To improve the resource-saving technology of growing soybeans in the conditions of the Central Forest-Steppe of Ukraine through the effective application of the main tillage systems and optimization of the fertilization system
popup.description2
The generalized results of the research indicate a significant influence of the main tillage system, different doses of fertilizers and weather conditions on the growth, development and formation of productivity of soybeans of the Siverka variety. Against the background of surface long-term tillage and traditional plowing, soybean seedlings were obtained 3-4 days earlier, the TVP decreased by two days (99 days) compared to the no-till system (101 days) and the maximum values of linear plant growth (67.7-79.0 cm). Favorable parameters of soil density (layer 0-30 cm) during the growing season of soybeans under surface tillage were determined, which was 1.23-1.28 g/cm3 with a total tillage of 51.02-53.06 % and aeration gaps of 29.10-40.82 %.
The supply of mineral nitrogen (Nm) during the growing season of soybeans was low, medium and high; mobile phosphorus and exchangeable potassium - medium and high levels. In the flowering phase, the greatest use of nutrients by plants during surface cultivation was revealed, in particular mineral nitrogen (Nm) by 5.0-8.7 times, P2O5 - by 1.3-1.6, K2O - by 1.67-1.81 times.
Under very dry summer conditions (GTC 0.16), the highest values of individual productivity (IP) of one plant (4.14-7.91 g) were provided by surface cultivation: 14.8-27.2 pcs of beans, 30.0-55.4 pcs of seeds, 137.9-143.1 g of 1000-grain weight. The application of mineral fertilizers in doses of N45P45K45 and N60P60K60 under all tillage systems contributed to an increase in the indicator by 1.39-1.55 and 1.48-1.92 times, respectively.
The maximum yield level (2.54 and 2.50 t/ha) and the increase in additional yield of 0.65 t/ha (34.4%) and 0.63 t/ha (33.7%), protein yield per unit area - 1.07 and 1.04 t/ha, oils 0.55 and 0.54 t/ha) were provided by surface continuous cultivation to a depth of 8 cm and traditional plowing (20-22 cm). The lowest individual productivity (3.16-4.72 g/plant) and yield (1.34-1.78 t/ha) were obtained under no-till systems.
