Two field trials were conducted out in 2009/2010 and 2010/2011 seasons at Kom Osheim, El-Fayoum Governorate to study the effect of three sowing dates (1^st October; 15^th October and 1^st November) and soil application of sulphur fertilizer in the form of Calcium poly sulfide CaSO₄ (30% sulphur) at the levels of (zero, 125 and 250 kg CaSO₄/fed, mixed with soil) which were applied at 45 and 75 days age, on Kawemira variety. A split plot design with four replicates in both seasons was used. The main plots were assigned to sowing dates, whereas, soil application with CaSO₄ in the sub plots. The results indicated that: early sowing dates at 1^st October significantly increased root diameter, root fresh weight/plant, as well as, root and sugar yields/fed, while, mineral contents SO₄% and N% were significantly decreased as compared with the other two sowing dates 15^th October and 1^st November. While, sown sugar beet at 15^th October gave the highest sugar% in both seasons, respectively. Soil application with sulphur (CaSO₄) level up to 250 kg CaSO₄/fed significantly increased root diameter, root fresh weight/plant, sucrose% andyields/fed (root and sugar), while, minerals content of SO₄% and N% were increased as compared with control and sulphur (CaSO₄) level with 125 kg CaSO₄/fed in both seasons, respectively. The interaction between early sowing date at 1^st October and soil application with 250 kg CaSO₄/fed significantly increased sucrose%, root and sugar yields/fed in both seasons.
