Abstract

The Influence of Indigenous Trichoderma sp. Inoculation against Clubroot and the Growth of Cabbages (Brassica oleracea L.) The Cabbage (Brassica oleracea L.) is a plant that contains many vitamins and minerals needed by human. The problem which often experienced by cabbage farmers is clubroot deseases that caused by pathogenic Plasmodiophora brassicae Worr. Eco-friendly controls are needed so as not to adversely affect ecosystems by using natural enemies of the pathogen such as Trichoderma sp. The purpose of this research was to obtain the type Trichoderma sp. which effectively suppress clubroot and increase the growth of cabbage plants. The results showed that the most effective isolate was isolate from zucchini plant (Cucurbita pepo L.) rhizosphere (T1), followed by tomato plant (Lycopersicon esculentum L.) rhizosphere (T2), romana plant (Lactuca sativa L. var. longifolia) rhizosphere (T4), and from the spinach plant (Spinacia oleracea L.) rhizosphere (T9). The isolates were able to decrease clubroot and promote cabbage plant growth as well.

ABSTRACT Vesicular Arbuscular Mycorrhizae (VAM) Identification of Chilli (Capsicum annuum L.) and Tomato (Solanum lycopersicum L.) Rhizosphere and Its Spore Multiplication in Zeolite Media Various attempts have been made to increase the production of chilli and tomato plants by farmers, including by using  inorganic fertilizer application on and on going basis. Considering potential problems that may occured due to inorganic fertilizer use, aplication of  biological fertilizer which one of them is containing vesicular arbuscular mycorrhizae (VAM) could be expected to assist the growth of chilli and tomato in more naturally manner. This study was aimed to determine genus and species of VAM in chilli and tomato rhizosphere, its colonization in root tissue, and to examine zeolite media compatibility with corn as a symbiont. Based on the results of the study, it was found four species namely Acaulospora fofeata, A. colombiana, A. Laevis, and Glomus ambisporum in chilli and four species in tomato that were identified as A. fofeata, A. colombiana, Scutellospora calospora, and G. ambisporum. Colonization were found in roots of chilli, tomato, and corn indicated by symbiotic structures arbuscules, vesicles, and inner spores. Zeolite media with corn as symbiotic plant is considered suitable for VAM spore propagation. Keywords: rhizosphere, Acaulospora fofeata, zeolite, inner spore
