Rice is the most popular kharif food crop grown in North India. In Punjab, 75–80% of area under rice is machine-harvested and based on harvest index, 18–20 million tonnes of rice straw production is estimated. Approximately 95% of paddy straw and 25% of wheat straw are burnt every year in Punjab, making the state the major culprit for greenhouse gas emissions. The emissions from wheat crop residues in Punjab are relatively low compared to those from paddy fields. Residue burning in agricultural fields of North India is a major source of smoke, smog and particulate pollution.
