<br/><br/> Two field experiments were carried out at Sakha Research Station, Kafr ElSheikh Governorate during two growing seasons of 2010/2011 and 2011/2012 to study the effect of the combinations between foliar application of three Fe levels (0,1 , and 2g/l as Fe- EDTA), three Mn levels (0, 0.5 and 1 g/L as Mn-EDTA) and two sulpher levels (0 and 8 cm S/L as calcium poly sulphide 30 %) on yield and quality of sugar beet. The obtained results proved that: • The increase of Fe level up to 2 g /L, Mn up to 1g/L and 8 cm S/L individually as foliar application significantly increased root length and diameter as well as sucrose%, extractable sugar %, purity % , yields of top, root and sugar (ton / fed), whereas Juice impurities content (K, Na and ?-amino N) and sugar losses to molasses were decreased in both seasons. • Foliar spray beet plants at the rate of 2g Fe/L+1g Mn / L+8 cm S/L achieved the highest root yield (29.32 and 33.82) in the 1st and 2nd seasons, respectively. Therefore, it could be recommended that, spraying beet plants by 2g Fe/L +1g Mn / L+ 8 cm S/L as foliar application to maximize root yield.
