ABSTRACT

Sugar beet seeds were treated by four different methods: rubbing, washing, priming and priming in combination with rubbing. Seeds were sown in a field for estimation of field emergence, yield and variability of single root weight. Each year the faster and more regular plant emergence was from primed or rubbed and primed seeds. Values of single root variability coefficient ranged from 53.3 to 73.9%. Priming and priming with rubbing decreased the coefficient of root weight variability by 7.1 to 9.2% compared to other methods. Root weight variability coefficient was strongly correlated to the time of field emergence. The shorter the mean time to emergence, the lower the root variability during the harvest. Sugar beet plants which emerged first produced the heaviest roots. Time and sequence of emergence influenced final root weight more than the mean distance to the neighbouring beets in the rows and their mean weight.

Key words: field emergence, seed treatment, sugar beet seed, root weight variability.
