Desertification is a global threat to humankind that affects the livelihoods of millions (and possibly billions) of people residing in arid and adjacent areas. Due to the sharp retreat of the Caspian Sea by fifty kilometers from its former shore, the bare and unvegetated loose lands, previously occupied by the sea, turn into a source of dust storms, carrying with them toxic salts harmful to all living creatures of the Caspian adjacent areas. The increasing frequency of dangerous natural phenomena such as dust storms, contrasting halomorphic manifestations, and increasing areas of degraded desert soils dictate the need for research on combating progressive soil salinization. Phytomelioration as well as selection of salt- and drought-resistant plants from natural pastures of the Caspian Sea and study of their adaptive properties to salinity and soil drought are applied as the core reclamation methods of saline soils in rainfed conditions, as they have a joint negative effect on plants due to the fact that they occur together everywhere in the soils of this zone. This paper reveals the causes of abnormal dwarf growth and development in first-year Kochia prostrata and studies the effect of dwarfism on the growth and development of its subsequent years, particularly on its productivity and seed quality. As a result of the research, dwarfism of first-year Kochia prostrata plants is stated to be caused by sowing incomplete seeds. The formation of incomplete seeds is caused by the mowing of the first-year plants or their stratification by animals.
