Sowing occurs in agricultural areas with irregular relief, influencing the quality of seed and fertilizer distribution. The aim of this study was to analyze the performance of different fertilizer metering mechanisms of planters as a function of longitudinal inclination. The experimental design was a completely randomized design with five treatments and six replications. Treatments consisted of five longitudinal inclinations to the metering mechanism (−10, −5, 0, 5, and 10 degrees). The mass of fertilizer collected per minute was considered as a replication. We worked with two types of fertilizers: a mixture of granules and powder. Metering mechanisms used were a horizontal toothed rotor, helical without flow restrictor, helical with lateral overflow, and helical with longitudinal overflow. The longitudinal inclination of ±10° in relation to the leveling altered the metered amount of both fertilizers used in all metering mechanisms. The helical with lateral overflow was the metering mechanism that obtained the smallest amount variation of fertilizer distributed in the different longitudinal inclinations, followed by the helical with longitudinal overflow, horizontal toothed rotor, and helical without flow restrictor.

“…The achievement of the set seed spacing majorly depends on the machine's technical variables such as the type of seed pickup mechanism, the machine operating speed, overall gear ratio between drive wheel and seed rotor, and to some extent on seed quality. Although, there are many planters having different seed metering mechanisms, the application of single seed metered plate mechanisms (horizontal, vertical and inclined plate) has increased rapidly due to better seeding performance than that of other mechanical rotors [2] However, in recent times due to climate variability and lack of sufficient moisture in the soil for reasonably sufficient time in the sowing window period, farmers prefer to operate the planters at higher speeds to complete the sowing operation of various rain fed crops within a short period. Thus, the metering mechanism should be accurate enough to plant seeds at the required seed to seed distance in a row.…”

Aims: The present study was conducted to determine the “Effect of Different Operating Parameters on Seed Holding in the Single Seed Metering Unit”. Study Design: An attempt was made to development seed metering unit and evaluated for its performance with battery drive i.e. seed rate, seed holding ratio, single seed holding ratio, double seed holding ratio and missing index. The shapes of cells speed of seed plate and number of cells on seed plate were chosen as parameters. A factorial completely randomised design used for analysis of variance. Results: At the end of the research, it was found that the cell’s shape, peripheral velocity and number of cells on seed plate had an effect on the seed holding ratio (SHR) at a significant level of 5% (P<0.05). The diameter and thickness of the seed metering plates were 100 and 8 mm respectively. The hopper was of the trapezoidal section with height of 12.5 cm , volume 3510 cm3 and thickness of material of 2.5 mm. For maize seed variety: Tulasi Naga If the velocity of seed plate increases then seed holding ratio decreases, seed holding ratio also decreased with increase in number of cells on seed plate. Oblong shape with extension was suitable for these seeds. For maize seed variety: Goodrej Ultra when the velocity of seed plate increased then seed holding ratio decreased, seed holding ratio also decreased with increase in number of cells on seed plate. Oblong shape was suitable for these seeds. For maize seed variety: Laxmi 2277 seed holding ratio increased with increase in velocity of seed plate, seed holding ratio also increased with increase in number of cells on seed plate. Oblong shape was suitable for these seeds. Conclusion: The highest and least value of seed holding ratio is 94% at a speed of 30 rpm in shape 2(6 and 7 cells) and 31% at a speed of 30 rpm in shape 1(7 cells), 39% at a speed of 26 rpm in shape 2(6 cells) and 12% at a speed of 30 rpm in shape 1(7 cells), 45% at a speed of 26 rpm in shape 1(6 cells) and 6%at a speed of 30 rpm in shape 2(7 cells) for laxmi, goodrej and tulasi variety of seeds respectively.

“…In the precision sowing the feeder mechanism of the seeder has as function the regular dosage of the seeds within the seeding line, with pre-defined spacings (Jasper et al, 2011;Mao et al, 2015;Weirich Neto et al, 2012). Silva & Gamero (2010) state that speed is one of the main factors that interferes with the quality and operational performance during sowing.…”

ABSTRACT:The aim of this study was evaluate the longitudinal distribution of maize seeds using a seeding line prototype, whit a microcontroller data acquisition system, at different speeds and types of horizontal feeder discs. Initially it was constructed a prototype simulator of seeding line, in the laboratory, and mounted two systems of microcontroller data acquisitions with infrared sensors for maize seeds counting. A test was conducted in a completely randomized design in split plots with factorial scheme of treatments 5 x 2 x 2, being the parcel two types of microcontroller data acquisition systems (infrared sensors in parallel and an diffuse infrared sensor), the factors were two feeder discs of maize seeds (inclined and normal) and five sowing speeds (3.0, 4.0, 5.0, 6.0, and 8.0 km h -1 ), with three replications, totaling 60 plots. The results showed that the data acquisition systems presented efficiency higher than 93% in the perception of the seeds. The lower speeds provided a seed distribution closer to the desired. The spacing average error between seed with the microcontroller data acquisition system with diffuse sensor was 0.0206 meters and the system with infrared sensors in parallel was 0.0158 meters.
