A field experiment was conducted at the research farm of the Department
of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University,
Gazipur, from November 2011 to May 2012 to find out the growth pattern
and optimum sowing date of tropical sugar beet in Bangladesh.
The
tropical sugar beet genotypes were Cauvery, Shubhra and EB0616, and
sowing dates were 01 November, 15 November, 01 December and 15 December.
The interaction effect of sowing dates and sugar beet genotypes was
statistically significant in growth
parameters like leave number, leaf area index (LAI), crop growth
rate (CGR), root weight per plant, root yield. The highest root yield
was obtained from genotypes EB0616 when sown on 01 November (103.5 t/ha)
and 15 November (100 t/ha).
The genotypes Cauvery and Shubhra gave
identical root yield i.e., 90.27 t/ha and 92.86 t/ha, respectively on 01
November sowing. Root yield significantly decreased in all the three
genotypes with the advancement of sowing dates from 01 November onwards.
For high root yield the optimum sowing date for tropical sugar beet in
Bangladesh seems to be in early November.
