A field experiment was conducted during season Kharif of 2016-17 to study the effect of weather parameters on the growth, yield attributes and yield of rice. The rice crop sown on 23rd Meteorological Week (MW) recorded significantly higher grain yield (5.83 t ha-1) and straw yield (6.99 t ha-1) over delayed sowing on 24th MW and 25th MW. Hybrid rice Sahyadri-4 recorded the maximum grain yield (5.79 t ha-1) as well as straw yield (6.94 t ha-1) which was at par with Jaya, Swarna, Karjat-3, Karjat-7, Karjat-5, Palghar-1 and significantly higher over Ratnagiri-24 and Karjat-2. Under the changing climatic conditions, sowing of rice was found suitable during 23rd meteorological week with early duration variety Sahyadri-4 followed by conventional variety Jaya and Swarna.
