Abstract: An experiment was conducted at Bangabandhu Academy for Poverty Alleviation and Rural Development (BAPARD) Agricultural Farm, Kotalipara, Gopalganj during 01 January, 2021 to 20 May, 2021 to find out the vegetative growth and yield performance of sweet corn at different combinations of organic and chemical fertilizers. Five treatments were selected where T0 was only cowdung (Control), T1 was Cowdung+ Urea+ TSP+ MoP, T2 was Cowdung+ Urea+ TSP+ MoP+ Gypsam, T3 was Cowdung+ Urea+ TSP+ MoP+ Gypsam+ Zinc sulphate and T4 was Cowdung+ Urea+ TSP+ MoP + Gypsam+ Zinc sulphate+ Boric acid. Plant height and number of leaves at 25 DAS, 50 DAS, 75 DAS and 100 DAS were significantly increased except number of leaves/plant at 25 DAS. Maximum stalk weight per plant (186.90gm), stalk yield (12.46 t/ha), ear height (84.47cm), weight per cob (111.62gm), Cob length (18.52cm), number of rows of seeds per cob (15.27), number of grain per cob (421.80), grain weight per cob(79.17gm) and 100 seed weight (18.77gm) were found in T4. But maximum shelling percentage (75.06) was found in T3. The highest grain yield and Stover yield were found were 5.28 t/ha and 14.32 t/ha respectively in T4. Maximum 233.63% yield was increased over control in case of using organic and inorganic fertilizers at optimum dose. However, it was evident from the present study that using of organic and inorganic fertilizers maximizes the vegetative growth and yield of sweet corn at experimental area of Gopalganj district in Bangladesh.
