the main objective of this research was the measurement of soil characteristics, land evaluation and determination of potential yield of sugar beet in yekanat plain of marand. for doing this, firstly, yield potential of sugar beet was estimated by fao method and secondly land evaluation of different soil units for sugar beet cultivation was determined by parametric method. results showed that m...

in drought stress condition, it is important to estimate the n and k requirement of sugar beet. a drought-tolerant sugar beet genotype, bp karaj, was evaluated in split plot factorial design based on a randomized complete block design with four replications at motahari research station, karaj, iran for three years. main plots were allocated to irrigation treatments including normal irrigation (...

this study was conducted to determine the effect of variable nitrogen supply on yield parameters of two sugar beet varieties, as well as on biomass allocation to different parts of sugar beet plant at safi-abad agric. res. center during 2003-4 and 2004-5. five nitrogen rates (0, 60, 120, 180 and 240 kgha-1) and two monogerm sugar beet varieties (shirin and rasol) arranged as factorial in a rand...

in order to evaluate some agronomical management on weed control in sugar beet this experiment was conducted at safi-abad agr.res.center, dezful in 2002 and 2004. tow planting dates, september 16 and october 12 and five cultivator applications, one and two time application at 4-6 and 6-8 leaf stages, respectively and once plus hand hoeing, weedy and weed free checks arranged in split plot desig...

this research was carried out to evaluate the effects of some morphophysiological traits on white sugar yield of 10 commercial sugar beet (beta vulgaris l.) varieties. all experiments were conducted in four important sugar beet growing areas in iran, i.e. moghan, khoy, karaj and zarghan in 2006 and 2007. the experiment was arranged as a randomized complete block design with three replications i...

In this study, the harvest scheduling problem of a group of cane growers in Thailand is addressed. Each member in a group is required to consistently supply sugar cane to a mill for the entire harvest season. However, the current scheduling does not account for the time-variant cane production of each cane field, which leads to unequal opportunities for growers to harvest. A portion of growers ...

this research was conducted in order to evaluate genetic diversity, and screening the tolerant genotypes of sugar beet subjected to continuous and severe water stress in the experimental farm of sugar beet seed institute (sbsi) in karaj in 2008. the experimental design was a randomized complete block with 6 replications. fifteen o-types which were tolerant to drought plus 5 (check) genotypes we...

in order to study the effect of solitary and combined application of two types of green manure, cow manure, barvar-2 phosphate fertilizer and conventional chemical fertilizer on some of the qualitative and quantitativeproperties of sugar beet, an experiment was conducted at the research farm of shahrekord university in 2013. the experimental design was randomized in a complete block design with...

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...
