Abstract: The agronomic investigation entitled, “Response of dry seeding of kharif paddy (Oryza sativa L.) varieties to different fertilizer Levels” was undertaken at Post Graduate Research Farm, Agronomy Section of Rajarshee Chhatrapati Shahu Maharaj College of Agriculture, Kolhapur (M.S.), India during kharif, 2019. The experiment was laid out in a split plot design with four replications and nine treatment combinations comprising of three varieties V1- Indrayani, V2- Phule Radha and V3- Bhogawati as main plot treatments and three fertilizer levels F1- 75% RDF, F2- 100% RDF and F3- 125% RDF as sub plot treatments on sandy clay loam soil. The yield contributing characters like number of panicles m-2 (343.97), panicle length plant-1 (24.63 cm), panicle weight plant-1 (11.79 g), number of spikelets panicle-1 (185.59), number of grains panicle-1 (180.06), grain weight plant-1 (20.22 g), 1000 grains weight (21.71 g) were also maximum with the variety Indrayani and which was at par with Bhogawati and significantly superior over Phule Radha. As a result the variety Indrayani had the higher grain yield (59.50 q ha-1), straw yield (86.75 q ha-1), biological yield (146.25 q ha-1) and harvest index (40.62%) which were statistically at par with Bhogawati and superior over Phule Radha. The yield contributing characters like number of panicles m-2 (338.88), panicle length plant-1 (25.43 cm), panicle weight plant-1 (12.25 g), number of spikelets panicle-1 (186.23), number of grains panicle-1 (181.04), grain weight plant-1 (20.69 g), 1000 grains weight (23.13 g) and grain yield (58.83 q ha-1), straw yield (87.73 q ha-1), biological yield (146.56 q ha-1) and harvest index (40.06%) were also significantly maximum with the application of 125% RDF ha-1 which was at par with application of 100% RDF ha-1 and significantly superior over 75% RDF ha-1. The effect of interaction between paddy varieties and fertilizer levels were significantly influenced the yield contributing characters. The paddy variety Indrayani when applied with 125% RDF ha-1 exhibited significantly superior yield attributes viz., number of panicles m-2 (348.55), panicle length plant-1 (28.02 cm), panicle weight plant-1 (14.82 g), number of spikelets panicle-1 (189.58), number of grains panicle-1 (184.95), grain weight plant-1 (23.15 g), and grain yield (64.62 q ha-1), straw yield (92.25 q ha-1), biological yield (156.87 q ha-1) and harvest index (41.18%) over rest of all the remaining interaction combinations.
