Cultivar specific nitrogen and potassium recommendations optimize yield and quality attributes in sugar beet.

ABSTRACT: This study aimed to investigate cultivar-specific responses to nitrogen and potassium fertilization in sugar beet (Beta vulgaris) to optimize yield, quality attributes, and fertilizer use efficiency. Five sugar beet cultivars (Indira, Carma, Mallak, Melodia, and Shantala) were evaluated under nine fertilization treatments combining three nitrogen and potassium levels (T1 (144 N,0 K); T2 (144 N,60 K); T3 (144 N,120 K); T4 (216 N,0 K); T5 (216 N,60K2);T6 (216 N,120 K); T7 (288 N,0 K); T8 (288 N,60 K); T9 (288 N,120 K)) in a split-plot design over two growing seasons (2020/2021 and 202120/22 ). Significant cultivar × treatment interactions (p < 0.001) were observed across all parameters. Root yield ranged from 55.72 t/ha (Indira) to 83.33 t/ha (Shantala under T2 treatment).
