Abstract

Tanaman cabai merupakan tanaman hortikultura yang mempunyai nilai ekonomi yang cukup tinggi, karena selalu dibutuhkan dan harganya cukup tinggi. Oleh karena itu banyak petani yang berusahatani cabai, namun harga cabai  tidak stabil. Fluktuasi harga yang cukup tinggi ini menyebabkan petani enggan menanam cabai.  Salah satu penyebabkan fluktuasi harga adalah masalah gangguang hama dan penyakit pada cabai.  Pada saat terjadi gangguan hama atau penyakit, produksi cabai turun secara drastis.  Oleh sebab itu petani perlu mengenal hama dan penyakit yang menyerang cabai serta gejalanya dan  bagaimana cara pengendaliannya. Pengenalan hama penyakit tanaman cabai dan penghitungan ambang ekonomi serta cara pengendaliannya telah dilakukan di Kelompok Tani Batu Tonggok yang terletak di jorong Gando, Nagari Paninggahan.  Kelompok tani ini sudah cukup lama membudidayakan tanaman cabai, namun terkendala dengan teknik budidaya terutama pengendalian hama dan penyakit cabai.  Hal ini berakibat produksi cabai tidak optimal.  Adanya kegiatan ini memberikan pemahaman kepada petani tentang hama dan penyakit cabai serta gejala dan penanganannya. Hama yang menyerang di antaranya adalah ; Thrips (Thrips parvispinus), Lalat Buah (Bactrocera sp.), Kutu Daun (Aphididae), Tungau (Polyphagotarsonemus latus dan  Tetranychus sp.),  Kutu Daun Persik ( Myzus persicae), Kutu Kebul ( Bemisia tabaci ), sedangkan penyakit di antaranya Layu Fusarium, Penyakit Virus kuning keriting, Penyakit Layu Bakteri Ralstonia,   Penyakit Busuk Buah Antraknosa dan Penyakit bercak daun.

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh jenis hidropriming dan lama penyimpanan benih terhadap viabilitas dan kekuatan benih kopi lokal Solok Selatan. Rancangan penelitian ini adalah rancangan acak kelompok (RAK) faktorial dengan dua perlakuan yaitu jenis hidropriming dan lama penyimpanan. Faktor pertama terdiri dari empat tingkat. Yaitu, P1 = Hydropriming dengan air biasa, P2 = Hydropriming dengan 100 ppm GA3, P3 = hydropriming dengan air kelapa, dan P4 = hydropriming dengan ekstrak bawang merah. Elemen kedua terdiri dari tiga tingkat. L1 = periode penyimpanan 1 minggu. L2 = periode penyimpanan 2 minggu. L3 = penyimpanan 3 minggu. Hasil evaluasi penelitian menjelaskan bahwa jenis hidropriming dan lama penyimpanan memiliki pengaruh interaksi namun tidak berpengaruh nyata terhadap potensi tumbuh maksimum, indeks vigor, dan laju perkecambahan. Jenis hidropriming yang memberikan hasil  baik dalam hal potensi pertumbuhan maksimum, indeks vigor dan laju perkecambahan adalah penggunaan air biasa dan ekstrak bawang. Kedua jenis hydropriming ini dapat membantu meningkatkan kadar air dan daya serap benih sehingga meningkatkan kelangsungan hidup dan vigor benih. Selain itu, umur simpan benih kopi dalam jangka panjang adalah satu minggu penyimpanan. Hal ini menunjukkan respon yang baik terhadap viabilitas.

Abstract

ABSTRACTWater stress disrupts plant growth, especially chili plants, which results in decreased yields, crop failure or plant death. One strategy to increase chili plant tolerance can be done through fertilization, organic fertilizer, mycorrhiza and other microorganisms. The study aims to determine the effect of several levels of water supply and organic fertilizer on the growth of curly chili varieties AKA in the early vegetative and generative phases. The study used a complete randomized block design with 12 treatments with 3 replications. The treatments are: P0. Field capacity water supply, P1. Field capacity water irrigation (FC) + 60ml cow urine, P2. Water irrigation FC + 10ml/L amiboost, P3. FC water irrigation + 15g mycorrhiza, P4. 50% FC water irrigation, P5. 50% field capacity water irrigation + 60ml cow urine, P6. 50% FC + amiboost 10ml/L, P7. 50% FC water irrigation + mycorrhiza 15g, P8. 25% FC water irrigation, P9. 25% FC water irrigation + cow urine 60ml, P10. 25% FC water irrigation + amiboost 10ml/L, P11.  25% FC water irrigation + mycorrhiza 15g. The results showed that watering with water below 50% FC reduced plant growth in the early vegetative and generative phases. This can be seen in all observed variables, decreasing significantly. The growth of plants given 100% FC water was very good, especially in the treatment of adding amiboost and cow urine. The addition of liquid organic fertilizer and mycorrhiza to plants given water below 50% KL has not been able to increase the growth of chili plants at the age of 2 months after planting.

Abstract

Tanjung Alai is among the nagari working towards becoming a central area for dragon fruit production. However, in the development of its cultivation, Tanjung Alai nagari community has found various obstacles in its cultivation technology, especially in maintenance technology and pest and pest control. Of course, this will indirectly reduce the quality and quantity of dragon fruit production. In response to these problems, we provide solutions that can overcome Nagari Tanjung Arai's partner problem by conducting educational activities on the introduction and control technology of pests and diseases of dragon fruit. The implemented activity model includes activities to provide information on various technologies for controlling plant pest organisms that hinder the development of dragon fruit growth and production, and continues a sharing session to determine the level of understanding of the agricultural community of the information presented. Based on the review of the implementation of this activity, it can be seen that the education carried out can improve the ability and insight of Dragon fruit farmers in overcoming and tackling plant-destroying organisms that hinder the development of Dragon fruit.

Abstract

The development of superior cultivars and the availability of high-quality seedlings require stable in vitro propagation. This study evaluated the effectiveness of different culture media for the in vitro propagation of local West Sumatra cayenne peppers using a Completely Randomized Design with eight treatments and six replications. Further testing used the Duncan Multiple Range Test. This research was conducted in the tissue culture laboratory of Mahaputra Muhammad Yamin University, Solok, West Sumatra. Callus initiation and shoot regeneration were conducted on MS medium with various auxin–cytokinin combinations, while root induction was tested on MS and WPM supplemented with auxins. Explants consisted of the first leaf and epicotyl from 21-day-old chili seedlings. The highest callus induction (100%) was observed on MS medium supplemented with 3 mg/l BAP + 0.5 mg/l IAA and MS medium supplemented with 4 mg/l 2,4-D for both types of explants. The highest embryogenic callus formation (98.45%) was obtained on MS + 3 mg/l BAP + 0.5 mg/l IAA. Optimal shoot regeneration (5.29 shoots) was achieved on MS + 2 mg/l BAP + 1 mg/l NAA, whereas the best root induction occurred on WPM + 1 mg/l NAA.

Abstract

Tomato (Lycopersicum esculentum L.) is a horticultural crop of considerable economic importance, valued for its nutritional and functional properties. Despite its potential, enhancing tomato productivity remains a critical challenge. This study aims to evaluate the effectiveness of integrated fertilizer application and to determine the optimal dosage of the combination of goat manure bokashi and banana peel–based liquid organic fertilizer (POC) on the vegetative growth and fruit yield of tomato plants. The experiment was conducted from April to July 2024 in Supayang Village, Payung Sekaki District, Solok Regency, West Sumatra Province, situated at an elevation of 700 meters above sea level. A Randomized Block Design (RBD) was employed, comprising six treatment groups and four replications. The treatments included: PO (control), P1 (bokashi 20 tons/ha + POC 120 ml/L), P2 (bokashi 20 tons/ha + POC 170 ml/L), P3 (bokashi 20 tons/ha + POC 220 ml/L), P4 (bokashi 20 tons/ha), and PS (POC 220 ml/L). Statistical analysis revealed that the integrated application of goat manure bokashi and banana peel POC significantly influenced plant height, stem diameter, days to 50% flowering, harvest time, and fruit count per plant. However, no statistically significant effect was observed on fruit weight per plant across the treatments.
