute to this antagonistic activity and the intimate plant-microbe interaction.

Sugar and fodder beet were grown in three years to assess the potential sugar yield for ethanol production in the region. Fresh weight root yields ranged from 70-85 t/ha for sugar beet and 55-136 t/ha for fodder beet. Sugar contents averaged 15% for sugar beet and 10117o for fodder beet resulting in sugar yields of 10-12 t/ha and 5-12 t/ha respectively. Consistently higher sugar yield from suga...
