Abstract: A field experiment was conducted at Horticultural Research Station, SKLTSHU, Adilabad, Telangana State during rabi seasons of 2015-16 and 2016-17 to study the effect of Integrated Nutrient Management practices on growth and proximate characters of hyacinth bean in baby corn (Zea mays. L) – hyacinth bean (Lablab purpureus var. typicus) cropping system. Experiment was laid in Randomized Block Design for baby corn during kharif 2015 with seven treatments comprised of 100% recommended dose of fertilizers (RDF 150:27:50 N, P and K kg/ha), 25% N supplemented through farm yard manure or vermicomost + 75% RDF with or without bio-fertilizers Azospirillum and Bacillus megaterium @ 5 kg/ha each in addition to control and replicated thrice. Each main treatment was divided into four subplots and the treatments of 100% RDF (20-22 N, P kg/ha) and 75% RDF with or without Bradyrhizobium @ 500 g/ha (seed treatment) were imposed for hyacinth bean in rabi season and data of rabi 2015-16 and 2016-17 was analyzed in split plot design. Integration of 100% RDF with Bradyrhizobium seed treatment to hyacinth bean resulted in significantly higher plant height, LAI, nodule number per plant, higher protein content, less crude fiber of hyacinth bean over application of 75% RDF with or without Bradyrhizobium seed treatment and 100% RDF alone. Residual effect due to application of 75% RDF in conjunction with 25% N through FYM and biofertilizers imposed to preceding kharif baby corn resulted in significantly higher plant height, LAI, number of root nodules plant-1, protein content in succeeding rabi hyacinth bean crop than 100% RDF with or without biofertilizers and unfertilized control and was at par with integration of 75% RDF with 25% N through FYM or VC alone or 25% N through VC in conjunction with biofertilizers. Application of inorganic sources of nutrition integrated with organic manures (FYM or VC) to preceding baby corn crop during kharif showed significantly lower crude fibre content of succeeding hyacinth bean.
