Abstract

This study is about the analysis of oil palm seedlings (Elaeis guineensis Jacq) stressed by drought against the administration of arbuscular mycorrhizal fungi (AMF) in pre nursery. This study aims to determine the effect of AMF on morphophysiology and biochemistry of oil palm seedling growth in pre nursery. This research was conducted at the UPT experimental garden (upper land), Faculty of Agriculture, Andalas University, Padang with an altitude of ±200 meters above sea level (masl). Observation of root colonization and proline accumulation tests were conducted at the Plant Physiology Laboratory, Faculty of Agriculture, Andalas University, Padang. The study was conducted from June to September 2024. The design used was a Completely Randomized Design (CRD) consisting of 2 factors, the first factor was the level of drought stress 4 treatment levels, namely field capacity (100, 75, 50 and 25%), the second factor was the dose of AMF 2 treatment levels, namely (10 grams/seedling, 15 grams/seedling). The data were analyzed statistically using the F test at a significance level of 5%, if the calculated F was greater than the F table, then continued with Duncan's New Multiple Range Test (DNMRT) at a significance level of 5%. The results of this study indicate that there is an interaction between field capacity treatment and AMF dose on the growth of oil palm seedlings, in observing proline accumulation test. The AMF dose of 10 grams showed the best results for all observation variables. The field capacity of 75% showed the best results for all observation variables.

Abstract

Seedless watermelons, both seeds and fruits, possess a significantly higher economic value than their seeded counterparts. Serif Saga Agrihorti, a variety developed by the Tropical Fruit Research Institute, offers several advantages, including a sweet taste, high fruit yield, bright red flesh, and large fruit size. However, it is characterized by a relatively high number of seeds. The development of a new seedless variety from Serif Saga Agrihorti is crucial. Polyploid induction using mutagenic agents like colchicine is an effective method to obtain tetraploid female parents. This study aimed to identify the optimal method and colchicine concentration for inducing polyploidy in watermelons and to produce putative tetraploid plants. Polyploid induction was conducted using two methods: directly applying colchicine solution to plant shoots and soaking seeds in colchicine solution for 24 and 48 hours at concentrations of 0.2% and 0.4%. The observed traits included stem diameter, leaf length and width, stomatal length and width, pollen diameter, pollen viability, male and female flowering periods, harvesting time, fruit weight, fruit diameter, seed count, and seed dimensions (length and width). Data were analyzed using an unpaired t-test using the Statistical Tools for Agricultural Research (STAR) software. The results identified four putative tetraploid genotypes based on morphological observations of pollen diameter, stomatal size, and seed dimensions. In conclusion, seed soaking in colchicine solution effectively induces polyploidy in watermelons compared to shoot application.

Abstract

This study aims to evaluate the effect of various doses of coal fly ash ameliorant on the growth and yield of several local rice varieties of West Sumatra on peatlands. Peatlands that have low fertility, high acidity, and limited nutrient content are the main challenges in rice cultivation. Fly ash, which is waste from coal combustion, is used as an ameliorant because it contains silica and other minerals that can improve soil structure, increase pH, and provide nutrients. The four rice genotypes used were Bujang Merantau, Kuriak Supayang, Redek, and PB 42, with four doses of fly ash (0, 5, 10, and 15 tons/ha). The study was conducted using a split-plot design, with the results showing that fly ash increased soil pH from 3.83 to 6.65, improved water content, and increased C-organic content. The optimal dose of fly ash was 10 tons/ha, which supported plant height. 2. Genotypes Redek and Bujang Merantau showed the best results in the number of filled grains per panicle and yield weight per hectare at this dose. The provision of higher doses still needs to be evaluated further. This study concluded that the combination of varieties and the right dose of ameliorant has the potential to increase local rice productivity on peatlands sustainably.

Abstract

This research aims to analyze the suitability of land for avocado cultivation (Persea americana Mill.) in Nagari Taeh Bukik, Payakumbuh District, Limapuluh Kota Regency, West Sumatra. The evaluation was carried out using an integrative approach which included spatial, laboratory and biophysical analysis to determine the level of land suitability based on environmental parameters that influence the growth of avocado plants. The research area is at an altitude of 499.2–1,241.7 meters above sea level with annual rainfall of 2,000–2,500 mm and is dominated by podzolic, latosol and glei humus soil types. The research method included taking 13 soil samples for analysis of physical and chemical properties (texture, pH, organic C content, nitrogen, phosphorus, potassium, and cation exchange capacity). Spatial analysis was carried out using a Geographic Information System (GIS) based on Landsat and DEMNAS imagery with thematic map overlays including soil type, land cover, and slope slope. The results of the research show that 30.97% of the area is classified in the S2tc class (sufficiently suitable for temperature limitations), 18.77% is included in the S2wa class (sufficiently appropriate for limited rainfall), 30.55% is in the S3tc class (marginally in accordance with temperature limitations), and 19.70% of the area is classified as unsuitable (N) for avocado cultivation. The main limiting factors found were temperature >30°C, high rainfall, and soil acidity level (pH 5.0–6.0). As recommendations, several land management strategies are proposed, namely: (1) implementing a drainage and irrigation system in the S2wa area to overcome rainfall constraints, (2) using heat-resistant varieties and implementing a partial shade system in the S2tc and S3tc areas to reduce the impact of high temperatures, and (3) diverting unsuitable land (N) for conservation or cultivation of other adaptive plants. This study confirms that 80.3% of the Nagari Taeh Bukik area has considerable potential for the development of avocado plants with the implementation of appropriate management strategies. It is hoped that the results of this research can be a reference in planning sustainable land use, supporting spatial data-based agriculture, and increasing avocado production in the region.

Abstract

Pruning, combined with fertilization, is a feasible agricultural technique to extend the harvest period of bird's eye chilli plants, thereby enhancing farmers' income. This study aimed to examine the interaction between controlled-release fertilizer (CRF) and NPK doses and to determine the optimal dosage of both fertilizers, considering the residual effects of CRF on the growth and yield of bird's eye chilli plants following pruning on Ultisol soil. The experiment was conducted from September 2024 to January 2025 at the Experimental Farm of the Faculty of Agriculture, Universitas Andalas. A Split-Plot Randomized Complete Block Design was employed, with the main plot representing the residual effects of CRF, while the subplots corresponded to different CRF and NPK dosages. The main plot treatments included CRF residual effects at 750 kg/ha, 1000 kg/ha, and 1500 kg/ha, whereas the subplots consisted of CRF application at 750 kg/ha, 1500 kg/ha, and NPK at 1200 kg/ha. Data were subjected to variance analysis (ANOVA) and further assessed using Duncan's Multiple Range Test (DMRT) at a 5% significance level. The results indicated no statistically significant interaction between CRF and NPK dosages and the residual effects of CRF. Applying CRF at 750 kg/ha was the most effective across all residual CRF levels among all tested treatments. The residual CRF dose of 1500 kg/ha positively impacted plant development and fruit production. The findings also revealed that the residual CRF effect contributed to an increased nitrogen supply in the soil, reducing the necessity for additional nitrogen fertilization for bird's eye chilli after pruning cultivation.

Abstract

Tomatoes are multipurpose vegetables, in addition to being used as vegetables, they can also be used as raw materials for food processing. Red Yellow Podsolic (RYP)) soil which is widely found in the Rokan Hilir area, has a relatively low fertility level and tends to be acidic. Therefore, choosing the right type and dose of organic fertilizer is very important to improve soil quality and support the growth of tomato plants. The purpose of this study was to obtain the best dose of manure for the growth and yield of tomato plants on Red Yellow Podsolic (RYP) soil. This study used a completely randomized design (CRD) with 2 factors. The first factor is the type of organic fertilizer (P), namely cow manure and goat manure. The second factor is the dose of organic fertilizer (D) consisting of 500 g/plant, 1000 g/plant, 1500 g/plant and 2000 g/plant. The observation data were explained statistically by the analysis of variance (F test). The results showed that the provision of cow manure had a significant effect on flowering age, harvest age and root volume. The administration of a fertilizer dose of 2000 g/plant gave a significant effect on the observation of plant height, root length, and root volume. The administration of goat manure had a significant effect on the observation of the number of fruits per plant and the weight of fruits per plant.
