Abstract

The experiment was started at the spring of 2013 located in Giza governorate by installing an integrated aquaponic system for purification wastewater from fish pond and production of a forge crop. The effects of seeding quantity, water time duration on crop yield and pollutions reduction were studied in this study. The results indicated that Barley forge crop could be produced in 23days from germination to harvest. The treatment 2.5kg/ m² seed quantity with 5days water time of duration gaves the best result for vegetative yield (17.23kg / m²). Based on sixteen harvests per year, a total possible yield of 275.68 kg / m². This is more than 367.5 time greater than the yield obtainable from filed grown conventional forge of 0.75 kg / m². The pollution reduction range from 20-46.51% , 12.28-45.06% , 52.69-73.5% , 61.13-90.53% and 2.43-4.41 % can be achieved for the chemical oxygen demand (COD), total solids (TS), nitrate - nitrogen (NO₃^--N), phosphate – phosphorus(PO₄^3--P) and potassium oxide (K₂O), respectively.
