The aim of this study was comparing between three potato cultivars: "Afamia,
Loulou and Tadmur" which are planted in two different times (spring time and autumn
time), for the plant old age and some yield properties and some quality properties. Aft
er
ripping and harvesting, result showed superior Loulou to Afamia and Tadmur in most
parameters at the two planting times, so the productivity of Loulou was more than Afamia
by 6 ton/h in the spring and 1.6 ton/h in the autumn. For the starch and dry matter content,
Loulou tubers in the two planting times contained more amount than the other cultivars,
and more than the global average (%14 starch, %22 dry matter).
