Two field experiments were conducted at the village (7) in Gelbana, North Sinai Governorate, Egypt during two successive winter seasons of 2013/2014 and 2014/2015 to study the response of sugar beet (Mirodor) grown on saline sandy loam soil to study the interaction effect of compost, (CO) amendment and foliar spraying with micronutrients (Zn and B) solely or in combinations on some growth parameters, productivity and nutrients content in sugar beet roots. The obtained results reveal that CO and foliar application with Zn and B enhanced the growth and yield productivity of sugar beet roots as well as nutrient contents. Available N, P, K, Fe, Mn, Zn and B contents were increased due to the above mentioned treatments. On the other hand, the electrical conductivity (EC dSm^-1) and soil pH values decreased due to these treatments. Foliar spray with micronutrients in combination with CO substantially elevated these parameters N, P, K, Fe, Mn, Zn and B contents in roots were significantly increased by application of the treatments. The highest response of productivity and nutrients content in root were achieved by application of CO in combination with foliar spray of Zn + B followed by foliar spray of Zn + B in both seasons . Highest values of yield, yield components, nutrient contents and sucrose percent as well as sugar yield were obtained due to the application of compost at rate of 5 Mg fed.^-1 + foliar spray with Zn + B in both seasons.
