چکیده

Fosfat merupakan salah satu unsur yang berperan penting bagi pertumbuhan tanaman dan kesuburan tanah. Namun, ketersediaan P terlarut dapat diserap oleh sangat kecil karena berikatan dengan kation berada di dalam Salah upaya meningkatkan tersedia tanah adalah pemanfaatan agen hayati Bakteri Pelarut (BPF). Penelitian ini bertujuan untuk menguji isolat BPF kelarutan padi pada uji hayati. Percobaan dilaksanakan Rumah Kaca Departemen Ilmu Tanah Sumber Daya Lahan, Fakultas Pertanian, Universitas Padjadjaran. Rancangan percobaan digunakan Acak Kelompok (RAK) 6 perlakuan 5 ulangan. Masing-masing jenis bakteri kontrol, Bacillus substilis, B. megatherium, Pseudomonas mallei, Burkholderia sp., campuran. Hasil menunjukkan diuji memiliki kemampuan bervariasi enzim fosfatase, P, Lebih lanjut, campuran memberikan pengaruh lebih baik terhadap aktivitas dibandingkan tunggal.ABSTRACTPhosphorus is an element that important for soil fertility and plant growth. However, the phosphate nutrient can be uptaken by plants only in a small amount because it binds to cations soil. The effort enhancing availabilty phosphorus solubilizing bacteria (PSB). This study aimed test PSB isolates increasing solubility rice growth using bioassay. experiment conducted at greenhouse Jatinangor District, Sumedang Regency, West Java with Randomized Block Design (RBD) five replications. Each type of treatment was control, mixed isolates. results showed had various abilities enhance phosphatase, solubility, Furthermore, better effect on phosphatase activity, dissolved than single

Increase phosphorus availability from the use of alfalfa (Medicago sativa L) green manure in rice (Oryza sativa L.) agroecosystem

Alfalfa is a good green manure source, but its effect on rice growth has not been fully elucidated. Two green manure species, alfalfa and broad bean (Vicia faba L.), and two N fertilizer levels, alone or combination, were applied to a rice field. The results indicated that alfalfa had more pronounced effects on increasing soil labile phosphorus (P) fractions (including NaHCO3-Pi, NaOH-Pi), P up...

Effects of Molybdenum on Phosphorus Concentration in Rice (Oryza sativa L.)

A hydroponic trial was carried out to investigate the effect of molybdenum (Mo) on uptake of phosphorus (P) in different rice cultivars. The experiment was conducted using a randomized complete-block design, with a split-plot arrangement of treatments and three replications. Four rates of Mo (0, 0.01, 0.1 and 1 mg L) and five cultivars (MR219, HASHEMI, MR232, FAJRE and MR253) provided the main ...

Endophytic colonization of rice (Oryza sativa L.) by the diazotrophic bacterium Burkholderia kururiensis and its ability to enhance plant growth.

Burkholderia kururiensis is a diazotrophic bacterium originally isolated from a polluted aquifer environment and presents a high level of similarity with the rice endophyte "B. brasilensis" species. This work assessed the ability of B. kururiensis to endophytically colonize rice plantlets by monitoring different tissues of root-inoculated plants for the presence of bacterial growth in different...
