Abstract

Seed processing is an important part of seed technology that aims to provide high-quality seeds. In recent years, various methods have been used in Iran to improve the agronomic value of sugar beet seeds, via increasing the seed size and seed coating seed with special insecticides. This study aimed to determine the effect of seed processing and insecticides used for coating on the characteristics of seed germination in the laboratory, seed vigor in the greenhouse (in Karaj), and plant establishment and crop yield in the field (in Karaj and Kermanshah), which was conducted as a factorial design based on completely randomized design (for the laboratory and greenhouse) and randomized complete block design (in the field) with four replications in 2017-18. The first factor was the processing method at two levels of conventional (a1) and special (a2), and the second factor was the insecticide used for coating at two levels of Gaucho (b1) and Cruiser-350 (b2). Results showed that the effect of seed processing method on seed vigor and radicle length was significant (P < 0.01), so that the highest seed vigor and radicle length were obtained in special processing. The location × sampling interaction had significant (P < 0.01) effect on plant establishment. Therefore,  it can be deduced that the seed processing method improves the characteristics related to seed germination and plant establishment. Finally, the results of the present study showed that changing the processing method from conventional to special increased seedling establishment under the greenhouse condition, however it did not have any effect on improving seed germination rate under the laboratory condition.
