Abstract

The low productivity of cucumber plants in Indonesia can be caused by several factors, one of which is fertilization. Fertilization on Inceptisol soil which has a low nitrogen content is needed to increase cucumber crop yields. The use of inorganic fertilizers is limited to avoid environmental pollution, so the use of biofertilizers can be an environmentally friendly option. The purpose of this study was to determine the effect of concentration and interval application of azolla extract based biofertilizer on the total soil N, plant N content, Azotobacter population and cucumber yield. The experiment was carried out from August to November 2021 at the Ciparanje Experimental Garden, Faculty of Agriculture, Padjadjaran University. This experiment used a Completely Randomized Block Design of a combination concentrations (0, 5, 10, 15, 20 mL.L-1) and time of application (1, 2, 3 times). The results showed that the application of azolla extract based biofertilizer with different concentrations and application times had a significant effect on the azotobacter population but had no significant effect on soil nitrogen levels, plant nitrogen concentrations, and cucumber yields. The addition of 20 mL/L 2 times application of azolla-based biofertilizer increased cucumber fruit weight by 35.97% compared to control but did not cause a significant increase in yield

Abstract

The use of N2-fixing bacteria and growth hormone-producing rhizobacteria delivers nitrogen, enhances nutrients absorption by plants, and reduces the usage of inorganic fertilizers. Implementing biofertilizer in the hydroponic system as a means to reduce application of synthetic nutrient is recently in interest due to economic, food safety, and sustainability factors. This study determines the effects of biofertilizer dose on tomato yields in the hydroponics system. A randomized block design was utilized that consisted of seven treatments, namely 100% inorganic fertilizer and 0% biofertilizer (control), and various doses of inorganic nutrient combined with 25%, 50%, 75%, and 100% biofertilizer. The result illustrated that the application of biofertilizer augmented the population of endophytic bacteria, Azotobacter sp., Azospirillum sp., phosphate solubilizing bacteria, and nitrogen content. The distinct combination of biofertilizer did not alter the phosphorus and potassium content compared to control samples however resulted in superior tomato grade. The 50% inorganic fertilizer and 100% biofertilizer combination amplified the weight of the fruit by 36% compared to the control. This finding indicates that the application of biofertilizers in the hydroponic system for tomato plants is not only beneficial in minimizing the dosage of inorganic fertilizers but also enhancing the fruit quality.

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

Selecting a carrier material compatible with microbes is crucial for ensuring the quality of biofertilizers. This research aimed to identify a carrier material that could sustain the population of inoculants from dryland (including Delftia tsuruhatensis strain D9, Delftia sp. strain MS2As2, and Bacillus sp.) for a specified period. After conducting the study, it was found that a formulation of 3% molasses, 3% glycerol, 1% potassium sorbate, and 1% Tween-20 enriched with 1% nutrient was the most effective carrier material in maintaining the number of live inoculant cells. This formulation was able to sustain the population of inoculants up to the twelfth week, with a total population of 21.60 × 108 CFU.mL-1 with pH value of media is 5.29, and fulfilled the main criteria for biofertilizers.

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

Farmers usually apply more chemical fertilizers to enhance the yield of strawberries in soilless culture. Humic substances and biofertilizers are now considered essential nutrient sources in sustainable agriculture. The objective of the greenhouse experiment was to observe the effect of humic and fulvic acid (humic substances), and biofertilizer on root growth, nitrogen (N) and phosphor (P) of the growing media, populations of N-fixing and P-solubilizing bacteria in the root zone, and yield of strawberry grown in the cocopeat-based substrate. The experiment was set up in a randomized block design consisting of seven treatments and four replications. The treatments included humic acid, fulvic acid, and biofertilizer in single or combined applications. All data were subjected to analysis of variance and followed by Duncan's Multiple Range Test with p<0.05. All treatments received 50% of the recommended dose of NPK fertilizer. The results showed that all treatments did not affect root length and dry weight. Mixed application of humic substances and biofertilizer together with NPK fertilizer increased total N and P as well as the population of N-fixing bacteria in the growth substrate. Still, P-solubilizing bacteria did not grow in the cocopeat-based substrate. Moreover, mixing humic substances and biofertilizer increased strawberries' fruit yield and sweetness levels.

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.
