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.

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.

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.

Potato (Solanum tuberosum L.) is an important crop for food diversification, yet the productivity of the local Cingkariang variety from West Sumatra remains limited due to poor seed quality and viral infection. Tissue culture provides a reliable approach to produce pathogen-free planting material. This study evaluated the interaction of NAA and BAP concentrations on the in vitro growth of Cingkariang potato plantlets. Results revealed significant interactions between the two growth regulators on most growth parameters. The application of 0.3 ppm NAA enhanced node number, shoot formation, and plantlet height without suppressing root growth, while 2 ppm BAP was most effective for stimulating shoot development. These findings highlight the importance of optimizing plant growth regulator combinations to improve micropropagation efficiency of Cingkariang potato.

Gambir (Uncaria gambir Roxb.) is an important Indonesian export commodity used in the pharmaceutical, food, and leather tanning industries. The Cubadak variety is one of the superior varieties with high flavonoid and tannin content and resistance to pests and diseases. One of the obstacles in gambir propagation is uneven seedling growth, which affects plant productivity and quality. One approach to address this issue is by regulating light intensity through shading during the gambir seedling phase. This study aims to investigate the effect of shading intensity on the growth of Cubadak gambir seedlings. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Andalas University, using a Completely Randomized Design (CRD) with four levels of shading intensity (40%, 50%, 60%, and 70%) and three replications. Data were analyzed using an F-test at the 5% level, followed by Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results of the study indicated that 60% shading provided the best effect on gambir seedling growth, as evidenced by increased plant height, number of leaves, leaf area, and other morphological and physiological parameters. A shading intensity of 60% is recommended as the optimal condition for the growth of Cubadak gambir seedlings.
