Two field experiments were carried out in salt clay soil to investigate the effect of harvest date after 180 and 200 days and foliar application of micronutrients as follows : control , Mn at concentration 0.5gm/Litre, 1.0 gm/Litre Zn at concentration 1.0gm/Litre,1.5 gm/Litre Fe at concentration 1.0gm/Litre ,2gm/ Liter on, Yield and Quality of sugar beet cv.Sultany. The obtained results are summarized as follows : Delaying harvest date up to 200 days significantly increased root diameter by 9.09 and 2.62% , root fresh weight by13.65 and 9.38, TSS% by 5.06 and 4.26 % in both seasons, root length by 24.97%, sucrose% by 11.92% Purity% by 7.25%, top yield by 15.52% root yield by 13.76 % , sugar yield by25.39 % in the second season compared by harvest at 180 days from sowing . The foliar application of Fe at 2g/L gave the highest values of root diameter11.10 and 11.47 cm, root fresh weight 871.37 and 744.79 g in both seasons, root length 23.22 cm, in the second season , root yield 26.83 t/fed in the first season , sugar yield 4.79 t/fed in the second season Fe at 1.0g/L gave the maximum top yield 14.97 t/fed in first season, Zn at 1.5g/L resulted the maximum sucrose% 17.98% in the second season.There is significant effect due to the interaction between harvest date and treated of micronutrients elements on root length,root fresh weight TSS%, root and sugar yields The maximum root length 23.22 cm, root fresh weight 894.03g, T.S.S% 22.43%, root yield 21.39 t/fed , sugar yield 4.92 t/fed were obtained from the interaction between the harvest date of 200 days from sowing and treated of Fe at 2g/L.,There is insignifican effect due to the interaction of harvest date and treated of micronutrients elements on root diameter, sucrose percentage, purity percetage in both seasons.
