The major factor influencing the development, yielding and chemical composition of rape seeds was a variable course of weather in the experimental years. Forecrop exerted little effect on fresh and dry matter of plants after inhibition of vegetation in autumn and its reactivation in spring. The density of pea plants being increased from 75 to 125 per sq. m gave the fresh matter of rape in autumn higher by 10.6 percent, losses in dry matter of rape during winter dormancy by 5.2 percent, number of siliques by 8 percent, mass of seeds from a plant by 13 percent, weight of 1000 grains by 3 percent, seed yield by 7.3 percent, crude protein by 7.5 percent and total protein by 9 percent
