Abstract: A field experiment was conducted to evaluate response of barley to mungbean residue (0, 10, 20 and 30 Mg ha^-1), nitrogen levels (0, 25, 50 and 75 kg ha^-1) and their interaction. Emergence m^-2 (50), plant height (109 cm), leaf area tiller^-1 (106 cm²), lodging score (5.55), termites attack (3.4%), grains spike^-1 (67), biological yield (12.80 Mg ha^-1) and grain yield (2.32 Mg ha^-1) were significantly (p=0.05) higher for 30 Mg ha^-1 mungbean residue compared to other levels. Similarly plant height (110 cm), lodging score (5.29) and biological yield (13.75 Mg ha^-1) were higher at 75 kg ha^-1 N compared to other levels of N. Productive tillers m^-2, grains spike^-1, 1000 grain weight, grain yield and harvest index were optimum at 50 kg ha^-1 N as compared to 75 kg ha^-1 N that encouraged lodging. Interaction between residue and nitrogen indicated that 10 Mg residue and 50 kg N ha^-1 is recommended to achieve maximum net return under comparable conditions.
