Response of sugar beet to N, K, and Na applications in newly reclaimed soils of Minia governorate [electronic resource].

Includes references.

Two field esperiments were conducted in newly reclaimed soils, Beni Mazzar district, Minia Governorate, Egypt, to study the effect of nitrogen (0, 70 and 140 kg N/fed), potassium (0, 48 and 96 kg K,O/fed) and sodium (0, 75 and 150 kg Na/fcd) applications on yield and juice quality of sugar beet (Oscar Variety). The combination between the levels of the studied factors were arranged in a randomized complete block design of four replications. Results showed that increasing nitrogen level up to 140 kg N/fed resulted in an increases in root yield, sugar yield, total soluble solids, alpha-amino nitrogen and potassium content in the juice, while, sucrose content, purity percentage and sodium content in the juice decreased. Potassium application significantly increased root yield, sugar yield, total soluble solids and potassium content in the juice, while, sucrose content, purity percentage and sodium content in the juice responded negatively. Sodium application significantly increased root yield, sugar yield, total soluble solids and sodium content in the juice, but purity percentage and the potassium content in the juice responded negatively. However, Na application had no effect on sucrose percentage.
