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...

in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...

to determine sugar beet water requirement and the effect of changing the quantity of applied water on some production components, a study was carried out in ekbatan agricultural research station of hamedān, iran in four years (1994-1997) during which optimum water requirement, root and sugar yield, water use efficiency on the basis of root yield, sugar percentage and water use efficiency on the...

understanding the relationship between root yield and other traits in sugar beet may be a crucial step towards successful breeding of this important crop. path analysis provides a useful method in analyzing the genetic and phenotypic coefficients of correlations. this method is able to effectively unveil direct and indirect effects among traits of interest. in this research, root yield, yield c...

in order to study the possibility of control of heterodera schachtii  in sugarbeet fields through integration of rotation with non- host crops and resistant catch crops and their effects on quantitative and qualitative traits of sugarbeet, this study was started from 2002 for three years in esfahan province. the experiments were carried out in a randomized complete block design with eight treat...

in order to evaluate salinity tolerance in 20 sugar bee genotypes, an experiment was conducted in two fields with salinity (ec= 12 ds/m, ph= 7.6) and non-salinity stress, in the form of rcbd at miandoab agricultural research station. different morphological and physiological traits such as root yield, sugar percentage, white sugar percentage, molasses, n, na, k, syrup purity and green cover per...

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...

planting pattern can be adjusted by changing row spacing and row width, one row and two- row planting and plant interval on rows. in order to obtain the optimum planting pattern of a monogerm hybrid cultivar and its effect on the quantitative and qualitative characteristics of this cultivar, an experiment was conducted in two years (2001-2002) in zarghan area of farsprovince. the measured chara...
