This field experiment, was conducted to investigate a comparison of two
methods for harvesting potatoes: mechanical and handy when using moldboard and chisel
plow for primary tillage and three different distances for planting tubers in the rows 15, 25,
and 35 cm in silt clay loam soil south of Baghdad. The factorial experiment followed a
randomized complete block design with three replications using L.S.D. 5 % and 1 %.
Mechanical harvest recorded the best valid potato tubers at 88.78 %, marketable yield of
31.74 ton. ha-1, efficiency lifted 95.68 %, tubers damage index 28.41, speeding up the
harvesting process and reducing time and effort. Handy harvest gave the least damage to
potato tubers, 6.02 %, and unlifted potato tubers, 4.32 %. Howe
