Abstract

The crop producers who cannot buy a second planter due to its cost, have been seeking to take advantage of the planter with the roller-type metering device in dry bean sowing. While seemingly adequate for dry bean sowing, if the roller structural properties and operating parameters suitable for the seed dimensions are not used, it can cause an increase in the seed damage ratio. In this text, a mission was undertaken to determine the damaged seeds ratio caused by the roller-type metering device under the influence of the flute diameter and helical angle, ground speed, and seeding rate. Seed damage was measured by collecting and weighing seeds from each replication during seed flow. Flute diameter (18, 20, and 22 mm), helical angle (0, 10, and 20 o ), ground speed (1.0, 1.5, and 2.0 m s -1 ), and seeding rate (100, 150, and 200 kg ha -1 ) independent variables and seed damage rate were selected as the dependent variable, to measure seed damage level. According to the results, the ground speed definitely affects the seed damage rate, while the helical angle and flute diameter quite affected. The increase in the seeding rate, ground speed, helical angle, and flute diameter reduced the seed damage rate. The lowest seed damage rate values were obtained at 200 kg ha -1 seed rate, 2 m s -1 ground speed, 22 mm flute diameter, and 20 o helical angle.

Feasibility Analysis of Fluted Roller Dispenser Application for Precision Fertilization

“…A commercially available volumetric dispenser was selected (Fig 1 .), based on fluted roller design. Such a dispenser was considered due to its fairly simple construction, low price, versatility and longevity (Huang et al, 2018, Bangura et al, 2020, Kuş et al, 2021. In addition, such dispensers have proven themselves to be accurate enough in the grain seed sowing applications (Kuş et al, 2021).…”

The roller is divided into grooves, with volume dependent on the radius of the flute and length of the roller.…”

“…In the study, a straight fluted roller (Fig 2 .) was selected with 10 grooves, each of them with volume of 2.048 cm 3 . With altering roller parameters such as flute diameter, shape, length and angle, the discharge rate is affected (Liping et al, 2018, Kuş et al, 2021. Using an optimal roller that ensures uniform discharge can result in saving up to 40% from fertilizer costs (Bangura et al, 2020).…”

“…Table 1 Properties of blueberry fertilizers in scope Kuş et al, 2021) in this study a different approach has been selected due to spot application. The number of discharged grooves is controlled by the feedback from the encoder attached to the fluted roller.…”

“…More suitable is a spreader based on roller with outer grooves, often referred as a fluted roller dispenser, which has gained significant popularity and is considered very efficient when cultivating in rows (Lv et al, 2012). Such dispensers are simple, easy to manufacture, lightweight and compact (Kuş et al, 2021), capable of providing discharge uniformity usually between 10% and 20%, where better than 20% is considered acceptable and better than 10% is considered good (Huang et al 2018). Due to the plantation pattern on the blueberry field, there are bare spots (Soots et al 2021) between plants.…”
