Abstract

Saline soil contain excessive NaCl content which inhibit plant growth and lead to nitrogen deficiency. Endophytic bacteria live inside the plant tissue and has the ability to fix nitrogen directly from the atmosphere, meanwhile Azolla pinnata can be used as organic ameliorant that able to increase the number of availability nitrogen for plant in soil, and improve the physical, chemical, and biological properties of soil. The aims of this experiment were to find out the treatment that cause highest nitrogen uptake by plant, total-N of soil, and dry weight of rice in saline soil. The experimental design was randomized block design with eight treatments and four repetitions. The results showed that the application of biofertilizer and ameliorant increased nitrogen uptake by plant and dry weight of rice in saline soil, but there was no significant effect on  total-N of soil. This experiment suggested that endophytic bacteria biofertilizer and Azolla pinnata were effective to increase dry weight and nitrogen uptake of rice grown in soil with EC between  2 dS m-1 - 4 dS m-1.

Abstract

This study aims was to determine the potential of water fern Azolla pinnata combined with biofertilizer (Azotobacter chroococcum N2-fixing bacteria and Pseudomonas cepaceae phosphate solublelizing bacteria) in improving N and P content of the soil, and yield of paddy rice crops. This research was conducted in lowland Sanggar Penelitian Latihan dan Pengembangan Pertanian (SPLPP), Ciparay Bandung regency. The experimental design used was randomized block design with factorial pattern that consists of two factors. The first factor that A. pinnata (A) consists of two levels, without A. pinnata and A. pinnata with as 3 tons ha-1. The second factor is the biological fertilizer (H) consists of 3 levels with doses of 0, 5, and 10 L ha-1. The results showed A. pinnata and biofertilizer do not interact to increased soil N and P, as well as lowland rice crops. However, A. pinnata independently can increase the content of available N and P soil, while the biofertilizer 10 L ha-1 is able to increase the available soil-P content compared with controls. The combination of A. pinnata and biofertilizers have not been able to increase the yield of rice significantly, but can increase the yield of rice by 16.1 % compared to the average yield of rice in paddy field locations in Ciparay Bandung regency

Abstract

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

Abstract

This study aimed at comparing the effec­tiveness of consortium bio-fertilizer with endo­phytic bio fertilizer to increasing produc­tivity and health of mature clone GMB 7 tea crop. This research was carried out at the Gambung Experimental Station Block A7 Research Insti­tute for Tea and Cinchona, from July 2013 to September 2013. Randomized block design was used in this study with ten treatments and three replications i.e.: A1H0 = anorganic fertilizer (75%), A2H0 = anorganic fertilizer (50%), A1H1 = anorganic fertilizer (75%) + 2 liter consortium bio fertilizer, A1H2 = anorganic fertilizer (75 %) + 4 liter consor­tium bio-ferti­lizer, A2H1 = anorganic fertilizer (50 %) + 2 liter consortium bio fertilizer, A2H2 = anorga­nic fertilizer (50%) + 4 liter consor­tium bio-fertilizer, A1H3 = anorganic fertilizer (75 %) + 2 liter endophytic bio fertilizer, A1H4 = anor­ganic fertilizer (75%) + 4 liter endo­phytic bio fertilizer, A2H3 = anorganic fertili­zer (50%) + 2 liter endophytic bio fertilizer and A2H4 = anorganic fertilizers (50%) +4 liter endophytic bio fertilizer. The results showed there were a significantly difference on amount of the pekoe shoot among treatments, although the others variable was not significantly diffe­rent. However, the overall consortium bio-fertilizer resulted in the production of shoots 15,36% and endophytic biofertilizer application resulted in the production of shoots 21,93% higher than the control (without bio fertilizer). When compared to the first plucking, the num­ber of shoot from July to September showed increasing trend, so did the number of banji shoots.

Abstract

The chemical control method of blister blight (Exobasidium vexans Massee) on tea could inflict various negative impacts. In order to obtain an environmentally sound control method of blister blight disease, a nursery trial has been conducted to know the effectiveness of bacterial combinations. The trial was carried out at Gambung experimental garden, with seven treatments and four replications. The indigenous microbial codes are Azoto II-1, Endo-5 and Endo-76. The treatments tested comprised: control (without bacteria),  Azoto II-1 25% + Endo-5 75%; Azoto II-1 50% + Endo-5 50%; Azoto II-1 75% + Endo-5 25%;  Azoto II-1 25% + Endo-76 75%; Azoto II-1 50% + Endo-76 50%; and Azoto II-1 75% + Endo-76 25%. All of the treatments was applied as a soil drench, 50 ml/plant with bacterial concentration at 0,5%. The parameter observed was blister blight disease intensity, plant heights, stem diameter, leaves number, root length, and root volume. The results showed that the combination of Azoto II-1 75% + Endo-5 25% could suppress the intensity of blister blight disease with disease intensity 1.27%. The treatments also affected plant heights, stem diameter, leaves number, root length, and root volume, 15.32 cm; 3.38 cm; 8.05 cm; 18.25 cm and 2.37 cm, respectively.

Abstract

Tea was planting an upland area with Andisol as the dominant soil ordo. Andisol has a special characteristic i.e. low soil pH and it has more mineral that causing low of soil phos-phate soluble, especially for tea plants, there-fore the rule of solubilizing phosphate bacteria will be needed. Laboratory scale experiments were conducted to study the capability activities of some solubilizing phosphate bacterias name-ly Pseudomonas cepaceae, P. malei, Bacillus mycoides, and B. subtilis. The experiment was arranged in Completely Randomized Design with six treatments and four replications. The result on statistical analysis shown that there were no significant differences in increasing of the soil phosphate soluble. Nevertheless, the treatment D (Bacillus mycoides) produced the highest soil phosphate soluble. The capability of bacteria to increase soil phosphate soluble was depended on its habitat, especially soil pH. Even all of the isolates were the superior solubilizing phosphate bacterias in agricultural food plants with neutral soil pH, but they have not significantly different on Andisol. There-fore, the using of indigenous isolates on tea plant areas was suggested.
