Investigations on the effect of number of plants/area on the yield potential of rapeseed plants (Brassica napus L. var. napus) Based on field experiments with winter rapeseed, the effect of number of plants per area on yield potential and components of yield were investigated. The dependence of yield from number of plants per area before and after winter was analyzed by manipulating the number of plants immediately after sowing and in spring before beginning of growth. The number of plants per area was varied between 10 plants/m2 till 185 plants/m2. The results show that the yield potential is partly dependend on the growing conditions before winter as influenced by the number of plants per area; the yield potential declines with increasing number of plants/area before winter; affected are the number of siliquae producing lateral shoots, the number of siliquae per shoot and seeds per siliqua. The growing conditions before winter, in this way control the capacity of the rapeseed plant to utilize environmental factors in the main growing period. 50–100 plants/m2 before winter and 45–90 plants/m2 after winter are within the compensation capacity of rapeseed plants.
