Effect of Seed Type, Planter Type and Depth of Planting on Sugarbeet Emergence!

Field studies were used to evaluate the effects of three seed types (bare, coated and pelleted), two planter types (Stanhay-Webb RaUye 590 and John Deere 71 Flexi­ planter) and four planting depths (1.25, 2.5, 3.75 and 5.0 em) on the emergence of sugarbeet. Field plots were planted at four different times during April and May of 1989, 1990 and 1991 to simulate seed germination and emergence conditions. When all sites were combined, no significant difference in emergence was found among the three types ofseed tested. The John Deere 71 Flexi-planter provided better emergence than the RaUye 590 planter except at the 1.25 cm depth where emergence was the same. Sugarbeet seed planted at 1.25 and 2.5 cm planting depths had greater final emergence for both planter types tested as compared to the 3.75 and 5.0 cm planting depths.
