| dc.description | Knolkhol (Brassica oleraceae var. gongylodes), also known as “Ol-kopi” or
“Kholrabi”, is one of the winter vegetables of Bangladesh, a member of the family
Cruciferae. It is reported to have originated in the coastal countries of Western
Europe. It was introduced in India long back. According to Encyclopedia
Britannica, knolkhol was first described in the eighteenth century as another
cabbage of European origin. Knolkhol is characterized by the formation of tuber
which arises as thickening of the stem tissue above the cotyledons. This tuber
develops entirely above the ground. It is this portion which is used for vegetables,
though young leaves are also used in some parts. | en_US |
| dc.description.abstract | A field investigation was carried out at the Horticulture Farm, Hajee Mohammad
Danesh Science and Technology University, Dinajpur, Bangladesh from October,
2009 to January, 2010 to study the effect of seedling age and spacing on the
growth and yield of Knolkhol cv. Early005. The treatments consisted of three
seedling ages (25, 35 and 45 day old seedling) and three spacings (25cmx25cm,
30cmx30cm and 35cmx35cm), thereby making nine treatment combinations. The
two-factor experiment was laid out in Randomized Complete Block Design
(RCBD) with three replications.
Most of the yield components and yield were significantly influenced by different
levels of seedling ages and spacings. Twenty five day old seedling gave the highest
yield (22.57 t/ha) of knob and the lowest yield of knob (15.74 t/ha) was obtained
from the 45 day old seedling. Increased spacing was found to increase the knob
yield, plant height, number of leaf/plant, breadth and length of the largest
leaf/plant, leaf area index, diameter and thickness of knob. All those parameters
were found to be maximum at 35cmx35cm spacing except total yield per hectare.
The maximum yield of knob (23.74 t/ha) was obtained from minimum plant
spacing (25cmx25cm) while the minimum yield of knob (16.32 t/ha) was recorded
in 35cmx35cm spacing.
The combined effect of seedling age and spacing was statistically significant for
growth and yield of Knolkhol. The highest knob yield (27.51 t/ha) was obtained
from the combination of 25 day old seedling and 25cmx25cm spacing, whereas the
lowest knob yield (11.59 t/ha) was recorded in 45 days old seedling and
35cmx35cm spacing. Results of this experiment showed that 25 days old seedling
and 25cmx25cm plant spacing were suitable for Knolkhol production. | en_US |
