Abstract: The present investigation entitled “Performance of summer paddy varieties under fertilizer levels in relation to weather parameters” was carried out during summer, 2014 at Agricultural Research Station farm, Vadgaon Maval, Tal- Maval, Dist- Pune. The field experiment was laid out in a split plot design with three replications. There were sixteen treatment combinations comprising of four varieties VDN-3-51-18 (Indrayani), VDN-99-29 (Phule Samruddhi), IET-13549 (Bhogawati) and RDN-99-1 (Phule Radha) as main plot treatments and four fertilizer levels (F₁-75% RDF through straight fertilizers, F₂-100% RDF through straight fertilizers, F₃125% RDF through straight fertilizers and F₄-RDF through Urea DAP form(57:29:00)+50 KgK₂O )as sub plot treatments. The gross and net plot size were 2.95 m x 2.95 m and 2.55 m x 2.55 m, respectively. A spacing of 15-25 cm x 15-25 cm was adopted. Among the four different varieties of paddy, VDN-99-29 (Phule Samruddhi) recorded significantly higher growth and yield components resulted in increased yield as compared to VDN-3-51-18 (Indrayani), IET-13549 (Bhogawati) and RDN-99-1 (Phule Radha). It would be, therefore, suggested to adopt VDN-99-29 (Phule Samruddhi) variety for summer paddy cultivation under Vadgaon Mavalconditions. The application of fertilizer with 125% RDF through straight fertilizers favorably influenced all the growth and yield components which was at par with fertilizer through Urea DAP briquette form (57:27:00)+50 Kg K₂O ha¹ as compared to other fertilizer levels of paddy with 75%RDF through straight fertilizers,100%(100:50:50) through straight fertilizers. It would be, advisable either to apply 125% RDF through straight fertilizers or application of fertilizer through Urea DAP briquette form (57:29:00)+50KgK₂O ha^-1 to summer paddy variety Phule Samruddhi. In summer season, VDN-99-29 (Phule Samruddhi) variety of paddy fertilized with either 125% RDF through straight fertilizers or application of fertilizer through Urea DAP briquette form (57:29:00)+50 Kg K₂O ha^-1 favorably influenced growth and yield components as compared to other interactions formed due to varieties and fertilizer levels.
