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 content of N, P and K (%) in grain and straw, total uptake of nutrients (NPK kg ha-1) by paddy crop and available N, P and K kg ha-1 in soil after harvest were influenced significantly due to different treatments. The content of N, P and K in grain were (1.24%, 0.31% & 0.14%) and straw (0.78%, 0.19% & 1.49%) respectively, total uptake of nutrients were (142.66, 35.85 & 138.56 NPK kg ha-1) respectively by paddy crop were found significantly maximum with the variety Indrayani followed by Bhogawati and which was superior over Phule Radha. Available N, P and K were (268.09, 36.42 & 277.17 NPK kg ha-1) respectively in soil after harvest were found significantly maximum with the variety Phule Radha followed by Bhogawati which was superior over Indrayani. The content of N, P and K in grain were (1.29%, 0.31% & 0.14%) and straw (0.79%, 0.20% & 1.49%) respectively, total uptake of nutrients were (146.35, 36.85 & 140.19 NPK kg ha-1) respectively by paddy crop and available N, P and K were (267.24, 37.22 & 289.91 NPK kg ha-1) respectively in soil after harvest were found 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.
