Abstract

Cendawan endofit hidup di dalam jaringan tanaman, tanpa menimbulkan gejala penyakit, bersimbiosis mutualisme dengan tanaman inang. Tujuan penelitian ini adalah mendapatkan cendawan endofit isolat lokal yang potensial dalam meningkatkan perkecambahan benih dan pertumbuhan bibit cabai . Untuk pencapaian tujuan tersebut pendekatan yang diterapkan adalah pengumpulan cendawan endofit pada pertanaman cabai, pengujian patogenesitas cendawan cendofit, dan pengujian pada perkecambahaan benih cabai. Metode yang digunakan dalam penelitian ini terdiri atas mengumpulkan cendawan endofit dari lapangan, menguji perkecambahan benih cabai pada masing-masing isolat cendawan, dan identifikasi makroskopis dan mikroskopis. Berdasarkan penelitian yang telah dilakukan diperoleh 65 isolat cendawan, 43 isolat diantaranya potensi sebagai patogen, 22 isolat diantaranya non patogen dan dapat meningkatkan perkecambahan benih serta pertumbuhan bibit cabai. Cendawan endofit yang diperoleh termasuk genus Fusarium, Gliocladium, Geotrichum, Penicillium, Aspergillus, Alternaria, Curvularia, dan hifa steril. Selanjutnya 22 isolat cendawan endofit akan diuji kemampuannya menginduksi ketahanan cabai terhadap infeksi virus, dalam upaya pengendalian virus secara terpadu (PHT) untuk mengatasi permasalahan infeksi virus pada tanaman cabai.

Abstract

This groundbreaking study ventures into uncharted territory to explore the vast potential of Plant Growth Promoting Fungi (PGPF) as multifaceted allies in agricultural sustainability. Departing from traditional paradigms, the research sets out to identify and characterize non-pathogenic fungal isolates with the capacity to serve as potent PGPF agents. Employing a pioneering approach, fungal isolates are meticulously collected from the rhizosphere of plants, heralding a new era of ecological exploration at the microorganism level. Rigorous testing for pathogenicity on soybean seeds unveils a rich reservoir of fungi diversity, with 18 isolates demonstrating remarkable efficacy in enhancing germination rates and promoting vigorous seedling growth. These findings not only underscore the pivotal role of PGPF in bolstering plant health and resilience but also herald a paradigm shift in sustainable agriculture. With the potential to serve as biopesticides for plant protection and biofertilizers for enhancing growth, these PGPF isolates offer a promising avenue for reducing reliance on synthetic inputs and mitigating environmental impacts. Moreover, their integration into integrated disease management strategies holds the promise of synergistic efficacy, paving the way for holistic approaches to agricultural sustainability. This research not only expands the frontiers of knowledge surrounding PGPF but also lays the groundwork for transformative innovations in agroecological practices, ushering in a greener, more resilient future for global agriculture.

Abstract

Apomecyna saltator, a notorious pest of honey pumpkin plants, poses a significant threat to both vegetative and generative phases, leading to considerable production losses. Despite its agricultural impact, there are limited studies on effective management strategies for this pest. This research investigates the effect of combined phosphorus and potassium fertilization on controlling A. saltator infestations in honey pumpkin plants. The study was conducted at the Teaching and Research Farm of the Faculty of Agriculture, Jambi University. A randomized block design with five treatments and five replications was used, testing different combinations of SP-36 phosphorus and potassium chloride (KCl) fertilizers: no fertilization (p0), SP-36 0.67 g/plant + KCl 1.25 g/plant (p1), SP-36 1.00 g/plant + KCl 1.88 g/plant (p2), SP-36 1.34 g/plant + KCl 2.51 g/plant (p3), and SP-36 1.67 g/plant + KCl 3.13 g/plant (p4). The variables observed included stem diameter, larval population, percentage of plant damage, number of attacked plant segments, fruit weight, and overall production. Data were analyzed using ANOVA and Duncan's Multiple Range Test (DMRT). The results indicated that combining phosphorus and potassium fertilizers significantly increased stem diameter, fruit weight, and yield while reducing larval populations, plant damage, and affected segments. The study demonstrates that phosphorus and potassium strengthen honey pumpkin plants and negatively impact A. saltator infestations. This research highlights a novel approach to pest control, showing that targeted fertilization promotes plant health and suppresses the honey pumpkin stem borer (A. saltator). This dual benefit of nutrient application provides a sustainable and efficient pest management strategy, offering a fresh perspective on integrated crop protection.
