“…In this research, the shape of seeds was not evaluated, however, this variable needs to be better investigated due to different sowing speeds. Souza et al (2019) found decreasing relationships of seed deposition uniformity between velocities 7.2 and 8.6 km h -1 . The authors also noted that furrower depth affects seed deposition.…”

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.

“…Proper seed deposition in the sowing row, with adequate spacing and depth is known as plantability (Bertelli et al, 2016). Plantability is important for the corn crop, as it determines the crop's productivity (Souza et al, 2019). In addition to sowing, speed and feeder models can affect corn productivity (Cortez et al, 2020).…”

“…Segundo Lambrecht et al (2017) os mecanismos sulcadores têm a função de abrir o sulco e depositar em profundidade adequada o fertilizante e a semente, proporcionando condições ideais para germinação, emergência e crescimento da planta. O desenvolvimento inicial das plântulas depende de um bom leito de semeadura e do microclima em torno da semente, fatores Research, Society and Development, v. 11, n. 6, e20111628789, 2022 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v11i6.28789 3 que podem ser alterados pelo uso dos diferentes mecanismos de abertura de sulco (Santos et al, 2016;Souza et al, 2019).…”

Considerando que diversos fatores podem influenciar no processo de semeadura. O objetivo foi avaliar o desempenho energético e operacional do conjunto trator-semeadora-adubadora na semeadura do milho em função de dois mecanismos sulcadores e quatro coberturas do solo. O estudo foi conduzido no Departamento de Engenharia Agrícola da Universidade Federal do Ceará - Campus do Pici. O delineamento experimental foi em blocos ao acaso, os tratamentos consistiram em dois mecanismos sulcadores (disco e haste) e quatro coberturas do solo (crotalária, sorgo, capim mombaça e solo sem cobertura) com quatro repetições. As seguintes variáveis foram analisadas: força e potência na barra de tração, área mobilizada, profundidade de atuação dos mecanismos sulcadores, resistência específica operacional, velocidade de deslocamento, capacidade de campo operacional, patinamento dos rodados dianteiro e traseiro do trator, deslizamento do rodado da semeadora-adubadora, consumo horário de combustível, consumo operacional, consumo específico e consumo por área mobilizada. A área mobilizada foi igual para os dois tipos de mecanismos sulcadores. O mecanismo sulcador tipo haste demandou maior força e potência do conjunto trator-semeadora-adubadora e apresentou maior profundidade de atuação, o que proporcionou menor velocidade de deslocamento. Com relação aos mecanismos sulcadores para consumo horário e consumo operacional, não houve diferença estatística. As plantas de cobertura não influenciam no desempenho energético e operacional do conjunto trator-semeadora-adubadora, exceto para o deslizamento do rodado da semeadora-adubadora. O mecanismo sulcador tipo disco proporcionou melhor desempenho operacional e energético para o conjunto trator-semeadora-adubadora, exceto no consumo específico e consumo específico por área mobilizada.

“…Sowing quality is related to such operational factors as the furrowing mechanism of the planter-fertiliser, displacement speed, and sowing depth (SOUZA et al, 2019). When sowing maize, these settings are even more important due to productivity being strongly dependent on seed distribution by the planter (VIAN et al, 2016).…”

“…The type of furrowing mechanism together with furrowing depth can affect the speed of emergence index and the population of maize plants per hectare (SOUZA et al, 2019). Due to its role in turning the soil, the type of furrower influences the tractive force (TRICAI et al, 2016), with shanks possibly requiring greater tractive effort than discs (FRANCETTO et al, 2015;MILAGRES et al, 2016).…”

The search to optimise agricultural systems by adapting mechanised sets for sowing maize, is essential for improving operational performance, energy efficiency and initial crop establishment. The aim of this study was to evaluate the performance and sowing quality of a planter-fertiliser for maize, in a dystroferric Red Latosol managed under reduced tillage, as a function of the type of furrower, depth of seed deposition and operating speed of the planter. The experimental design was completely randomised, in a split-plot scheme with three replications, where the plots represented the type of furrowing mechanism (shank or double-disk) and the subplots represented three displacement speeds (3.20, 5.15 and 7.32 km h -1 ) and two sowing depths (35 and 40 mm). The best sowing quality for second-crop maize, the lowest power requirement at the tractor drawbar, the lowest specific and hourly fuel and consumption time, and the lowest travel reduction ratio are achieved when the tractor-planter-fertiliser set is configured to use a double-disk at a sowing depth of 35 mm. The adoption of higher displacement speeds results in increased operational and effective field capacity, as well as a lower energy demand when the tractor-planterfertiliser set develops speeds close to or greater than 7.32 km h -1 , irrespective of furrower type or soil depth.
