Between 2001 and 2003, a study on the impact of sowing depth and sowing time on the germination of winter rape was completed in the Plant Breeding Collection on Experimental Station at Lithuanian University of Agriculture. In terms of agronomy, the highest values of seed germination of winter rape (80.6-81.1%) were obtained when sowing on the 5th of August (on the second-third day after the harvest of corn undercrop) at a depth of 2-3 cm. If there was no rain after the harvesting of the undercrop, the later sowing time significantly affected the germination of winter rape. Within all years of investigation, an increase in sowing depth up to 4 cm and a more independent sowing time of winter rape decreased their germination more significantly. The research data in practice were estimated by sufficient significance P=0.95 by the module of ANOVA/MANOVA and NONLINEAR ESTIMATION/User-specified regression of the integrated system of data analysis and management of StatSoft Company. The obtained results indicate that dispersions of all variables are equal; the sowing depth, sowing time and the interaction of both factors had a statistically significant impact on winter rape yield, and for sowing depth there was a strong and statistically significant non-linear (second order polynomial) dependence
