| Abstract | ||||
| A field experiment was conducted at the Experimental Farm of Nunaria Agric. Res. Station, Egypt, during two successive growing seasons on a calcareous sandy clay loam soil to study the direct effect of compost, sulphur and phosphorus on yields of faba bean and their residual effect on succeeding maize crop as well as soil physical and chemical properties. Two kinds of composts (compost A&B) both at two levels (0 and 4 ton/fed) were applied in combination with two levels of sulphur (0 & 200 kg S Ifed) and lor two levels of phosphorus (0 & 13.5 kg P/fed). Application of compost .in combination with S or P resulted in a significant increase in seed yield of faba bean compared with the control (Co + So + Po) treatment or that received compost A or B alone. A further insignificant (P>0.05) increase was occurred as a result of application of Sand P with the compost. Maize grain yield, as an indicator of the residual effect, showed a similar trend. A small but consistent improvement in soil properties (pH, Organic carbon, total-N and saturation percent) and a noticeable increase in available nutrient (P, Fe, Mn and Zn) contents of the soil were detected as a result of the applied materials .. Maize grain yield was positively to correlated with OC (P<0.05), total-N (P<0.01), available P(P<0.01) ,available Zn(P<0.05) and inversely related to soil pH (P<0.10). Generally, the best treatment to improve and sustain calcareous soil properties as well as increasing productivity of faba bean and maize yields was the combined treatment of compost A or B each at 4 ton + 200 kg S + 13.5 kg P per feddan. | ||||
