Abstract

Utilization of saline land as an effort to increase rice productivity is still constrained by the adverse effects of salinity stress. The solution to this effort can be done by utilizing PGPR biofertilizers and applying ameliorant briquettes. The purpose of this study was to evaluate the effect of using biofertilizers and ameliorant briquettes on saline soils with various levels of salinity on the growth of rice plants. This research was conducted at the Ciparanje Jatinangor screen house from September 2022 to January 2023. The research design used was a randomized block design with 12 treatments and 3 replications. The treatment applied was PGPR biofertilizer, ameliorant briquettes, and their combination on saline soil 4 and 8 dS m-1 compared to control (non-saline soil). The results showed that PGPR biofertilizer increased the height of rice plants on saline soils 4 and 8 dS m-1 7 DAP. At 14 DAP, PGPR biofertilizer, ameliorant briquettes, and their combinations did not increase rice plant height, root length and volume, wet weight, and dry weight of rice plants, although the application of biofertilizers, ameliorant briquettes, and their combinations tended to increase wet weight and dry weight of rice plant compared to soil with the same salinity without biofertilizers and ameliorant briquettes.

Abstract

Biofertilizers contain bacteria that can offset the use of inorganic fertilizers. However, using bacteria as biofertilizers also requires carrier materials such as bran, compost, and Azolla flour to maintain the viability of the bacteria before being transferred to the soil. This study aimed to determine the effect of consortium biofertilizer with different carriers and doses of NPK (nitrogen, phosphorus, potassium) fertilizer on the growth and yield of upland rice on Inceptisols from Jatinangor. This study used a randomized block design with two factors: the carrier of consortium biofertilizer (compost, rice bran, and Azolla) and the dose of NPK fertilizer (0%, 50%, and 100%). The experimental results showed no interaction between the consortium's biofertilizers with carrier and NPK fertilizer doses on plant height, number of tillers, weight of rice grain, and weight of 100 grains of upland rice plants. The independent factor of biological fertilizer with carrier material significantly affected plant height, and the independent factor of single NPK fertilizer significantly affected plant height, number of tillers, and rice grain weight.

Abstract

The status of nutrients N, P, and soil organic content in corn cultivation is an important thing that needs to be pursued to improve soil quality. One such effort is through mycorrhizal inoculation and the application of appropriate compost. The aim of this study was to evaluate the effectiveness of arbuscular mycorrhizal fungi (FMA-1) and compost types on soil chemical properties (C/N, C/P), degree of root infection, and corn pruning weight (Zea mays) on Inceptisols. The experiment used three replications of a factorial randomized block design (RBD). The first factor of FMA inoculation: FMA 0 gpot-1, FMA-1 20 g/pot; Mycofer 20 g/pot, and mix (FMA-1 10 g/pot + FMA mycofer 10 g/pot), and the second factor is compost application: 0 g/pot; 75 gpot-1 rabbit hutch compost; 75 g/pot market waste compost and rabbit cage compost 37.5 g/pot + market waste compost 37.5 g/pot). The results showed that there was no interaction between AMF inoculation and the application of compost which affected soil chemical properties, degree of root infection, and dry weight of corn plants. However, independently AMF affects the degree of root infection, and compost affects the dry weight of corn plants. A dose of 20 g/pot FMA and mixed FMA inoculation (FMA and Mycofer) significantly increased the degree of root infection compared to the control treatment. The application of all types of compost showed a significant increase in corn plant dry weight compared to the control. Doses of 75 g/pot of market waste compost tended to increase plant dry weight higher than other treatments with an addition of 32.07 g each plant.

Abstract

The need for adequate nutrition for organic rice cultivation is very important. It is necessary to look for various sources of nutrients apart from organic fertilizers from rice straw compost and manure. Azolla water ferns and solid or liquid biofertilizers shoud be used as an alternative in the way to increase plant nutrients in organic rice cultivation in paddy fields. This experiment aims to increase the yield of lowland rice plants which are cultivated organically for the first time through the application of organic fertilizer enriched with azolla and biofertilizers in the lowland rice fields of Inceptisols Jatinangor. The experiment was carried out at the Experimental Garden, Ciparanje, it’s belong to Faculty of Agriculture, Universitas Padjadjaran, Sumedang, West Java. The design used was a Randomized Block Design (RBD) with six treatments, namely organic fertilizer, organic fertilizer + Azolla, organic fertilizer + solid biofertilizer, organic fertilizer + Azolla + solid biofertilizer, organic fertilizer + liquid biofertilizer, organic fertilizer organic + Azolla + liquid biofertilizer. Each treatment repeated four times. The experimental results showed that the application of a combination of organic fertilizers and biofertilizers had an effect on lowland rice yields but had no significant effect on plant N content and N uptake of lowland rice plants in Inceptisols Jatinangor.

Abstract

An in-vitro experiment to evaluate total nitrogen content of soil of tea plantation area included with indigenous and exogenous Azoto­bacter sp have been conducted in the Biology and Soil Biotechnology Laboratory, Padja­djaran University. A completely randomized design with 11 treatments and three repli­cations was used. The treatments were: A (ne­gative control); B (positive control); C (A. Kedelai II); D (A. vinelandii); E (A. N.D.9.3); F (A. Padi); G (VI-1); H (II-1); I (V-2); J (I-1); and K (III-2). Size of microbe inoculated popu­lation for each treatment was 1,2 x 1011 CFU/ml. One percent dose was used for ste­rilized soil originated from the tea plantation area. After five days of incubation period re­vealed that II-1 Azotobacter sp produced very significantly different in total nitrogen pro­duction than the other Azotobacter sp, i.e. 0,8532%. Orthogonal comparisons indicated that indigenous Azotobacter sp had the capacity of nitrogen fixation 7,67% higher than that the capacity of nitrogen fixation of exogenous Azotobacter sp for growth on Andisol soil of tea plantation area with pH of 4,5-5,6. Although, Azotobacter sp is very rarely found in soil with low pH (high acidity), this phenomena indi­cating that an active biofertilizer of indigenous Azotobacter sp is present in tea plantation area.

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.

Abstract

Penggunaan lahan pertanian dengan status hara kurang optimal dapatmenghambat pertumbuhan tanaman, sehingga perlu upaya penambahan unsur hara ke dalam tanah tanpa menyebabkan permasalahan lingkungan. Salah satu cara yang dapat dilakukan adalah dengan memberikan pupuk organik berupa kompos. Melimpahnya volume limbah pertanian dapat dimanfaatkan sebagai bahan baku pembuatan kompos. Penelitian ini bertujuan untuk mengetahui pengaruh dari berbagai jenis kompos limbah pertanian dengan taraf dosis yang berbeda terhadap populasi Azotobacter sp., C-organik, N-total, Serapan-N, dan hasil pakcoy (Brassica rapa L.) pada tanah Incepstisol Jatinangor. Penelitian dilaksanakan di rumah kaca kebun percobaan Ciparanje, Kecamatan Jatinangor menggunakan Rancangan Acak Kelompok dengan 10 perlakuan tiga ulangan. Perlakuan terdiri dari: satu kontrol dan tiga taraf dosis dari setiap jenis kompos. Jenis kompos yang digunakan adalah kompos jerami padi, ampas tebu, dan tandan kosong kelapa sawit. Hasil penelitian menunjukkan bahwa pemberian kompos limbah pertanian berpengaruh nyata terhadap total populasi Azotobacter sp. dan hasil pakcoy. Parameter C-organik, N-total dan Serapan-N tidak berbeda nyata antar perlakuan dan kontrol. Pemberian kompos jerami padi 20 ton/ha merupakan perlakuan terbaik dalam menghasilkan 130,97 g bobot basah dengan 8,46 g bobot kering per tanaman pakcoy. Pemanfaatan limbah pertanian dapat menjadi alternatif yang ramah lingkungan dalam meningkatkan hasil tanaman pakcoy, walaupun hasil penelitian ini belum berpengaruh nyata terhadap C dan N.
