shubrha and Cauvery are suitable for intercropping with single and paired row sugarcane.
In both planting systems Cauvery performed better than shubrha as intercrop with
sugarcane. Sugar percent was almost similar in both planting systems and varieties of
sugarbeet.

Performance of sugarbeet varieties in different locations of Bangladesh:
The results of experiment setup in 12 sugar mills during 2011-12 cropping season
presented in the Table 2 showed that beet variety Shubrha produced average 78.0 t ha -1

and Cauvery produced 94.0 t ha of beet. The highest yield (106.21 t ha ) of the variety
-1
Shubrha was found at Thakurgaon sugar mills Ltd. and lowest (51.87 t ha ) was found at
Natore sugar mills Ltd. On the other hand, the highest yield of the variety Cauvery was
-1
found 135.85 t ha -1 at Syampur sugar mills Ltd. and lowest (54.34 t ha ) was found at
Natore sugar mills Ltd. Average sugar content was more or less similar in both of the
verities (Table 3). It is important to note that the sugar content in beet was ranged
between 10.57% to 15.75%. In saline area, Bagerhat where salinity level was 4-6 ds/m,
-1
-1
yield of sugarbeet were 67.0 t ha and 77.0 t ha in Shubrha and Cauvery respectively.
Mean pol % beet in that location was 13.08%. On the other hand, in Satkhira where
salinity level was higher (10-1 4 ds/m), beet yield were 100.0 t ha -1 and 120.0 t ha -1 in
Shubrha and Cauvery respectively but sugar content in beet (pol % beet) was found
comparatively lower (10.63%) than other places (Table 3).
