Abstract

The experiment was conducted at the Laboratory of Plant Pathology Faculty of Agriculture, Syiah Kuala University from February to June 2013. The purpose of study was to evaluate the survival of T. harzianum and T. virens after cohabiting with soil borne pathogenic fungi (Fusarium sp, Rhigidoporus sp, and Sclerotium sp) as well as the type of interaction. Trichoderma fungi and fungal pathogens were grown on PDA in vitro, and then observed their growth after being reisolated on 3 different growth zones. The results showed that T. harzianum and T. virens  growing with Fusarium sp were capable to grow over the space. It was evident from the results of reinoculation on a petridish B (border zone) and C (zone Trichoderma) colonies, that T. harzianum and T. virens regrew, while the pathogens were not able to regrow. When cohabiting with Sclerotium sp and Rhigidoporus sp, antagonistic fungus regrew after reisolation but pathogens also grew on Petridis B (border zone). It indicates that on the contact area (petri dish B), Sclerotium sp and Rhigidoporus sp conduct defense over the competition. Regrowth of fungal pathogens on contact area (border) indicates that the fungus has a high level of competition. Antagonist agents such as T. virens and T. harzianum were able to survive and regrow after cohabiting with fungal pathogens and showed type A interaction (against Fusarium sp), while cohabiting with Sclerotium sp and Rhigidoporus sp showed the type B interaction.

Abstract

Use of Guano and Fertilizer NPK to Improve Quality of Subsoil Media and Growth of Oil Palm SeedlingABSTRACT. Utilization of subsoil as a growing medium for the nursery is a challenge to replace the role of topsoil as media for oil palm nurseries mainly on main nursery. This research was aimed at studying the effects of organic Guano and inorganic NPK fertilizer on oil palm seedling growth on sub soil growing media. The experiment was conducted in a pot, arranged in a randomized complete block design (RCBD), factorial 4x3 with 3 replicates. There were two factors examined, 1) guano dose consisting of four levels, namely: 0 kg, 0.5 kg, 1.0 kg and 1.5 kg/polybags and 2) inorganic fertilizers NPK consisting of three levels, namely: 0, 15, and 30 g/polybags. The results showed that subsoil can be used for growing media with applications of fertilizer Guano and inorganic NPK fertilizer. Guano and NPK fertilizer affected several soil chemical properties, i.e. increase in soil pH, available total C and N and P, and cation exchange capacity (CEC) and affected growth of oil palm seedling at age 16 weeks after planting. The best combination for the best seedling growth was obtained at 1.5 kg Guano + 30 kg NPK

Abstract

The utilization of biocontrol agents as an alternative to synthetic pesticides becomes widespread as the increase of awareness to negative effects of synthetic pesticides. The objectives of this research were to isolate rhizobacteria from tomato plant rhizosphere and to characterize effective rhizobacteria isolates to deter growth of Phytopthora capsici colony. The rhizobacteria was isolated from healthy tomato plant rhizosphere, and then antagonism nature to pathogen was evaluated by double culture method. Deterrent ability of the rhizobacteria was measured based on resistance zone formed due to the presence of the biocontrol agents. Among 57 isolates, 18 were potential for further evaluation. Deterrent ability test of the 18 isolates resulted in 3 isolates which were very promising to be developed as biocontrol agents to control seed borne pathogens. They were RBBM36, RBBM18 and RBBM35.

Abstract

            A study to determine a right concentration of organic fertilizer Super Nasa and type of organic mulches on growth and yield of soybeans has been conducted. The experiment used a factorial randomized complete block design 4 x 3 with 3 replications. Factors studied were concentrations of organic fertilizer Super Nasa, consisting of 4 levels: 0, 5, 10, 15 g/L of water and types of organic mulches, consisting of three levels: printing newspaper, bagasse, and paddy stalk. Results showed that the concentrations of organic fertilizer Super Nasa exerted highly significant effects on dried grain weight per plot netto and dried seed weight per hectare and exerted a significant effect on plant height 45 day after planting, but exerted no significant effect on other variables. The best growth and yield of soybean were found at a concentration of organic fertilizers Super Nasa 10 g/L of water. Types of organic mulches did not affect all variables observed. However, Soybean yield was apparently better at printing newspaper. There was no significant interaction between concentration of organic fertilizer Super Nasa and types of organic mulches on all growth and yield variables observed.

Abstract

The research objective was to determine the effect of Trichoderma species and spraying frequency on the intensity of  black pod disease (Phytophthora palmivora) and cocoa yield. This study was conducted in farmer's field in The East Aceh District, at June to Desember 2014. The choice of location was based on a history of the cocoa pod disease in the previous period or the location was endemic. The research was arranged in randomized block design non factorial, consisted of 10 treatments and 4 replications, i.e : A = control, B (T. harzianum + spraying frequency of 1 times), C (T. harzianum + spraying frequency of  2 times), D (T. harzianum + spraying frequency of 3 times), E (T. viren + spraying frequency of 1 times), F (T. viren + spraying frequency of 2 times), G (T. viren + spraying frequency of 3 times), H (T. asperellum + spraying frequency of 1 times), I (T. asperellum + spraying frequency of 2 times), J (T. asperellum + spraying frequency of 3 times). Each treatment consisted of 5 plants, the number of plant are 200 plants. At each plant is set 10 cacao pod as samples for observation of disease intensity. The results of the research showed that the the lowest intensity of black pod disease due to the combination treatment of Trichoderma species and spraying on 2 and 3 months after application frequency found in treatment D (T. harzianum + 3 times spraying  frequency) was 12.50 % and 13.13 %. The highest cocoa fruit yield found in treatment D (T. harzianum + 3 times spraying frequency) was 45.75 kg and the lowest found in treatment A (without Trichoderma / control) was 27.02 kg.

Abstract

            Response of plant on agroinputs such as organic fertilizer is different, depending on cultivar. Nutrient composition of organic fertilizer is also varied from one to another. The cultivar of Kipas Putih and Anjasmara were studied. The growth and yield of soybean were significantly affected by cultivar and organic fertilizer,  composted from manure and green manure using EM-4.  The growth and yield of Kipas Putih were significantly better than those of Anjasmara.  Fertilization with 12.5 ton/ha of organic matter also increased growth and yield of soybean.
