Root yield increased linearly from 37.8 to 49.6 tons per acre when nitrogen rate increased from 50 to 200 pounds per acre. In contrast to yield, sucrose concentration decreased linearly from 16.9 to 16.1 percent when nitrogen rate was increased from 50 to 200 pounds per acre. Furthermore, with nitrogen rate increased, impurity value and percentage of sucrose loss to molasses also increased. CONCLUSION In this study, there was no significant difference in sugarbeet root yield between conventional and conservation tillage. Although the sucrose concentration was slightly lower under strip tillage, it did not result in total sugar yield (root yield multiplied by sucrose concentration) differences among the tillage treatments. No significant differences in sugar yields among the tillage treatments suggests that no-till practices can be adopted to reduce the expenses of labor and fuel, as well as reducing the impact of soil erosion and soil organic matter degradation. No tillage by nitrogen rate interactions indicates conservative tillage and conventional tillage have similar nitrogen requirements. Nitrogen application rate and timing need to be optimized for maximum economic returns, because higher nitrogen rate will result in higher root tonnage, lower sucrose concentration, and higher impurity value, thereby affecting sugarbeet price and transportation costs. n Chengci Chen, Reza Keshavarz Afshar, Abdelaziz Nilahyane and Ronald Brown are researchers with Montana State University's Eastern Agricultural Research Center.
