An experiment conducted to study the co-inoculation effects of Gluconacetobacter diazotrophicus and Herbaspirillum seropedicae on growth and yield of sweet corn (Zea mays L.var. Saccharata) indicated profound effect of interaction between bioinoculants and different doses of nitrogen on plant growth and grain yield of sweet corn. Integrated seed treatment with G. diazotrophicus and H. seropedicae along with application of 100%, 75% and 50% of the recommended dose of nitrogen, recorded the highest plant height and dry matter production of sweet corn. Furthermore, these treatments recorded the highest number of grains per cob, number of grains per row of cob, length and girth of cob, filled to unfilled grain ratio, grain weight per plant, cob weight per plant, 100-seed weight and grain yield of sweet corn. From results of the present investigation we infer that the combined seed bacterization with G. diazotrophicus and H. seropedicae along with application of 50% of the recommended dose of nitrogen is most economical for getting higher grain yield of sweet corn.
