Abstract

This study aims to determine the diversity accessions of Siak Regency’s local rice. The study was conducted for six months, from May to October 2018 at Experimental Garden of Agriculture Faculty, Riau University. This study used descriptive qualitative analysis method based on agronomic and morphological characters, as well as characterization activities on 21 local rice accessions. There are 10 morphological characters with low diversity, such as the surface, leaf surface, leaf tongue shape, leaf neck color, leaf ear color, leaf book color, leaf tongue color, grain tip color and the color of the pistil. There are five morphological characters with rather low diversity, such as the presence of lemmapalea hair, the color of stem segments, the color of leaf blades, panicle shaft and vigor. There are five morphological characters with quite high diversity, such as yellowing of leaves, panicle discharge, panicle type, secondary panicle branches and leaf midrib color also three morphological characters with high diversity, such as lemmapalea color, grain tip fur and grain tip fur color. While the agronomic character with a rather low diversity is vigor and there are three characters with quite high diversity, such as the stiffness of stem, yellowing of leaves and panicle discharge. Keywords: Agronomy, diversity, local rice, morphology.

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

Soybean (Glycine max. L) is a strategic commodity that plays a major role in providing nutritious food. One effort to increase soybean production is through the use of superior varieties. Dega-1 is a soybean variety that is very sensitive to drought so that it is necessary to develop soybeans cultivated in dry land which can be attempted through mutation breeding. The purpose of this study was to determine the duration of ultraviolet C light irradiation that can produce mutants and to obtain putative drought-tolerant mutants through ultraviolet C light mutation induction and in vitro selection (PEG 25%). This study was conducted from April to July 2024 at the Tissue Culture Laboratory, Faculty of Agriculture, Andalas University. This study was arranged in a Randomized Block Design with treatment duration of UV C light irradiation λ 254 nm with 10 treatment levels including no radiation, 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, 90 minutes, 105 minutes, 120 minutes, and 135 minutes. Each treatment consisted of 5 groups. The observation data were analyzed using simple statistical analysis using the mean and standard deviation calculations. The results showed that the highest percentage of putative drought-tolerant soybean mutants (PEG 6000 25%) was produced by 45 minutes of UV C irradiation, namely 3.33%. These mutants emerged from blackish-brown callus and developed into yellow callus and also regenerated into somatic embryos.

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

Shallots (Allium cepa L.) is one of the important vegetable commodities that many people need as a seasoning for cooking. Shallot production in South Sulawesi region experienced a significant decline from 2021 to 2022, namely from 183.210 tons to 175,160 tons (BPS 2023). In the cultivation process, shallots are susceptible to pest attacks. One of the main pests that causes a decrease in shallot productivity is the onion caterpillar (Spodoptera exigua Hbn.). This research will be carried out in Potokullin Village, Buntu Batu District, Enrekang Regency, South Sulawesi and BRMP Laboratory (Agricultural Assembly and Modernization Agency), in March 2025-July 2025. This research activity uses a random group design consisting of 5 treatments, namely without refugia (P0) as a control, marigold (P1), zinnia (P2), virgin footprint (P3), a combination of marigold plants, zinnia and virgin footprint (P4). Each treatment is repeated 4 times and each repetition consists of 9 plants so that the number of observation units is 180 plants. The results showed that treatment without refugia (P0) showed the highest density of caterpillar population (0.58) and was markedly different from Zinnia refugia treatment (P2) which had the lowest density (0.28). Meanwhile, the results of the attack intensity shows that treatment without refugia (P0) produces the highest attack intensity of caterpillars, which is 61% in the very high category and is markedly different from the use of refugia, especially the combination (P4) and Zinnia (P2) with an attack intensity of 28% in the medium category.
