How much is the loss in productivity due to late planting?
It is observed that right time for seeding of wheat in North-west parts of the IGP is around 10-15 November for good seed germination. In the eastern Gangetic plains wheat should be seeded by 3rd week of November for good yields. Any delay would result in 30-35Kg/ha /day loss in grain yields in North-west and 50-60kg/ha/day in eastern plains. Greater productivity losses in eastern parts are mainly due to shorter winter window.
