Year: 2021

Type: conference-paper

Abstract: In the experiment, four varieties of winter wheat (Don 93 – standard, Krasa of Don, Lilit, Kapitan) and four levels of mineral nutrition (1. Ammophos 60 kg/ha when sowing; 2. Ammophos 60 kg/ha when sowing, Polydon Biouniversal 0.5 l/ha in the tillering phase, Polydon Biouniversal 0.5 l/ha in the earing phase; 3. Ammophos 60 kg/ha when sowing, spring tillering ammonium nitrate 130 kg/ha, Polydon Biouniversal 0.5 l/ha in the tillering phase, Polydon Biouniversal 0.5 l/ha in the earing phase; 4. Ammophos 60 kg/ha during sowing, spring tillering ammonium nitrate 130 kg/ha) were considered. According to the level of mineral nutrition, the lowest biological yield was formed at the first level of nutrition. At the third level of nutrition, the largest biological yield was formed. On average, for three years of research, it was in the Don-93 variety by 0.54 t/ha more than at the first level, in the Kapitan variety by 0.66 t/ha more than at the first level, in the Krasa of Don variety by 0.81 t/ha more than at the first level and in the Lilit variety by 0.89 t/ha more than at the first level.
