Afield experiment was conducted during kharifseason 2015–16 to study the response of rice varieties to different sowing windows under Konkan conditions. The experiment was laid out in split plot design with three replications. The main plot treatments were three sowing windows, viz., 23^rd Met Week, 24th Met Week, 25th Met Week. The sub plot treatments comprised five rice varietiesviz., Karjat-5, Palghar-1, Jaya, Swarna and Karjat-2. Thus there were 45 treatment combinations. Results revealed that rice crop sown on 23^rd Met. Week recorded significantly higher grain yield (5782 kg ha⁻¹) and straw yield (6462 kg ha⁻¹). Long duration rice variety Swarna recorded the maximum grain yield (5782 kg ha⁻¹) as well as straw yield (6462 kg ha⁻¹), which was significantly higher over all other varieties under study except variety Jaya which was at par. From the present investigation it can be concluded that kharif rice in Konkan be sown during 23^rd meteorological week with rice variety Swarna followed by conventional variety Jaya, so as to obtain higher yield and economic returns.
