Morocco is among the major olive-growing countries around the Mediterranean, its
productivity increases from one year to the next, especially after the introduction of the Green
Morocco plan, which aims for an increase in the olive-growing area by the year 2020. The
increase in productivity especially in olive oil is strictly accompanied by an increase in waste
generated after crushing. The objective of this study is to value the olive pomace compost from
traditional system as a soil amendment, and study its effect on the cultivation of herbaceous
plants. The germination test is carried out in small pots, placed in a sunny place in a laboratory.
25 Fenugreek seeds were germinated in each pot which contains soil and a well-defined
percentage of compost (5%, 10%, 15%, 20% and 25%). The seeds were irrigated regularly twice
a week. All the tested seeds in different percentages of compost germinated at a rate of more than
90%. The final germination rate for the different concentrations was significantly important from
the control (the pot that contains only soil). However, the 5% compost concentration allows an
optimal germination rate. As well as the vigour of the seedlings that approves the positive effect
of using olive pomace compost with a significantly high vigour index for all compost percentages
(5%, 10%, 15%, 20% and 25%). The olive pomace compost use also improved the dry matter
weight of the fenugreek seedlings for all percentages
