Abstract
Two field trials were conducted in 2016/2017 and 2017/2018 seasons at Mallawy Agric. Res., Station, (latitude of 28O N, longitude of 30O E and altitude of 49 m above sea level), El-Minia Governorate, Egypt, to study the effect of two harvest ages (180 and 210 days after sowing), on yield and quality of eight sugar beet varieties (Steel, Pyramide, Kosmas, Lammia, Belino, Amelie, Drena, and Beta 398). A randomized complete block design (RCBD) was used, in a split plot arrangement and replicated three times. The main-plots were devoted for harvest ages, while the evaluated sugar beet varieties were randomly sown in the sub plots, in both seasons. The results revealed that: 1. Harvest age exhibited a significant effect on all studied traits in both seasons. Beets harvested at older age (210 days after sowing) surpassed those harvested earlier (180 days after sowing) in all traits in both seasons, except loss in sugar yield/fed and α-amino- N%. 2. The tested sugar beet varieties varied significantly in all studied traits in both seasons.  Beta 398variety recorded the best values of root, top, and sugar yields/ fed, in both seasons. The best values of sucrose %, loss in sugar/fed and sugar recovery % were obtained by Drena variety in both seasons. Lammia variety recorded the highest values of α-amino-N %, while the highest value of alkalinity coefficient was obtained by Kosmas variety, in both seasons. Planting Beta 398 sugar beet variety and harvesting it after180 or 210 days from sowing could be concluded get the highest productivity and quality of sugar beet under conditions of Minia Governorate.
