Explanation:

Minimum Support Price (MSP) for Niger Seeds: The Government of India announces MSP for several crops to ensure that farmers get a reasonable price for their produce in the market. Niger seed is one of the crops for which MSP is provided.

Niger as a Kharif Crop: Niger (often referred to as "Ramtil" or "Khurasani" in India) is cultivated mainly as a Kharif crop. Kharif crops are sown with the beginning of the first rains during the onset of the southwest monsoon season, and they are harvested at the end of monsoon season.

Usage of Niger Seed Oil: Niger seeds yield a thick, edible oil that is an important item of diet in some regions of India, especially among tribal people. The oil is locally used for cooking purposes.
