The statistical analysis results showed out that there was a significant variation between the studied collecting times (harvesting dates). and the (fruit formation) stage was the best significantly for the biomass trait (725 Kg.h-1) then the (Maturity) stage (570.8 Kg.h-1) . while the (green grow) stage was the best significantly for the oil percentage trait (4.1%), then the (flowering) stage (3.73%) . so that it is clear, form this studying, the importance of harvesting date on the economic yield of AL khalili thyme.
