Soybean productivity can be increased by optimalizing marginal land (vertisols) to enlarge harvesting area. Application of biological fertilizer (Rhizobium and mycorrhizal inoculant) and organic fertilizer/manure (cow/goat/quail manure, and straw compost) are efforts to minimize external input to increase the use of marginal land to get high productivity. Application of organic manure that is enriched by straw compost and biological fertilizer (arbuscular mycorrhiza inoculation) could affect soybean growth and nutrient content on vertisols. Field experiment was done with two levels of mycorrhizal inoculation (without inoculation+10 g mycorrhizal inoculation per plant) and five levels of manure+straw compost (without manure; 10 t Ha-1 cow manure+5 t Ha-1 straw compost; 10 t Ha-1 cow manure+5 t Ha-1 straw compost; 10 t Ha-1 quail manure+5 t Ha-1 straw compost; 5 t Ha-1 straw compost). Application of mycorrhizal inoculation and manure treatment signifi cantly affected on dry mass parameter, while the trends on root length, chlorophyll content, seed wet weight, protein content, total nodules, mycorrhizal-root colonization, nitrogen uptake and phosphorus uptake were higher when soybean inoculated with mycorrhizal+ manure+straw compost. We concluded that mycorrhizal inoculation incorporated manure enriched straw compost can be applied on soybean low input farming systems to support Low External Input Sustainable Agriculture Programme/LEISA.
