Abstract

Red chilies are one of the horticultural commodities that have high economic value in Indonesia. Red chili production in Indonesia in 2021 will reach 136 million tons, with Riau province experiencing a decline in production which causes a production deficit in the province. To increase production, it is necessary to improve red chili cultivation techniques. The growth of red chili plants is influenced by internal and external factors, including ideal rainfall ranging from 600 mm/year to 1,250 mm/year. Rainfall that is too high can cause air humidity to increase and plants are more susceptible to disease. Red chili plants also require slightly hot daytime temperatures and sufficient water availability. In the rainy season, the risk of red chili crop failure is high because the plants cannot tolerate standing water. Excess water can cause plant root rot and diseases such as bacterial wilt and anthracnose. Therefore, it is necessary to develop red chili cultivation techniques in the rainy season, such as making the right planting schedule, understanding cultivation techniques, and using technical cultural measures such as making higher beds and using appropriate pesticides. With the right cultivation techniques, it is hoped that it can increase farmers' income and welfare. Red chili cultivation can also provide large profits if revenue is high and production costs are low. Therefore, it is important to optimize efforts to increase red chili production by using appropriate cultivation techniques during the rainy season. The aim of this community service activity is to increase public knowledge about cultivating chili plants during the rainy season in Teluk Piyai Pesisir.

Abstract

Celery offers a distinctive flavor to culinary dishes and has biopharmaceutical potential in addressing various health issues. Efforts to obtain high-quality celery in terms of appearance and content continue to be made to meet human needs. The objective of the study is to determine the morphological and physiological responses of celery plants to shade treatment and mung bean sprout extract. The experimental design used a completely randomized design with 2 factors, namely the provision of shade (without shade, 65% shade, 75% shade, and 85% shade) and the provision of bean sprout extract (without bean sprout extract, 10% bean sprout extract, and 30% bean sprout extract). Each treatment was repeated 3 times. Data were analyzed by analysis of variance and Duncan's New Multiple Range Test (5%). Results indicated that 85% shading combined with 30% mung bean sprout extract yielded the highest stomatal density. The same extract concentration also produced the highest chlorophyll a and total content. In contrast, 65% shading resulted in the largest leaf area of celery plants.

Abstract

Anthracnose is one of the main diseases in chili plants that causes a decrease in the quality and quantity of the harvest. This study aims to identify anthracnose disease in red chili (Capsicum annuum) and cayenne pepper (Capsicum frutescens) in Agrowisata Village, West Rumbai District. Observations were made through observation of symptoms in the field, pathogen isolation, and identification of colony and conidia morphology. The results of the observations showed the presence of typical anthracnose symptoms in the form of circular necrotic spots, dark sunken lesions, and rot on the fruit. Pathogen isolation on PDA media showed variations in colony color in both isolate sources, namely gray and peach in red chili and white and gray in cayenne pepper. Microscopic observations showed cylindrical conidia with both ends fusiform, according to the characteristics of Colletotrichum acutatum. Thus, it can be concluded that anthracnose disease in both types of chili is caused by C. acutatum. These findings are expected to be the basis for developing a more effective and sustainable disease control strategy for chili cultivation in the region.

Abstract

Kacang hijau termasuk salah satu tanaman pangan penting yang pertumbuhannya dapat dipengaruhi oleh senyawa alelopati dari gulma seperti alang-alang (Imperata cylindrica). Tujuan penelitian untuk mengevaluasi respons perkecambahan dan pertumbuhan awal kacang hijau terhadap berbagai konsentrasi ekstrak daun alang-alang serta menganalisis pengaruhnya terhadap viabilitas dan vigor benih kacang hijau. Penelitian dilaksanakan di Laboratorium Ekofisiologi, Fakultas Pertanian, Universitas Riau, menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal dengan lima taraf konsentrasi, yaitu 0% (kontrol), 5%, 10%, 15%, dan 20% ekstrak daun alang-alang yang diulang sebanyak empat kali. Parameter yang diamati meliputi daya berkecambah, kecepatan berkecambah, panjang akar dan hipokotil, berat basah, berat kering, serta indeks vigor I dan II. Hasil analisis ragam menunjukkan bahwa aplikasi ekstrak daun alang-alang pada konsentrasi 5% hingga 20% tidak berpengaruh nyata (p > 0,05) terhadap seluruh parameter pengamatan. Daya berkecambah yang mencapai 100% pada semua variasi konsentrasi mengindikasikan bahwa ekstrak daun alang-alang tidak bersifat fitotoksik dan tidak menghambat pertumbuhan awal benih kacang hijau. Analisis korelasi Pearson menunjukkan hubungan positif dan sangat kuat antara panjang akar/hipokotil dengan indeks vigor I (r = 0,76), serta berat kering dengan indeks vigor II (r = 0,998). Kata kunci : Alelopati, Imperata cylindrica, kacang hijau, perkecambahan, vigor

Abstract

The pre-nursery stage represents an initial phase that strongly influences the subsequent quality of oil palm seedlings. Nevertheless, information regarding leaf morphology and biomass distribution of oil palm seedlings under organic fertilization and water management remains limited. This study aimed to evaluate leaf morphological traits and biomass allocation of oil palm seedlings in response to oil palm empty fruit bunch (EFB) compost application and different watering intervals during the pre-nursery stage. The experiment was arranged in a completely randomized design with two factors and three replications, consisting of EFB compost rates and watering intervals. Observed variables included leaf area, leaf number, dry weight of leaves, stems, and roots, as well as shoot–root ratio. Data were analyzed using analysis of variance at the 5% significance level and followed by Duncan’s New Multiple Range Test when significant effects occurred. The results indicated no interaction between EFB compost application and watering intervals for all observed parameters. Individually, both treatments did not significantly affect leaf morphology or biomass distribution. However, a numerical tendency of increased plant biomass was observed up to an EFB compost rate of 225 g per polybag, suggesting that seedling responses during the pre-nursery stage develop gradually rather than immediately
