Sweet corn is one of the most popular food commodities in the community. However, production is still relatively low. The study aimed to determine the concentration and uptake of N and P nutrients, the development of mycorrhizae, and the growth of several varieties of sweet corn added with bioameliorants. The experimental design used was a randomized block design consisting of four treatments of sweet corn varieties, namely P1: Bonanza variety, P2: Ganebo variety, P3: Golden Boy variety, and F4: Exotic Pertiwi variety. The variables observed in this study were: (1) soil nutrient concentration variables and plant nutrient uptake (N and P) at 42 days after planting (dap), (2) growth variables included: plant height and number of leaves at 14, 28, and 42, and weight of wet and dry root and shoot at 42 dap, and (3) mycorrhizal population variables included: number of spores and percentage of root infection at 42 dap. Observational data were analyzed using analysis of variance followed by the Tukey’s HSD (Honestly Least Significant Difference) test at a significant level of 5%. The results showed that the Golden Boy variety with 25 t ha^-1 bioameliorant made from local raw materials gave the highest plant height, number of leaves, wet and dry biomass weight of roots and shoots. While the concentration of total N nutrients, available soil P, plant N and P nutrient uptake, as well as the number of spores, and the highest percentage of mycorrhizal colonization were obtained in the Bonanza F1.
