The compost from some agricultural and industrial wastes was prepared by aerobic composting. All types of compost were tested for germination and growth of cucumber and tomato seeds in the treatments of 1) final product of compost, 2) compost mixed with vermiculite 1:1 (v/v)1 3) compost mixed with vermicuhte 1:3 (viv), 4) compost washed with water at 1:10 ratio and 5) compost completely washed with water. The imported peat moss was used as a control. The reuÍts of germinaton show that, the germination percentage of cucumber and tomato seeds sown in different types of compost viithout mixing with vermiculite or washed with water were very low compared with peat moss. This result was related to the highly electrical conductivity of the final product of compost. Reducing the EC values by mixing the compost with vermiculite at 1:1 and 1:3 ratios gave some advances. Although the germination percentage was improved by increasing the mixing ratio with vermiculite, the media becomes smoother and find a difficulty for seedlings transport. The germination percentage of cucumber and tomato seeds was improved when they sown in compost washed with water at 1:10 ratio as well as completely washing with water. The growth of both seedlings of cucumber and tomato was better in compost completely washed than those grown in compost washed with measured volume. The results also show the sugar cane bagasse foflowed by banana andlor rice straw compost may be used a seed-bed like matena( in Egyptian agriculture. More studies will be needed on these materials to establish the production of growing media to substitute the imported peat moss.
