The field study was conducted to study the growth and yield of sweet corn with different fertilizer at the experimental farm of the Department ofAgrotechnology, Faculty of Agriculture, Universitas Sumatera Utara, Medan, Indonesia from May to August 2018. The experiment was laid out in a Randomized Complete Block Design (RCBD) with six treatments and three replication. Treatments include: 300 kg NPK/ha; 300 kg NPK/ha + 1.2 ton Rhizoculant/ha; 150 kg NPK/ha + 2.4 ton Rhizoculant/ha; 150 kg NPK/ha + 1.2 ton Rhizoculant/ha; 2.4 ton Rhizoculant/ha; and 1.2 ton Rhizoculant/ha. Results showed that fertilizer application had a significant effect on plant height, silking time, leaf area, and shoot-root ratio. The application of 300 kg NPK/ha + 1.2-ton Rhizoculant/ha produced higher values of growth and yield attributes rather than other treatments. The application of nutrients through Rhizoculant only was the lowest values of growth and yield attributes.
