Abstract

The field experiment was carried out at the Scientific Agricultural Research Center, Der Al Zur, Syria, during the growing seasons 2009/2010 and 2010/2011, to determine the effect of planting method on some productivity and quality traits of two sugar beet varieties, one was monogerm i.e. Dita, while the other was multigerm i.e. Reda. The experiment was sown in three methods i.e. ridges (50 cm), ridges (100 cm), and rows, each planting method with plant distance (20 cm between plants). The experiment was laid out in a split plot design, with four replications. The combined analysis exhibited significant effect of the planting method (M) and non significant effect of the varieties (V) for most of the studied traits. The results showed that planting in ridges were more important compared with sown in rows  however, planting  in ridges with width 100 cm caused  an increase in root and sugar yields, and sucrose% (65.9 ton/ha, 10.1 ton/ha and 17.5 %, respectively). ).  We can consider planting in ridges the best planting method in summer season in Der Al Zur governorate in Syria.

Keywords: Planting method, Productivity and quality traits, Sugar beet varieties.
