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...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
in order to evaluate some agronomical management on weed control in sugar beet this experiment was conducted at safi-abad agr.res.center, dezful in 2002 and 2004. tow planting dates, september 16 and october 12 and five cultivator applications, one and two time application at 4-6 and 6-8 leaf stages, respectively and once plus hand hoeing, weedy and weed free checks arranged in split plot desig...
abstract mango is one of the most important tropical fruits in iran and salinity is an important problem to mango production in ‘hormozgan’ province and other mango growing areas in iran. at present experiment the effects of saline irrigation water of different sodium chloride concentration on vegetative growth and ion content of mango was evaluated. treatments comprised two type of cultivars (...
to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...
one of the most effective ways to deal with drought stress and increase water use efficiency is the development of drought-tolerant varieties which display less reduction in yield per unit water reduction. therefore, the breeding of diploid pollinators was considered as an essential measure for producing drought-tolerant hybrids. in this study, from 4 diploid pollinator populations, 45 half-sib...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
Defoliation produced by abiotic factors and the subsequent re-growth can reduce sugar beet (Beta vulgaris L.) sucrose content and final sugar yield. Field experiments were conducted during 2003 and 2004 growing seasons in the farm of Hellenic Sugar Industry SA, Larissa factory, central Greece. Three sugar beet cultivars (Rival, Europa and Corsica) were ordinary irrigated till the beginning of J...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
For ranking and grouping of full-sibs and hybrids of sugar beet obtained from breeding programs, two separate experiments were carried out at the farm of the Agricultural and Natural Resources Research Station of Miandoab in 2017 under saline and normal conditions. For this purpose, 17 full-sibs and 28 hybrids differing in resistance and susceptibility to environmental stresses were investigate...
