The yield gap that normally exists between organic and conventional production is caused by different crop specific factors. The main yield limiting factor in cereals and tubers is nutrient availability, and especially nitrogen deficiency leads to yield reductions. Weeds and diseases can cause major yield losses in legumes, and in oil crops attack of insect pests may limit yield significantly. Each group of crops show variations in susceptibility to the different yield limiting factors and choice of crop variety and crop species, mixing of varieties or species as well as the design of crop rotations play a major role for crop yields and qualities.
