A field experiment was conducted at Research cum Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) in Rabi season of 2014 to evaluate different agrotechniques for enhancing profitability of sweet corn under Chhattisgarh plains condition. Different agro input management practices had significant effect on growth, yield attributes and yield of sweet corn. RDF + 10 t FYM ha^-1 (T₂) resulted in better growth and yield attributes in term of highest plant height, stem girth, leaf area index, dry matter accumulation, CGR, cobs plant^-1, cob weight, grain rows cob^-1, grains row-1, green cob yield (187.74 q ha^-1), grain yield (34.80 q ha^-1) and green fodder yield (328.72 q ha^-1). Application of RDF + 5 t FYM ha^-1 + 2% foliar spray of 18:18:18 N: P: K at 40 and 60 DAS (T7) and RDF + 10t Rice straw compost (Trichoderma based) ha^-1 (T4) was also found statistically at par in term of yield with the treatment of T₂.With respect to the economics, RDF + 10 t FYM ha^-1 (T₂) continue to maintain its superiority in term of higher net returns (Rs 152646.54). However, in term of B: C ratio application of RDF + 5 t FYM ha^-1 + 2% foliar spray of 18:18:18 N:P:K at 40 and 60 DAS (T₇).As per the availability of less amount of FYM, 2 % foliar application of 18:18:18 N:P:K at 40 and 60 DAS could be the substitute of FYM. In order to the superiority 10 t ha-1rice straw (Trichoderma based) could be the substitute of 10 t of FYM. Thus, it may be inferred that among the different agro input management practices, RDF + 10 t FYM ha-1 (T₂) resulted in maximum green cob yields and net profits.
