Sugar is obtained from root of sugar beet (
Beta vulgaris
L.) in addition to other sources. Three important economic parameters are often considered and these are root yield, sugar concentration in root juice and total sugar yield. All the three are affected by cropping period and use of fertilisers. Existing literature suggests the use of nitrogen and potash as fertilisers. An experiment over a period of three years with different combinations of N and K fertilisers for different cropping periods was carried out with multiple replicates. The highest root yield was obtained at a combination of N= 150 kg ha
-1, K = 155 kg ha
-1 and cropping period at160 days. The maximum sugar concentration was obtained at N = 120 kg ha
-1, K = 155 kg –1up> and cropping period at 130 days. The highest sugar yield was from N = 150 kg ha
-1, K = 155 kg ha
-1 and cropping period at 160 days. All factors and their interactions were statistically significant for all parameters assessed.
