Abstract
A field experiment was conducted during kharif season of 2019 at Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) for evaluation of six rice genotypes (IET-27263, IET-26418, IET-26420, NDR-359, PD-19 and PD-26) under varying fertility levels (Control, 100% RDF, 150% RDF). Treatments were tested in Split Plot Design with three replications keeping fertilizer levels in main plots and genotypes in sub plots.
 Application of fertilizer at 150% RDF and genotype IET-27263 resulted in significantly taller plants, highest number of tillers, highest dry matter accumulation over all other fertilizer levels.
 So, it can be recommended that application of fertilizers at higher dose is essential for obtaining higher yield of rice as most of the parameters of growth, development and yield were responding well up to 150% RDF. The new rice genotype IET27263 was found superior to all other tested genotypes.
