A Field experiment was conducted on a sandy loam soil in Wadi Sudr South Sinai, Egypt to study the effect of a mixture of PW and FYM, using a combination (0 +0, 50 +0, 37.5 +12.5, 25 +25, 12.5 +37.5 and 0 +50 Mg ha-1) for mixture FYM and PW, respectively, with two levels of SRM (0 and 7 L ha-1) to reflect some of the calcareous soil properties below saline irrigation and to improve the yield of sunflower. The data obtained showed that soil BD, PR, HC, pH and EC decreased with increasing application rates of PW using two rates of SRM, while the MWHC and OC were increased. The data obtained showed that sunflower seeds yield increased with increasing application rates of PW using two rates of SRM. The average increases of sunflower seeds yield were 23.21, 27.68, 44.64, 59.82 and 75.00 % relative to the control, (0 FYM + 0 PW) Mg ha-1 with the application mix of FYM and PW without SRM on the same mixes, respectively. While they achieved 29.82, 39.47, 55.26, 73.68 and 90.35% respectively for blends of FYM and PW with SRM additions on the same blend. High significance was found between sunflower seed yield altered by FYM and PW mixing and either pH, EC, OC, BD, PR, HC or MWHC, respectively. So, we can say that the application mix of FYM+PW is considered effective in improving calcareous soil properties and productivity, which reduces environmental pollution from these wastes.
