Effect of zero and minimum tillage in conjunction with nitrogen management in wheat (Triticum aestivum) after rice (Oryza sativa)

An experiment was conducted to find out the effect of tillage and nitrogen management on the productivity of wheat (Triticum aestivum L. emend. Fiori & Paol.) after rice (Oryza sativa L.) during winter seasons of 1997–98 and 1998–99 at Faizabad, Uttar Pradesh. Sowing of wheat by Chinese seeder recorder significantly higher values of growth characters, yield attributes, yield and nitrogen uptake by wheat followed by Pantnagar zero till drill and lowest in conventional tillage. Chinese seeder recorded 23.83 and 25.85% more grain yield over conventional tillage during first and second year respectively. All the growth characters, yield attributes, yield and N uptake were significantly higher with 150 kg N/ha over 120 kg N/ha. Application of N as half basal + half after first irrigation recorded significantly higher yield and N uptake over rest of the treatments but test weight was higher with the application of N as half after first irrigation + half after second irrigation.
