Amaranthus at Interfluve of the Volga and Ural Rivers
Amaranthus is an ancient American Indian crop. The earliest information about it is found in the book series «Monuments of literature», published in the 1970s in Russian. In Russia, cultural amaranth has been tested since the first third of the last century. Weed species of Amaranthus were introduced into Russian territory in the 19-20-x centuries and are burdensome weeds in modern agriculture. The high competitive ability of weed amaranths is determined by their biology. The degree of contamination of arable land with wild amaranth seeds largely hinders the developmentofcultural species. Thequality ofvarieties and the level of seed production of amaranths remains as a problem. The practical experience of growing amaranth is summarized in the Trans-Volga districts of the Volgograd region. It is proposed to develop a preventive set of measures for the destruction of wild amaranths, the development of technology for cultural species cultivating in relation to local conditions and seed production improving of created Amaranthus varieties.
