Some morphological characteristics of Amaranth species were studied in 2011-2012. The seeds were collected from different agroecological zones of the country - Plovdiv, Sofia and Dobrich regions, from crops of sunflower and maize. Our research has shown that a large number of seeds in 1 g formed Amaranthus hybridus L. (2038), compared with Amaranthus blitoides L. (824). The mass of 1000 seed was higher in Amaranthus blitoides L. (1.47g). The phenological development of Amaranthus hybridus L. and Amaranthus blitoides L. was carried out. The main phenophase of weeds was observed. The study results show that for the whole growing season Amaranthus hybridus L. requires lower temperature sum (1308.0°C), compared with Amaranthus blitoides L. (1606.5°C).
