Abstract

Farmers commonly use inorganic fertilizers such as urea, rock phosphate, and NPK in crop cultivation. Continuous use of these inorganic fertilizers can degrade the quality of the growing medium and increase production costs. Inorganic fertilizers are also relatively expensive. One way to address this issue is by utilizing allelochemical compounds as Liquid Organic Fertilizers (LOF) for plant cultivation. Applying fertilizers in liquid form is more easily absorbed by plants because they are already dissolved and readily available. Babandotan liquid organic fertilizer contains essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K). These elements play a crucial role in stimulating vegetative growth, promoting root development, and strengthening the plant's overall health. The objective of this activity is to enhance the knowledge of the members of the Banda Langik Women Farmers Group about liquid organic fertilizer made from Babandotan weed, as well as to fulfill the Higher Education Tri Dharma for lecturers in the Agrotechnology Program at the Faculty of Agriculture, Andalas University. This community service activity was conducted at the Banda Langik Women Farmers Group, located at Jl. Ekora RT01/RW07 Sungai Bangek, Balai Gadang Village, Koto Tangah District, Padang City, in May-June 2022. The activities performed included preparation, socialization, closing, and reporting. Based on the results of the activity, several key points were identified, including that the community service program was conducted according to the needs of the Women Farmers Group, the group was satisfied and found the service beneficial for their development in the future, and the group members were committed to using LOF in their cultivation areas.

Abstract

Cocoa is one of Indonesia's flagship commodities that significantly contributes to the nation's economy. However, recently, the fame of cocoa has been declining due to various issues affecting its cultivation, from upstream to downstream. One of these issues is the use of low-quality cocoa seeds, adversely impacting long-term production. This condition affects the enthusiasm of the community in cocoa cultivation, leading to a decline in national cocoa production. Hence, there's a need for early anticipation by socializing cocoa planting to the younger generation, especially those around the University Andalas campus in Padang. The objective of this activity is to impart knowledge about cocoa plants and the cocoa planting process to the younger generation around the University Andalas to support sustainable cocoa farming. The event took place in Sungai Balang, Pauh Kota Padang. The method employed was structured socialization to the younger generation at the University Andalas Campus. The activity's outcomes were evaluated through questionnaires. The results indicated high enthusiasm among the participants, with 87% expressing high satisfaction with the conducted activities, and 93% hoping for the sustainability of these initiatives. These results demonstrate an increased understanding among the younger generation at the University Andalas about cocoa plants, cocoa planting, and the entrepreneurial spirit based on cocoa planting. It's hoped that this initiative continues, supported by mentoring and guidance.

Abstract

The germination process is the key to plant phenology, which significantly influences the success of early plant growth. Some seeds have a dormancy, so the germination process is hampered or does not occur. However, dormancy-breaking treatments in plants have been widely reported, such as breaking the dormancy of sugar palm seeds through physical scarification. This research aims to determine the best scarification position to break the dormancy of sugar palm seeds. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Andalas from July to October 2023. The design was completely randomized with scarification in two position variations, the operculum (A1) and dorsal (A2) points, repeated thrice. The results showed that the position of seed scarification affected the emergence time of cotyledon petioles and coleoptiles, germination capacity, and seed moisture content. Scarification at the operculum point requires a dormancy break of 16 DAP (Days After Planting) compared to 29 DAP for the dorsal. Seed viability was good in seeds sacrificed at the operculum point, with a germination percentage of 81.94%. Keywords: dorsal, operculum, cotyledon petiole

Abstract

Indonesia has the potential to develop alternative food sources, one of the cereal crops that has the potential and prospects to be developed is job's tears (Coix lacrima-jobi L.). Efforts that can be made to increase job's tears production are variety selection, proper cultivation techniques, and favorable environmental conditions. Fertilization is one of the most important factors that need to be considered in plant cultivation techniques. This research was conducted in Padang city, West Sumatera. The research was factorial in the form of a complete random design. The job’s tears cultivars used in this riset were Pulut and Batu. The purpose of this study was to determine the effect of NPK fertilizer on growth and yields of two job’s tears cultivars. NPK fertilizer dosage treatment in this study consisted of : 0 kg/hectare, 100 kg/hectare, 200 kg/hectare, and 300 kg/hectare. The results showed that there was no interaction between NPK fertilizer and two job’s tears cultivars. Pulut showed the highest mean values on growth variables (plant height, leaf length, and stem diameter), but Batu showed the highest mean values on yield variables (seed weight / plant). While the best dose of NPK fertilizer to increase growth and yield is 300 kg/hectare.

Abstract

Expansion of soybean cultivation by utilizing land beneath tree canopies and adjusting plant populations can be considered as an alternative to increase national soybean production. The objective of this research is to examine the influence of seed quantity per planting hole on the agronomics of soybean variety Dena 1 under different lighting conditions. This study was conducted from August to November 2023 at the Experimental Garden of the Faculty of Agriculture, Andalas University. The experimental design used was a Completely Randomized Design (CRD) with two factors and three replications. The first factor was lighting conditions, while the second factor was the quantity of seeds per planting hole. Soybean plants under unshaded conditions showed the best influence on plant height, stem diameter, as well as an increase in pod number and percentage of filled pods. The interaction between the treatment of seed quantity per planting hole and different lighting conditions influenced the seed weight per plot, where planting two seeds per planting hole under unshaded conditions yielded the best result at 280.56 g.
