There are three distinct crop seasons in the northern and interior parts of country, namely kharif, rabi and zaid.
The kharif season largely coincides with Southwest Monsoon under which the cultivation of tropical crops, such as rice, cotton, jute, jowar, bajra and tur is possible.
The rabi season begins with the onset of winter in October-November and ends in March-April.
The low temperature conditions during this season facilitate the cultivation of temperate and subtropical crops such as wheat, gram and mustard.
