in order to assess the heritability of short vegetation period (early maturity) of sugar beet hybrids, an experiment was carried out in randomized complete block (rcb) design with 4 replications in abdolrasoul motahari agricaltural research station of sugar beet seed institute, karaj, iran in 2009. in this research, the heredity of the traits in testcrosses derived from crosses of 18 half sib f...

in order to identify and selection salt tolerant hybrids based on tolerance indices, 17 sugar beet three-way cross hybrids produced by crosses between 17 salinity improved s1 pollinators and a cytoplasmic male sterile (cms) single cross as female, along with three control genotypes were grown in 2007 in rudasht station (isfahan) under saline (12 ds/m and 8 ds/m for water and soil) and non-salin...

in ordet to investigate economic efficiency of five cultural systems in sugar beet crop, including high input, medium input  low input , high  and medium inputs without 3 times irrigation after emergence, an experiment was conducted over  two years  (2002-2003) in agricultural and natural resources research center of khorasan. these systems were analysed by marginal analysis and  linear program...

hargraves-samani method is one of the methods for calculating plant evapotranspiration that needs minimum meteorological data. in order to evaluate et-hs model in determining sugar beet crop water demand in isfahan, an experiment was conducted at research field of department of agriculture, khorasgan branch, islamic azad university, isfahan, iranin 2005. the study was based a randomized complet...

background and objectives: over the last two decades, a large number of researches have been conducted regarding the importance of nitrogen in sugar beet. this indicate that there were needs to investigate more on nitrogen management to achive higher production and quality because less nitrogen application result in reducing yield and high nitrogen application would increase production costs an...

the main objective for development and introduction of the new cultivar was to a achieve a high yielding and adaptative to short growing period or a catch crop, suitable for growing in different areas of iran. after preliminary selections carried out during 1998-2000, 72 foxtail millet populations which had been collected from different parts of iran, were examined and based on different agrono...

this experiment was conducted to evaluate eight new sugar beet genotypes with different drought tolerance responses to three irrigation schemes (including normal irrigation and early season and continuous stressed) in motahari research station of sugar beet seed institute (sbsi),karaj,iranduring 2005-2006. the study was accomplished in a split plot design (irrigation schemes and genotypes as ma...

sowing and harvesting date are the most important agronomic factors that we should pay attention to proper date selection for sowing date in order to achieve good crop establishment and to harvest date in order to achieve the best time for crop quantities and qualities ripening. farmers intend to germinate sugar beet seed at minimum environmental temperature. sowing date affects crop canopy dev...
