The level of production is determined by the interaction between plants’ biological limits and by the influence of technological elements applied. Upon harvesting we made measurements concerning the values of some pheno-typical features characteristic of the Attila winter oil rape cultivar under study. The main components of the yield in winter oil rape are the number of main ramifications per plant, the number of siliques per plant, the number of seeds per silique, the number of plants per m 2 , and the average volume of a seed.
