Abstract: A field experiment was conducted during kharif seasons of 2016 to determine the effect of different transplanting dates and spacing on growth and yield of rice (Oryza sativa L.) under kharif condition of Konkan. The experiment was laid out as a strip plot design with three replications provided with four main treatments (Transplanting dates) T1 -21 DAS, T2 -31 DAS, T3 - 41 DAS, T4 - 51 DAS and three sub treatments Spacing, S1 (20cm x 15cm), S2 (15cm x 15 cm), S3 (20 cm x 10 cm). Ratnagiri -24 variety of rice used for experiment and the experiment comprised of 12 treatments, viz T1S1, T1S2, T1S3, T2S1, T2S2, T2S3, T3S1, T3S2, T3S3, T4S1, T4S2, T4S3.Observations on number of panicle, length of panicle, no. of productive tillers, number of fertile grain per panicle,1000 grain weight, number of grains per plant, grain yield, straw yield and harvest index. Transplanting of 21 days old seedling T1 recorded maximum value for grain yield (25.45g), straw yield (21.15g) and harvest index (56.20%). Spacing 20cmx15cm recorded grain yield/ plant (20.68g) and spacing 20cmx 10cm (19.37g) but maximum grain yield / plot obtained by closer spacing S3 20cm x 10 cm.
