Peer review
A 3-year study indicated that maize sown on October 22 took fewer days for seedling emergence, tassel emergence, silking and maturity than that sown on November 11 and December 1. Seedling emergence required similar growing degree days in all seedings, but the requirement at emergence of tassels, silking and maturity was in the order October 21 < November 11 < December 1. The models developed to predict the various pheno-phases with a 7°C base temperature proved superior to the models having a 10°C base temperature for north-west India.
