Abstract

The use of biofertilizers is part of an environmentally friendly plant cultivation. In order to analyze the effect of soaking seeds with several types of biofertilizers on seedling growth and damping off disease in tomatoes, a greenhouse experiment has been carried out using biofertilizers and the fungicide Propineb as control treatment. The biofertilizers used were mixed biofertilizer (BION-UP), Consortium isolates of tomato rhizosphere bacteria (CITRB), consortium of Azotobacter chrococcum and Trichoderma harzianum (Azoto-Tricho). The results showed that soaking tomato seeds in bioagens solution increased plant height, number of petioles, fresh weight and dry weight of plants, as well as suppressed damping off disease in tomato nursery. The CITRB biofertilizer has a better effect on plant growth and diseases suppression than another biofertilizers and Propineb fungicide. CITRB enable to increase plant height by 49.97%, number of petioles by 60.00%, plant fresh weight by 107.23%, dry weight of plants by 129.41%, and suppress damping off disease by 56.67%. BION-UP, CITRB and Azoto-Tricho were able to suppress damping off disease by 22.22%, 27.78% and 16.67% respectively.  The ability of all biofertilizer to suppress damping off disease incidence were better than Propineb fungicide.

Abstract

The growth of nutmeg seeds requires adequate nutrition by mechanism of bacteria activity associated with roots and leaves. The aim of study was to determine the effect of application of bacillus strain consortium biofertilizer on nutmeg seedlings. The experiment was arranged by using completely randomized design with 0% of PBH as control, and 0.15% and 0,30% of PBH concentration by spraying to leaves and by pouring in the soil around the stem, respectivelly. The results showed that the application of 0.15% and 0.30% of PBH concentration has significant effect in plant height, shoot dry weight, dry weight root and plant dry weight, but not at the number of root, root length, stem diameter, and the ratio of shoot and root dry weight of nutmeg seedlings after four month planting in the polybag. The concentration of PBH 0.30% has a greater influence on the nutmeg seed growth, and can be a solution to increasee  seed growth.

Abstract

Seedling fall disease caused by the fungus Rhizoctonia solani is one of the limiting factors in the cultivation of mustard plants. This pathogen can attack plants in the nursery as well as after the plants in the field. The aim of this study was to determine the effect of using biological fertilizers Azoto-Trico and KIBPF with different application time intervals on the development of seedling fall disease and the growth of mustard in the nursery. The study used Azoto-Tricho and KIBPF biological fertilizers with application intervals of 2 days, 4 days and 6 days. The results showed that the application of biological fertilizers Azoto-Tricho and KIBPF with different application time intervals had an effect on controlling seedling fall disease and increasing plant height and plant fresh weight. The application of Azoto-Tricho biofertilizer and KIBPF if applied at intervals of 2 days or 4 days or 6 days had the same ability to control seedling fall disease and increase plant height and fresh weight of mustard plants in nurseries.

Abstract

Azotobacter is Plant Growth Promoting Rhizobacteria through the mechanism of nitrogen fixation and phytohormon production but this rhizobacteria has a role to control plant diseases. The objective of experiment was to evaluate the activity of Azotobacter as biofertilizers as well as biocontrol on long bean cultivation in damping off endemic land in Ambon city, Maluku Province. The field experiment was arranged in completely randomized block design. Inoculation of long bean by Azotobacter has been done by seed inoculation, soil inoculation before planting, and plant inoculation. Plants treated with Azotobacter received fertilizer NPK of ¾ or ½ dosage recommendation while control plants were received 100% NPK. Research showed that no differences between yield of long bean inoculated with Azotobacter sp +reduced doses of NPK with that of control plants. Any application method of Azotobacter inoculation lowered damping off diseases incidence significantly until 10 days after planting, but no effect of inoculation on late blight at 21 days after planting. This study confirmed that Azotobacter has dual activity to reduce the dose of NPK fertilizer and control damping off.

Abstract

The sago plant is a staple food for the people of Maluku and Papua and has many benefits and advantages to continue to be developed. A group of phylloplane microbes grow and spread on the surface of the leaves. The objective study is to find isolates of phylloplane bacteria from sago accession Makanaru and determine the inhibition of these bacteria against the growth of Rhizoctonia solani Kuhn. Sampling of sago plants (upper, middle, and lower leaves) was conducted in Negeri Seith, Leihitu District, Central Maluku Regency. Based on the isolation results, 21 isolates of phylloplanes bacteria were obtained and ready for further testing. From the results of hypersensitive test selection, 14 non-pathogenic isolates of phylloplane bacteria were obtained. Furthermore, tested the inhibitory power of phylloplane bacteria in suppressing the growth of the fungus, 3 phylloplane bacteria isolates were obtained with strong inhibitory, namely DA3.3, DT3.2, DT3.1 followed by 3 isolates DB4, DB4.2, and DB4.4 (medium inhibitory) which have the potential to be developed as biological agents.
