Abstract: A field experiment was conducted to assess the effect of sowing time on yield and economics of different rice varieties under climatic condition of Konkan on lateritic soil having low to moderate soil fertility status during Kharif, 2013 and 2014. The experiment was laid out in split plot design with three main plot viz., sowing times and nine sub plot treatments viz., varieties. Thus, there were 27 treatment combinations, replicated three times. The pooled mean of data showed that the significantly higher grain yield was recorded by short duration hybrid Sahyadri-4 sown during 23^rd meteorological week followed by same hybrid sown during 24^th meteorological week and medium duration variety Jaya sown during 23^rd meteorological week. However, in case of straw yield in the pooled data, the significantly higher value was recorded by medium duration variety Karjat-5 sown during 23^rd meteorological week followed by same variety sown during 24^th meteorological week. In respect of economics of treatment combinations, the highest net returns and B:C ratio were obtained when rice crop was sown during 23^rd meteorological week with short duration hybrid Sahyadri-4 which was closely followed by the medium duration variety Jaya sown during 23^rd meteorological week.
