Bio-economic efficiency of maize - legumes based intercropping systems under different fertility treatments and its effects on subsequent wheat crop were evaluated at National Agriculture Research Center (NARC) Islamabad Pakistan. Cropping systems were kept in vertical blocks and fertility treatments in horizontal blocks replicated thrice with RCBD split block set up. Sole black gram, maize + black gram intercropping with maize and five fertility treatments (control; inoculation ( maize seed with plant growth promoting rhizobacteria (PGPR) and legumes seed with rhizobium strain (TAL 169) + PK (80-60 kg. ha-1 ), (120-80-60 NPK kg. ha-1 ); poultry manure at the rate of 15 t. ha-1 , and half poultry manure (7.5 t. ha-1 ) + half PK (40-30 kg. ha-1 ) + inoculation with PGPR for maize and TAL 169 for legumes) were included in research trials. Maximum seed yield, biological yield, 1000 grain weight and harvest index of black gram were in PK + rhizobium treatment. Highest yield and yield contributing factors were observed in sole black gram compared to intercropping with maize. Tallest plants, number of pods per plant and maximum number of seeds per pod of black gram were observed in PK+ rhizobium treatment. Maximum number of nodules and shoot N of black gram was observed in mineral PK + rhizobium treatment.
