| Abstract | ||||
| Two field experiments were conducted during 1996 and 1997 summer season at Sidi Salem area Kafr El-Sheikh governorate (salt affected soils) using corn variety third hybrid 310, to study the effects of two irrigation water quantity levels (F.C. and F.C. + 15%); potassium, zinc, potassium+zinc fertilization, control treatment and two nitrogen levels of 60 and 120 kg N./fed. Increasing irrigation water quantity from F.C. to F.C. + 15% increased N-fertilizer efficiency, where the values protein content (kg/fed) were increased by 6.23% and 7.69% in the first and second seasons with 60 kg N/fed. Increasing N-fertilization led to increasing actual water consumptive use by corn. Potassium and zinc fertilization increased corn water consumptive use. Soil moisture extracted from the surface layer with was higher all treatments. Increasing irrigation water quantity together zinc and potassium with fertilization led to increasing the amounts of water extracted from 30-60 cm layer and increased water use efficiency by corn. | ||||
