Abstract. Amaranth is called the culture of the future due to its unique food,
feeding and medicinal properties. The acreage of Amaranth in Ukraine is
very small, which can be explained by the lack of adaptive cultivation
technologies, especially for growing this crop for grain. The purpose of
the research was to establish the most productive cultivars for growing in
the conditions of excessive and suffcient moisture in the western forest-
steppe on dark grey soil. For this purpose, feld research was conducted in
the experimental feld of Lviv National Agrarian University. The total area
of the site was 30 m
2
, recording – 20 m
2
. The studies were conducted in
three repetitions. The authors studied seven of the most common cultivars
of Amaranth in Ukraine: Kharkivskyi 1, Lera, Sam, Studentskyi, Polishchuk,
Aztec, Ultra. It was established that the yield of amaranth considerably
depended on the hydrothermal conditions of the year. It was lower in years
with excessive rainfall in the frst half of vegetation (2019 and 2020). The
highest grain yield (2.46-4.35 t/ha) was formed in 2021 when the amount
of precipitation in May, June and July was within the normal range. A strong
inverse correlation was established (r=-0.82–r=-0.95) between the yield
of amaranth cultivars and the amount of precipitation. The highest grain
yield (4.03 t/ha) among the studied amaranth cultivars was obtained in
Kharkivskyi 1. The lowest yield was formed in the Ultra cultivar (1.97 t/ha),
which is less than in the Kharkivskyi 1 cultivar by 2.06 t/ha. The study of
elements of the yield structure showed that the height of the plant had a
positive effect (r=0.63) on the level of amaranth grain yield, while average
relationship was observed between panicle length and yield (r=-0.36).
The weight of 1000 seeds in the cultivars ranged from 0.74-0.88 g. The
low mass of seeds per plant had the greatest impact on yield (r=0.99). The
highest yield of amaranth of the Kharkivskyi 1 cultivar was formed with
the following ratio of the main elements of the crop structure: the number
of plants – 21 p/m
2
and the mass of seeds from the plant – 19.2 g. To
obtain a high stable yield of amaranth grain, additional research is required
to clarify the main elements of cultivation technology for these soil and
climatic conditions
