Effect of sowing date and variety on the yield of tropical sugarbeet

A field experiment was conducted at the Agronomy Field, Bangladesh Agricultural

University, Mymensingh from November 2010 to April 2011. The experiment comprised

four sowing dates viz., 10 November, 20 November, 30 November and 10 December and

five varieties viz., Shubhra, Cauvery, EB- 0616, EB-0626 and EB-0809. The experiment

was laid out in a split plot design (SPD) with three replications. The results revealed that

both the variety and sowing date exerted significant influence on the yield of beet. The

highest beet yield (89.74 t ha-1) was obtained from the variety EB-0809 while EB-0626

gave the lowest beet yield (58.91 t ha-1). The highest beet yield (106.8 t ha ) was obtained

from 10 November sowing and the beet yield declined gradually with sowing afterwards.

The interaction of sowing date and variety showed significant effect on beet yield. The

variety EB-0809 produced the highest yield at 10 November sowing which was significantly

superior to that any other variety in combination with the sowing dates.
