Determination of the most appropriate sugar beet planting date is one of the important factors influencing field management. The occurrence of frost damage after seedling emergence has been considered as a limiting factor for early sugar beet planting. This study was conducted to determine the proper sugar beet planting date in IslamabadGharb, Kangavar and Kermanshah (including Sahne, Bisotun and Mahidasht cities). A model was designed based on meteorological data collected from 1993 to 2008. After running a normality test for long-term soil and meteorological data (Shapiro-Wilk test) in each location, the probability of seedling damaging temperatures (less than -2 oC) during March to May was determined using normal distribution function. Then, according to the required base-temperature for germination and thermal units from planting to emergence as well as collected long-term temperature data at the depth of 5 cm in each region, the plausible planting and emergence time was predicted. Through combining the probability of less than 20% frost occurrence at -2 oC and proposed planting dates and prediction of field emergence, a plating-time model was developed for each region. Results showed that the average thermal units required from planting to seedling emergence was 173 growing degree days for all regions. Based on the results, the earliest planting date with less than 20% frost damage to sugar beet seedling for Kermanshah, Islamabad Gharb, and Kangavar were found to be 17th March, 22ndMarch, and 9th April, respectively.

In order to study the stability and adaptability of sugar beet genotypes under different climatic conditions, nine genotypes were evaluated in Isfahan, Karaj, Kermanshah, Khoy, Mashhad and Moghan regions in a randomized complete block design with four replications in 2015.Genotype × environment interaction was studied by estimating additive main effects and multiplicative interactions (AMMI) method. Analysis of additive main effects (analysis of variance) and multiplicative interactions (principal component analysis) showed significant effect of genotype (P < 0.05), environment (P < 0.01), and genotype × environment interaction (P < 0.01). Cumulative of first two principal components explained about 77% of the interaction variance. The biplot of the first interaction principal component and mean yield showed that JAAM had higher yield than the overall mean identified as a stable genotype. Based on AMMI2 graph, JAAM and (I13*A37.1)*SH-1-HSF.5 genotypes in Isfahan and Meshhad, 1571, (I13*KWS)*302-HSF.20, (I13*A37.1)*S1.88239, BR1 and ARAS 101 genotypes in Kermanshah and Moghan and IC and 7233 genotypes in Karaj had specific adaptability. Among all genotypes, 7233, (I13*A37.1)*S1.88239, JAAM and ARAS 101 had the highest general adaptability. Results showed the possibility of genotype selection for each location.

Sugar beet planting under autumn season has significant importance owing to higher water use efficiency especially in semiarid regions. In Kerman, sugar beet is only sown in spring, therefore it is important to evaluate the feasibility of autumn-sown sugar beet planting. Using geographic information system (GIS) combined with various factors influencing sugar beet growth is the best and economic method for identification of prone areas for autumn-sown sugar beet planting. The aim of this study was climatic zoning of Kerman region for autumn-sown sugar beet planting. Meteorological data including temperature and rainfall were collected. Then, cumulative thermal units, biomass productivity index, vernalization times, freezing, rainfall, and day length of each meteorological station were determined and their map was drawn. After weighting maps using hierarchical method, the final map was developed with ARC-GIS software. Results showed that sugar beet plants are susceptible to bolting in Baft, Bardsir and Shahr Babak cities; however in southern parts of the province, sugar beet plants could not receive required vernalization temperature. Less than 50 mm precipitation during the growing season may decrease the feasibility of sugar beet planting in these areas. Although, most of the lands with more than 200 mm precipitation are endanger of freezing, inadequate GDD reception, and vernalization occurrence. Based on final zoning map, 19.42% of the lands including Kahnooj, Manoujan, Anbar Abad, southern part of Jiroft, East of Bam, and south of Baft are classified as prone areas. Remained areas were regarded as proper (22.67%), medium (21.76%), and improper (36.15%) for autumn-sown sugar beet planting. In conclusion, autumn-sown sugar beet planting can be performed in most parts of the province.

The present study aimed to evaluate different Beet necrotic yellow vein virus (BNYVV) genotypes in sugar beet research stations in Iran including Toroq, Zarqan, Miandoab and Ekbatan. Some samples were also collected from sugar factories’ field in Torbat-e Jam, Nahavand, Kamalabad, Naqadeh and Qazvin and also sugar beet fields in Arak. A total of 58 infected sugar beet root samples were collected. In addition, 30 soil samples were collected from sugar beet fields in Moghan, Toroq, Zarqan and Kamalabad, and a susceptible cultivar was planted in them to determine the causal agent type. To detect type A or B of the virus, TGB region of the virus genome was multiplied using multiplex-PCR. Moreover, partial multiplication of RNA5 using RT-PCR and specific primers was performed to detect type P or J. Only 324 bp fragment was multiplied using multiplex-PCR and specific primers designed for type A or B. Therefore, among 88 samples, only type A was detected. No BNYVV isolates containing RNA5 was observed in any of the samples.

In order to investigate the effect of vermicompost tea application on of the reduction of stress effect and improving sugar beet performance, a field experiment was conducted in split plot arrangement based on randomized complete block design with three replications at two regions including Shahrekord University and Shalamzar in 2015. Main plots consisted of three irrigation levels including 100%, 75% and 50% irrigation based on plant’s water requirement and sub-plots were allocated to three soluble including 27 and 54 lit ha-1 vermicompost tea application and sprayed with water (control). Result showed that foliar application of vermicompost tea increased membrane stability index, SPAD value, leaf area index, leaf number, root diameter, shoot and root dry weight, white sugar content, root yield and sugar yield. Water stress decreased all the above mentioned traits except white sugar content. Interaction between irrigation treatment and vermicompost tea application showed that the highest membrane stability index, SPAD value, root diameter, and root yield was achieved with 54 lit ha-1 vermicompost tea application × 100% irrigation based on plant’s water requirement. High correlation was observed between membrane stability index, SPAD value, leaf area index, leaf number, and root diameter with root dry weight.

Relying on knowledge power and its management, organizations can maintain their long-term advantages in competitive arena. Knowledge management has a lot of persistent consequences. Despite the fact that knowledge management plays a vital role in survival of organizations and that access to a deep knowledge and understanding at all levels is a prerequisite for success of organizations in world trade, most organizations have not yet paid serious attention to the innovation and knowledge management. Also, the point to notice is that organizations are not currently valued on the basis of their performance but their value is something that they are able to do it. In this paper, factors and indices forming the knowledge management at Sugar Beet Seed Institute (SBSI) were assessed, analyzed and prioritized and the rate of success for each factor and index was defined and the gap existed at each level was determined. The descriptive-survey research method was used in this study. The statistical population consisted of 31 out of 50 people including members of scientific board and experts. A questionnaire containing 35 questions and 8 dimensions was designed on the basis of the “Building Blocks of Knowledge Management” model and the factors were prioritized by Analytical Network Process (ANP). Considering the output of the network analysis and according to the views of experts, the knowledge evaluation, knowledge sharing and knowledge identification factors were found to be of the first, second, and third priority, respectively, at SBSI. Finally, suggestions were made to improve the current situation with the most important approach being establishment of knowledge management system in the Institute and training of staff.

Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania, is one of the most important viruses influencing sugar beet root in Iran and other parts of the world. A high number of studies has been done on this disease and several resistant cultivars were introduced. In the present study, the physiological changes in two resistant and two susceptible sugar beet cultivars in interaction with this virus was studied. ELISA test results showed that susceptible cultivars had significantly higher virus concentration compared with resistant cultivars. Resistant cultivars showed significantly lower variation in fresh and dry root weight, chlorophyll and antioxidant content. Resistant cultivars showed higher variation in carbohydrate content, total phenol and protein compared with control. In general, BNYVV stimulates a prompt response and more physiological changes in resitant cultivars compared with susceptible ones.

In regions with autumn-sown sugar beet planting, rainfall occurrence during sugar beet growth, especially in winter, has an economic and significant role in supplying the required water. This study was conducted to determine rainfall as well as early and late irrigation proportion on sugar beet performance in randomized complete block design with three replications in Safi-Abad Agricultural Research Center in 2005-06. Treatments were composed of five irrigation levels including irrigation after 100, 150, 200, 250, 300 mm evaporation from evaporation pan (I1-I5, respectively), no-irrigation in spring (I6), seedling emergence by rainfall and spring irrigation after 100 mm evaporation from evaporation pan (I7), irrigation during the growing season after 100 mm evaporation from evaporation pan (I8) and no -rainfall as well as -irrigation in spring (I9). Significant difference was observed among treatments for quantitative and qualitative traits (P < 0.01). The highest root yield (98.9 t ha-1) and sugar yield (12.4 t ha-1) was obtained in I8 and the lowest root yield (55.7 t ha-1) and sugar yield (6.8 t ha-1) was observed in I7 treatments. The highest (16.1%) and the lowest (14.9%) sugar content was observed in I4 and I1 treatments, respectively. The highest and the lowest water use efficiency for root and sugar yield was belonged to I6 and I7, respectively. Rainfall occurrence had significantly increased root and sugar yield and also improved some qualitative traits such as K content, purity, and molasses sugar. The contribution of rainfall, irrigation on early and late of growing season on root yield were 12.3, 76.9 and 22 t ha-1, respectively and their contribution on sugar yield were 2.3, 9.9 and 2.5 t ha-1, respectively. Therefore, it seems that early irrigation plays an important role on sugar beet yield formation and spring irrigation and rainfall occurrence are in next ranks.
