A field experiment was carried out during the winter seasons of 2007–2008 and 2008–2009 to assess the performance of zero tillage in wheat (Triticum aestivum L. Emend. Flori & Paol.) under varying levels of nitrogen. The pooled analysis of data revealed that grain yield and number of effective tillers/m row increased significantly by 7.7 and 6.6%, respectively, with zero tillage over conventional tillage. Significant reduction in dry weight of weeds was observed with zero tillage over conventional tillage. Application of 150 and 180 kg N/ha at par resulted in significant higher grain yield over 120 kg/ha. The growth and yield parameters showed significant variation owing to N application. The dry weight of weeds was minimum with 120 kg N and it increased significantly up to 180 kg N/ha.
