Abstract

AbstrakSalah satu strategi yang diterapkan pada pupuk hayati untuk menunjukkan efek positif pada tanaman yang diinokulasi adalah pemilihan teknik aplikasi dan dosis yang tepat, baik pada tanah, benih, atau kombinasi keduanya. Tujuan dari percobaan ini adalah mendapatkan teknik aplikasi dan dosis pupuk hayati pelarut K yang memberikan hasil terbaik terhadap penyerapan K dan pertumbuhan tanaman jagung (Zea mays L.) pada Inceptisols Jatinangor. Percobaan dilaksanakan pada November 2018-Januari 2019 di rumah kaca Fakultas Pertanian Universitas Padjadjaran. Percobaan menggunakan rancangan acak kelompok dengan 9 perlakuan dan 3 kali ulangan. Perlakuan terdiri dari tanpa perlakuan (kontrol), aplikasi pada benih 400 g.ha-1 dan 800 g.ha-1, aplikasi pada tanah 2 kg.ha-1 dan 4 kg.ha-1, dan kombinasi antara kedua teknik aplikasi dan dosis tersebut. Hasil percobaan menunjukkan aplikasi pupuk hayati pelarut K dengan dosis 4 kg.ha-1 dapat meningkatkan populasi BPK total 52,86% dibandingkan kontrol dan berkorelasi positif terhadap konsentrasi K2O (r=0,64**), serapan K (r=0,59**), dan diameter batang tanaman jagung (r=0,46*) yang dibudidayakan di tanah Inceptisols Jatinangor.Kata Kunci: Aplikasi pada tanah ∙ Aplikasi pada benih ∙ Bakteri pelarut kalium ∙ Dosis ∙ Jagung AbstractOne of the strategies applied to biofertilizers to show a positive effect on the inoculated plants is the selection of the appropriate application technique and dose in soil, seeds, or a combination of both. The purpose of this experiment was to obtain the application technique and dose of potassium (K) solubilizing biofertilizer that gave the best results on K uptake and growth of maize (Zea mays L.) on Inceptisols of Jatinangor. The experiment was performed in November 2018-January 2019 in the greenhouse of the Faculty of Agriculture, Universitas Padjadjaran. The experiment used a single factor randomized block design with 9 treatments and 3 replications. The treatments consisted of control, seed treatment at doses of 400 g.ha-1 and 800 g.ha-1, soil treatment at doses of 2 kg.ha-1 and 4 kg.ha-1, and a combination of the two techniques application and doses. The results showed that the application of K solubilizing biofertilizer at a dose of 4 kg.ha-1 could increase the total PSB population by 52.86% compared to control and it was positively correlated with concentration of K2O (r=0.64**), K uptake (r=0.59**), and maize stem diameter (r=0.46*) grown on Inceptisols of Jatinangor.Keywords: Soil treatment ∙ Seed treatment ∙ Potassium solubilizing bacteria ∙ Dose ∙ Maize

Abstract

AbstractPresent study aimed to perform literature review to investigate the current status and potential use of plant growth promoting rhizobacteria (PGPR) for enhancing the soil plant’s health, plant growth and productivity in sustainable ways. The Systematic Literature Review (SLR) methods was applied according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) on published scientific literature from 2012-2022. Results revealed that genus diversity of PGPR (Bacillus sp., Serratia sp., Streptomyces sp., Pseudomonas sp., and Burkholderia sp.) produce siderophore and phytohormones such as indole-3-acetic acid (IAA), gibberellin (GAs), auxin, and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity, organic acids, biocontrol agent that contribute to the improvement of nutrient bioavailability (nitrogen fixing, phosphate solubilizing and Fe-uptake). The growth character of rice inoculated with biofertilizer and combined with 50% inorganic fertilizer produced no significant difference with pots that received 100% inorganic fertilizer. These results concluded that PGPR that produced phytohormone and siderophore could be developed as a potential bioagent or biofertilizer to improve the growth character and yield of upland rice (Oryza sativa L.) in dry environmental conditions.Keywords: PGPR producing phytohormone and siderophore, N2-fixer, Biofertilizer, Systematic review AbstrakKajian tinjauan pustaka ini dilakukan untuk menyelidiki status saat ini dan potensi penggunaan rizobakteri pemacu pertumbuhan tanaman (PGPR) untuk meningkatkan kesehatan tanah, pertumbuhan tanaman, dan produktivitas secara berkelanjutan. Metode Systematic Literature Review (SLR) diterapkan sesuai dengan Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) pada literatur ilmiah yang diterbitkan dari 2012-2022. Mesin pencari Google Scholar dan ScienceDirect dengan kata kunci yang tepat digunakan untuk memilih dan mengumpulkan jurnal ilmiah yang terindeks bereputasi dan digunakan sebagai referensi utama database. Hasil penelitian menunjukkan bahwa keragaman genus PGPR (Bacillus sp., Serratia sp., Streptomyces sp., Pseudomonas sp., dan Burkholderia sp.) menghasilkan siderophore dan memproduksi phytohormon seperti indole-3-acetic acid (IAA), giberelin (GAs), auksin, dan 1-aminocyclopropane-1-carboxylic acid (ACC) aktivitas deaminase, asam organik, agen biokontrol yang berkontribusi pada peningkatan bioavailabilitas nutrisi (pengikatan nitrogen, pelarutan fosfat, dan penyerapan Fe). Karakter tumbuh padi yang diinokulasi pupuk hayati dan dikombinasikan dengan pupuk kimia dosis 50% menghasilkan perbedaan yang tidak nyata dengan pot yang menerima pupuk anorganik 100%. Hasil ini menyimpulkan bahwa PGPR penghasil pitohormon dan siderophore dapat dikembangkan sebagai bioagent atau pupuk hayati yang potensial untuk meningkatkan karakter tumbuh dan hasil padi (Oryza sativa L.) gogo pada kondisi lingkungan yang kering.Keywords: PGPR produksi fitohormon dan siderofor, penambat-N2-fixer, biofertilizer, Systematic review

Abstract

Soil fertility is recognized as a crucial factor in supporting plant growth and productivity. The utilization of biofertilizers as environmentally friendly fertilizers is aimed at enhancing soil fertility and plant productivity. This study aims to explore the potential of local material for developing local wisdom biofertilizers (LWB) for achieving sustainable agriculture. A systematic literature review was conducted using bibliometric analysis, Preferred Reporting Items for Systematic Reviews, and Meta-Analyses (PRISMA) method, employing the Scopus search engine with the keywords "local AND wisdom AND biofertilizer" OR "biofertilizer" OR "local AND microorganism" OR "soil AND health OR crop AND productivity OR sustainable agriculture". The search yielded 704 articles, of which 11 were deemed eligible after selection. Based on the literature review, it was found that there are local materials, including fish waste, seaweed, Azolla, fruit waste, Moringa oleifera, microalga, bamboo roots, banana hump, golden snail, mangrove leaves, fruit, and vegetable waste that can be used as raw materials for LWB to improve soil health, plant growth, and productivity. The development of LWB as a new fertilizer technology faces challenges such as lack of regulations, low public trust, limited farmer awareness, weak promotion, and raw material shortages. Further research is needed to intensively study and enhance the effectiveness of LWB through enrichment using beneficial microorganisms.
