Abstract: Sweet corn farmers in Midang Village, Gunung Sari District, West Lombok Regency are currently still cultivating sweet corn using conventional cultivation technology with a relatively high input of inorganic fertilizers. This, if viewed from an economic point of view, is a waste and from an environmental point of view it is not environmentally friendly. Another problem is the production of sweet corn which is still low, not fresh and of low quality. Therefore, community service activities (CSA) on "Application of Bioameliorants Made from Local Raw Materials in Sweet Corn Plants"were tried to provide solutions to problems faced by farmers. The purpose of this CSA is to find out the yield of technology transfer for the use of bioameliorants made from local raw materials from the Faculty of Agriculture University of Mataram Team to the Farmers Group "Gapoktan Karya Usaha Bersama" in increasing knowledge about the use of bioameliorants and increasing sweet corn yields. The method used in implementing this CSA is the training method followed by practical work in the field by conducting demonstrations and active participatory action research. The demonstration plot method was carried out using a randomized block design using four varieties of sweet corn, namely V1: Bonanza variety, V2: Ganebo variety, V3: Golden Boy variety, and V4: Exotic Pertiwi variety. The result of the demonstration plot of the application of bioameliorants made from local raw materials at a dose of 25 t ha-1 on the Golden Boy variety gave the highest plant height and number of leaves. Meanwhile, the concentration of total N, soil available P, plant N and P nutrient uptake, number of spores and percentage of mycorrhizal colonization and the highest cob weight and wet biomass were obtained in the Bonanza F1 variety. With agricultural extension activities and discussions, farmers' understanding of the application of bioameliorants plus mycorrhizal biofertilizers in sweet corn cultivation increased by 90%.
