An experiment was conducted at Horticultural Research Station, during the rainy (kharif) and winter (rabi) seasons of 2015–16 and 2016–17 at Adilabad, Telangana, to study the effect of nutrient-management practices on productivity, profitability and energetics of baby corn (Zea mays L.)–hyacinth bean (Lablab purpureus subsp. Purpureus) cropping system in a randomized block design, replicated thrice. Treatments comprised 100% recommended dose of fertilizer (RDF), 25% N supplemented through FYM or vermicompost + 75% RDF with or without bio-fertilizers Azospirillum and Bacillus megaterium @ 5 kg/ha each in addition to the control. Each main treatment was divided into 4 sub-plots and the treatments of 100% RDF (20 kg N and 22 kg p/ha) and 75% RDF, both with or without Bradyrhizobium @ 500 g/ha (seed treatment) were imposed for hyacinth bean in the winter season and data of the winter season of 2015–16 and 2016–17 were analyzed in split-plot design. Application of 25% N through vermicompost in conjunction with 75% RDF and bio-fertilizer to baby corn during the rainy season and 100% RDF along with seed treatment with Bradyrhizobium to hyacinth bean during the winter season resulted in significantly higher system productivity, gross and net returns, benefit: cost ratio, gross energy output, energy efficiency and net energy over rest of the treatments.
