The experiment was carried out at the research stations of Salo in Deir-
Azzor agricultural research center and Tel Sandal in Idlib agricultural
research center. Land plots infected previously with sesame wilt disease,
Macrophomina phaseolina (Tas
si) Goid, and Fusarium oxysporum Schlecht
were cultivated for two growing seasons (2007 and 2008) with medicinal
species such as, Cumin (Cuminum-sativum), Black seed (Nigella sativa L.) and
Fenugreek (Trigonella foeniculum L.) and another infected plot was left blank
as a control plot. Zuri, a local sesame variety, was cultivated in all plots for two
growing seasons (2008 and 2009).
Results showed that the control plots had the highest percentage of infected
sesame plants compared to the lowest percentage found in those plots that had
been cultivatd previously with Black seed, Cumin, and Fenugreek. Plots
cultivated previously with Black seed gave the highest sesame yield and
followed by those plots of Cumin. The The average percentage of germination
of sesame, as a phenological growth indicator, was increased in those plots
planted before with Cumin and the average number of capsules per plant was
increased at both locations by 36.75 capsules after Black seed in comparison
with the control.
