Garvana Sankranti is celebrated in the month of October. We all know that the meaning of Garva is fertilizing or Bhruna. So on this day the paddy or rice tree starts Garva. So on this day if anyone puts the garva paddy in field then the production will be more on that year. In some areas the garva tree is known as Ankaranti Tree. There is also a good odia line : –
Age Bunu Pachhe Bunu,
Garvana ku Tunutunu.
