Abstract

This research was conducted to systematically examine scientific evidence regarding the mechanisms and synergistic impacts of PGPR and intercropping on Water Use Efficiency (WUE) and Nutrient Use Efficiency (NUE) in drylands. The method used was a systematic literature study with a search for peer-reviewed articles and strict selection of research evaluating WUE and NUE parameters in intercropped crops and crops inoculated with PGPR. The results showed that intercropping systems can increase soil water retention, improve microclimate conditions, and optimize the utilization of space and nutrients between plant species. PGPR contributes to improving plant growth through nitrogen fixation mechanisms, phosphate dissolution, phytohormone production, and strengthening tolerance to drought stress. The synergy between these two approaches enhances the plant's ability to utilize water and nutrients more efficiently, thereby implying an increase in productivity and sustainability of dryland agricultural systems. These findings emphasize the need for verification through field trials, development of adaptive local PGPR isolates, and institutional and policy support to expand the application of this technology to drylands.

Abstract

Lahan suboptimal memiliki potensi besar sebagai lahan pertanian produktif di masa depan. Untuk meningkatkan efisiensi penggunaan lahan, sistem tumpangsari merupakan alternatif budidaya yang efektif. Penelitian ini bertujuan mengevaluasi pengaruh berbagai formulasi bioamelioran terhadap serapan nitrogen (N), fosfor (P), dan hasil tumpangsari jagung–kedelai. Penelitian dilaksanakan pada Juni–Agustus 2025 di Dusun Sumur Mual, Desa Pemenang Barat, Kecamatan Pemenang, Kabupaten Lombok Utara. Analisis biologi dan kimia tanah dilakukan di Laboratorium Mikrobiologi dan Kimia Tanah, Fakultas Pertanian, Universitas Mataram. Rancangan Acak Kelompok (RAK) digunakan dengan lima perlakuan dan tiga ulangan, yaitu: P0 (tanpa bioamelioran), F1 (10% kompos, 10% pupuk kandang, 10% biochar sekam, 70% pupuk hayati mikoriza), F2 (15%, 15%, 15%, 55%), F3 (20%, 20%, 20%, 40%), dan F4 (25%, 25%, 25%, 25%). Hasil penelitian menunjukkan bahwa perlakuan F4, yang terdiri atas campuran 25% kompos, 25% arang sekam, 25% pupuk kandang, dan 25% pupuk hayati mikoriza, menunjukkan hasil terbaik dalam meningkatkan populasi spora mikoriza dan persentase kolonisasi akar. Perlakuan ini juga memberikan hasil panen jagung dan kedelai yang lebih tinggi, serta meningkatkan konsentrasi hara tanah (N total dan P tersedia) dan serapan hara oleh tanaman. Aplikasi bioamelioran F4 mampu meningkatkan efektivitas bioamelioran dalam mendukung pertumbuhan dan produktivitas tumpangsari jagung- kedelai.

Abstract

Secondary metabolites are crucial for plant resistance to biotic and abiotic stress. Fertilization with phosphorus (P), magnesium (Mg), and copper (Cu) can enhance secondary metabolite production, supporting plant defense mechanisms. This study evaluated the effects of P, Mg, and Cu fertilization on nutrient absorption and the production of phenolic and flavonoid metabolites in Pendok rice during vegetative and generative phases. A randomized block design with seven nutrient treatments and three replications was applied, involving 21 pots in a greenhouse. P was supplied as Super Phosphate Ca(H2PO4) (SP-36) and Phosphate Rock (PR). Mg and Cu treatments included combinations with and without their addition. Results showed that SP-36 with Mg produced the highest phenolic content during the vegetative phase, significantly higher than other treatments with 7.80 mg (GAE).g extract-1. Mg increased phenolic levels, while Mg and P had a significant effect (95% confidence level) on flavonoid and phenolic content during both growth phases. In conclusion, Mg and P fertilization effectively enhanced secondary metabolite production, improving plant resilience through nutrient optimization. These findings emphasize the role of proper nutrient management in boosting secondary metabolite quality in rice cultivation.

Abstract

ACC deaminase-producing rhizobacteria play an important role in enhancing plant growth and health, particularly under environmental stress condition. This study focused on isolating and determining the population of potential ACC deaminase-producing rhizobacteria from the rhizosphere of peanut plants (Arachis hypogea L.) grown under varying moisture level. Bacterial population was measured using the Standard Plate Count (SPC) method on Dworkin-Foster (DF) medium supplemented with 3 mM.L-1 ACC as the sole nitrogen source. The isolated bacteria were screened based on their ability to grow after 24 hours of incubation on the selective medium. Result showed that bacterial colonies on nutrient agar (NA) medium varied in color, while colonies on the selective medium were uniformly white. The total population of ACC deaminase-producing rhizobacteria generally declined as soil moisture decreased, nevertheless, the sample at 80% available water contained fewer bacteria (7.3 x 103 cfu.g-1 soil) than those (9.7 x 105 cfu.g-1) at 50%. In an additional experiment, 9 out of 11 selected isolates were found to potentially produce ACC deaminase, with 5 of these being diazotrophic bacteria. This study contributes valuable information for designing irrigation systems in sustainable land management, particularly concerning plant-beneficial microbes that produce ACC deaminase and help plants tolerate environmental stressors.
