Technology for modeling sunflower cultivation using various basic tillage systems

Purpose. To predict the efficiency of sunflower cultivation depending on the adopted processing system at the enterprise and the level of its mechanization, taking into account the criteria of intensity and depth.

Specifications. The model provides for the use of resources for preliminary assessment of the effectiveness of using different systems of main soil cultivation in terms of their impact on the quality and level of sunflower yield and is based on the logistic system of the results of a long-term stationary study of the role of depth and method of main soil cultivation due to abiotic environmental factors. In the experimental base system, a system of classical autumn plowing was used using trailed plows of the PLN-6(7)-35 type, the use of deep loosening to a depth of 14-16 cm using classical variants of subsoilers such as using disks to a depth of 10-12 cm in two trace (classical disc harrow BDT-7. Agrochemical parameters of the soil cover of the enterprise and long-term trends in the hydrothermal regime of the territory are used for modeling).

Application area. Agricultural enterprises of various forms of ownership, research institutions.

Advantages. A flexible system for selecting the most effective option for primary tillage systems, which is based on a multi-parameter assessment system and long-term field regional studies.

Technical and economic effect. The use of an optimal system of basic soil cultivation allows not only to adjust the level of cost of the technology itself, but also affects the intensity of plant growth processes, the spread and branching of the root system, and ultimately determines the level of sowing productivity and oil content of seeds of various sunflower hybrids. The use of modeling data will contribute to the maximum realization of the genetic and biological potential of industrial crop plants and an increase in yield by 15-25%, which will ensure sustainable sunflower production and will allow the system of highest yield to be adapted to the main soil cultivation options adopted in a certain area.

Description. A model has been created for assessing the efficiency of growing high-intensity sunflower hybrids of various ripeness groups by involving in its variable parameters different-depth basic options for basic soil cultivation (10-12 cm). The effective parameters of such a model are the level of overall productivity of plant biomass formation, their yield for the main products and the manufacturability of the resulting raw materials in terms of quality indicators.
