Publisher : Brawijaya University

Objective of the research was to study the effect mycorrhiza on growth and yield of tomato. The experiment was conducted in screen house 14 m x 10.5 m, in Pasuruan on November 2013 until March 2014, The experiment was conducted as a factorial randomized complete design. The first factor was dose of mycorrhiza (without mycorrhiza, 5 g mycorrhiza, 10 g mycorrhiza, and 20 g mycorrhiza). The second factor was the salinity stress level (without NaCl, 2500 ppm NaCl, 5000 ppm NaCl, and 7500 ppm NaCl). The results showed that salinity stress at the level 7500 ppm decreased the amount of fruit by 30.84% and fresh weight per hectare decreased by 51.72%. Mycorrhizal application was not able to increase the growth and yield in saline stress conditions; it was shown by the level of infection and the number of spores on the roots of tomato plants lower the salinity level 5000 ppm and 7500 ppm. But separately, application of 20 g mycorrhiza enhanced plant growth, such as plant height, leaf area, leaf number and proline. Application of 20 g mycorrhiza increased the yield by 35.99%

This study aimed to analyze the effect of Tithonia diversifolia green manure and cow manure on soil quality and yield of cauliflower. A field experiment was conducted in the village of Tegalgondo, Karangploso District of Malang Regency. Eight treatments tested were control (no added manures), T.diversifolia 8.15 t/ha, cow manure 25.85 t/ha, NPK fertilizer 1.35 t/ha, T.diversifolia 4.08 t/ha + cow manure 12.93 t/ha, T.diversifolia 4.08 t/ha + NPK fertilizer 676 kg/ha, cow manure 12.93 t/ha + NPK 676 kg/ha and T.diversifolia 2.69 t/ha + cow manure 8.53 t/ha + NPK fertilizer 446 kg/ha. Soil quality was monitored at top soil (0-20 cm) at planting time and 30 days after planting. Soil samples were collected and analyzed for chemical and physical properties. Yield of cauliflower was observed at the time of harvest or 44 days after planting. The results showed that application of green manure could significantly change the physical and chemical properties of the soil. The decrease of bulk density of about 27.47%, increase of organic carbon of about 12.60%, increase of total N of about 53.87%, increase of available P of about 64.24 mg/kg, and exchangeable K of about 8.34 cmol/kg were observed in T. diversifolia treatment. The increase of pH of about 1.75%, and total porosity of about 17.73% was found in cow manure treatments. The increased water holding capacity of about 10.70% was found in T. diversifolia + cow manure treatments and increased stability aggregate about 23.54% was found in T. diversifolia + cow manure + NPK treatments. There was a significant increase of fresh weight of flower about 666.67 g/plant in T. diversifolia + NPK treatment.

Publisher : Brawijaya University

Soil salinity has negative effect on soil biodiversity as well as microbial activities. Hence, rice growth also effected by salinity. Application of organic fertilizer and adoption of System of Rice Intensification (SRI) cultivation might improve the (biological) soil properties and increase rice yield. The aim of this study was to evaluate the effect of two different rice cultivation methods namely conventional rice cultivation method and System of Rice Intensification (SRI) rice cultivation method and two kinds organic fertilizer on improvement of soil biological properties and rice yield. In this study, a split plot experimental design was applied where rice cultivation method (conventional and SRI) was the main plot and two kinds of organic fertilizer (market waste and rice straw) was the sub plot. The treatments had four replicates. The results showed that SRI cultivation with market waste organic fertilizer could increase soil biological properties (population of microbe, fungi and soil respiration). The same treatment also increased rice growth and production. Combination of SRI and market waste organic fertilizer yielded the highest rice production (7.21 t/ha).

Publisher : Brawijaya University

Cocoa is one of plantation commodities that is quite important for the national economy. Land management for the development of this plant should pay attention to the characteristics of the soil. Three soil profiles formed from alluvium parent material in East Kolaka Regency were investigated to determine the mineralogical, physical, and chemical soil properties, as well as the potential of the land for the development of cocoa plant. The results showed that the mineral composition of the sand fraction was dominated by quartz, while the clay mineral fraction was composed of kaolinite, hydrate halloysite, interstratified of illite-vermiculite and smectite. The soils were characterized by poor drainage, low bulk density (0.78 to 0.95 g / cm3), moderate available water pores (10-15%), slow to fast permeability (0.10 to 14.05 cm / h), silty clay loam to silty clay texture of top soil, acidic soil reaction (pH 4.62 to 5.47), high organic C content (3.86 to 4.60%) in the top soil and very low organic C content (<0.65%) in the lower layer, moderate to high available P (14-38 mg / kg) in the A horizon and very low to moderate (1-18 mg / kg) in horizon B, moderate to high P2O5 (30-71 mg / 100g) in horizon A and extremely low (1-11 mg / 100g) in horizon B, very low to moderate K2O (3-28 mg / 100g ), moderate to high exchangeable Ca (9.32 to 13.92 cmolc / kg) in the upper and lower (0.70 to 5.04 cmolc / kg) in the bottom layer, high exchangeable Mg content (2.83 to 8.95 cmolc / kg), high soil CEC (34.18 to 38.28 cmolc / kg) in the upper layer and low to moderate (7.87 to 20.39 cmolc / kg) in the bottom layer, moderate to high base saturation (44-68%), and very low to moderate Al saturation (0-17%). At the family level, the soil was classified as Fluvaquentic Endoaquepts (EK 1 profile) and Typic Endoaquepts (EK 2 and EK 3 profiles), finely loamy, mix, acid, isohypertermik. The land was marginally suitable (S3) for cocoa plant with the contraints of impeded drainage, acid soil reaction, and low K2O. Drainage channel management can be done to increase the carrying capacity of the land for the development of cocoa plant.

The aim of this research was to study the influence of P. fluorescens and sulfur on nutrients uptake, growth and yield of groundnut in alkaline soil. The experiment was conducted in the greenhouse in Malang from January 2015 to Mei 2015. The experiment was laid out in factorial randomized block design consisted of two treatment factors and three replications. The first factor were concentration of P. fluorescens (0 cfu/mL; 107 cfu/mL; and 109 cfu/mL). The second factor were elemental sulfur doses (0 g/kg soil; 1 g/kg soil; 2 /kg soil; and 3 g/kg soil). Soil used was collected from Lamongan East Java, Indonesia. Soil previously was given 40 g Ca(OH)2 /kg soil to achieve pH >8. There was no interaction between P. fluorescens and sulfur on all of parameters observed. P. fluorescens concentration of 109 cfu/mL independently significantly increased availabe Fe in soil as 34.75% compared with the control and could maintain the populations of P. fluorescens better than the concentrations of 0 and 107 cfu/mL. Sulfur significantly correlated with decrease in soil pH expressed by equation y = -0,226x + 8.218. Sulfur independently significantly increased N, P, S, Ca and Mn uptake by plants. Sulfur dose of 3 g/kg of soil provided leaves and stems growth better, increased 80.74% of pod yield and 34.09% of harvest index compared to control.

Publisher : Brawijaya University

This study was aimed to identify the impact of small-scale gold processing activities on mercury content in wetland rice soil and water during the rainy and first dry seasons in Central Lombok and West Lombok Districts. The method used for this study was survey method. Measurement of mercury levels in water samples was conducted at Agro Bogor Centre using SNI 6989.77: 2011methods. The data was collected and processed in a simple statisticpresented descriptively, in order to obtain information. Results of the study showed that mercury content soils in the rainy season exceeded the threshold of 0.005 ppm, while in the first dry season the mercury content in soil decreased, but it was still above the threshold value permitted. The contents of mercury in water samples in the rainy season and the first dry season were still at a safe point that was less than 0.05 ppm. The wetland rice soil and water had been polluted with mercury, although the mercury content in the water was still below the threshold, but the accumulation of mercury that could have been absorbed by the plants are of particular concerns. The decrease of mercury content in soil in dry season was due to lack of gold processing activities.

A study that was aimed to identify the impact of forest fires on the biological properties of soils was carried out at former forest fire areas in Samosir Regency of North Sumatera. Soil samples were collected from former forest fire areas of 2014, 2013, 2012, 2011, 2010. The composite soil samples were collected systematically using diagonal method as much as 5 points in each period of fire. The soil samples were taken at three plots measuring 20 x 20 m 0-20 cm depth. Soil biological properties observed were soil organic C content, total number of microbes, abundance of arbuscular mycorrhizal fungi, phosphate solubilizing microbes, and soil microbial activity. The results showed that organic C content ranged from 0.75 to 2.47% which included criteria for very low to moderate. Arbuscular mycorrhizal fungi spores were found belonging to the genus of Glomus and Acaulospora. Spore number increased with the fire period ranging from 45 spores (forest fire in 2014) to 152 spores (forest fire in 2010). The total number of microbes obtained ranged from 53.78 x 107 cfu/mL (forest fire in 2010) to 89.70 x107 cfu/mL (forest fire in 2013). It was found 29 isolates of phosphate solubilizing microbes that consisted of 14 bacterial isolates and 15 fungi isolates with densities ranging from 27.642 x105 cfu/mL (forest fires in 2014) to 97.776 x 105 cfu/ mL (forest fires in 2011). The isolates of phosphate solubilizing bacteria identified consisted of Pseudomonas, Flavobacterium, Staphylococcus, and Mycobacterium genus, whereas the isolates of phosphate solubilizing fungi obtained consisted of Aspergillus and Penicillium genus. Soil respiration ranged from 2.14 kg / day (forest fire in 2010) up to 3.71 kg / day (forest fire in 2013). The varied results were greatly influenced by the type or form of the fires and intensity of fires. In the study area the type or form of the fires were canopy fires with low intensity.

There are about 23% waste oil palm empty fruit bunches (OPEFB) of total waste generated from the production of crude palm oil in oil palm plantations. Pyrolysis technology can be used to convert waste into biochar and further can be utilized for the improvement of soil. Biochar-microbes of OPEFB are biochar from OPEFB biomass that enriched with soil microbes. Biochar-microbes is expected to be used for the improvement of the soil and plants. Therefore the purpose of this research was to study the ability of biochar-microbes OPEFB to increase availability of the nutrients in sandy soils. The process of making biochar done by using slow pyrolysis technology by heating 300oC and 400oC for 2 and 3 hours, and with sizes 40 and 80 mesh, as well as indigenous microbial Bulkhorderia nodosa G.52.Rif1 and Trichoderma sp.) added. The biochar production and research were conducted in the Department of Forestry Laboratory and in the Department of Agronomy Laboratory, Faculty of Agriculture, Palangka Raya University. In general, the study showed that biochar-microbes could maintain the soil pH value and tends to increase the soil pH, increasing the holding capacity of sandy soil to the elements of P and K as well as increasing the availability of nutrients N, P and K. Furthermore, this study showed that the biochar process by 400oC heating for 3 hours and 40 mesh with microbes or without microbes were the best effect on the improvement of the quality of holding capacity and the nutrients supply in sandy soils.

A study that was aimed to explore the effects of arbuscular mycorrhizal (AM) fungi inoculation on the potential of wild plant species (Paspalum conjugatum, Cyperus kyllingia, and Lindernia crustacea) for phytoextraction of mercury from small-scale gold mine tailings was conducted in a glasshouse. Each of the plant seedlings was planted in a plastic pot containing 10 kg of planting medium (mixture of tailings and compost; 50%: 50% by weight). Treatments tested were three plant species and doses of AM fungi inoculation, i.e. 0 and 30 spores/plant. At harvest of 63 days, plant shoot and root were analyzed for mercury concentration. The remaining planting media in the pots were used for growing maize for 84 days. The results showed that the most potential plant species for phytoextraction of mercury was Paspalum conjugatum, while the most mercury tolerant plant was Cyperus kyllingia. Without AM fungi inoculation, the highest accumulation of mercury (44.87 mg/kg) was found in the root of Paspalum conjugatum. If AM fungi were inoculated, the highest accumulation of mercury (56.30 mg/kg) was also found in the shoot of Paspalum conjugatum. Results of the second experiment proved that the growth and biomass production of maize after mycophytoextraction by the plant species were higher than those of maize grown on media without mycophytoextraction of mercury.

This study was aimed to determine the effect Petrophilic and Azotobacter sp. consortium on the rate of degradation of hydrocarbons, Azotobacter growth, and Petrophilic fungi growth in an Inceptisol contaminated with crude oil waste originating from Balongan refinery, one of Pertamina (Indonesia’s largest state-owned oil and gas company) units in Indramayu – West Java. This study was conducted from March to April 2014 in the glasshouse of research station of the Faculty of Agriculture, Padjadjaran University at Ciparanje, Jatinangor District, Sumedang Regency of West Java. This study used a factorial completely randomized design with two treatments. The first treatment factor was Petrophilic microbes (A) consisting of four levels (without treatment, 2% Petrophilic fungi, 2% Petrophilic bacteria, and the 2% Petrophilic consortium), and Azotobacter sp. The second treatment factor was Azotobacter sp. (B) consisting of four levels (without treatment, 0.5%, Azotobacter sp., 1% Azotobacter sp., and 1.5% Azotobacter sp.) The results demonstrated interaction between Petrophilic microbes and Azotobacter sp. towards hydrocarbon degradation rate, but no interaction was found towards the growth rate of Azotobacter sp. and Petrophilic fungi. Treatments of a1b3 (2% consortium of Petrophilic fungi with 1.5% Azotobacter sp.) and a3b3 (2% Petrophilic consortium and 1.5% Azotobacter sp.) had hydrocarbon degradation rate at 0.22 ppm/day for each treatment, showing the highest hydrocarbon degradation rate.
