Influence of soil treatment and mineral fertilizers on structural indicators of summer soybean crops
Year: 2022
Type: article
Abstract: It has been established that on each variant oftillage use of mineral fertilizers have a positive effect on the structural indicators of the yield when sowing summer soybeans. When the soil was cultivated to a depth of 8–10 cm, the number of beans per plant was 3.0–10.2 pieces, the number of grains per plant was 5.7–21.8 pieces, the grain yield per plant was 1.0–3.6 g, the weight of 1000 grains was 7.0–7.4 g; when disking the soil to a depth of 13–15 cm these indicators reached, respecttively, 3.3–11.4 pieces, 6.0–22.5 pieces, 1.2–3.8 g, 3.5–8.0 g; when plowing to a depth of 20–22 cm these indicators increased and amounted to 3.8–13.3 pieces, 6.9–24.9 pieces, 1.7–4.5 g, 4.3–8.6 g and this contributed to an increase in yield compared to control. Thus, the highest structural indicators were obtained when plowing the soil to a depth of 20–22 cm and at a rate of mineral fertilizers N60P90K60 kg/ha of active substance.
