The development of amaranth cultivation technology under arid farming conditions represents a rele-vant research direction. Using results of scientific research and taking into account the specifics of soil and climatic conditions of the Lower Volga region, this work was devoted to studying technological methods of amaranth cultivation for obtaining commercial seeds during the period from 2021 to 2023. The aim of the research was to identify the optimal agronomic practice for achieving maximum productivity of purple amaranth (Amaranthus cruentus L.) for food purposes under conditions of the Saratov Right-Bank Volga region.
It was found that experimental variants with early (first decade of May) and late (third decade of May) sowing dates were characterized by a more accelerated vegetation period. In contrast, the medium sowing date (second decade of May) proved to be the latest-maturing, requiring 126–131 days. It should be noted that during the years of research, sowing in the second decade of May provided maximum seed yield up to 2.04 t/ha, forming the highest level of crude protein content up to 24.6%, in combination with a seeding rate of 150 thousand seeds/ha. At the same time, the profitability level reached 185.3%, which indicates high economic feasibility of applying this agronomic technology.
Keywords: amaranth, seeding rate, sowing date, vegetation period, seed yield, economic efficiency.
