Agrotechnical performance indicators of the asymmetric working body of a fallow cultivator

Abstract

BACKGROUND: Obtaining sustainable and high-quality harvest is important for the production of agricultural products. It is known that up to 40-45% of all energy costs are spent on preparing the soil for sowing when cultivating agricultural crops. Surface-fallow tillage is a subtle technological process, it influences on normal distribution of the seed material in depth and, as a consequence, the further uniformity of seedlings. To ensure the process flow of pre-sowing preparation of the soil for sowing, a new asymmetric working body for a fallow cultivator was developed in the Donskoy Agrarian Scientific Center, the structural subdivision of the SKNIIMESKh, Zernograd. There is a task to conduct a comparative analysis of operation of the new working body with V-shaped sweeps when preparing the soil for sowing.

AIM: Conducting a comparative analysis of operation of a serial V-shaped sweep with the new proposed asymmetric working body of a fallow cultivator by field research in the fields of the Donskoy ANC.

METHODS: The research in the fields of Donskoy ANC was conducted according to the GOST 33687-2015 “Machines and tools for surface tillage” regional standard. Well-known statistical extrapolation methods implemented in the Microsoft Excel environment were used for data processing.

RESULTS: The optimal operating parameters of the new proposed asymmetric working body have been determined in comparison with the serial working body of a fallow cultivator.

CONCLUSIONS: According to the conducted laboratory and field studies, the parameters and operating modes of the new asymmetric working body were obtained.
