ABSTRACT

An experiment was conducted at Bangladesh Sugarcrop Research Institute Rahmotpur sub-station, Barishal
to study the effect of different planting methods and seedling age on growth and yield of tropical sugarbeet.
The experiment under seven treatment viz. T1 = Direct seed sowing in ridge method, T2 = Poly bag seedling
age of 14 days, T3 = Soil bed seedling age of 14 days, T4 = Poly bag seedling age of 21 days, T5 = Soil bed
seedling age of 21 days, T6 = Poly bag seedling age of 28 days and T7 = Soil bed seedling age of 28 days.
Experiment was conducted during August 2018 to February 2019 in a Randomized Complete Block Design
with three replications. It was observed that the plant height of sugarbeet increased rapidly as T4 treatment
(52.56 cm). Number of leaves grow highest in T5 treatment (10.66). Circumference (cm) was highest in T3
treatment (15.2 cm). The highest Individual beet weight of sugar beet (789.67 g) observed under treatment
T4. The highest yield of sugar beet (70.67 t ha-1
) observed under treatment T4. The lowest yield of sugarbeet
(45.13 t ha-1
) observed under treatment T7. Percentage of Brix was highest in T1 treatment. It may be
concluded that T4= Poly bag seedling age of 21 days was better yield of sugarbeet.
Key words: Sugarbeet, planting method, seedling age.
Introduction
Sugarbeet (Beta vulgaris L.) is a winter season Sugarcrop. Sugar yielding crop Sugarbeet production in
world second place. Beet produced sugar is caller beet sugar. Some research in Sugarbeet Bangladesh
Agricultural University who is initial stage. North Africa, West Asia and South Europe were origin of
Sugarbeet. 17-200C temperature need for germination in sugarbeet (Alam et al., 2001). Some line
innovated by BAU was K.Fizapolly, M. Resistapolly, Ramuskapolly, M. Marvipolly, ECI-2, M.
Magnapolly and OPH. Fertile Sandy silt soil is better for Sugarbeet cultivation. Slightly acidic, slightly
alkali and slightly saline can tolerate Sugarbeet crop. It requires about 150-165 days for maturing.
Sugarbeet is a promising crop in our country to mitigate sugar deficit. Yield as well as quality of any crop
depends upon the suitable planting method of that crop. For successful cultivation of sugar beet
development of suitable planting method is necessary. On the other hand, due to late shower in our country
land preparation cannot be possible in the months of September to 1st week of October (BSRI 2017). But
sugarbeet can be planted following some techniques in those months in medium high land of southern
region of Bangladesh. So, from this experiment suitable planting methods and seedling age of sugarbeet
will be identified.
Materials and Methods
An experiment was conducted at Bangladesh Sugarcrop Research Institute Rahmotpur sub-station, Barishal
to study the effect of different planting methods and seedling age on growth and yield of tropical sugarbeet.
The Sugar Beet seeds were collected from Bangladesh Sugarcrop Research Institute, Ishurdi, Pabna. BSRI
Sugar Beet-1 was selected for the study. Seven treatments were used in the experiment viz. T1
: Direct seed
sowing in ridge method, T2
: Poly bag seedling age of 14 days, T3
: Soil bed seedling age of 14 days, T4
: Poly
