Abstract

The use of ex-limestone mining land as an alternative planting medium requires technological innovation to overcome nutrient limitations and unfavorable soil conditions. This study aims to determine the effect of Arbuscular Mycorrhizal Fungi (AMF) types and Yomari liquid organic fertilizer (POC) concentrations on the growth of oil palm (Elaeis guineensis Jacq.) seedlings at the pre-nursery stage in limestone mining waste soil. This experimental research was conducted in February - May 2025. The experiment was conducted at the Experimental Garden UPT, Faculty of Agriculture, and Plant Physiology Laboratory, Faculty of Agriculture, Andalas University, Padang. The design used was a factorial Completely Randomized Design (CRD) with two factors, namely the type of AMF (Glomus sp., Gigaspora sp., and a combination of Glomus sp. x Gigaspora sp.) and the concentration of Yomari POC (0; 0.5; 1.0; and 1.5 mL L⁻¹) which were each repeated three times, resulting in 36 experimental units. Each experimental unit consisted of 9 plants, with 5 samples for destructive observation and 4 samples for non-destructive observation, resulting in a total of 324 sample plants. The results showed no significant interaction between AMF types and POC concentrations on all growth parameters. However, individually, the AMF Glomus sp. type proved to be the most effective in supporting the growth of oil palm seedlings, as indicated by a high percentage of root colonization, increased phosphorus (P) uptake, and an increase in root length and volume. Meanwhile, the application of POC Yomari at a concentration of 1.0 mL L⁻¹ resulted in the best seedling growth, indicated by an increase in P uptake parameters, root length, and root volume. This indicates that the application of Glomus sp. AMF and POC Yomari at a dose of 1.0 mL L⁻¹ is effective in supporting the growth of oil palm seedlings in post-limestone mine soil media. In addition, the results of this study provide a scientific basis for the use of arbuscular mycorrhizal fungi and liquid organic fertilizer as a sustainable soil management strategy for post-mining land rehabilitation and improvement of oil palm nursery practices.

Abstract

This study aimed to determine the interaction between the best AMF types and doses, the best AMF types, and the best doses on the growth of cocoa seedlings planted in after-lime mine soil. The experimental study was conducted from February to June 2025. This research was conducted at the Wire House, Faculty of Agriculture, Andalas University, Padang City, West Sumatra, in the Seed Science and Technology Laboratory, Faculty of Agriculture, Andalas University. Root colonization observations were conducted at the Plant Physiology Laboratory, Faculty of Agriculture, Andalas University, Padang. The study used a factorial completely randomized design (CRD) consisting of two factors. The first factor was the type of AMF, with three levels: Glomus sp., Gigaspora sp., and Acaulospora sp. The second factor was the AMF dosage, with four levels: 0 g/seedling, 10 g/seedling, 20 g/seedling, and 30 g/seedling. Data were analyzed statistically using the F-test at a 5% significance level. If the calculated F-test was greater than the table F-test, the analysis was continued with Duncan's New Multiple Range Test (DNMRT) at a 5% significance level. The results of this study indicate that there was no interaction between the type and dosage of AMF on the growth of cocoa seedlings planted in ex-lime mining soil. The Glomus sp. AMF was the best AMF for enhancing the growth of cocoa seedlings planted in ex-lime mining soil. Meanwhile, the AMF dosage of 30 g/seedling was the best for enhancing the growth of cocoa seedlings planted in ex-lime mining soil.

Abstract

Maize is a light-dependent crop, but new varieties have been developed that can tolerate shade. This allows farmers to grow maize as an intercrop between coconut trees, making more efficient use of their land. Farmers can also intercrop with legume plants, which provide additional nitrogen through Rhizobium bacteria, leading to increased maize productivity. The aim of this study was to obtain the best intercropping pattern for maize and soybeans under coconut trees that results high yields in maize. The study was conducted in Padang Pariaman Regency of West Sumatra, at an altitude of approximately 150 meters, from February to July 2022. The experimental design was a Split Plot Design with Randomized Block Design, consisting of three main plot levels (planting time) and four subplot levels (planting model). The results of the study indicate that intercropping maize and soybeans under coconut trees has no effect on the weight of maize cobs, but there is a positive correlation between ear weight, cob length, cob diameter, number of rows per cob, and the weight of 1000 maize seeds.

Abstract

The quality of the Garlic seed bulbs needs to be improved by seed propagation through tissue culture techniques to get uniform and big cloves. Utilizing the suitable color spectrum of light is one way to stimulate plant morphogenesis. This study aimed to identify the influence of light color and obtain the best color in the morphogenesis of garlic callus explants. This research was carried out from June to September 2022 at the Tissue Culture Laboratory, Faculty of Agriculture, Universitas Andalas. This study used a completely randomized design with three treatment levels: red, blue, and white. The F test analyzed observational data at a 5% level, followed by Duncan's multiple Range Test (DNMRT) at a 5% level. The results showed light color influences embryogenic callus formation and shoot formation from garlic callus explants. Blue light is better than red and white light in inducing embryogenic callus, increasing the rate of explants forming shoots but giving no significant difference in the length of the shoot.

Abstract

One of the causes of the low productivity of rice grown on peat soils was the high levels of of toxic phenolic compounds in the soil. Development of tolerant rice varieties is one of strategies to grow rice on peat soils. The aims of this research were to select rice varieties tolerant to peat soils and to study the correlation between the plant phenolic acid content with plant tolerance to peat soil. This research was conducted at the Seed Farm Centre Lubuk Minturun, Padang from February to July 2009. The research consisted of two experiments i.e. in peat soil and in mineral soil. The experiments used a completely randomized design using 21 varieties of rice as treatments which were replicated four times. The results showed that there were nine rice varieties categorized as tolerant to peat soil. These tolerant varieties showed higher stress tolerance index (STI), demonstrated by a high level of phenolic acids (coumaric, syringic, and ferulic) in the plant tissues. The STI value had positive correlation with the content of plant phenolic acids, thus the level of plant phenolic acids can be used as an indicator to determine tolerant rice varieties in peat soils.

Abstract

Rice production in acidic soils is often limited by leaf blast disease and iron (Fe) toxicity. This study aimed to identify local rice genotypes cultivated in Solok Selatan that are tolerant to leaf blast disease and iron stresses at the vegetative stage. Ten rice genotypes, consisting of six local genotypes and four comparison genotypes, were tested under three levels of soil Fe content (11,393.12 ppm, 16,781.83 ppm, and 18,699.25 ppm) using a Completely Randomized Design with three replications. The observed variables were number of tillers, root length, leaf blast score, and Fe toxicity score. The results showed that Batang Piaman had the highest number of tillers (72.00), while Guliang Tandai Merah and Batu Hampar Putih had the longest roots (50.67 cm and 49.78 cm). Guliang Tandai Merah had the lowest leaf blast score (2.89), and together with Batang Piaman, also showed low Fe toxicity scores (3.56 and 3.22), indicating good tolerance. In contrast, Simauang and IR64 were the most susceptible against iron toxicity compared to other rice genotypes. Principal Component Analysis (PCA) explained 81.80% of the total variation and placed Batang Piaman and Cilamaya Muncul in the quadrant of high tolerance and good agronomic traits. Cluster analysis grouped the genotypes into three major clusters, with Guliang Tandai Merah and Batu Hampar Putih forming a distinct group based on strong root traits. Although no genotype was completely resistant, Batang Piaman and Guliang Tandai Merah are promising candidates for breeding programs targeting leaf blast and Fe toxicity tolerance.
