Which tribe celebrates the Ghaila and Beedadi festivals?

The Ghaila and Beedadi (Bidri) festivals are celebrated by the Gond tribe of Madhya Pradesh. Ghaila is the earthen-pot ceremony performed in the month of Jyeshtha (May-June) before the fields are prepared, while Beedadi (Bidri) marks the beginning of the sowing season in Gondwana, when a sacrifice is offered to propitiate Thakur Dev for a good harvest. Both are agricultural festivals tied to the Gond agrarian calendar, which is why the correct answer is the Gond tribe.
