Currently looking for alternative approaches to crop production which would be in accord with sustainable development. The present thesis was aimed on testing of organic cultivation of tomato (Solanum lycopersicum L.) and leek (Allium porrum L.) by using amendment with organic maize biomass (Zea mays L.), mycorrhizal fungi and saprotrophic fungi. The effects of different combinations of microbial inoculations on nitrogen uptake, plant growth and yield were investigated in greenhouse conditions. Supplied 15 N-labelled organic matter was separated from the root system by a nylon mesh which permitted only fungal hyphae to pass through but not plant roots. In the first year experiments the treatments differed in the presence or absence of three factors: organic matter, saprotrophic fungus Agrocybe sp. and mycorrhizal fungus Glomus mosseae (Nicolaj & Gerd.) Gerd. & Trappe. Plant inoculation with Agrocybe sp. alone or together with G. mosseae increased plant growth of tomato in the presence of organic matter. Tomato yield were not increased significantly. Shoot dry weight of leek increased when plants were treated with mycorrhizal fungus G. mosseae and organic matter. Microbial inoculation did not influence nitrogen (15 N) uptake from the organic source. In following experiments, all treatments contained...
