A study was carried out at the Experimental Farm of the Faculty of Environmental Agricultural Sciences, Suez Canal University in El-Arish, during two successive seasons, 2004/2005 and 2005/2006. The experiment aimed to study the effect of irrigation intervals and distances between drip irrigation laterals on fodder beet (Beta vulgaris L. cv. VÖrÖshenger). The experiment was assigned for cultivating fodder beet plants. The experiment included 9 treatments for the interaction between 3, 5 and 7 days irrigation intervals and 40, 50 and 60 cm distances between drip lateral lines. Each treatment plot consisted of 3 lateral lines, each was 10 m long. The treatments plot area was either 12, 15 or 18 m². Seeds of fodder beet plants were sown on the 1^st of October in 2 successive seasons, 2004/2005 and 2005/2006, at a rate of 3 kg.fed^-1. Actual evapotranspiration and fresh and dry yield of roots and top weights increased with decreasing irrigation intervals. However, they increased with increasing the distance between irrigation lines in both seasons. The water use efficiency increased with increasing irrigation intervals, while it was decreased with increasing the distance between irrigation lines. Treatment 3 days irrigation interval had the highest values of root and top content of crude protein, but it gave the lowest value of crude fiber and total ash content in both seasons. Treatment 7 days irrigation interval had the lowest root and top content of crude protein but it gave the highest crude fiber and total ash content in both seasons.  The highest value of actual evapotranspiration was obtained at 3 days irrigation intervals with 60 cm distance between irrigation lines. The irrigation every 3 days with 60 cm distance between irrigation lines gave the highest yield, while the irrigation every 7 days with 40 cm distance between irrigation lines gave the highest water use efficiency.
