Abstract
Two field trials were carried out at Shandaweel Rescarch Station (Sohag Governorate) in the two successive growing seasons of 1997/ 1998 and 1998/1999 to study the effect of nine treatments representing the combinations between three nitrogen levels (0,46 and 92 kg N/ fed) and three potassium levels (0,24 and 48 kg K20/fed) on yield and quality of sugar beet variety Del. 939. A complete randomized block design in four replications was used. The obtained results showed that increasing N-level up to 92 kg N/fed increased root fresh weight/plant. root and sugar yield significantly while sucrose percentage decreased. Increasing K-level from zero to 48 kg K20/fed positively increased root fresh weight/plant, sugar yield and sucrose percentage. Root yield insignificantly inceased as K-level increased up to 48 kg K20/fed. Purity percentage was not significantly affected by the applied levels of N and K fertilizers.
