A field experiment was carried out during the winter seasons of 1999-2000 and 2000-2001 to assess the per- formance of zero tillage in wheat (Piticum aestivum L. emend. Fiori & Paol.) under varying levels of nitrogen. The pooled analysis of data revealed that grain yield and number of effective tillerslm 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 Nlha being at par resulted in significantly higher grain yield over 120 kg N/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 signifi- cantly up to 180 kg Nlha.References
