| Abstract | ||
| In the 2020/2021 and 2021/2022 seasons, this study was performed in the Nubaria region, Fifth Section, El-Beheira Governorate, Egypt (latitude 30° 53' N and longitude 30° 04' E) to assess performance of three multi-germ varieties and their response to different levels of liquid bio-nitrogen fertilizer (EM) and inorganic nitrogen on growth, yield, and quality of Sugar beet (Beta vulgaris var. saccharifera) in sandy clay loamy soil properties. Eighteen treatments included three sugar beet cultivars (Pleno, Nader, and Bts 970), three inorganic nitrogen levels (60, 90, and 120 kg N /fed) and two effective microorganism levels in soil (without addition and 6 L /fed). Split-split plot distribution with three replications were employed for a randomized complete block design. Over the two seasons, the Bts 970 variety recorded the highest root diameter (RD), fresh weight (FW), leaf area index (LAI), potassium content, sucrose and extracted sugar percentages, as well as root and sugar yields/fed, while simultaneously demonstrating the lowest sodium and alpha-amino N content. In both seasons, soil treated with effective microorganisms recorded the highest root diameter (RD), fresh weight (FW), leaf area index (LAI), potassium and alpha-amino nitrogen contents, sucrose and sugar lost to molasses percentages (SLM %) and sugar beet root and sugar yields/fed. An increase in extracted sugar values was noted in the second season. However, sodium content significantly decreased, in both seasons. Planting variety Bts 970 in soil treated with EM and fertilizing N with 120 kg/fed can be recommended to give the highest root and sugar yields under Nubaria conditions | ||
