A field experiment was carried out for two consecutive years during 2020-21 and 2021-22 in the research farm of OUAT, Bhubaneswar. The experiment was conducted in a strip plot design having four each of climate smart water and nutrient management approaches replicated four times. All the growth attributes like plant height, LAI, dry matter production as well as the yield attributing characters were superior under EFI with mulch and INM treatments in water and nitrogen management approaches, respectively. Optimal irrigation practice i.e. each furrow irrigation (EFI) with mulch in sweet corn resulted in higher cob yield (27.64 t/ha) followed by EFI alone. Similarly, INM practices comprising of 75% STBNR + 25% N through FYM produced higher cob yield (30.91 t/ha) as compared to other N-management options and was closely followed by STBNR.
