| Popis: | Arbuscular mycorrhizal fungi (AMF) is a biological fertilizer that can function as an ameliorant which capable in increasing plant growth and yield of plants. Some vegetables such as kangkong (Ipomoea aquatica) and lettuce (Lactuca sativa) grown in Indonesia using substantial amount of NPK lettuce which has an impact on land degradation. The aim of this experiment were to determine whether AMF application technology can reduce the use of NPK application and can increase nutrient uptake of N, P, K, Fe, growth and yield of kangkong and lettuce grown on Andisols. This experiment was carried out at Screen House in Lembang District, West Java. This study used an experimental method with split plot design with two levels and three replications and applied on two types of vegetable plants. The main plot was AMF application (without and with AMF) and sub plot was various dosages of NPK (0, 25, 50, 75, 100%) of recommended dosages. Results of this study indicated that the application of AMF increased nutrient uptakes, growth and yield of vegetables. The AMF showed highest values at a dosages of 50% NPK, in terms of parameters of plant height, leaf number, N, P, K uptakes, chlorophyll contents, fresh root weights, root lengths and total mycorrhizal root lengths. Consequently, AMF was effective at low NPK dosages and was able to reduce the use of NPK dosages up to 50%. In conclusion, AMF has potential to be used in sustainable agriculture system |
