Introduction
1
In many countries of the world, sugar production is one of the essential aspects of their agricultural economy,
and in the meantime, the sugar beet plant, which is cultivated exclusively as a source of sucrose, plays an
important role. In recent years, many studies have been conducted in Iran on various aspects of crop, breed,
quality and other agricultural characteristics of autumn sugar beet. The results of this research confirm that sugar
beet can be introduced as an important and effective autumn crop in the susceptible periodic system. One of the
important factors in sugar beet root production is the sowing date, which affects the duration of the vegetative
and reproductive growth period and the balance between them, and ultimately affects its quantitative and
qualitative yield, so one of the general policies of the agricultural sector is to increase the production of this
product. Several factors affect the formation of sugar beet yield. One of them is the bolting phenomenon. Flower
formation is a phenomenon that in the sugar beet plant, it is known as bolting. In bolting root yield and root
quality of flowering plants are reduced. The cultivars differ in bolting response. The genotype is important factor
in Occurrence of the bolting phenomenon. Also, bolting rate between sowing dates is different.
Materials and Methods
The aim of the present study was to investigate the quality and strength changes in the sugar beet in order to
assess effect of different sowing dates and cultivars on sugar and root yield. To investigate the effect of planting
date on yield, a field trial was conducted during 2021-2022 in Gonbad Kavous. The experiment followed a split-
