Abstract : The most significant barriers to boosting soil fertility and sweet corn plant growth are porous sandy soil and relatively low water retention capacity. This study aims to see how different types of ameliorants affect the absorption of NP nutrients and the growth of sweet corn (Zea mays L. var. saccharata) in sandy soil. From May to July 2023, the research was conducted at Moncok Karya, Pejeruk Karya Village, Ampenan District, Mataram City, Indonesia. The trial was set up using a randomized block design with five ameliorant treatments: PO (control), PA (rice husk charcoal rice), PK (compost), PS (cow manure), and PC (a mixture of rice husk charcoal, compost, and cow manure). The results showed that a 20 t ha-1 dose of ameliorant rice husk charcoal, compost, and cow dung resulted in N and P nutrient absorption, height, and number of leaves of maize plants at 14, 28, and 42 days after planting (DAP), the highest stover weight per plant, and mycorrhizal growth.
