Effects of different soil environment on yield and quality of sugar beet

The experimental results showed that average root yield,sugar content,sugar yield of sugar beet in the nondisease field increased by12230.6kg /ha,4.46 o S,3122.4kg /ha respectively than that in the disease field;T test showed that the yield and quality of sugar beet were affected by different soil environment ,and their sequence was sugar contentsugar yieldroot yield,there were94.1%,84.7%and50.7%of the lines reached the significant and the more significant difference respectively;the variance analysis results showed that the significance of difference among lines in the root yield and sugar yield in the disease field was on the whole the same with that in the nondisease field,but that of sugar content in the disease field was not completely same with that in nondisease field,the disease field can make significant or more significant difference among lines in sugar content .Two kinds of field resulted in extreme ly significant difference of the root yield and the sugar yield in feed beets and mono-germ lines of sugar beet.
