Abstract: A field experiment entitled “Economic viability of Sweet corn (Zea mays L. saccharata) cultivationas influenced by integrated nutrient management” was conducted during the kharif season of 2019-20 at Research farm ofAmbikapur. The experiment constituted of nine treatment combinations consisting three levels of organic manures (0 t, 3 t vermicompost and 5 t FYM) and three levels of inorganic fertilizers ( 50%, 75% and 100% RDF, where RDF is 120:60:40 kg ha-1 N, P2O5 and K2O) and replicated trice. Growth and yield attributes, husked, dehusked cob and fodder yield were influenced significantly due to organic and inorganic sources of nutrienyts. Maximum cob yield and fodder yield were recorded with3 t ha-1 vermicompost followed by 5 t ha-1 FYM, both were proved significantly superior to control. However 100% RDF recorded higher value of such parameters, which was significantly fair over 75% RDF and 50% RDF.Applicationof 5 t FYM ha-1 and 100% recommended dose of nutrients was economically viable as these producedsignificantly more net return.
Keywords: Sweet corn, vermicompost, integrated nutrient managemen
