Abstract: The field experiment was conducted during summer season of 2013-14 and 2014-15 at the Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (CG) to influence of rice straw incorporation and nutrient management on energetic and yield of summer rice in Chhattisgarh plains. The result on energy output, energy output-input ratio and energy use efficiency where adjudged to be the best under treatment Trichoderma treated rice straw incorporation @ 5 t ha^-1 by disc harrowing twice fb irrigation at 30 DBT (S₄) and both were statistically similar to treatments rice straw incorporation @ 5 t ha^-1 by disc harrowing twice fb irrigation at 30 days before transplanting (DBT) (S₂) and rice straw incorporation @ 5 t ha^-1 by disc harrowing twice fb irrigation at 30 DBT + 10 kg N ha^-1 (S₃) during both the years and mean basis. Significantly highest grain and straw yield of summer rice was recorded under treatment rice straw incorporation @ 5 t ha^-1 by disc harrowing twice fb irrigation at 30 DBT + 10 kg N ha^-1 (S₃), which was at par to treatments rice straw incorporation @ 5 t ha^-1 by disc harrowing twice fb irrigation at 30 DBT (S₂) and Trichoderma treated rice straw incorporation @ 5 t ha^-1 by disc harrowing twice fb irrigation at 30 DBT (S₄) during both the years and on mean basis. Among the nutrient management revealed that significantly highest energy output, energy output-input ratio, energy use efficiency energy intensiveness, grain and straw yields were registered with treatment 150% RDF (180:90:60 kg N, P₂O₅ and K₂O ha^-1) (F₄) which was found to be at par to treatment 100% RDF (120:60:40 kg N, P₂O₅ and K₂O ha^-1) (F₃) during both the years and on mean basis.
