Pant Univ. of Agric. & Tech., Pantnagar during rabi season of 2004-2005 to study the effect of wheat genotypes, dates of sowing on growth, development, yield nutrient uptake and grain quality. The soil of the experiment plot was silty loam in texture with higher organic matter. Neutral in reaction, high available phosphorus and medium in available potassium content. The experiment was laid out in split plot design with three replication. Keeping two dates of sowing in main plot (December 15, 2004 (D1) and January 3, 2005 (D2) and four genotype of wheat DBW-16 (V1), PBW-373 (V2), UP-2425 (V3), and Raj-3765 (V4) in sub plots.December 15 sown crop resulted higher germination at 15 DAS, taller plants at most of the stages, significantly higher number of shoots, maximum total dry matte accumulation at various stages of crop growth were obtained. Days taken to 50 per cent heading and days taken to maturity were significantly affected by dates of sowing. Higher grain yield and nutrient uptake were recorded in December 15 sown crop. Protein content was also higher in December 15 sown crop than January 3. Among genotype DBW-16 gave significantly higher grain yield than all other genotypes reduction in grain yield (19.4) and straw yield (21.7%) were recorded in very late sown crop (January 3) in comparison to December 15 sown crop.ennullThesis
