- Opis:
- Amaranth (Amaranthus spp.) is a promising alternative crop, which is gaining more popularity and a more widespread distribution throughout the world. The aim of this study has been to find out how the doses of mineral fertilizers affect the yield and quality of amaranth grain in the wet and warm climate of the Western Forest Steppe of Ukraine. The research was conducted from 2020 to 2022, on an experimental field of the Lviv National Environmental University (LNEU – Dublyany). The soil of the experimental field is Grayic Luvic Phaeozem. The experiment comprised seven different fertilizer treatments: N0P0K0, N40P20K40, N80P40K80, N120P40K80, N160P60K120, N200P80K120, N200P80K160. The tested plant was amaranth of the Kharkivskyi 1 variety. Asystematic increase in fertilizer doses, particularly nitrogen, led to a gradual rise in amaranth grain yield. In the control without fertilizers, the yield was 2.31 Mg ha-1. With an increase in fertilizer application, it rose by 2.57 Mg ha-1, reaching 4.88 Mg ha-1 at the highest fertilizer dose N200P80K160. The grain bulk density was higher (790 g l-1) in the variants without fertilizers, and the lowest when N200P80K160 and N200P80K180 were applied, where it was 755 g l-1 and 750 g l-1. The protein content in amaranth grains increased from 16.2% to 18.9%, reaching its peak under the influence of an increase in mineral fertilizer doses from N40P20K40 to N200P80K160. The starch content decreased from 67.4% on the plot without fertilizers to 64.8% when applying the highest doses of fertilizers, i.e. N200P80K120 and N200P80K160. Statistical models of correlations showed that the doses of mineral fertilizers, especially nitrogen, have a strong influence on the indicators of yield and grain quality of amaranth in the warm and humid climate of western Ukraine. High doses of fertilizers significantly increase yield, but negatively affect the grain bulk density and starch content, while significantly increasing the proportion of protein.
