general combining ability of sugar beet parents were determined for different quantity and quality characteristics.forty six sugar beet hybrids obtained from crosses of 23 diploid pollinators with two male sterile parents as tester together with three checks were evaluated for 10 important agronomic and technological characters at kamalshar research station in karaj in 2004.experiment was carri...

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 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 (...

in order to study the response of new sugar beet hybrids and cultivars to curly top disease in the field conditions, an experiment was carried out in a randomized complete block design with four replications and sixteen treatments in 2007 in fasa. each plot included a hybrid or cultivar planted in three rows with eight meter length and 50cm between- row spacing. after weeding and first thinning...

water and soil salinity in some regions of isfahan, east azerbaijan, and west azerbaijan provinces and also other parts of the iran are the main hindrance for crop planting. seeds of the tolerant crops to salinity such as cotton and sugar beet may have optimal germination and give acceptable performance if they become far from salt accumulation areas. to evaluate the effects of different planti...

in order to determine the optimum sowing and harvesting dates of two autumn sugar beet cultivars (bete vulgaris l.) and develop the planting area of this crop, the present research was conducted in fasa, iran during 2005-2008. the experiment was carried out in split-split plots based on randomized complete block design (rcbd) with four replications. three sowing dates (september 27, october 17 ...

in order to study the effects of farm yard manure (fym), sulfate of potassium (sop) and boric acid on quality and quantity of sugar beet, an experiment was conducted in split plot factorial with four replications during 3 years (1999-2001) in bardsir- kerman. the fym was the main plot in 3 levels: 0, 10 and 20 ton.ha-1. sop was applied at levels, 0 ,75 and 150 kg.ha-1  and boric acid at levels ...

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...
