Abstract: A field experiment was conducted during cropping seasons of 2015–16 and 2016-17 at Instructional cum research farm RMD CARS Ambikapur to evaluate sugarcane mid–late varieties (Co 86032,Co 62175, CoT 8201) under 6 levels of nutrient management (N1) RDF (250:80:80 NPK Kg ha-1), (N2) 125%RDF (N3) 150% RDF, (N4) RDF+FYM @10 t ha-1, (N5)RDF+ Poultry manure @ 2 .0 ha-1 (N6) RDF +Vermicompost @2.5 t ha. Higher growth in terms of shoots (121.46 x103 ha-1), millable cane length 238.05 (cm), total dry matter yield (41.80 t ha-1) and yield attributes Viz. number of millable cane (87.62 x103 ha-1), cane weight cane yield (109.25 t ha-1) and CCS yield (11.61 t ha-1) were recorded highest with Co 86032, respectively. Variety ‘Co 86032’ showed non significantly values on quality parameters of brix%, pol %, purity % in juice across the planting season. Variety ‘Co 86032’ gave the maximum net returns (Rs 256867.61 ha-1) and benefit: cost ratio (3.64). Genotype Co 86032 gave better yield, Significantly higher shoots (122.65 thousand/ha), millable cane length (250.79 cm), dry matter yield (43.14 t ha-1), cane girth (8.35 cm), number of millable canes (93.15 x103 ha-1) and cane yield (113.74 t ha-1) net returns (Rs 273943.00 ha-1) and benefit: cost ratio (4.07) obtained with the application of 150% RDF respectively.
