In Goa, the harvest thanksgiving in which the first sheaves of paddy are blessed in church is known as:

The Konsachem Fest (also called the Feast of the First Sheaves or the Harvest Festival) is a thanksgiving festival of the Catholic community of Goa. It is celebrated in August, at the time of the first paddy harvest of the monsoon season.

The word "konsachem" comes from "kanso", meaning ears of grain (sheaves of paddy) in Konkani. On the day of the festival, the parish priest, accompanied by the people of the village, goes in a procession to a paddy field, where he blesses the crop and cuts the first sheaves of paddy. The sheaves are carried back in procession to the church, accompanied by music and prayers, and are offered at the altar during a special thanksgiving mass. The blessed sheaves are then distributed to the people, who take them home and place them at their altars, doors or in other parts of the house as a symbol of blessing and prosperity, praying for a good harvest and a year free from hunger. Some of the new rice is used to prepare special dishes, such as "pez" (rice gruel) and sweets. The festival is celebrated in several villages of Goa, such as Raia and Aldona, and in the city of Panaji, and the date varies from village to village.

The Konsachem Fest is an example of how the Catholic community of Goa has combined Christian traditions with the agricultural customs of the region. Similar harvest festivals, called Navem (new harvest), are celebrated by Goan Hindus at the same time.

Goa has many other festivals linked with the monsoon, such as Sao Joao (24 June), Sangodd (the feast of Saints Peter and Paul, 29 June), Chikal Kalo (the mud festival at Marcel) and Bonderam (the flag festival of Divar island, in August).

Why not the other options?

Sao Joao is the monsoon feast of St. John the Baptist, when young men jump into wells.

Bonderam is the flag festival of the island of Divar.

Sangodd is the feast of Saints Peter and Paul, with boat processions.
