Abstract

Coffee is one of the leading commodities in Indonesia. These plants are usually cultivated with agroforestry systems. The agroforestry system was chosen because it can increase crop productivity. But there are still many factors that can affect productivity such as Arbuscular Mycorrhizal Fungi (AMF). This study aims to analyze the relationship between the number of spores, the percentage of colonization, and the diversity of AMF. The result showed that the highest percentage of colonization and the number of spores found in land 3. The agroforestry component affects the presence of AMF. The percentage of colonization and the number of spores from AMF is generally directly proportional. Diversity of AMF spores morphological type, among others Glomus has 9 forms, Acaulospora has 5 forms, Dentiscutata has 5 forms, Entrophospora has 4 forms, and Gigaspora has 1 form. Keywords: Acaulospora, Dentiscutata, Entrophospora, Gigaspora, Glomus

Abstract

Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil) is a forest plant that can replace sengon (Falcataria moluccana) because it has advantages. The demand for red jabon wood is increasing, but the cultivation of red jabon is still constrained by the attack of pathogens that cause leaf disease. The attack of these pathogens can cause damage and death of seedlings so that it can be economically detrimental. The aim of this study was to identify the pathogens that cause disease in red Jabon. The method used is the Postulate Koch method, which starts from sampling red leaves with leaf disease symptoms, isolation, inoculation and analysis of disease incidence, re-isolation, and identification. Based on the identification results found as many as 2 pathogenic fungi that cause leaf spot disease, namely Pestalotia sp. and Rhizoctonia sp. In addition, 6 pathogenic fungi were found that cause blight, namely Lasiodiplodia theobromae, Fusarium sp., Colletrotrichum sp., Marssonina sp., Gloeosporium sp. 1, Gloeosporium sp. 2. Keywords: identification, percentage of disease incidence, Postulat Koch, red jabon

Abstract

Java kenanga or kenanga (Cananga odorata f. macrophylla) is a tropical and sub-tropical tree species that grows naturally in Indonesia and produces essential oil. This species has been cultivated in the past by community in Indonesia, mainly on their yard. The population of kenanga has decreased significantly, but in Blitar district the community is still doing cultivating the species although in a small scale. The purpose of this research is to observe the cultivation efforts by the community and also kenanga flower production in Blitar district. This research was conducted by interviewing farmers and observation of kenanga trees in the field. The results showed that cultivation efforts being made to improve the production of kenanga flower is by pruning, fertilizing, flowering routine and retrieval or emoval of kenanga fruit. The average kananga flower production reached 381 kg / year / tree in the age group above 11 years. Factors that affect flower production were tree age (years), total tree height (m), diameter at breast height (cm) and the width tree canopy (m2). The most significant factors affecting flower production were tree diameter and width of tree canopy. Cultivation efforts being made to improve the production of kenanga flower is by pruning, fertilizing, flowering routine and retrieval or removal of kenanga fruit.

Abstract

Kesambi (Schleichera oleosa (Lour.) Merr.) is a host plant that becomes priority in lac culture in Indonesia. Shellac is one of the non-timber forest product commodities, which is potential to be one of foreign exchange sources. World demand of shellac is increasing throughout the year so that the improvement of shellac productivity is required to fulfill the demand. One of the alternatives is implementing the fertilization due to host plant quality improvement considering that host plant is the source of nutrient of shellac. The activity of fertilization aims to understand the effect of fertilization dosage to the improvement of the branch length as well as productivity of shellac in KPH Probolinggo. The greatest average value of branch length during three and six months, respectively were 66.48 cm and 83.24 cm. While, the greatest average value of shellac productivity was 84.29 g. The treatment of fertilization in different dosage to the kesambi (Schleichera oleosa (Lour.) Merr.) was not give significant effect to the length of branch as well as shellac productivity.
