An experiment was conducted at Agricultural Research Station, Mudhol, Bagalkot district, Karnataka state to investigate the effect of tropical sugarbeet genotypes and N & K2O levels on growth, yield and quality of tropical sugarbeet. The experiment was laid out in split plot design and replicated thrice. Three sugarbeet genotypes were assigned to main plot viz., V1: SZ 35, V2: PAC 60008 and V3: Magnolia. Five N and K2O levels were assigned to sub plot such as 100, 120, 140, 160 and 180 kg N and K2O ha-1. The experimental results revealed that significantly higher plant height, number of leaves plant-1, leaf area index (LAI) and total dry matter production was recorded in Magnolia genotype than the others. The same genotype recorded higher root and top yield. Among the fertilizer levels application of N and K2O @ 160 kg ha-1 recorded significantly higher above mentioned growth parameters as well as root yield, but top yield was more with application of 180 kg N & K2O ha-1. Magnolia genotype with application of N and K2O @ 160 kg ha-1 was statistically found superior to all other treatment combinations. SZ 35 and PAC 60008 genotypes were found superior in terms of brix and pol per cent. Higher levels of fertilizers reduced the brix and pol percentage.
