Other claims from this paper (8)
- Intervention effect Amaranth field uniformity fell from 70% at 0.2 million seeds/ha to 60% at 1.2 million seeds/ha, a 10% decrease.
- Intervention effect At the seedling stage amaranth had 14 plants at a 0.2 million seeds/ha sowing rate, rising to 72 plants/m2 at 1.2 million seeds/ha.
- Intervention effect Amaranth plant survival during the vegetation period fell sharply with increasing sowing density, from 86% at 0.2 million seeds/ha to 45% at 1.2 million seeds/ha.
- Observation Before harvesting, amaranth plant density was adjusted to 12-32 plants/m2.
- Observation The best combination of yield structure elements was 21 plants/m2, with a grain weight per plant of 20.4 g.
- Observation The best combination of yield structure elements was also found at 26 plants/m2, with a grain weight per plant of 16.1 g.
- Observation The highest grain yield of amaranth variety Kharkivskyi 1, 4.28 t/ha, was obtained at a sowing rate of 0.4 million seeds/ha.
- Observation The highest grain yield of amaranth variety Kharkivskyi 1, 4.20 t/ha, was obtained at a sowing rate of 0.6 million seeds/ha.
