| dc.description | Dinajpur is a familiar district of Bangladesh known as the capital of fine
aromatic rice Kataribhog rice.In 3437.98 square kilometers Dinajpur, rice is
cultivated on 4,18447 hectors in which aromatic rice is cultivated in 30%
land during “Aman” season occupying 16,853 hectors of land with the
production of 26,837 metric tons (DAE 2010). The climate and edaphic
conditions of Dinajpur is so much favorable for fine aromatic rice cultivation
where only cow dung is needed to supply nutrition, but the production of fine
aromatic rice per hectare in Bangladesh is remarkably low to many other
aromatic rice growing countries. The yield of fine aromatic rice in Dinajpur is
2.6 t/ha, whereas it is about 4.20 t/ha in India, 4.50 t/ha in Indonesia, 6.50 t/ha
in Japan and 6.20 t/ha in China (Hussain, 1995). A few number of
Kataribhog rice is exist in Bangladesh. Traditional types include Radhuni
Pagol, Phillipine Katari, Zota Katari, Tajmahol Katari, Jira Katari, Behula
bashor etc where some are not considered true Kataribhog and farmers are
growing by their own knowledge for dish purposes only. | en_US |
