Abstract

Hydroponic system is an alternative agricultural cultivation technology and a potential system to overcome the decreasing availability of land. Tomato production with this system has its own market segment. Balanced nutrient management combined with inoculation of functional microbial consortium (N-fixing bacteria and phosphate solubilizers) is one of the efforts to increase tomato production in a hydroponic system. This experiment aimed to examine the effect of microbial consortium and hydroponic nutrition on tomato plant growth, Azotobacter spp. population, N uptake and tomato yield. The research design used was a factorial randomized block design (RBD) consisted of two factors. The first factor was the dose of the microbial consortium, consisting of three levels (0 mL/polybag, 5 mL/polybag, and 10 mL/polybag. The second factor was the nutritional dose consisting of three levels (0 mL, 250 mL, and 500 mL). The experimental results showed that there was no interaction between the microbial consortium treatment nutrients on hydroponic plants’ height, N uptake, Azotobacter spp. population and tomato yield. Increased nutrient dose significantly increased N uptake, with the highest yield at 500 ml/pot. But the increased nutrients dose did not lead to significantly different tomato yields. Inoculation of the microbial consortium did not significantly increase all tested parameters.

Abstract

Inorganic fertilizer is a very important agricultural input to increase agricultural production. Uncalculated and continuous application of inorganic fertilizers will lead to the reduction of soil fertility and degradation of environmental quality. Therefore, a strategy is needed to support the environmental sustainability in agriculture. One of the efforts is through the production of biofertilizer and organic fertilizer from local resources. Organic fertilizer for rice plants can be made by utilizing the local water fern, Azolla pinnata. A. pinnata can be applied on rice fields as green manure by directly placing it into the soil or spread on the surface of rice fields. Organic fertilizer that made from Azolla will be more advantageous because it can be applied with biofertilizer. This study aimed to determine the formulation of Azolla based solid biofertilizer that can support the growth of functional microbial population based on the Agriculture Ministry (Permentan) standard number 70/2011. The design of the study method used was Completely Randomized Design with six replications. The treatments used were inoculant starter with 3% molasses, 3% molasses + 10% rice wash water, 3% molasses + 1% yeast extract, and 3% molasses + 10% rice wash water + 1% yeast extract. The results of this study showed that Azolla-based solids fertilizer with starter formula 3% inoculant molasses + 10% rice water + 1% yeast extract have the population of Azotobacter, Azospirillum, endophytic bacteria and phosphate solubilizing microbe were greater than 108 cfu/g dry weight. Functional microbial of solids fertilizers in all formulas used do not show the difference on inhabiting in the N-free media or Pikovskaya selective media.  Keywords: Azolla pinnata, formulation, biofertilizer, organic fertilize

Abstract

Bioremediation of petroleum waste using the land treatment system is generally carried out by indigenous Petrophilic stimulation as a degrading agent. One of the efforts to improve the performance of the bioremediation system is by adding petrophilic inoculants and organic material as a source of nutrition. This experiment focused on observation of the effect of endogenous petrophilic consortium by adding chicken manure compost towards bioremediation performance parameters, including the efficiency of hydrocarbon degradation, soil pH and petrobacter population on Jatinangor Inceptisols contaminated with petroleum waste. The experiment Design used in this experiment was Factorial Randomized Block Design (FRBD). The first factor was the variation of the concentration  of the petrophilic consortium, consisted of: (i) without a petrophilic consortium, (ii) the concentration of petrophilic consortium 1% (w/ w), (iii) the concentration of petrophilic consortium 3% (w/ w ), (iv) concentration of petrophilic consortium 5% (w/ w). The second factor was the variation of the concentration of chicken manure compost: (ii) without compost chicken manure, (ii) the concentration of chicken manure compost 1.5% (w / w), and (iii) the concentration of chicken manure compost 3% (w/w). ). The results showed that the treatment of exogenous Petrophilic and chicken manure could not significantly improve the biodegradation efficiency of hydrocarbons, but the Petrophilic additives of 3% (w/ w) could increase the highest Petrophilic population. From this study was found that indigenous petrophilic had the potential to degrade hydrocarbons by 71.20%, while the application of exogenous 1% (w/w) petrophilic was able to degrade hydrocarbons by 71.97 %.

Abstract

The growth and yield of rice plants is very dependent on nitrogen (N) fertilizer. N fertilizer applied to wetland rice mostly unutilized due to the lost through the process of denitrification and leaching. The presence of blue-green algae (BGA), procaryotic algae N2-fixing in the paddy field is advantageous to help to uptake the N for plants by direct fixation of N2 from air and then converted into cell proteins. Excess N fixation results were released into the BGA growth environment. BGA biomass at the latter stage will be mineralized to ammonium. Mineralized ammonium from BGA cells as a source of N that can be used directly by paddy plants. This experiment used a randomized block design with factorial pattern; BGA inoculant dose treatment consisted of: 0; 5 kg; 10 kg ha-1 and urea dose 30; 60; 90; 120 kg N ha-1. The results of this experiment showed that the use of BGA can increase the rate of growth of rice plants and reduced urea requirements by 25%. The combination of 90 kg ha-1 N fertilizer with 10 kg ha-1 Blue-green algae inoculant can increase grain yield by 31.47% per hectare (2.71 tons ha-1).

Abstract

The use of inorganic fertilizers for a long term can reduce soil fertility. One of the alternatives solving this problem is by using solid biofertilizers. Solid biofertilizer requires carrier materials that can support the viability of potential microbial within. Azolla pinnata is one of the carriers that has potential as a substitute for commonly used carrier materials. This study aims to determine the effect of Azolla pinnata and other organic materials with inoculant dosage on viability of bacterial population, N-total, P-total of solid biofertilizer. This research was conducted at Soil Biology Laboratory, Department of Soil Science, Faculty of Agriculture, Padjadjaran University in January-February 2015. The treatments were organic matter (Azolla pinnata, litter compost and peat) with various dosages of bacterial inoculant (20%, 25% 30%). This experiment used the Completely Random Design with factorial pattern. The main observations of the study were analyzed by ANOVA test and continued with Duncan test with 5% confidence level. The results showed that Azolla pinnata carrier has significantly effect to the increase of N-Total and P total of solid biofertilizer. The inoculant dosage of 30% affects the population increase of Azotobacter sp., and endophytic bacteria, but does not effect to the population of Phosphate Solubilizing Bacteria and Azospirillum sp. Azolla pinnata can be recommended as an alternative carrier that can replace peat and litter compost materials.The results of this study was illustrate Azolla pinnata can be recommended as an alternative carrier for solid biofertilizer that can replace peat and litter compost material with 30% inoculant dosage.Keywords: Azolla pinnata compost, litter, peat, solid biofertilizer
