  To study the effect of harvesting time on the quantity and quality of sugar beet, 3 harvest dates (October 22nd, November 6th& November 21st) and on the five varieties of sugar beet (Afshari, Zarghan, Shirin, Rasul& jolgheh) were evaluated. The study was conducted in factorial experiment based on complete block design with three replications in Khoy Agricultural Research Center during 2009. Cultivation operations in mid-April, based on recommendations and the same for all treatments were performed. Analysis of variance showed significant differences between cultivars in terms of sugar content, white sugar content, alkality, sodium and nitrogen impurities. Variety of Rasul sugar content and white sugar content was more than other varieties. The difference between harvesting dates of the root yield, sugar content, white sugar content, white sugar yield and sugar yield was significant. November 21st harvest root yield found with 94.360 tons per hectare more than previous harvest dates. The highest sugar content, white sugar content was related to the date of November 21st and was higher than other harvest dates. The highest sugar yield and white sugar yield respectively, 12.98 and 10.34 tons per hectare belonged to November 30th harvest. That was of significant difference rather than two other dates.

  Micronutrients have an important role in growth and yield of plants. This investigatin was carried out to evaluate effect of foliar applications of three micronutrients (Fe, Mn and Zn) at different times (4-6 and 8-10 leaf stage) with three replication on sugar beet. Based on results obtained all of the micronutrients used increased sugar beet sugar yield. Highest root yield was obtained by using 9 % of micronutrients at 4-6 leaf stage, but other concentrations did not have any effect on sugar beet yield. All of the three micronutrient concentrations increased root yield significantly. Application of 6% concentration increased root yield by 15.6 %. Mn application did not have any effect on sugar yield. 9 % concentration of Zn foliar application increased sugar yield by 16.4 %, and application of 6 and 9% of Fe increased sugar yield by 18.6 and 36 % respectively. Sugar percent did not changed by Mn application, but high concentrations of Fe and Zn at 8-10 leaf stage increased it. Highest increase in sugar percent obtained by using Fe 9 % foliar appliction. Because of economical importance of sugar and root yield, foliar application of 9 % of Fe and Zn at 8-10 leaf stage will be suitable. Manuscript profile

  The effect of times of weeding on reducing herbicide dose in sugar beet was studied in 2011-2012 in Jovein. The experiment was conducted in split plot based on a randomized complete block design with three replications. The main factor was herbicide doses (0, 25, 50, 75 and 100% of recommended dose (Chloridazon 3.25 kg. a.i. ha-1 soil applied) and sub plot was times of hand weeding (0, one time hand hoeing, tow times hand hoeing, at 30 and 60 days after plant emergence). Traits like root yield and white sugar yields, impure sugar content, alkalinity coefficient, sodium, potassium, α-amino nitrogen and sugar content in molasses were evaluated. The result showed that the increased frequency of weeding reduced weed density, weed dry weight, α-amino nitrogen and percentage of impure and pure sugar contents, root yield and sugar yield. The least weed density and biomass of weeds were observed in recommended dose. Increasing the doses of herbicide increased impure sugar content (14.48%), α-amino nitrogen (57.86%), pure sugar (19.30%), root yield (77.67%) and sugar yield (111.17%) while it decreased potassium (18.77%), sodium (28.84%) contents and alkalinity coefficient (52.76%) as compared with that of control. For most of the traits, there were not statistically significant difference between the recommended dose and 75% of the recommended dose. Increasing the number of hand weedings reduced herbicide dosages. The, results finally showed that 25% dose reduction of herbicide in one time weeding and 50% dose reduction of it in twice weedings might produce desirable economic yield (root yield).

  In the study, to survey the growth, yield, and physiological responses of valerian (Valeriana officinalis L.) using different concentrations of urea fertilizer (0, 30, 60, 90, and 150 kg.ha-1) and nitroxin and phosphate Barvar-2 bio-fertilizers, an experiment was conducted in medicinal Plants farm, Tehran, as a factorial in a randomized complete block design with three replications in the 2019-2020 crop year. Seedling cultivation was carried out in mid-May and urea fertilizer treatment was performed in two stages. To measure root and biological yield, one square meter was harvested from each plot and the dry weight of shoot and root was measured and the sum of these two was calculated as biological yield. Root and rhizome essential oils were extracted by water distillation (Clevenger) and valerenic acid by high performance liquid chromatography (HPLC). Essential oil yield was also calculated based on the essential oil percentage and dry root yield. The average root diameter varied from 7.97 (90 kg urea per ha) to 5.14 mm (control). The highest root yield was obtained in 150 and 90 kg urea.ha-1 along with inoculation with nitroxin and phosphate Barvar-2 (4.88 and 5.1 ton.ha-1, respectively). Application of 90 kg urea.ha-1 along with nitroxin resulted in increased chlorophyll b and total content. Increasing the urea concentration decreased essential oil content and increased essential oil yield. Essential oil content ranged from 0.93 (90 kg urea.ha-1 with nitroxin and phosphate Barvar-2) to 1.94% (no-application of fertilizers). The highest valerenic acid content (0.46% of the extract) and valerenic acid yield (220.27 mg.ha-1) were observed using 30 kg of urea with phosphate Barvar-2 and no application of nitroxin. In general, application of nitroxin and phosphate Barvar-2 bio-fertilizers along with 90 kg urea.ha-1 by improving growth, yield, and physiological traits led to the production of acceptable essential oil and valerenic acid yield.

  In order to evaluate of weeds control at different levels of sulfur coated urea on yield and qualitative characteristics of sugar beet, a study was carried out as split plot design in randomized complete blocks design with four repetitions in Shoushtar region during 2016. Experimental treatments consisted of four different levels of sulfur coated urea (SCU) (0, 150, 180 and 250 kg.ha-1). The use of herbal treatments of chloropyralide + Des Modifam + Moeifam + Autophamousite and metamitron + Modifem + Autophamousite as a sub-agent. The results showed that weed dry weight was affected by different amounts of urea with sulfur coating and increased with increasing sulfur content of urea, which increased the weed weight of weeds, so that it was highest in application of the highest amount of urea with sulfur content per hectare with no weeding of weeds. The amount of 237 grams per square meter was obtained. Also, in the effects of fertilizer interaction and weed control, the highest yield of sugar beet (13421 kg) was attributed to full weed treatment and the highest application rate of sulfuric urea. The highest root yield of sugar beet (57004 kg ha-1) was related to weed control and application of the highest amount of sulfur urea. Among the weed control treatments, the highest root yield of sugar beet (46711 kg.ha-1) was obtained in metamitron + Des medifam + Autophamousite herbicide application and application of the highest amount of urea with sulfur content per hectare. Also, the highest percentage of pure sugar in the treatment of non-application of sulfur content of urea with non-control of weeds was 18.6% and 20.30%, respectively. In general, it can be said that Urea fertilizer with sulfur coating with the use of Médifam + Des Moiifam + Autophamousite + Metamitron has the optimum performance of sugar beet.   Manuscript profile

  Development of autumn sowing of sugar beet is viewed as an important strategy for supplying required sugar nationwide. In order to investigate the effects of varieties and sowing date on qualitative and quantitative characteristics of sugar beet, an experiment was conducted in a form of split plot based on the Randomized Complete Block design in crop year 2014-15 in a research farm of Agricultural and Natural Resources Center in Khorasan Razavi province with four replications. The major factor included sowing data; the minor factor included. The studied characteristics contains number of roots, bolting percent, root yield, gross sugar yield, white sugar yield, sugar percent, alkalinity, sodium, potassium, and nitrogen. Analysis of variance indicated that interactive effect of variety and sowing date on bolting percent, root yield, gross sugar yield, root number, white sugar yield, and sugar was significant. The highest root yield in the first sowing date was related to Merak and Monatono; the lowest root yield was related to Sharif and Monatono in the second sowing date. Also, the highest gross sugar yield and white sugar was obtained for Merak in the first sowing date. In addition, it was found that the first sowing date was superior to the second. Due to the multiplicity and diversity of the autumn cultivars and their favorable adaptation to cultivation in different Beet cultivation regions of the country, it seems that the development of the autumn sowing beet, while supply the country sugar requirements, causes significant savings in water consumption.

  Bolting is always one of the limitations of sugar beet autumn cultivation. In this regard, a factorial experiment based on randomized complete block design with three replications was conducted on semi-resistant cultivar of Sharif at Moghan Research Station during two seasons of 2014-16. Experimental factor A (planting date) with three levels including a1 (10th October), a2 (25th October) and a3 (16 November) and second experiment factor (B) paclobutrazol foliar application with two levels b1 (300 mg / l) and b2 (no spraying). The results of combined analysis of variance showed that the effect of planting date was significant at 5% probability level for the white sugar content, root sodium, extraction coefficient sugar and molasses sugar, and also the interaction between planting date and paclobutrazol was significant for bolting at 5% probability level. Comparison of the mean data showed that the first sowing date showed the highest bolting and root yield with 20.88% and 51.52 ton / ha, respectively, and the second sowing date had 50.8 ton / ha root yield. Which was in the same statistical group as the first planting date. But the bolting on it was 5.29%. The interaction effect of second planting date and consumption of paclobutrazol with 57.44 ton / ha and 4.23% had the highest root yield and the lowest bolting, respectively.Keywords:" Paclobutrazol"," Sugar beet"," Autumn sown"," Bolting"," Root yield" Manuscript profile

     In order to evaluation the effects of different application methods of nitrogen fertilizer on sugar beet yield, an experiment was conducted in farms of agriculture faculty of Islamic Azad university, Tabriz  branch in 2005. A randomized complete block design based factorial with three replicates used for three cultivars (7233, PP22, and IC) and three nitrogen application methods (seedbed applying of nitrogen, spraying at 6-8 and 14-16 leaf stages). Results showed that applying methods and cultivars had not significant effect on root and sugar yield, but on sugar percentage. Nitrogen spraying onP22 increased root yield more than other cultivars. Among N applying methods, nitrogen spraying was more effective than others. Soil application of nitrogen increased sugar yield in 7233 and IC cultivars, whereas in PP22, the most effective method was nitrogen spraying in 14-16 leaf stage. Nitrogen spraying in PP22 for increasing root yield, and nitrogen spraying at 14-16 leaf stage in PP22, and seedbed applying of nitrogen fertilizer in 7233 and IC cultivars for increasing sugar yield was recommended.
