| Abstract | ||||
| The objective of this research was to develop a single-row of automatic potato planter by modification the metering mechanism spoon size to well-matched with size and shape of slide tuber that previous cutting to overcome the high prices of import potato tuber in January period. This planter was locally fabricated to be operated by mini tractor to suit the small holdings. The modified planter performance was evaluated under three different spoon diameters of 25, 35 and 45 mm, three forward speeds of 1.6, 2.4 and 3.2 km/h and two different shapes of potato (oblong and spherical) namely, Sponta and Diamond varieties. The field results revealed that, as spoon size diameters (D) increased from 25 to 45 mm, the percent of void tubers decreased from 4.04 to 2.58% and the percent of double tubers increased from 2.83 to 8.31 %. While as the forward speed (S) increased from 1.6 to 3.2 km/h, the percent of void tubers increased from 2.57 to 3.87 % and the percent of double tubers decreased from 7.18 to 4.95 %. The proper distribution uniformity values of 91.81% for the potato planter was obtained at 25 mm spoon diameter and 3.2 km/h forward speed which gave 3.4 and 4.79 % for the percent of void and double tubers respectively. The distribution uniformity of oblong potato tubers (Sponta) was better than that of spherical potato tubers (Diamond). At the proper operating parameters, the consumed specific energy was 22.28 kWh/fed, the estimated total costs was 180.18 EGP/fed. | ||||
