to study the effect of variable irrigation in spring on water use efficiency, quantity and quality of root and sugar yield of two sugar beet cultivars shirin and rasolan, an experiment was conducted at safiabad agriculctura research center during 2003-04 and 2004-05 cropping seasons. the experiment was designed in  a split plot with four replications in which five water supply treatments 25, 50...

to evaluate yield and productivity indices of maize and sugar beet intercropping with different planting ratios, a field experiment was conducted in randomized complete block design with three replication at hamedan province in nahavand, in 2013. the planting ratios were 100:0, 75:25, 50:50, 25:75 and 0:100 (maiz: sugar beet) using replacement method. results showed that intercropping had signi...

the main objective of this study was to investigate the economic efficiency of investment in sugar beet breeding research in iran. the required information including the value and cost of sugar beet production in 2010 and the budget allocated to the sugar beet breeding research were obtained from the office of statistics and information technology of ministry of jihad-e-agriculture and agricult...

in this study, analysis of actual data collected from sugar beet hybrid monogerm seed producers in the 2001 growing season and laboratory seed samples showed that delay in steckling sowing resulted in the reduction of raw and pure sugar beet seed yield and the increase of undersize seed portion. non-significant effect of sowing dates on unkernel seed percent showed that the high temperatures wi...

in order to evaluate the efficiency of empirical competition models for simulation of sugar beet (beta vulgaris l.) yield at interference with redroot pigweed (amaranthus retroflexus l.), a factorial experiment based on randomized complete block design with three replications was carried out. factors were weed densities (d1=1, d2= 4, d3= 8, d4=12 and d5=16 plants m-1 of row) and relative time o...

due to the scarcity of water resources, the need for sustainable development of drip irrigation tape is essential in iran. a number of drip irrigation tape systems used in sugar beet fields of isfahan and chahar mahal va bakhtiari provinces were evaluated and were compared with furrow irrigation methods in two consecutive years. the actual water use efficiency (wuesy, wuewsy) in lower quarter, ...

the main objective of this study was to develop an optimal cropping pattern for sugar beet growers in fasa district (fars province) and to investigate sugar beet importance in cropping pattern. regarding the effect of risk on producer's decision, two risk sources including price and yield were considered. data was obtained from fasa district producers in 2008. in this study multi-objective...

in 2006 the sugar beet crop production iniranwas largest ever.  in this year, 6,603,383 t with average sugar content of 16.84% delivered to the 32 sugar factories during five months of the campaign. from begining of the campaign until early–november there was balance between the amount of sugar beet delivered and that of processed by the sugar factories.  however, delivered beet to the factorie...
