Abstract

Growth and production of corn plants require land with sufficient nutrients. Utilization of biological fertilizers and organic materials carried out with the aim of increasing the yield of corn. The treatments that were tried were the provision of compost, livestock manure, compost and livestock manure, each of which was added by spraying a consortium of biological fertilizer. The experiment was designed using a randomized block design with five replications. The results showed that the application of organic-based fertilizers affected plant height from 17 - 49 days after planting, weight of fruit with kelobot, weight of cob and ear length. Provision of compost or livestock manure and added with a biological fertilizer consortium by spray gives a higher effect compared to the provision of compost or livestock manure which is not added to the consortium of biological fertilizer. To increase the productivity of maize plants it is recommended to use a consortium of biological fertilizers applied by spraying at intervals of seven days until the plants are 49 days after planting.

Abstract

Consortium biofertilizer containing Nitrogen (N) Fixing Bacteria and Phosphate (P) Solubilizing Bacteria may substitute inorganic fertilizer in vegetable production. A greenhouse experiment was conducted to evaluate the effect of some combinations and doses of consortium biofertilizer and NPK compound fertilizer on available N and P in the soil, fresh weight of caysim (Brassica chinensis L. var. parachinensis.), and their uptake by caisim shoots after grown in low fertility soil. The experimental design was a randomized block design consisting of seven combinations and doses of consortium biofertilizer and compound fertilizer; and three control treatments. All treatments were repeated three times. The results showed that the combination of the which combination treatment of inorganic fertilizer and biofertilizer had a significant effect on the fresh weight of caysim shoots, available P and N and P uptake after harvesting compared to the biofertilizer treatment alone or without fertilization. Several treatments of combined doses of biofertilizers and NPK compound fertilizer produced the same yield as NPK compound fertilizer alone. The application of 300 kg/ha of compound fertilizer combined with 3,75 L/ha of biofertilizer enabled to increase the yield up to 16% compared to NPK fertilizer alone. This experiment explained that inoculation of biofertilizers can reduce the dose of NPK fertilizer to maintain yield, available P residue in soil and P uptake

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

Strawberries in tropical West Java are cultivated intensively in potted soil but the substrate condition received less attention. The objective of this descriptive research was to evaluate the chemical and macronutrient profile in potted-soils for strawberry cultivation, and to determine beneficial microbes’ population in root-free bulk soil and rhizosphere of potted-strawberry.  The soil samples collected from 12-months and one-month-old potted strawberry; both contained Inceptisols soil order with 10 t/ha and 25 t/ha manure respectively. The proximate analysis was performed using Association of Official Analytical Chemists Method. The microbial enumeration was performed by Serial Dilution Plate Method in specific medium. The results showed that potted soils were not saline, but slightly acid, low in organic carbon and high in cation exchange capacity. The soil reactions were suitable for strawberry but the electrical conductivity was too low for strawberry growth. The potted soils have low to very low carbon to nitrogen ratio, but high in total nitrogen and very high in potential P2O5 and K2O. The population of phosphate-solubilizing bacteria, nitrogen-fixing Azotobacter, total bacteria and total fungi in old potted soil were low; but its counts were increased in manure-treated potted soil. The ratios of bulk soil to rhizosphere microbial count were only 1.0-1.25. The study verified that the doses of organic matter should be increased, while decreasing the chemical fertilizer level.

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

Kadar merkuri (Hg) yang tinggi pada tailing tambang emas adalah sumber pencemaran lingkungan termasuk lahan pertanian. Penurunan kadar Hg di tailing dengan metode bioremediasi adalah strategi yang efektif, murah dan mudah. Azotobacter adalah rizobakteri pemfiksasi nitrogen dan penghasil eksopolisakarida yang mengubah mobilitas logam berat serta memicu pertumbuhan tanaman dengan optimal jika terdapat bahan organik. Penelitian ini dilakukan untuk mengevaluasi pengaruh dosis bahan organik dan Azotobacter strain resisten Hg terhadap perubahan kadar Hg di tailing dan tanaman jagung. Percobaan rumah kaca dirancang dalam Rancangan Petak Terbagi dengan tiga ulangan. Petak utama adalah dosis bahan organik yang terdiri atas 22,5; 30 dan 37,5 g/polibeg. Anak petak adalah strain bakteri terdiri atas tanpa inokulan, Azotobacter indigen, A. chroococcum, dan konsorsium kedua bakteri. Hasil penelitian menunjukkan bahwa inokulasi Azotobacter meningkatkan tinggi dan bobot kering tanaman jagung umur 3 minggu. Aplikasi kompos kotoran sapi 30 g/polibeg disertai inokulasi A. chroococcum maupun konsorsium Azotobacter menurunkan kadar Hg tanah dan meningkatkan serapan Hg di tanaman. Penelitian ini menjelaskan bahwa inokulasi Azotobacter menginduksi serapan Hg oleh tanaman sehingga berpotensi digunakan untuk bioremediasi tailing terkontaminasi Hg dengan tanaman fitoakumulator.

Abstract

Illegal artisanal gold mining in Kebunlado, Riau Province has damaged the smallholders estate. The use of mercury for extracting the gold is potentially pollute the soil and syrrounding water as well as threats plantation productivity and it’s food chain. The purpose of this research is to study the mining impact towards the physical and chemical properties of the soil around the plantation, and measure the mercury contamination within the tailings, soil and river to be compared with the soil sample near the mine area. Sampling was carried out in 10 locations to study the properties of the land surrounding the artisanal gold mining. Physical and chemical properties of the soil were studied.The samples came from the mine sites (7 samples) and its surrounding area (3 samples). Sampling was conducted using a toposequence transect method, based on its topographical conditions and soil parent material with the purposive method. Mercury level was measured from eight soil samples that were sampled from surrounding artisanal mine area and six water samples from the surrounding rivers. The research showed that the soil characteristics had changed after mining activities. The soil properties were higher in sand, with bulk density and permeability compared to intact soil. However, there was no distinct change in pH, total nitrogen, organic carbon as well as available P, except C/N in post mine area was relatively low. Mercury content in the gold mine area was higher than that of the average mercury within the soil around the world. The Mercury in the river stream exceeds the threshold based on Indonesia Regulation. The study suggested that land reclamation is needed to develop oil palm plantation in terms of improving the soil physics, increasing C/N and remediation as well as reducing the mercury in soil and water.

Abstract

Urea fertilizers and biofertilizers play an important role in potato (Solanum tuberosum L.) cultivation, but urea fertilizers are volatile and leach out easily that reduce their effectiveness. Urea coated with beneficial bacteria-enriched organic matter is expected to increase nitrogen used efficiency. The purpose of the experiment was to determine the ability of bacterial-coated urea (BCU) included Bacillus and Azotobacter to improve the growth, nutrient status and yields of potatoes grown in field; as well as to reduce urea dose. The experiment was setup in randomized block design with five treatments and six replications. The treatments were four combinations of the dose and formulation of BCU; and conventional urea fertilizer as control treatment. Application of both BCU formulation increased plant height as well as N and P uptake particularly when the recommended dose was used.  In contrast, the doses and formulation of BCU did not affect chlorophyll content. Application of BCU-A or BCU-B at the rate of 200 kg/ha increased tuber weight by 59% and 81% respectively.  Both high and low dose of BCU did not reduce the vegetative growth and yield compared to the plants fertilized with conventional urea. This experiment showed that BCU is considered to reduce the rate of Urea in potatoes cultivation.
