In order to manage sugar beet fungal diseases, different fields of the diseases were studied in 27 research projects of a program. Based on preliminary resultes of different projects on importance of the fungal diseases, studies were focused on root rot agents, cercospora leaf spot and powdery mildew. Rhizoctonia, Pythium and Phytophthora were identified as important and prevelant root pathoge ...

Rhizomania disease has attracted most attention in recent years. One of the cultural practices that have been suggested to reduce the incidence and severity of rhizomania or to limit the spread of the pathogen includes limiting irrigation duration and increasing frequency. Two separate furrow irrigated experiments in non-infested vs. infested fields (in 2002) and low infested vs. high infested ...

Field experiments were carried out at Dezful (as autumn planting), Karaj, Miandoaab, Mashhad, and Shiraz (as spring planting) in 1382, 1383, and 1384. The experimental design was split-split-plot with a randomized complete block arrangement with four replications. The main factors were planting dates (PD) of 20th Shahrivar, 15th Mehr, and 10th Aban in Dezful, 25th Esfand, 25th Farvardin, 25th ...

Limitation of water resources has affected crop production in semiarid regions in recent years. Although sugar beet is considered as a drought tolerant crop, water deficit stress at various growth stages results in reduced root yield of the crop. One of the most efficient methods for mitigating drought stress in sugar beet production is development and breeding of drought tolerant varieties. F ...

Water deficit is one of the important factors limiting crop productivity in arid and semiarid regions of the world. Therefore, introduction of drought tolerant varieties in agricultural crops including sugar beet is of special priority. One of three components of the hybrid varieties is suitable pollinator parent. In this study, ١٣١ half-sib families ١١٠ and ١١١) were compared, in , (selected ...

Environmental stresses, especially drought and salinity, are among the major factors limiting the production of crops including sugar beet in arid and semi-arid regions of the world. With an annual precipitation of 240 mm, Iran is calssified as a dry region of the world. On the other hand, over 17% of country'a area is occupied by saline soil.Thus, for the production of crops to be economic in ...

In order to evaluate the response of antioxidant defense system of three sugar beet genotypes to drought stress and enhancing management of soil water content, a two-years field experiment was conducted at the Research Site of Sugar Beet Seed Institute in Karaj, Iran during 2008 and 2009. Irrigation treatments arranged in main plots during growing seasons included: 80 mm (I1: as control), 130 ...

Root and crown rot by fungi including Rhizoctonia, Pythium and Phytophthora, most important factors are inhibiting the production of sugar beet. To evaluate the effect of agronomic factors on the reduction of sugar beet root rot experiment was performed in Khorasan Razavi (Torbat jame). Split plot experimental design that the main plot two levels of irrigation (including irrigation 8 days and ...

Nowadays polymers have found wide applications in agriculture. Smart polymeric materials and polymer delivery systems contribute to fight with viruses and other unwanted streses in agricultural industry. The goal of this research was to determine the effects of the synthesized polymers properties on ‪ seed germination and seedling growth of sugar beet (variety Zarghan) in laboratory, greenhous ...
