this study aimed at determining the evapotranspiration and crop coefficient (kc) of sugar beet during the plant growth using drainage lysimeter by using water balance and experimental methods for three years in shahrekord. after sugar beet planting and out of lysimeter, evapotranspiration was measured weekly and monthly by measuring the factors of the water- balance equation. results showed tha...

The beet armyworm, Spodoptera exigua, is one of the most important pests of sugar beet in Iran. The aim of this study was to determine the effect of water and nitrogen treatments of sugar beet planton developmental time and fecundity life table parameters of the pest. An experiment was carried out under laboratory conditions (25±2oC, 70±5% R.H. and 12L: 12D) on larvae reared...

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...

Fine-tuned and coordinated regulation of transport, metabolism and redox homeostasis allows plants to acclimate to osmotic and ionic stress caused by high salinity. Sugar beet is a highly salt tolerant crop plant and is therefore an interesting model to study sodium chloride (NaCl) acclimation in crops. Sugar beet plants were subjected to a final level of 300 mM NaCl for up to 14 d in hydroponi...

the first damage of sugar beet ladybird was (bulaea lichatschovi hum.) reported in 1972 from south of russia. in iran, the first report of high damage of this insect on the leaves was reported from sugar beet fields of karaj in 1962. adult ladybird is reddish bown with 3.5-4.5 mm length. thorax has 6 black points. on elytres there are 20 blackish brown spots. the ventral body is black. the ante...

in this study, total factor productivity(tfp) growth of sugar beet in iran during 1989-1990 through 2007-2008 was analyzed, using nonparametric malmquist approach. so, amounts of inputs usage including seeds, fertilizers, insecticides, herbicides, labor, water use and acreage in one hand and output of sugar beet production on the hand were taken into account. results showed that sugar beet prod...
