Explanation:

Stubble burning is intentionally setting fire to the straw stubble that remains after grains, like paddy, wheat, etc., have been harvested. The practice was widespread until the 1990s, when governments increasingly restricted its use.

Explanation:

In Punjab and Haryana, the paddy crop is usually harvested between the first and last weeks of October. Farmers then sow the wheat crop from the first week of November until the middle of December.

These farmers regularly complain about the menace of rice straw – a product of mechanised agriculture – exacerbated by shortage of labour and lack of time. When paddy is harvested by a combined harvester and thresher, the machine leaves behind a significant length of straw and stubble on the field. This prevents other machines from sowing wheat seeds. With only 10-15 days between the rice-harvesting season and the wheat-sowing time, farmers often burn the stubble to quickly eliminate the paddy stubble. According to some estimates, farmers burned about 11 million tonnes of stubble in Punjab and Haryana, out of the 27 million tonnes of paddy stubble produced last year. The numbers are likely to be similar this year.

This way is very easy for them – but the huge clouds of smoke that rise up blow into Delhi, contributing significantly to the national capital’s notorious wintertime air pollution.
