Rice is vulnerable to change in weather and its production continues to be a risky enterprise under unfavourable environments. Field experiment was carried out in split plot design with five dates of planting viz., 5th June, 20th June, 5th July, 20th July and 5th August as the main plot treatments and two varieties (Jyothi and Kanchana) as sub-plot treatments, with four replications during the kharif season of 2013 and 2014. Correlation analysis showed that crop duration decreased with increase in temperature and bright sunshine hours, whereas the relative humidity and rainfall showed positive influence on crop duration. The increased grain yield during early planting periods may be favoured by more amount of rainfall and reduction in grain yield during late plantings may be due to increased temperature and decreased rainfall. The crop duration and yield during 2014 was negatively influenced by increased temperatures and BSS compared to crops planted during 2013.
