| Field experiment was conducted at the f arm of S akha Agric. Res. S talion during the two successive seasons (2001 and 2002). This investigation aimed to study the effect and residual effect of treated sewage sludge (air-dried) (TSS) and farmyard manure (FYM) application on some soils physical and chemical properties and its productivity 0 f maize and sugar beet crops. Split plot design with 4 replicates was implemented. Application rate occupied the main plots. Five rates: 0, 10, 15, 20 and 30 tons/fed were added one lime at the beginning of the experiment while TSS and FYM were applied to the sub-plots. Results could be summarized as follows: Application of ar.y of TSS or FYM had slightly decreased the soil pH, while EC, soluble Na, Ca, Mg and SAR were obviously increased. Microelements (Cu, Zn and Mn) were slightly increased. Meanwhile, the mean concentration of Fe was obviously increased. It is noticed that FYM increased EC, SAR values and Cu content more than TSS especially at the low rates of application, while the inverse direction was noticed for Zn, Fe and Mn. Application of any of TSS or FYM had slightly decreased aggregation index (AI). While mean weight diameter (MWD), optimum size, bulk density (BD), hydraulic conductivity and total porosity were slightly increased at the low rates of TSS (10 - 15 tons/fed.) and then declined. It is found that FYM surpassed TSS in its effect on the physical properties in the surface layer, while the inverse direction was induced (i. e, TSS surpassed FYM) in the subsurface layer. The residual ef1ect of both TSS and FYM after sugarbeet was improving the studied chemical and physical properties. Grain yield of maize was increased at the low rate (10 tons/fed.) and then gradually decreased with increasing the rate of either TSS or FYM. But TSS surpassed FYM in reducing maize grain Root weight of suqarbeet yield, sugar percentage (%) and total sugar content were increased as a result of the residual effect for increasing TSS and FYM application rates.
