“…If the soil water content contains enough water, it will stimulate the spores to germinate so that the number of spores decreases. Elita et al, (2018) reported that the application of AMF to rice cultivation using the SRI method (System of Rice Intensification Method) showed a high level of root colonization and spore count. In Table 2, it can be seen that the highest number of spores on shallot land with the lowest water content is 10.26%.…”

Differences in location and rhizosphere cause differences in species diversity and population of Arbuscular Mycorrhizal Fungi (AMF). In addition, not all AMF have the same morphological and physiological characteristics, therefore it is very important to know their identity. This study aims to determine the presence and number of spores as well as to determine the morphological characteristics of AMF originating from the rhizosphere of several horticultural crops in the agricultural land of Payakumbuh State Agricultural Polytechnic. The method used in this research is descriptive exploratory method by means of purposive sampling for soil sampling. While the stages of this research include: taking and collecting data in the field, determining the point of location for soil sampling, taking soil samples, analyzing soil properties in the laboratory, isolating AMF spores and identifying AMF spores morphologically. The conclusions of this study are 1) The population of AMF spores in horticultural land is high. The highest spore population was found in soil samples of the root area of shallot plants (556 spores per 10 g of soil), while the lowest number of spores was in soil samples of eggplant root areas (271 spores per 10 g of soil), 2) AMF exploration in several horticultural crops in the agricultural land of the Payakumbuh State Agricultural Polytechnic, based on morphological identification (shape, color and size), the AMF found consisted of three genera, namely Glomus sp, Gigaspora sp, and Scutelospora sp.

Peranan mikroba meningkatkan hasil padi metode SRI beragam dipengaruhi jenis, kombinasi mikroorganisme, daya adaptasi, dan teknik aplikasi. Hasil penelitian menunjukkan aplikasi mikroba indigenous mampu meningkatkan hasil tanaman padi metode SRI. Jenis mikroba tanah jamur Trichoderma spp. umumnya banyak ditemukan merupakan jamur tanah biasanya ditemukan pada rizosfer tanaman, termasuk rizosfer tanaman padi. Tujuan penelitian untuk mengetahui jenis Trichoderma spp. indigenous secara makroskopis dan molekuler asal rizosfer beberapa varietas padi di Kabupaten Lima Puluh Kota dan Kota Payakumbuh. Metode yang digunakan adalah eksplorasi, isolasi dan karakterisasi. Eksplorasi Trichoderma spp. indigenous diambil dari tanah rizosfer padi di Kabupaten Lima Puluh Kota dan Kota Payakumbuh. Isolasi dan karakterisasi jamur Trichoderma spp. indigenous dilakukan di laboratorium Mikrobiologi Politeknik Pertanian Negeri Payakumbuh dan teknik molekuler dengan Amplifikasi PCR di Balai Penelitian Tanaman Buah Tropika di Solok. Hasil penelitian diperoleh isolat T1-KK (Kuriak Kuning), T2-PW (Pandan Wangi), T3- J (Junjuang) ketiganya asal Kabupaten Lima Puluh Kota, T4- S (Sokan), T5-KM (Ketan Merah), T6-SB (Siliah Baganti) asal Kota Payakumbuh. Hasil amplifikasi PCR diperoleh jenis isolat Trichoderma spp dari masing-masing isolat tersebut adalah T1-KK jenis jamur Trichoderma asperellum, T2-PW jenis jamur Trichoderma harzianum dan Trichoderma asperellum, T3-J jenis jamur Trichoderma harzianum dan Trichoderma asperellum, T4-S jenis jamur Thichoderma asperellum, T5-KM jenis jamur Trichoderma harzianum dan Trichoderma asperellum, dan T6-SB jenis jamur Trichoderma harzianum dan Trichoderma asperellum.

“…The use of Trichoderma harzianum and Pseudomonas fluorescens which are present in Bioorganic Plus compost as microbial inoculants for rice plants grown using SRI method results in a higher availability of nutrients and nutrient uptake than in conventional systems, and has been shown to increase rice production up to 229% (Erlinda et al, 2019). Application of microbial inoculants containing Arbuscular Mycorrhizal Fungi (AMF) has also increased SRI rice production to 13.86 t ha -1 (Elita et al, 2018a). The availability of P in the soil and absorption of P from root to leaf increases significantly as a result of microbial inoculation.…”

The System of Rice Intensification (SRI) operates under aerobic conditions so that helpful microbes are active and abundant. Effective N-fixing rhizobacteria and indigenous phosphate solubilizers Azotobacter and Pseudomonas grow well in the organic compost Bioorganic because it resembles their natural habitat. The purpose of this research is to find out the right dose of Bioorganic fertilizer and the most N and P doses needed to optimize the SRI method of rice crop production. This research uses a factorial randomized block design. The first factor is Bioorganic fertilizer dosage (1, 3, and 6) t ha-1. The second factor is the dose of N and P fertilizers to use (0, 25, 50, and 75)% of the recommended dosage. The results of this study inform you about Bioorganic fertilizers containing Azotobacter and Pseudomonas fluorescens indigenous. Azotobacter bacteria produce the availability of nutrients N, which functions as Plant Growth Promoting Rhizobacteria (PGPR), these bacteria quickly colonize the root system, regulate hormonal balance, nutrition, and encourage resistance to pathogens. Pseudomonas fluorescens bacteria acts as a provider of phosphorus and nutrients in the generative phase. Both of these microbes have a role in SRI method of rice plant metabolism to increase vegetative and generative growth of rice plants with SRI method with production reaching production of 8.80 t ha-1 in B2 (3 t ha-1) and N2P2 (50%) with the production of 9.21 t ha-1, so the use of inorganic fertilizers is more efficient. Rice soil nutrient status increased pH from slightly acidic to neutral, C-organic increased from 1.27% (low) to 9.30-10.68% (high), N total from 0.13% (low) to 0.45-0.58% (high), P- available from 13.0 ppm reaching 18.0-20.0 ppm (moderate), the Bioorganic application has not been able to increase the C: N, CEC value and base saturation. Nutrient uptake of N and P on the leaves of rice plants is better at dose B2. Bioorganic applications increase the nutrient content of paddy soils planted with the SRI method compared to initial soil nutrient analysis.
