“…It is inferred that the pressure of the tire on the soil and also the formation of microrelief reduced the contact of the drive wheel with the soil, increasing the slippage. As to the velocities, there was no significant difference, i.e., even with the increase in velocity, there is no increment in the seeder slippage and these results differ from those found by Palma et al (2010), who observed increase in slippage with the increment in velocity.…”

A B S T R A C TAgribusiness daily increases the demand for machinery with better efficiency, seeking to reduce operating costs and improve the quality of the sowing process. The objective of present study was to evaluate the quality of the longitudinal seed distribution and the operating performance of a seeder-fertilizer according to displacement velocity and furrowing mechanism for fertilizer deposition. The assay was conducted in the experimental area of the Department of Agricultural Engineering of the Federal University of Ceará. The experimental design was randomized blocks, in a 2 x 3 factorial, with four replicates with two furrowing mechanisms for fertilizer deposition (double disc and shank) and three displacement velocities (4.7, 6.3 and 8.2 km h -1 ). The results demonstrate that for the quality of seed distribution, the best performance was obtained with the use of the shank at velocity of 6.3 km h -1 . The tractor-seeder set provided better operating performance using the disc, which promoted the lowest specific consumption at the velocity of 4.7 km h -1 .Desempenho de semeadora-adubadora em função da velocidade de deslocamento e do mecanismo sulcador de fertilizantes R E S U M O Diariamente, o agronegócio aumenta a exigência por maquinário com melhor eficiência buscando a redução dos custos operacionais e a melhoria da qualidade do processo de semeadura. O objetivo do trabalho foi avaliar a qualidade da distribuição longitudinal de sementes e o desempenho operacional de uma semeadora-adubadora em função da velocidade de deslocamento e do mecanismo sulcador de fertilizantes. O trabalho foi realizado na área experimental do Departamento de Engenharia Agrícola da Universidade Federal do Ceará. O delineamento experimental foi em blocos casualizados, em esquema fatorial 2 x 3 com 4 repetições e dois mecanismos para depósito de fertilizantes (disco duplo desencontrado e haste sulcadora) além de três velocidades de deslocamento (4,7; 6,3 e 8,2 km h -1 ). Os resultados demonstram que para qualidade da distribuição de sementes o melhor desempenho foi com o uso da haste sulcadora na velocidade de 6,3 km h -1 . O conjunto trator-semeadora obteve melhor desempenho operacional com o uso do disco obtendo menor consumo específico na velocidade de 4,7 km h -1 .

“…The displacement velocity of the tractor-seeder set is a relevant factor in the sowing operation, since it influences aspects such as: fuel consumption (Palma et al, 2010), sowing quality (Melo et al, 2013) and operational capacity (Silveira et al, 2012).…”

“…4a). The double-disc showed a shallower working depth, as reported by Palma et al (2010) considering that they are bigger, and it is more difficult for them to penetrate the soil, as stressed by Seidi (2012). Similar results were also found by Koakoski et al (2007) and Mion et al (2009); according to the authors, such results are related to the fact that the hoe furrow opener reaches a greater depth due to the action of the tip, which causes a downward vector that tends to suck down the tip of the hoe.…”

“…Modolo et al (2012) also confirmed that the hoe causes more soil disturbance than the double-discs, and found values of 0.0045 m² for the former and 0.0037 m² for the latter. Moreover, Casão Júnior et al (2000) found that the hoe reduces plant residue on the furrows, although this effect may also be associated with speed, which is also reflected in other types of furrow openers, as explained by Celik & Altikat (2012).…”

The present study evaluated the effect of different associations between coulters and fertilizer furrow openers on soil disturbance, furrow depth and width, according to forward speed. The study was conducted on a farm in Santa Maria (Brazil/RS), in soil classified as sandy loam Ultisol. The experiment consisted of 24 combinations of treatments with three replications in a 2×3×4 factorial experiment. The combinations were formed by the interaction of the factors including: two types of furrow openers (hoe and double-disc), three types of coulters (no-coulter, smooth and offset fluted) and four levels of forward speed (1.11, 1.67, 2.22 and 2.78 m/s). Soil elevation and soil disturbance area profiles were obtained with the use of a micro profilometer, and disturbance values were calculated with the aid of computer software program Auto Cad. The disturbance area was not affected by speed; it was greater when using the hoe opener, and in association with the offset fluted coulter. Speed was inversely proportional to the depth of the furrows made by the hoe opener. Furthermore, the hoe caused the greatest furrow width (0.26 m) in comparison with the double-disc (0.24 m). The use of different coulters associated with furrow openers increased this variable (0.23 m for the no-coulter condition, 0.25 m with smooth and 0.26 m with offset fluted). The use of coulters combined with furrow openers reduces soil swelling, in approximately 8% for the smooth and 20% for the offset fluted.

“…According to Palma et al (2010), it is possible to use chisel furrowers for soil decompaction in addition to the cultivation of cover crops with a tap root system. The chisel furrowers form deeper seed furrows than the double disc furrowers.…”

Seeding quality and soybean yields from using different furrowers and operation speeds

et al. 2012

View full text Add to dashboard Cite

The sowing process for annual no-till crops affects the physical soil conditions around the seeds by exposing them to adverse conditions that may limit initial plant development and reduce potential yield. The use of seed drills that are not compatible with field conditions and the use of inappropriate seed drill speeds affect sowing performance. Therefore, this study aims to evaluate the effect of different seed drill types and operating speeds on soybean quality parameters and yield components. Two furrow opener (double disc and chisel) and four operating speed (0.86; 1.22; 1.47 and 1.94 m s -1 ) treatments were used. The following variables were evaluated: mean number of days until emergence, plant distribution uniformity, sowing depth, area of the soil disturbed, crop stand and grain yield. Overall, the chisel furrow opener provided a greater sowing depth and increased the disturbed soil area more than the double disc furrow opener. Increased operating speeds reduced crop stands and yields and increased the disturbed soil area. Key words: No-tillage, sowing performance, no-tillage quality ResumoEm culturas anuais submetidas ao sistema plantio direto o processo de semeadura afeta o condicionamento físico do solo ao redor das sementes expondo as mesmas a condições adversas, podendo limitar o desenvolvimento inicial das plantas e minimizar o potencial produtivo. O uso de sulcadores não condizentes com a situação de campo e de velocidades inadequadas são fatores que afetam o bom desempenho da semeadura. Nesse contexto, este trabalho teve por objetivo, avaliar o efeito de diferentes sulcadores e velocidades de operação sobre parâmetros de qualidade de semeadura e componentes de produtividade da cultura da soja. Os tratamentos foram compostos pela combinação entre dois sulcadores (disco e haste) e quatro velocidades de operação (0,86; 1,22; 1,47 e 1,94 m s -1 ). Foram avaliados: o número médio de dias para a emergência, a uniformidade de distribuição de plantas, a profundidade de semeadura, a área de solo mobilizado, o estande de plantas e a produtividade de grãos. De acordo com os resultados, o sulcador tipo haste proporcionou maior profundidade de semeadura e área de solo mobilizada, quando comparado ao disco duplo defasado. O aumento da velocidade reduziu o estande de plantas e a produtividade da cultura e aumentou a área de solo mobilizada. Palavras-chave: Semeadura direta, desempenho de semeadura, plantio direto com qualidade
