Two field experiments were conducted at Wadi El-Natrun, El-Bahira Governorate, (latitude of 30.48 0 N and longitude of 30.50 0 E) in 2015/2016 and 2016/2017 seasons to study the effect of potassium humate and nitrogen fertilization and its impact on yield and quality of sugar beet sown in a sandy soil. The present work included twelve treatments, which were the combination of four potassium humate levels as soil additives (without, 4, 8 and 12 liter /fed) and three nitrogen rates (80, 100 and 120 kg N/fed). the treatments were arranged In strip plot design with four replicates. Potassium humate levels were occupied the vertical plots, while nitrogen rates were represented in horizontal plots. Results show that soil application of 8 and/or 12 l potassium humate/fed significantly exhibited higher values of leaf area index (LAI), root diameter, root and foliage fresh weight/plant, sucrose%, and quality index as well as extractable sugar%, root and sugar yields/fed in both seasons. Moreover, root potassium, sodium, α-amino N contents, alkalinity coefficient and sugar lost to molasses% were insignificantly affected by the studied potassium humate levels.Increasing nitrogen fertilizer from 80 up to 120 kg/fed positively enhanced LAI, root diameter, root and foliage fresh weights/plant in both seasons. Whilst, the highest sucrose, extractable sugar percentages, sugar and root yields/fed, quality index and alkalinity coefficient were obtained by the application of 100 kg N/fed. On the other hand, higher values of sugar lost to molasses% and non-sucrose components (K, Na and αamino -N) were detected in beets fertilized with 120 kg N/fed. Based, under conditions of the present work, application of 8 1/fed potassium humate and fertilized with 100 kg N/fed could recommend obtaining the highest root and sugar yields/fed.

The present work was carried out to evaluate four types of sweet sorghum syrup made from Mn 4080 sweet sorghum variety either alone or with one of three herbal extracts (tumeric, cinnamon and ginger) for the physicochemical, sensory and microbiological properties.The results indicated that sweet sorghum syrup contained cinnamon extract had the highest percentages of sugar profile, tannins, total phenolics, antioxidant activity and minerals (K, Ca and Fe). Moreover, purity and the degree of browning and darkening were increased. Organoleptically, syrup contained cinnamon extract had the highest score in the overall acceptance as compared with the other sorghum syrup types. The results also showed that extracts cinnamon herb played a good role in shelf-life stability during storage period at 25 ± 2°C up to 9 months.The present work suggests that the cinnamon extracts can be used as an antioxidant and to improve the palatability of sorghum syrup.

The present work was carried out at Mallawi Agricultural Research Station, El-Minya Governorate, Egypt (latitude of 28° 10' N, longitude of 30° 75' E and altitude of 55 m above sea level) in 2017/2018 and 2018/2019 seasons to study the influence of nitrogen, potassium as inorganic fertilizers and press mud as an organic fertilizer on yield and quality of sugarcane variety G.2003-47 (Giza 3). The field experimental work was carried out in a randomized complete blocks design in a split-split plot arrangement in three replications in both seasons. The results showed that the application of 4 tons of press mud/fed significantly increased plant length, diameter, number of millable canes/fed, stalk weight, cane and sugar yields/fed, as well as brix, sucrose and sugar recovery percentages in both seasons. Increasing nitrogen levels from 150 up to 210 kg N/fed resulted in a significant increase in stalk height, diameter, weight, number of millable canes cane and sugar yields/fed, as well as brix, sucrose, purity and sugar recovery percentages in both seasons. Applying 48 kg K2O/fed resulted in a significant increase in cane length, diameter, number of millable canes, stalk weight and cane and sugar yields/fed, as well as brix, sucrose and sugar recovery percentages in both seasons. The correlation analysis showed that the stalk diameter, number of stalks per meter, and weight of the cane contributed most to cane yield at the harvest.
