Abstract:
The biggest challenge faced by Indian farmers under Rice- Wheat cropping system is the management of combine harvested rice. To manage such a huge quantity of rice residue farmers resort to burning. The burning of rice residue is not anymore, a solution for residue management as it has been banned by the Government of India due to its ill effects on the environment as well as on soil health. Rice residue contains around 0.7% N, 0.23% P, and 1.75% K and it is also an important source of micronutrients such as Zinc and is also rich in Silicon. Therefore, in-situ residue management is very crucial for protecting the environment as well as soil health. Two years field experiment was conducted to evaluate the effect of wheat establishment methods and rice residue levels on yield and economics of wheat and rice under rice-wheat cropping system at G. B Pant University of Agriculture and Technology, Pantnagar 2019-20 and 2020-21. The significantly higher grain and straw yield was observed under super seeder sown wheat during both the year of experimentation and the most economically feasible and environment-friendly treatment were super seeder sown wheat with loose straw removal treatment.
