| dc.description | Potato (Solanum tuberosum L.) is a herbaceous, edible tuber crop belonging to
the family Solanaceae. It is one of the most important food crops grown in
more than 100 countries in the world (Anonymous, 2009). Its center of origin
is said to be Peru and Bolivia (Ahmad, 1977). Potato was introduced in this
subcontinent in the sixteenth century. It was grown then in small plots as a
vegetable. Potatoes have been grown in Bangladesh since the 19" century. By
the 1920s, the first commercial production of the crop was established in the
country (Islam, 1983). Over one billion people consume potato worldwide and
it is the staple diet of half a billion people in developing countries. Because of
the dry matter, edible energy and edible protein content, potato is considered
nutritionally a superior vegetable as well as a versatile food item not only in
our country but also throughout the world. Potato ranks fourth in the world
(325.30 million tons) and third in Bangladesh (8.0 million tons) with respect to
food production and it is the first most important vegetable crop of our country
(Anonymous, 2007). Now a days, potato has emerged as a major food crop in
Bangladesh and is being cultivated throughout the country. The total
production of potato is 6648 thousand tons from the area of 401 thousands
hectares (Anonymous, 2008). The production of potato in Bangladesh is
remarkably low to many other potato growing countries. The yield of potato in
Bangladesh is 12.7 t/ha, whereas it is about 16.2 t/ha in India, 13.5 t/ha in
Indonesia, 29.9 t/ha in Japan and 25.9 t/ha in Australia (Hussain, 1995). | en_US |
| dc.description.abstract | An experiment was carried out at the Hajee Mohammad Danesh Science and
Technology University, Dinajpur, Bangladesh during the cropping season
2009-2010 to determine the effect of different management practices and
planting dates against bacterial wilt [Ralstonia solanacearum(Smith)Y abuchhi
et al.] of potato. A total of eight management practices viz. Cut tuber + Seed
treatment with cupravit 5Owp, Cut tuber + Soil treatment with bleaching
powder, Cut tuber + Soil amendment with bio-fungicide, Control (Cut tuber),
Whole tuber + Seed treatment with cupravit 50wp, Whole tuber + Soil
treatment with bleaching powder, Whole tuber + Soil amendment with biofungicide and Control (Whole tuber) and three planting dates viz. 10
November; 25" November and 10" December were used. Cupravit 50wp and
bleaching powder were used as seed and soil treating chemicals where biofungicide (Trichoderma harzianum) was applied for soil amendment. The wilt
incidence and percentage of dead plants were significantly lower in all the
management practices excluding Cut tuber and Whole tuber as Control plots.
The lowest (3.23%) wilt incidence was recorded in the management practice of
Whole tuber + Soil treatment with bleaching powder followed by 4.16% in Cut
tuber + Soil treatment with bleaching powder. Other management practices
also reduced disease intensity over Cut tuber and Whole tuber as Control plots
but disease incidence was lower in whole tuber plots than Cut tuber plots.
Regarding the dates, 25" November planting resulted significant effect in
reducing wilt incidence (3.98%) and percentage of dead plants (3.38%) where
higher incidences (10.07 and 9.02%, respectively) were found in 10"
December planting. The number of tuber per hill (9.62), yield per hill (448.6 g)
and yield (26.07 t/ha) were significantly the highest in management practice of
Whole tuber + Soil treatment with bleaching powder than Cut tuber plot as
Control plot (7.72, 344.9g and 20.77 t/ha, respectively). The yield and yield
parameters of potato varied significantly in different planting dates. The
significantly highest number of tuber per hill (9.63), yield of tuber per hill
(452.6 g) and yield (26.83 t/ha) were recorded in 25" November planting and
the lowest (7.48, 324.1g and 18.97 t/ha, respectively) in 10° December
planting. Therefore, it may be concluded that planting of whole tubers and soil
treatment with bleaching powder played significantly the highest role in
reducing bacterial wilt incidence and increasing yield. Planting of 25"
November was statistically significant in decreasing bacterial wilt incidence
and increasing yield. Soil amendments with bio-fungicide as eco- friendly
management practice also resulted better performance in reducing bacterial
wilt incidence and in increasing yield over controls. | en_US |
