Use of palm (Poenix dactilyfera L.) fiber and sewage sludge co compost as substrates in soilless crop system.

The Co-Compostage (CC) of Palm (Poenix dactylifera L.) Fiber (PF) and Sewage Sludge (SS) at volume rate (1PF/1SS), mixed with Top Soil (TS) have been used as a substrate for cucumber cultivated in soilless crop system. Five substrates with volume ratio T (CC-TS) were tested: T (10-0), T (9-1), T (8-2), T (7-3) and T (6-4).
