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.

One of the limiting conditions for shallot plants to grow optimally is dry land conditions. Indigenous AMF application is one way to overcome this condition. This study aimed to determine the effect of indigenous AMF application on the morpho-physiological characters of two shallot varieties which are sensitive and tolerant to drought stress conditions. The study was carried out for 6 months on a wirehouse and laboratory scale. The Experiment used a completely randomized design with two factors. The first factor was varieties of shallots, i.e. Brebes (Sensitive) and Kuning (Tolerant) varieties of shallots. The second factor was the application of indigenous AMF which consisted of 5 levels i.e. Glomus sp1, Glomus sp2, Glomus sp3, a mixed those three isolates and control treatment (without application of AMF). The morpho-physiological observation parameters included header dry weight, root weight, and leaf proline content. From the observations, it can be concluded that under stressed conditions, the leaf proline content of the sensitive variety accumulated higher in the header than the tolerant variety, because the tolerant variety was better able to produce higher root and header weights when adapting than the sensitive. AMF inoculation did not show significant differences with the treatment without AMF inoculation on leaf proline. However, there was a tendency that inoculation of a mix of AMF isolates (Glomus sp1+Glomus sp2+ Glomus sp3) decrease the proline content in the leaves, both in sensitive and tolerant varieties so that plants are more resistant to drought stress.

Penyakit tanaman merupakan salah satu faktor penghambat untuk meningkatkan produksi tanaman. Hal ini juga menurunkan kuantitas dan kualitas produksi tanaman dan menyebabkan penurunan pendapatan petani, bahkan menyebabkan kehilangan hasil. Pengendalian penyakit tanaman harus dilakukan dengan tepat agar tidak memberikan dampak negatif terhadap lingkungan dan input yang rendah pula. Oleh karena itu, petani harus mengidentifikasi dan memastikan tingkat keparahan penyakit tanaman sebelum melakukan pengendalian. Tujuan dari penelitian ini adalah inventarisasi penyakit tanaman padi di Politeknik Pertanian Negeri Payakumbuh. Metode purposive sampling dan deskriptif digunakan dalam penelitian ini. Berdasarkan penelitian, beberapa penyakit yang ditemukan di lahan sawah yaitu bercak coklat (Helminthosporium oryzae), bercak coklat sempit (Cercospora oryzae), blas (Pyricularia grisea), hawar daun bakteri (Xanthomonas oryzae pv. oryzae), dan smut (Ustilagonoidea virens).

Biofertilizers contain N-fixing and P-solubilizing bacteria. The microbial population is dynamic and influenced by nutrient availability and storage temperature. Maintaining microbial populations requires appropriate carrier media to maximize microbial viability. The aim of the research is to determine the appropriate carrier material for the biofertilizer after storage based on the nutrient content and microbial population. The experiment utilized a completely randomized design with seven treatments and four replications, resulting in 28 experimental units. The treatments were as follows: B0 = Compost, B1 = Compost + Bacteria (Azotobacter and Pseudomonas fluorescens), B2 = Compost + Bacteria (Azotobacter + P. fluorescens) + Molasses, B3 = Compost + bacteria (Azotobacter + P. fluorescens) + CMC, B4 = Compost + bacteria (Azotobacter + P. fluorescens) + Arginine, B5 = Compost + bacteria (Azotobacter + P. fluorescens) + Sugar + CMC, and B6 = Compost + bacteria (Azotobacter + P. fluorescens) + Molasses + Arginine. The study results showed that the highest bacterial colonies were observed seven days after storage in treatment B2, reaching 156.33 CPU. The highest bacterial population growth in the first month was recorded in treatment B5; however, in months 2, 3, 4, and 5, treatment B2 exhibited the highest bacterial colony population. The pH remained more stable in treatments B2, B4, and B6. The highest nutrient content, including pH, N, P, K, and C/N ratio, was recorded in treatment B2, respectively, with values of 6.67, 2.49%, 2.04%, 1.77%, and 20.01. Findings in this study suggested the potential biofertilizer can be applied in the field to reduce dependence on chemical fertilizers to support sustainable agriculture.
