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).
The field experiment was conducted Al Raqqa research station, the General
Commission for Scientific Agriculture Research (GCSAR),. during the
2011/2012- growng season to compare quality traits of four monogerm fodder
beet varieties, i.e. Jamon, Sp
lendids, Starmon and Vermon. The experiment
was run in Autumn during November and in Winter during January.
Experiment was carried out in accordance with the split plot design with three
replications. The results of the comparison test T-Test preference fodder beet
cultivation in the autumn compared with winter, but by a small percentage in
most of the quality traits. The results also showed that the monogerm variety
Vermon was the best in most of the quality traits as compared with the other
varieties, followed by Starmon. It was recomended to cultivate fodder beet in
both autumn and winter under Al Raqqa conditions, but after conducting a
complementary researches concerns the other agricultural treatments as, lifting
time, plant spacing, fertilization …etc, and to test more monogerm and
multigerm varieties from different sources.
