Research objective - to assess the impact of sowing time and depth and their interaction on sugar beet germination on loamy, low in humus soils. The trials on sugar beet germination were carried out over 2000-2002 in the Plant breeding collections at Lithuanian University of Agriculture. Soil on trial fields - carbonate shallow gracious IDg8-k(LVg-p-w-ec). Soil textural class is a medium heavy loam, pHKCl - 6.8-7.2, humus content - 14-17 g kgE-1. The obtained data indicated that on soils low in humus soil crust was formed in almost all cases and had a negative impact on germination of sugar beet seeds. The greatest impact was identified in variants of later sowing when at optimum sowing depth 50-67% of seeds germinated. Sowing depth, sowing time and their interaction had statistically significant impact on sugar beet germination whereas sowing depth affected sugar beet germination by 66.1-84.2%. In terms of agronomy the highest beet field germination was obtained when sown early at 3 cm depth.
