Type: article
Abstract: Two field experiments were carried out at the Research Experimental Farmof Sabahia Agricultural Research Station in Alexandria during the two successive growingseasons of 2011/ 12 and 2012/ 13. BTS 303 genotype sugarbeet was cultivated to investigatethe effect of three sowing dates (15 Sept., 15 Oct.,and 15 Nov.); three plant spacing betweenhills (15, 25 and 35 cm.).and three nitrogen levels ( 60, 90 and 120 kg N / Fed. as ammoniumnitrate 33.5%N ) which were added on two equal doses before 1st, and 2nd, irrigation onsugarbeet yield and Quality. The result indicated that:Root ,fresh top , sugar yield T.S.S.% , sucrose % and purity% were superior due to 25 cmbetween hills. In both seasons, root and sugar yield were significantly decreased by planting inthe date on15 Oct.. Root, fresh top ,sugar yield ,T.S.S.% and sucrose % of sugarbeet root weresignificantly increased by increasing nitrogen levels from 60 up to 90 N kg / fed. There were asignificant interaction of sowing dates and distances between hills with regard to rootyield(t./fed) and purity % in both seasons, while on T.S.S.% and sucrose % in the first season.Statistically significant effect of sowing dates, plant spacing between hills and nitrogenfertilizers levels, on root yield (t./fed) and purity % in both seasons and their combinedanalysis.Generally, as a conclusion and on the basis of the obtained results that planting BTS 303sugarbeet on (25 cm between hills) ,sowing on October and. 90 kg N/ fed at two equal dosesbefore 1st, and 2nd, irrigation produced the highest yield and quality under Alexandria conditions.
