The local names of rice crops produced in Northern India in winter are

Concept

Rice crops are classified by the season in which they mature and are harvested, while regional names may refer to the same seasonal class in different parts of India. A name must therefore be matched to its season and region before it is grouped with other labels.

Application

In the winter-rice group, Aman is the regional name used in Bengal, Aghani is used in Bihar and Uttar Pradesh, and Sali (also written Shali) is used in Assam. These three names refer to the same broad seasonal rice category in their respective regions.

Contrast

• Aman, Aghani and Aus combines two winter-rice names with Aus, which denotes an earlier autumn rice crop.

• Aman, Aus and Sali also includes Aus, so the grouping does not consist entirely of winter-rice names.

• More than one of the above would require at least two complete groupings to fit the winter-rice category; the regional-name classification does not support that.

• None of the above would require every listed grouping to fail; one complete grouping is supported by the regional-name classification.

Result

Therefore, the local names of winter rice are Aman, Sali and Aghani.
