Experimental results revealed that integrated application of 75% RDF + vermicompost @ 2.5 t/ha + mixed bio-fertilizers (Azosirillum + Azotobacter + phosphorus solubilizing bacteria) significantly augmented the baby corn yield attributes along with baby corn (1.50 t/ha) and green forage (26.03 t/ha) yield. The conjunctive use of 75% RDF + FYM @ 5 t/ha + mixed bio fertilizers applied to preceding baby corn recorded the maximum seed yield (620 kg/ha) and stick yield (950 kg/ha) in green gram being at par with residual effect of 75% RDF + vermicompost @ 2.5 t/ha + mixed bio fertilizers. The system yield was enhanced with application of 75% RDF + vermicompost @ 2.5 t/ha + mixed bio-fertilizers applied to baby corn producing the baby corn equivalent yield (2.20 t/ha) being remained at par with 75% RDF + FYM @ 5 t/ha + mixed bio-fertilizers. Application of 75% RDF + vermicompost @ 2.5 t/ha + mixed bio-fertilizers registered the highest gross return (` 159131/ha) in baby corn green gram system when green gram was grown under residual fertility condition. But the combined use of 75% RDF + 5 t FYM/ha + mixed bio fertilizer in preceding baby corn incurred the maximum net return (` 102269/ha) and benefit cost ratio of 2.82 in baby corn-green gram sequence.
System yield and gross return was enhanced with application of 75% NPK + vermicompost @ 2.5 t/ha + mixed bio fertilizers.
