Abstract: A field experiment was conducted in semi arid tropical region during kharif and rabi seasons of 2015-16 and 2016-17 to study the effect of integrated nutrient management practices on water productivity and profitability of baby corn in baby corn – hyacinth bean 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 vermicompost + 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 for kharif 2016 was analyzed in split plot design. Significantly higher water productivity, gross and net returns and higher B: C ratio were noticed with integration of 75% RDF with 25% N through vermicompost in conjunction with the biofertilizers (Azospirillum and Bacillus megaterium) during both the years of study over 100% RDF with or without biofertilizers, integration of 75% RDF with 25% N through FYM with or without biofertilizer and un-fertilized control. Integration of 100% RDF with Bradyrhizobium for seed treatment of hyacinth bean during rabi, 2015-16 resulted in significantly higher water productivity over 75% RDF with or without Bradyrhizobium seed treatment, higher gross and net returns of baby corn in the succeeding kharif season over 100% RDF alone, 75% RDF with or without Bradyrhizobium seed treatment.
