“…Thus, with a speed of 3km h -1 the best seed deposition was obtained, but with the lowest operational yield. Ferreira et al (2019) obtained similar results, and the speed with the best seed deposition was 3.5 km h -1 .…”

“…To achieve high levels of productivity, it is necessary to apply good practices for the implantation of crops (Marques Filho et al, 2020). Among the agricultural operations of importance for the corn cultivation, sowing represents the basis of formation and support for the beginning of the crop cycle (Alonço et al, 2015;Ferreira et al, 2019).…”

In sowing operation, it is essential to control the factors that can affect the quality of seed and fertilizer deposition. These factors range from the correct choice of dosing mechanisms to machine regulation and operating speed control. The present research aimed to analyze the influence of sowing speed on the productive performance of the corn crop. The study was carried out at Fazenda São Geraldo, in the municipality of Boracéia, São Paulo. Four operating speeds 3, 5, 7 and 9 km h -1 were applied in a seeder, with a mechanical horizontal seed meter. The experimental design was carried out in strips. The results showed that sowing operational speed directly influences the final corn yield. There is a positive correlation between sowing speed and reduction in seedling emergence. The speed of 3.0 km h -1 showed the best results for seed deposition and yield. The speeds of 5, 7 and 9 km h -1 presented a reduction of 14.8, 42.5 and 67.2 bags per hectare.

“…To distribute the seeds individually in regular spacing, precision seeders are used (Francetto et al, 2015;Ferreira et al, 2019;Correia et al, 2020). However, the efficiency of these seeders in the quality of sowing occurs, among other factors, mainly through the mechanisms of activation of the seed meters, which can be mechanical, hydraulic or electric (Damasceno et al, 2017).…”

The present study aimed to evaluate the efficiency of the electric transmission drive of the seed metering mechanism of a precision seeder, in relation to the mechanical drive, in the distribution of corn seeds, and its effects on the development of the crop. The experiment was carried out using precision agriculture techniques - geostatistics - in a plot of 4.19 ha managed under no-tillage system. The area was divided into a grid with 35 points for each treatment (electrical transmission of the seed metering mechanism and mechanical transmission of the seed metering mechanism). To carry out the experiment, a precision seeder consisting of 7 lines was used, configured with 0.45m line spacing, being: 4 consecutive lines by electrical transmission and 3 consecutive lines driven by mechanical transmission. The electrical transmission of the seed dosing mechanism provided, in relation to mechanical transmission, a lower coefficient of variation of the linear distribution of seeds, a lower spacing index with failure, a higher normal spacing index, and a smaller difference in seeding density. As a consequence, the electrical transmission of the seed metering mechanism increased the productivity of the corn crop by 1.33% (87.96 kg ha-1) when compared to mechanical transmission.

“…Dependendo do sistema da velocidade de operação na semeadura, o espaçamento entre sementes depositadas no solo pode ser desuniforme (MIALHE, 2012). Em algumas regiões do Brasil são usuais as semeadoras de precisão com sistema mecânico de distribuição (disco horizontal), o sistema é rotativo e posicionado na horizontal, usa a força da gravidade para manter contato com as sementes, as quais preenchem os alvéolos (furos) do disco e são liberadas uma a uma para o sulco de plantio (Ferreira et al, 2019).…”
