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.

Abstract

Oil palm has the prospect of rapid development in Indonesia, which causes an increase in plantation area to continue. However, the problem that is still encountered is the low productivity and quality of crop production. The solution that can be used is the use of planting material derived from superior varieties. High-yielding varieties are assembled through hybridization of two varieties that have the desired superior properties. Observation of the flower development cycle is needed as the basis for the hybridization process. Flower development is not only influenced by genetic factors, but also by environmental factors, especially climate. Observations on plant responses are part of a phenological study. This research was carried out in April-August 2021 at Pabatu Gardens, PTPN IV with the aim of observing the flowering phenology of the DxP 540 NG and DxP Socfindo MT Gano varieties. The climatic conditions of the research location during the observation were an average temperature of 29°C, 80% humidity, and an average rainfall of 145 mm/month. The average time required for the DxP 540 NG variety of male and female flowers, the growth phase of the sheath until the outer sheath broke, was 40 days and 38 days, the outer sheath broke until the inner sheath burst was 15 days and 18 days, the inner sheath broke to full bloom was 12 days. days and 16 days, and in full bloom until the flowers are completely pollinated, namely 4 days and 6 days. The average time required for the DxP 540 NG variety of male and female flowers in the growth phase of the sheath until the outer sheath breaks are 32 days and 30 days, the outer sheath breaks until the inner sheath bursts are 16 days and 15 days, the inner sheath bursts to full bloom, namely 11 days and 15 days, and in full bloom until the flowers are perfectly pollinated, namely 4 days and 6 days. The total time required for flowering for the male and female DxP 540 NG varieties was 71 days and 78 days, while for the DxP Socfindo MT Gano variety, male and female flowers were 63 days and 66 days, respectively.

Abstract

One of the factors hindering the development of upland rice cultivation among annual crops is the limited number of shade-tolerant upland rice varieties. It is very important to assemble shade-tolerant upland rice varieties with high yields. The purpose of the study was to determine the effect of shade on the growth and productivity of five genotypes of upland rice. This research was carried out in the experimental garden of the Faculty of Agriculture, the Islamic University of North Sumatra with an altitude of 25 m above sea level, from June to December 2020. The research design was split-plot and repeated three times. The main plot of shade treatment consisted of two levels, namely no shade (0%) and shade treatment (70%). The sub-plots were five genotypes of upland rice in Deli Serdang and two shade-tolerant varieties. Shade treatment affected the growth and productivity of five genotypes of upland rice in Deli Serdang District (Sialus, Arias, Ramos Merah, Silayur, and Sirabut) and two shade-tolerant varieties (Rindang 1 and 2). Two genotypes of upland rice were obtained, namely Silayur and Sirabut which were more shade tolerant, based on flowering age, harvest age, and grain weight per clump. When compared with Rindang 1 and 2 varieties, the two genotypes of upland rice were the same or more tolerant.

Abstract

The application of true shallot seed cultivation technology with the planting spacing and number of seedlings per planting hole is expected to increase the productivity of shallots in Indonesia. The research was carried out at KP Sukarami-AIAT West Sumatra from January to June 2021. The aim of the study was to obtain recommendations for the appropriate planting spacing and number of seedlings per planting hole in increasing the growth and yield of true shallot seed in West Sumatra. The study used a 2-factor factorial design in a randomized block with 3 replications. The first factor is the planting spacing (JT), which consists of 3 types, namely: JT1 (10 cm x 10 cm), JT2 (10 cm x 15 cm), and JT3 (15 cm x 15 cm). The second factor is the number of seedlings per planting hole (JB) which consists of 5 types, namely: JB1 (1 seedling), JB2 (2 seedlings), JB3 (3 seedlings), and JB4 (4 seedlings). The results showed that there was not significant interaction between the planting spacing and the number of seedlings per planting hole on the yields of true shallot seed. The highly significant interaction was only found in the growth components and yield components. The best planting spacing is 10 cm x 10 cm and 10 cm x 15 cm, while the best number of seedlings is 1-2 seedlings per planting hole. It is recommended to use a planting spacing of 10 cm x 10 cm or 10 cm x 15 cm with 1-2 seedlings per planting hole in true shallot seed in the highlands of West Sumatra.
