Effects of steckling weight and planting density on sugar beet (Beta vulgaris L.) monogerm seed yield and qualitative traits.

In order to determine the effects of steckling weight and planting density on sugar beet monogerm (Cv. 9597) seed quantitative and qualitative characteristics, this experiment was carried out in Ardabil Agricultural Research Station-Iran (38 degrees 30'N and 48 degrees 30'E) during 2 years (2002-2003). In the study, steckling weight (main-plot) in three levels including 100, 100-200 and 200-300 g and planting density (sub-plot) in three levels including 40, 50 and 60 cm were used in a split-plot experiment based on the RCBD (Randomized Complete Blocks Design) with 5 replications.
