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.

Abstract

Attempt to increase soybean production while maintaining soil health can be done by utilizing biofertilizers. However, the application of biological fertilizers on Inceptisols which tend to be acidic often go to meet the problems in its effectiveness. So it is necessary to maintain the effectiveness of inoculants through the selection of appropriate carrier materials. The experiment aimed to determine the effect of the application of Phosphate Solubilizing Bacteria (PSB) in carrier materials from agricultural waste (molasses, coconut water, and bran) to increase BPF viability, growth and yield of soybean (Glycine max L.) on Inceptisols in Jatinangor. The experimental design used was a randomized block design (RBD) consisting of a control treatment (without BPF inoculant), BPF without organic matter; BPF combined with three types of organic matter (each: molasses, coconut water, and rice bran and their mixtures). Experimental results showed that coconut water and rice bran could potentially maintain the viability of the BPF population. Coconut water could significantly increase the number and weight of seeds per soybean plant, with an increase in yield of 41.176% and 18.823%, respectively. Coconut water is an organic substance that has the most potential as a stimulant  material compared with molasses or bran.ABSTRAK Upaya untuk meningkatkan produksi kedelai sekaligus mempertahankan kesehatan tanah dapat dilakukan dengan memanfaatkan pupuk hayati (biofertilizers). Namun aplikasi pupuk hayati pada Inceptisol yang cenderung masam sering mengalami kendala dalam efektifitasnya. Sehingga perlu upaya untuk menjaga efektifitas inokulan melalui pemilihan bahan pembawa yang tepat. Percobaan ini bertujuan untuk mengetahui pengaruh aplikasi Bakteri Pelarut Fosfat (BPF) dalam bahan pembawa dari limbah pertanian (molase, air kelapa, dan dedak) untuk meningkatkan viabilitas BPF, pertumbuhan dan hasil tanaman kedelai (Glycine max L.)  pada Inceptisols di Jatinangor. Percobaan dilakukan di rumah kaca kebun percobaan Fakultas Pertanian Unpad. Rancangan percobaan yang digunakan adalah Rancangan Acak kelompok (RAK) yang terdiri dari perlakuan kontrol (tanpa inokulan BPF), BPF tanpa bahan organik; BPF dikombinasikan dengan tiga jenis bahan organik (masing-masing: molase, air kelapa, dedak padi,  dan campurannya). Hasil percobaan menunjukkan bahwa air kelapa dan dedak padi berpotensi dapat mempertahankan viabilitas populasi BPF. Air kelapa dapat meningkatkan jumlah dan bobot biji per tanaman kedelai secara signifikan, dengan peningkatan hasil masing-masing sebesar 41,176% dan 18,823%. Air kelapa merupakan bahan organik yang paling potensial sebagai bahan stimulan dibandingkan molase maupun dedak. Air kelapa mengandung glukosa, fruktosa, dan sukrosa, asam glutamat dan asam aspartat yang dapat berperan dalam memacu aktifitas BPF.

Abstract

The Inoculation of beneficial soil microbes is an effective method for lowering doses of inorganic fertilizers. This study was aimed to observe and compare the effect of doses and formulas of Bacillus-coated NPK (BCN) and conventional NPK fertilizers on biomass, major macro-nutrient in soil and their uptake by shoots of lettuce (Lactuca sativa L.); as well as evaluate the potency of BCN for decreasing doses of NPK fertilizers. The greenhouse experiment was set up in a randomized block design with seven treatments and five replications. The treatments included one and a half doses of recommended NPK fertilizer and two BCN fertilizer formulas; control treatment was without any fertilizer. This experiment showed that NPK fertilizer had comparable effect with BCN on growth traits; but application of NPK and coated NPK had a potency to increase the fresh weight of lettuce up to 24-45% which was in line with the increase of shoot-to-roots ratio. The potassium (K) content in soil and their uptake in lettuce shoots depend on doses and type of NPK but Nitrogen (N) and Phosphorus (P) content in soil and in shoot were not determined by treatments. The results showed that the recommended NPK dose (200 kg/ha) for lettuce can be reduced up to 50%; moreover, 50% of BCN enabled to maintain the N, P and K uptake as well as the lettuce yield.

Abstract

This study aims to determine the effect of the C/N ratio of a mixture of dairy cow dung and kirinyuh leaves on the quality of extraction or Liquid Organic Fertilizer (POF). The treatment consisted of a mixture of dairy cow manure and kirinyuh leaves with different C/N, namely P1=16, P2=18, P3=20, P4=22. The treatment was decomposed for 14 days then extracted and incubated for 14 days. Observations included a decrease in C-organic content (%), total N-total (%), C/N ratio, P content (%), K content (%), the number of P-solvent bacteria (CFU/ml), Azosprillium (CFU/ ml) and Azotobacter (CFU/ml). The results showed that the effect of the C/N ratio only had a significant effect on the N parameter of composting where the best results were seen at a C/N ratio of 16. Meanwhile for the POC quality the parameters C, N and P had no significant effect, while for K parameter, total of P solubilizing bacteria, Azosprillium and Azotobacter had a significant effect. The highest levels of K and the total of Azotobacter were found at the initial C/N ratio of 16. Meanwhile, the highest total of P-solubilizing bacteria and the highest total of azosprillium were found at the initial C/N ratio of 22. Therefore an initial C/N ratio of 16 is recommended for composting dairy cow faeces. with kirnyuh leaves. While the extraction results are recommended to be focused on making biological fertilizers.

Abstract

Artisanal and small-scale gold mining has commonly used the mercury amalgamation method for gold ore extraction. The processing waste or tailings often contain gold and other metals. This study examined the effects of cow manure amendment and the ratio of gold mine tailings on sweet potato     (Ipomoea batatas L.) gold phytomining. The pot experiment was conducted in the Faculty of Agriculture greenhouse at Padjadjaran University in Indonesia. The sweet potato MZ119 clone (an orange-fleshed sweet potato) was planted on a polybag (40 x 40 cm) consisting of 10 kg of planting media, which was a mixture of gold mine tailing and soil. The design used was a completely randomized design factorial with three replications. The first factor was ratios of gold mine tailing consisting of three levels, namely 30%, 50%, 70%, and 100% (w/w). The second factor was doses of organic manure, namely without cow manure, 250 g pot-1, 500 g pot-1, and 750 g pot-1. The results demonstrated that the application of cow dung and the gold mine tailings ratio (w/w) had a significant (p = 0.05) effect on plants' dry weight biomass, gold accumulation, and gold phytomining by sweet potato. The highest gold mass yield of 0.066 mg gold plant-1 was achieved by a 50% (w/w) gold mine tailing ratio and 750 g pot-1 cow manure treatment.

Abstract

The Nutrient Film Technique (NFT) in hydroponic crop production systems generally uses chemical nutrient solutions to provide plant nutrients, even though biofertilizer inoculation can enrich liquid nutrients. The purpose of this experiment was to observe the effect of liquid biofertilizers applied with chemical nutrient solutions on changes in the acidity and electrical conductivity of nutrient solutions, as well as the growth and yields of pak choy (Brassica rapa L.) grown in Nutrient Film Technique. This experiment was set up in a completely randomized design with three nutrient solution treatments and eight replications. The treatments included the application of 100% chemical nutrient solution (control), and 75% and 50% concentrations of chemical nutrient solution enriched with a consortium biofertilizer. The results showed that at the end of the experiment, the acidity of all nutrient solutions increased, but their electrical conductivity (EC) was reduced. The fresh weight of pak choy shoots in medium B (75% chemical nutrition with biofertilizers) was 34% lower than the control (A), although statistically it was not significant. However, 50% chemical nutrition with biofertilizers produced the same shoot weight as the recommended dose of chemical nutrition. Moreover, 75% chemical nutrient with biofertilizers increased root weight. This current experiment verified that a reduced concentration of nutrient solution enriched with biofertilizer can be used to maintain the yield of pak choy grown in NFT.
