Abstract

As a genetic resource, local rice can provide insight into the inheritance of favorable traits. Local rice varieties have naturally been tested for resistance to pests and diseases, high yields, good rice quality (including class 1 quality), and a taste that people like, but also have some disadvantages, such as long life and high plant height that easily collapses. For this reason, the characteristics of local rice varieties that have these advantages are improved using the gamma-ray induced mutation technique. Before planting in the field, it is necessary to test the vigor and viability of local rice genotypes (Oryza sativa L.) Padang Pariaman seeds first. In this study, researchers used three different rice varieties, namely: "Madang Pulau", "Putiah Papanai", and "Banang Kuniang" and gamma irradiation, with radiation doses of 0, 100, 200, 300, 400, 500, and 600 Gy. Based on the results of the study, the local rice seed varieties of Padang Pariaman Regency and the dose of gamma irradiation had a significant effect on maximum germination, while germination speed, germination capacity, vigor index, and growth uniformity were significantly affected by the dose of gamma irradiation. Gamma irradiation with doses of 400-600 Gy resulted in a more significant decrease in seed vigor and viability compared to irradiation with doses of 100-300 Gy.

Abstract

Maize is a second important food crop, its yield is the raw material for the feed industry. As for other crops, maize can not avoid weed association and interference. Weed may cause farmers’ economic loss. An experiment to determine the efficacy of thiencarbazone methyl+isoxaflutole herbicide and its effects to control weeds and maize yield was conducted from October 2022 to February 2023 at Ultisol of Universitas Andalas, Limau Manis, Padang. The experimental units were laid out according to a completely randomized block design (CRBD) with 10 treatments and three replications. The treatment was different types of weed control namely: no weeding, various doses of herbicide thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 i.e 250 mL ha-1, 300 mL ha-1, 350 mL ha-1, and 400 mL ha-1 applied at 2 and 10 DAP, respectively, and manual weeding. Herbicide thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 effectively controlled Erechtites valerianifolia, Oxalis barrelieri, and Asplenium rhizophyllum. Herbicide at 350 mL ha-1 applied dose at 2 DAP reduced weed dry weight per m-2 as much as 93% at 6 WAP. Weed control by herbicide application increased 72.20% of maize yield per ha compared to the no-weed-control treatment group without causing phytotoxicity on maize plants.ABSTRAK Tanaman jagung merupakan tanaman pangan penting kedua dan menjadi bahan baku industri pakan. Seperti tanaman lainnya, tanaman jagung juga tidak dapat terhindar dari interaksi dan asosiasi dengan gulma. Keberadaan gulma pada pertanaman jagung dapat menimbulkan kerugian ekonomis.

Abstract

Weeds are plants whose presence is unwanted by humans because of competition with cultivated plants for nutrients, sunlight, and growing space, producing allelochemicals that interfere with plant growth, reduce production and product quality, and increase farming costs. The continuous use of synthetic herbicides has adverse effects on the environment and health, so it is necessary to seek a weed control mechanism that is more efficient and environmentally friendly. One is utilizing secondary metabolites, namely sunflower plant allelochemicals, that can control weeds. This study aims to determine the response of weeds to the application of extracts of sunflower plant parts as bioherbicides. This research was conducted in three stages: raw material preparation, extraction, and application. The results obtained 17 weed species in the experimental field of Nagari Selayo Tanang Bukit Sileh from 7 families (Asteraceae, Poaceae, Lythraceae, Polygonaceae, Brassicaceae, Caryophyllaceae, and Mazaceae) and two weed classes (broadleaf weeds and grasses). The bioherbicide efficacy of sunflower extract (Helianthus annus L.) has not caused symptoms of toxicity in weeds.

Abstract

Rainfall variability, in terms of amount, distribution, and timing, can increase the risk of crop failure and reduce crop yields. This study aims to analyze CHIRPS (Climate Hazards Group InfraRed Precipitation with Stations) rainfall dynamics across several coastal areas of West Sumatra and to evaluate agroclimatic zones to assess the suitability of climate-adaptive cropping patterns. Monthly rainfall data for the period 1995-2024 were analyzed using the IDW interpolation method to produce rainfall distribution maps. This study also classified agroclimatic zones using Oldeman's classification to assess the suitability of cropping patterns. The analysis showed significant annual rainfall fluctuations, with high rainfall dominating the 1995-2014 period and a decline in the 2015-2024 period. Changes in monthly rainfall patterns, particularly the increase in rainfall from March to May during the 2015-2024 period, may affect planting times and irrigation management. The three regions studied (Padang Pariaman, Pariaman, and Padang) are in climate zone A1, with more than 9 consecutive wet months, allowing year-round rice cultivation. However, rainfall fluctuations require adjustments in planting timing and the selection of secondary crops that are more drought-resistant. The results of this study provide a stronger basis for agricultural planning that is more adaptive to climate change, with recommendations for adjustments to the planting calendar and irrigation management to ensure the sustainability of efficient and sustainable agricultural production.

Abstract

Gamma ray irradiation is a mutagenesis method used to obtain new genetic variations in plants, including rice. Local varieties were chosen because they have good adaptability to the local environment and can play an important role in increasing agricultural productivity. The local varieties of rice seeds from Padang Pariaman Regency used in the research were "Madang Pulau", "Putiah Papanai" and "Banang Kuniang". The irradiation doses used were 100 Gy, 200 Gy, 300 Gy, 400 Gy, 500 Gy and 600 Gy. Seeds without irradiation were also used as controls. The results showed that the germination response of local varieties of rice seeds to gamma ray irradiation varied depending on the dose given. In terms of germination percentage, the irradiation dose of 100 Gy showed a significant increase compared to the control in the white Papanai variety. However, irradiation doses of 200 Gy and 300 Gy caused a significant reduction in germination percentage compared with the control. Apart from that, observations were also made on other parameters such as seedling height and root length. The results showed that at irradiation doses of 100 Gy, 200 Gy and 300 Gy, there was a significant reduction in these parameters. Based on these findings, it can be concluded that the use of gamma rays as an irradiation method can influence the germination response of local varieties of rice seeds in Padang Pariaman Regency differently depending on the dose and the variety used.

Abstract

Abstract: Bukit Sileh is known as an area that produces competitive high-quality vegetables in the regional market and potential to be an attractive natural tourist destination. However, there are several obstacles faced by the community, such as climate change (causing crop failure), limited quality inputs, pest and disease attacks, high operational costs and low selling prices. Therefore, efforts are needed to diversify and increase community income through grape cultivation. Grape production continues to increase but has not been able to meet domestic demand, thus providing promising business opportunities. This activity aims to improve the technical and managerial capacity of farmers and support the application of appropriate and sustainable technology. The implementation was carried out participatively in three main stages: surveying and mapping potential; training and technical assistance; and monitoring and evaluation. The results showed an increase in farmers' knowledge and skills in grape cultivation by applying greenhouse technology and drip irrigation systems with adaptive varieties. In addition, there was also an increase in understanding of marketing aspects through fruit quality testing. This activity successfully built a more professional and sustainable foundation for production and marketing to realize an independent village through the development of community-based agrotourism. Keywords: grapes, empowerment, technology, agrotourism, community service Abstrak: Bukit Sileh dikenal sebagai daerah penghasil sayuran berkualitas tinggi yang kompetitif di pasar regional dan memiliki potensi sebagai lokasi wisata alam yang menarik. Namun terdapat beberapa kendala yang dihadapi masyarakat, seperti perubahan iklim (menyebabkan gagal panen), terbatasnya input berkualitas, serangan hama dan penyakit, biaya operasional yang tinggi dan harga jual yang rendah. Maka dibutuhkan upaya diversifikasi peningkatan pendapatan masyarakat melalui budidaya tanaman anggur. Produksi anggur terus mengalami peningkatan namun belum mampu memenuhi permintaan dalam negeri, sehingga memberikan peluang usaha yang menjanjikan. Kegiatan ini bertujuan untuk meningkatkan kapasitas teknis dan manajerial petani serta  mendukung penerapan teknologi tepat guna dan berkelanjutan. Pelaksanaan dilakukan secara partisipatif dalam tiga tahapan utama: survei dan pemetaan potensi serta kebutuhan; pelatihan dan pendampingan teknis, serta monitoring dan evaluasi. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan petani dalam budidaya tanaman anggur dengan menerapkan teknologi greenhouse dan sistem irigasi tetes serta varietas unggul yang adaptif. Selain itu juga terjadi peningkatan pemahaman dalam aspek pemasaran melalui pengujian mutu buah. Kegiatan ini berhasil membangun fondasi produksi dan pemasaran yang lebih profesional dan berkelanjutan untuk mewujudkan desa mandiri melalui pengembangan agrowisata berbasis komunitas. Kata Kunci: anggur, pemberdayaan, teknologi, agrowisata, pengabdian
