Effect of mungbean residue and nitrogen levels on barley

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 cm),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.
