Rice-wheat is a major crop rotation in the Indo-Gangetic region. Tillage is one of the major crop production operations and is an important contributor to the total cost of production. It is a common observation that direct tilling of any crop into combine-harvested rice stubbles from a reasonable rice yield is not possible without any prior burning or removal of straw. Therefore, presently crop residues in combine-harvested rice fields are being burnt causing a serious problem of atmospheric pollution. To solve the problem of straw management, continuous developments carried out in the Department of Farm Power and Machinery of Punjab Agriculture University have resulted in the development of a machine called "Happy Seeder".
