Background: In most areas where corn is sown, the crop growth is usually affected by low available nitrogen. The experiment was carried out during 2019 Kharif seasons to investigate the effect of integrated nutrient management on growth, yield attributes, yield and economics of sweet corn under northern tract condition of Madhya Pradesh. Methods: The experiment was laid out in randomized block design with three replicates. Observations were recorded on growth parameters (plant height, dry matter accumulation), yield attributes (number of cobs per plant, number of rows per cob, number of grains per cob, cob length, grain weight per cob) and green cob yield and stover yield of sweet corn. Results: Revealed that combination of 75% RDF + BF + 25 % VC recorded higher mean growth parameters were plant height (196.4 cm), dry matter (193.45 g plant-1 ) and yield attributes were number of cobs per plant (1.60), length of cob (20.2 cm), number of rows per cob (16.5), number of grains per cob (612), grain weight per cob (126 g) and green cob yield & stover yield (18603 & 9770 kg ha-1 , respectively) as compared to rest of treatments, whereas above parameters lowest under absolute control. The practice of integration of 75% RDF + BF + 25 % VC gave maximum net returns of ? 306657 ha-1 compared to other treatments.
