Interaction effect of variety and fertilizer
Brix percentage was significantly influenced by interaction between variety and
fertilizer Table 3. The highest brix (19.19 %) in sugarbeet was produced by interaction
between Cauvery variety and Control (No fertilizer) fertilizer dose, and the lowest brix %
(16.36 %) of sugarbeet was recorded with the interaction between Shubrha variety and T 3

Economic performance
The economic performance of different levels of variety and fertilizer doses on
sugarbeet (AEZ 11) is presented in Table 4. The highest Marginal Benefit Cost Ratio
(MBCR) 6.27 was obtained in interaction between the variety Cauvery and T 2 MOC 625

was found the most economically profitable.
