Camelina sativa (L.) Crantz is a valuable crop with good drought resistance and has been proposed for cultivation in Organic farming system. The development stages of camelina, pea, and vetch grown as sole and mixed crops, and the existing weeds S. halepense and S. viridis in a field plot experiment were under evaluation. The trial was stated in the experimental field of the Agricultural University of Plovdiv, Bulgaria. On the last reporting date the camelina genotypes 'Luna' and 'Lenka' entered the beginning of the flowering stage, and the Bulgarian landrace showed better development and was in the full flowering stage. The pea and vetch were in the full flowering stage as well. The development stages of the mixed cropping systems were the same as the growing stages of their sole crops. The mixed cropping system of the well-developed Bulgarian camelina landrace grown in a mixed cropping system with pea and vetch suppressed the growth and development of the weeds reported. In the sole crops, the reported weeds developed faster and accumulated a greater amount of biomass.
