A field experiment was carried out during the 2019/2020 and 2020/2021 growing seasons to study the performance of two sugar beet varieties under three planting densities and three planting dates. Planting densities, planting dates and varieties as well as their interactions exhibited significant effects on all studied traits including, root length and diameter, root and top yields, sucrose content, impurities%, quality index (Qz), recoverable sugar (RS)%, and recoverable sugar yield (RSY). The highest root length and diameter from planting sugar beet at a density of 28,000 plants/feddan (Feddan = 4200 m2) in both growing seasons. Meanwhile, the highest values of the remaining studied traits were produced from cultivating sugar beet at 42,000 plants/ feddan Superiority in all studied traits was scored to the September 25th planting date. The variety Hercules surpassed the Husam variety in all the measured desirable traits in both growing seasons. Moreover, the variety Hercules produced the highest values of root and top yields, sucrose content, impurities%, quality index (Qz), recoverable sugar (RS)% and recoverable sugar yield (RSY) when planted at a planting density of 42,000 plants/ feddan on September 25th in both growing seasons.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80542455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The beet sugar industry in the tropical and subtropical regions, which are mostly developing countries is growing as an important component of sugar production. A field experiment was conducted at Delta Sugar Company Research Farm, ElHamool, Kafr ElSheikh, Egypt to evaluate the response of sugar beet varieties to interand intra-row distances. The analysis of variance (ANOVA) revealed significant effects of interand intra-row distances on all studied traits, i.e., sucrose content (Pol%), Na%, K%, α-amino-N%, quality index (Qz)%, root yield (RY), recoverable sugar (RS)%, recoverable sugar yield (RSY), sugar loss (SL)% and sugar loss yield (SLY) either in one or both growing seasons except for the effect of inter-row planting distances on Na% and loss sugar yield in both growing seasons. The results revealed that increasing the inter-row planting distance from 50 to 60 cm led to a significant reduction in sucrose content, Na%, RY, RS% and RSY. However, increasing the inter-row planting distance from 50 to 60 cm is associated with a significant reduction in the Qz%, RS%, SL% and SLY. Increasing the intra-row planting distances from 10 to 15 cm led to a significant reduction in sucrose%, Na%, Qz% and RS%. Additionally, significant variations in all studied traits were observed among varieties. The interactions between the studies factors and varieties exhibited significant effects on all studied traits. Planting the variety Garrot at 15 and 50 cm intraand inter-row distances produced the highest Qz%, RY and RSY. The lowest SLY resulted from planting the sugar beet variety Husam at 10 and 60 cm intraand inter-row planting distances. The results of the present study of great importance for a sustainable production of sugar beet in Egypt.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85028508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the cellulolytic activity and citric acid production by the active producers were assayed on a carboxy methylcellulose medium. The study was extended to improve citric acid production from sugarcane bagasse using mixed cultures of the highest endo-cellulases (CMCase) and citric acid-producing isolates. All the tested fungal isolates exhibited varying amounts of acid production on Czapek’s dextrose (Cz-Dox) solid medium containing CaCO3. The highest concentration of citric acid produced using a Cz-Dox liquid medium was 8.49 ±2 g/L as recorded by A. brasiliensis Am 27. This amount of citric acid is equivalent to 29.22% of initial sugar. A.niger Am 270 showed the highest endo-cellulases production (0.73±0.2 IU/mL) whereas A. niger Am 258 exhibited the highest citric acid yield (14.74%). These isolates were chosen for the maximization of citric acid production from sugarcane bagasse. The highest amount of citric acid from sugarcane bagasse medium by A. niger Am 258 was obtained after 10 days of incubation, recording 34 g/L citric acid and by increasing the incubation period, the obtained amount of citric acid decreased. Whereas the mixed cultures of Am 270 and Am 258 strains revealed a slight enhancement of citric acid production recording 35.1 g/L citric acid after 8 days of the total incubation period.

Many efforts have conducted to approach the most proper alternative decolorants. The present study is focusing on investigation of cationic color precipitants “CCP” as alternatives of “H2O2” in clarification of raw sugar melt in Egypt. The experiments have performed using a pilot plant at Quos sugar factory, Qena governorate, Egypt. In these experiments, a comparison between two types of “CCP” (S TYPE 20 and TACELENE 4015) have been evaluated from the standpoint of decolorization efficiency. The behavior of the most effective matter has studied via the effect of dosage, pH, retention time and feeding point on the decolorization efficiency. A comparison between S TYPE 20 and hydrogen peroxide H2O2 in decolorization of raw sugar melt has conducted. The results show that, (S TYPE 20) is more effective than (TACELENE 4015) with percentage of color removal of 33.11% and 20.70% respectively. In addition, the results 64 Hazem F. et al. (2021), Egyptian Sugar Journal, Vol.17 ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ revealed that the proper experimental conditions for application S TYPE-20 are 7.4-pH, 30-minutes retention time and 100-ppm dosage. Addition of S TYPE 20 after clarification is the most proper feeding point. The results of comparison between S TYPE 20 and H2O2 show that decolorization percent are 40.40% and 27.70% respectively. Depending on these results, we concluded that the cationic color precipitants can be used successfully as decolorizing agents to replace hydrogen peroxide.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87653604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Egypt, sugar beet has acquired more importance and becoming an important source of refined sugar. Large amounts of beet sugar byproducts are produced resulting in environmental pollution. The surface application of molasses has significantly increased root yield, and the highest root yields were produced from either the control treatment and the application of 150 L/fed. of molasses to the soil surface. The highest root yield values were produced from the Belino variety under the control treatment and the Kawimera variety under the surface application of 150 L/ fed. of molasses. Surface application of molasses at the rate of 150 L/ fed. resulted in the highest sugar content. The highest values of the quality index, recoverable sugar (RS%) and recoverable sugar yield (RSY) from the Belino and Kawimera varieties were produced from the surface application of 150 L/ fed. of molasses.
