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.
