Potato planter performance and effects of non-uniform spacing

Effect of Cup Size, Seed Characteristics and Angular Speed on the Performance of an Automatic Potato Planter under Laboratory Conditions

“…Research results of Misener (1979), Altuntas (2005) and Al-Gaadi & Marey (2011) agree with these results. However, Buitenwerf et al (2006) and Sieczka et al (1986) stated that as the speed increased, the accuracy of seed spacing became better. Al-Gaadi & Marey (2011) determined that the values of CV% were 28.73, 37.10, and 54.53% for the ground speeds of 1.80, 2.25, and 3.00 km h -1 , respectively.…”

“…Al-Gaadi & Marey (2011) determined that the values of CV% were 28.73, 37.10, and 54.53% for the ground speeds of 1.80, 2.25, and 3.00 km h -1 , respectively. Entz & LaCroix (1984), Sieczka et al (1986) and Misener (1982) stated that the coefficient of variation of seed spacing obtained from different potato planters ranged from 20% to 80%. Misener (1979) stated that the values of CV% for the pick type potato planter ranged from 55.3 to 68.7% while the values of CV% for the cup type potato planter ranged from 59.2 to 87.1%.…”

“…Similarly, Al-Gaadi & Marey (2011) determined that the lowest and the highest mean values of CV% were 28.73 and 54.53% for ground speed of 1.80 and 3 km h -1 , respectively. Sieczka et al (1986) stated that high planting speeds reduced performance of potato planter. Buitenwerf et al (2006) determined that potato shape had an important effect on seed spacing uniformity.…”
