Two field experiments were carried out at the Agricultural Experiments Desert Station, Faculty of Agriculture, Cairo University in Wadi El-Natroon, El-Beheira Governorate, during 2008/2009 and 2009/2010 seasons, to study the response of three sugar beet varieties, i.e. KWF1436, Swello and Faraha to compost (CM) and Mineral-N fertilizer and their combinations, at five treatments : 4 tons fed⁻¹ of (CM), 4 tons fed⁻¹ of (CM) +80 kg N fed⁻¹ (100% N), 4 tons fed⁻¹ of (CM) +60 kg N fed⁻¹ (75 % N), 4 tons fed⁻¹ of (CM) + 40 kg N fed⁻¹ (50 %N) and 80 kg N fed⁻¹(100 % N) on growth attributes of sugar beet under drip irrigation system. The obtained results revealed that the tested sugar beet varieties significantly differed in all the traits under study except for, top dry weight in the 1st season and root diameter in the 2nd one. KWS1436 variety was superior to the other two varieties in chlorophyll a and b in both seasons.
