The efficiency of SOP, FYM (farmyard manure) and wheat straw was studied on two maize varieties viz., EV-1098 and EV-3001 at Agronomic Research Farm of University of Arid Agriculture, Rawalpindi in 2003. All the organic and inorganic constituents were thoroughly mixed in the soil 15 days before sowing. The treatments comprised, control, FYM (3 t ha-1 ), wheat straw (3 t ha-1 ), SOP (60 kg ha-1 ), FYM + wheat straw (1.5 t each ha-1 ), FYM (1.5 t)+ SOP (30 kg ha-1 ), wheat straw (1.5 t)+ SOP (30 kg ha-1 ), FYM + wheat straw (1 teach) + SOP (20 kg ha-1 ). The statistical analysis of data for soil moisture content and leaf moisture content at three different stages showed significant differences among different manuring treatments. However, the highest soil moisture in both the varieties was observed in treatment having high doses of FYM followed by the FYM mixed with other fertilizers.
