| dc.description | Onion (Allium cepa L.) is one of the most important bulb crops of the world. It
belongs to the family Alliaceae. Central Asia is the primary centre of its origin
and the Mediterranean area is the second centre for larger type of onion
(McCollum, 1976). Onion is considered as a spice in Bangladesh, although most
other countries have accepted it as vegetables. The dietary habit of Bangladeshi
people is very much tied up with onion and an average consumption of 25 g per
individual per day is considered essential (HRDP, 1995). The leading onion
producing countries of the world are China, India, Russia, Pakistan, Turkey,
Indonesia, Iran, Brazil and United Status of America (FAO, 2004).
Among the spices crops grown in Bangladesh onion ranks top both in respect of
production and area (BBS, 2005). It is cultivated in almost all districts of
Bangladesh, but widely cultivated in greater districts of Faridpur, Dhaka,
Rajshahi, Comilla, Mymensingh, Rangpur, Jessore and Pabna. During 2004-2005,
about 5,89,000 metric tons of onion bulbs were produced in Bangladesh from
86,235 hectares of land with an average yield of 6.83 t/ha (Appendix I), which is
very low as compared to that of other onion producing countries of the world. The
average yield of onion is about 17.45 t/ha in the world (Appendix II). | 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
November 2006 to April 2007 to study the effect of boron (B) and sulphur (S) on
the growth and yield of onion cv. Taherpuri. The treatments consisted of four
levels of boron (0, 0.5, 1.0 and 2.0 kg/ha) and sulphur (0, 15, 30 and 60 kg/ha)
each, thereby making sixteen treatment combinationsl. The two factor experiment
was laid out in the Randomized Complete Block Design (RCBD) with three
replications. Full doses of boron and sulphur were applied in the form of boric
acid and gypsum, respectively.
Most of the yield contributing characteristics and yield were significantly
influenced by the different levels of boron and sulphur. Boron @ 1.0 kg/ha gave
the highest (13.19 t/ha) yield of bulb and the lowest yield of bulb (8.49 t/ha) was
obtained from the control. Sulphur was found to increase the bulb yield by
increasing plant height, number of leaves per plant, fresh and dry weight of bulb,
and bulb diameter. The maximum yield of bulb yield (12.24 t/ha) was obtained
from 30 kg sulphur/ha and the minimum yield of bulb (9.94 t/ha) was recorded in
the control.
The combined effect of boron and sulphur was statistically significant for growth
and yield of onion. The highest bulb yield (15.38 t/ha), the maximum gross
income (Tk. 184560/ha) and the maximum net return (Tk. 112530/ha) were
obtained from combination of 1.0 kg boron and 30 kg sulphur/ha. The lowest bulb
yield (7.20 t/ha), the minimum gross income (Tk. 86400/ha) and the lowest net
return (Tk. 16554/ha) were recorded in the control. Boron was more effective in
combination with sulphur in increasing the yield. Results of this EXpetigneat
showed that application of 1.0 kg boron and 30 kg sulphur per hectare Were
economic for onion bulb production. | en_US |
