Abstract
A field experiment was conducted during summer season of 2008 in Sakha Agricultural Research Station Farm; Kafr El-Sheikh Governorate. This study aimed to clarify the effect of different irrigation systems and potassium and phosphorus fertilization levels on maize crop. The obtained results can be summarized in; - Irrigation systems and fertilization levels interaction significantly affect maize grain yield. The highest value of maize grain yield (2.14 ton/fed) was recorded under furrow irrigation system + 125% of P and K recommended dose treatment. - Increasing P and K fertilizations levels from 50 to 125% of the recommended dose caused an increase in maize stalks yield amounted by 45.11%. The highest mean of maize stalks yield (5.250 ton/fed) was recorded under furrow irrigation system + 125% of P and K recommended dose. - Furrow irrigation improved maize grain potassium utilization by 24.43% than that of sprinkler irrigation. Potassium uptake by maize grain of furrow irrigation system + 125% of P and K recommended dose treatment was higher than that of sprinkler irrigation system + 50% of P and K recommended dose treatment by 94.53%. - Furrow irrigation system recorded the highest value of phosphorus uptake by maize grain (8.033 kg/fed) compared with other irrigation systems. 125% of P and K recommended dose recorded the highest value of P uptake by maize grain (9.53 kg/fed) compared with the other fertilization treatments. - Furrow irrigation system decreased maize water use efficiency by 35.37 and 63.30% less than that of drip and sprinkler irrigation systems, respectively. The highest value (1.64 kg grain / m3) of water use efficiency for maize was recorded under drip irrigation system + 125% of P and K recommended dose.
