Abstract

Arbuscular mycorrhizal fungi are a group of fungi that can be symbiotic with many types of plants. Soil factors and plant species, affect the diversity of arbuscular mycorrhizal fungi. Likewise, differences in location and rhizosphere cause differences in the diversity of species and populations of AMF. In addition, not all AMF have the same morphological and physiological characteristics, therefore it is very important to know their identity. Coffee is a plant that has economic value and the potential for symbiosis with AMF. This study aimed to identify AMF in the rhizosphere of four varieties of Solok Radjo coffee plants in the Aia Cold area of ​​the Gumanti Valley, Solok, West Sumatra. Meanwhile, the stages of this research include: collecting and collecting data in the field, determining the location of the soil sample, analyzing soil properties in the laboratory, isolating AMF spores, and identifying AMF spores morphologically. The results showed that the diversity of AMF spores was found in 3 genera, namely Glomus sp., Acaulospora sp., and Gigaspora sp. The Kartika coffee variety has a higher AMF spore population than Sigararutang, Andongsari and Gayo.

Abstract

Rainfall variability, in terms of amount, distribution, and timing, can increase the risk of crop failure and reduce crop yields. This study aims to analyze CHIRPS (Climate Hazards Group InfraRed Precipitation with Stations) rainfall dynamics across several coastal areas of West Sumatra and to evaluate agroclimatic zones to assess the suitability of climate-adaptive cropping patterns. Monthly rainfall data for the period 1995-2024 were analyzed using the IDW interpolation method to produce rainfall distribution maps. This study also classified agroclimatic zones using Oldeman's classification to assess the suitability of cropping patterns. The analysis showed significant annual rainfall fluctuations, with high rainfall dominating the 1995-2014 period and a decline in the 2015-2024 period. Changes in monthly rainfall patterns, particularly the increase in rainfall from March to May during the 2015-2024 period, may affect planting times and irrigation management. The three regions studied (Padang Pariaman, Pariaman, and Padang) are in climate zone A1, with more than 9 consecutive wet months, allowing year-round rice cultivation. However, rainfall fluctuations require adjustments in planting timing and the selection of secondary crops that are more drought-resistant. The results of this study provide a stronger basis for agricultural planning that is more adaptive to climate change, with recommendations for adjustments to the planting calendar and irrigation management to ensure the sustainability of efficient and sustainable agricultural production.
