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

Leafy vegetables contributes to the inflation rate in Ambon City due to low productivity in rainy season. Some vegetables are imported from other islands while importantvegetables such as local petsai (Brassica chinensis L.) and chili (Capsicum annum L.) are cultivated in low nitrogen soil, Entisols. Lack of nitrogen could be overcome by using inorganic fertilizeras well as biofertilzer. The soil can be inoculated with rhizobacteria, such as Azotobacter, to increase  the nitrogen uptake and improve the quality of vegetables. This research was conducted to isolate and select Azotobacter from rhizosphere of vegetables and to examine the effect of Azotobacter inoculation on chili-seedling growth and nitrogen uptake by using bioassay method. Azotobacter sp. was isolated in nitrogen-free Ashby’s Media. The bioassay was held in the green house with randomized block design experiment, which examined the combination of isolates and population of Azotobacter sp. on chili. Two best isolates which was selected based on pH, nitrogen content and cell viability were s2a10 (from petsai's rhizosphere) and c2a9 (from chili’s rhizosphere). Bioassay showed that Azotobacter inoculation followed by reduced NPK fertilizer doses had no effect on transplant dry weight and nitrogen uptake. All Azotobacter 8 -1inoculation except  10 CFU mL s2a10 maintain soil nitrogen although Azotobacter population in soil was slightly reduced. This showed that Azotobacter sp. potentially reduce the use of inorganic biofertilizer.

Abstract

Mercury (Hg) is commonly utilized in artisanal gold mining on Buru Island; the Hg-contaminated tailing possibly contaminates the agricultural land nearby. In general, tailings contain very low organic carbon and plant nutrients but are high in mercury and have extreme soil acidity. The objective of this study was to observe the growth of various legume cover crops (LCC) and the change of Hg in tailing inoculated with Azotobacter-Trichoderma. The field trial was conducted on Buru Island of Maluku by using a split-plot design with three replications. The main plot was LCC species, composed of Centrosema pubescens (CP), Mucuna sp. (MC), and Crotalaria sp. (CR); the subplots were microbial inoculants composed of two formulations of Azotobacter-Trochoderma inoculants. The results showed that the Mucuna sp. and consortia Azotobacter-Trichoderma (2:1) had the highest survival rate in the tailings and Hg uptake by 8.83 mg kg-1 per plant. Consortia Azotobacter-Trichoderma inoculant with the composition of 2:1 (v:v) was able to increase soil pH, total bacterial population, LCC biomass, and Hg uptake by LCC plants. The highest Hg removal effectivity was observed in the plot treated with Crotalaria sp. and in a plot with Azotobacter-Trichoderma (2:1), which was 34.0% and 33.6%, respectively.

Abstract

Mikroba tanah dapat digunakan sebagai input pertanian. Rizobakteri Azotobacter pemfiksasi nitrogen menjaga ketersediaan unsur hara nitrogen dan pertumbuhan tanaman sedangkan Trichoderma mampu menurunkan kejadian penyakit tular tanah melalui aktivitas antagonistik. Percobaan pot ini bertujuan untuk mendapatkan dosis dan waktu aplikasi inokulan Azotobacter- Trichoderma yang dapat meningkatkan ketersediaan nitrogen tanah, pertumbuhan dan hasil tanaman cabai (Capsicum annuum L.). Bibit cabai ditanam di tanah dengan kesuburan rendah yang dicampur dengan pupuk kotoran sapi. Rancangan percobaan adalah rancangan petak terbagai yang menguji empat taraf dosis inokulan dan tiga waktu aplikasi. Hasil percobaan memperlihatkan bahwa tidak ada pengaruh agen biologi terhadap tinggi tanaman pada tiga dan enam minggu setelah tanam. Inokulasi 7,5 g pot-1 inokulan padat Azoto-Tricho pada saat tanam secara signifikan meningkatkan kadar NO3 - tanah jika diikuti dengan penyiraman inokulan cair Azotobacter ke tanah pada 10 hari setelah tanam. Inokulan padat Azoto-Tricho meningkatkan hasil tanaman. Hasil tertinggi, 290 g per tanaman diperoleh dari tanaman yang diberi 7,5 g Azoto-Tricho pada saat tanam diikuti aplikasi inokulan cair Azotobacter. Percobaan pot ini menjelaskan bahwa inokulan padat Azotobacter-Trichoderma berpotensi untuk digunakan sebagai agen hayati pada produksi cabai.
