Abstract

AbstractThe efficiency of grain crops production largely depends on the technical and technological level of agricultural machinery used by enterprises of the agro-industrial complex, among which seeders are among the most demanded and structurally complex. Grain seeders are available in two basic configurations—monoblock (classic seeders) and single-unit seeders, which are now commonly called seeding complexes. The machines of these two groups differ significantly from each other not only structurally, but also in terms of operation and functional indicators. Therefore, in terms of optimizing the design, production and operation of seeders, it is important to have an objective comparative assessment of their technical characteristics and performance indicators. The study was carried out by statistical processing and analysis of data from 70 test reports of seeders that passed certification at mechanical test stations of the Russian Federation in the 21st centure, the analysis of which showed that, in terms of agrotechnical and operational indicators, the seeding complexes are somewhat inferior to “classic” grain seeders, but at the same time they allow the implementation of rowless method of sowing grain on an unprepared stubble background, which are the most promising from the point of view of modern production experience.KeywordsAgrotechnical indicatorsSeeders of various assembliesProduction efficiencyGrain crops
