Abstract

Since Inceptisols, in general, contain low soil organic matter and major plant nutrients, inorganic fertilizers are commonly added during corn cultivation. In order to maintain long-term soil health and fertility, bioferilizer and organic ameliorant application are suggested. The addition of nitrogen (N)-fixing bacteria (NFB) can benefit plant growth through the supply of available nitrogen for plant uptake. Organic ameliorants can enhance soil chemical and biological properties. A field trial had been performed to observe the effect of biofertilizer and organic ameliorant on corn growth, N status in soil and plant, and the yield and wasteof corn. The experiment was designed in a Completely Randomized Block Design that consisted of four treatments and six replications. The treatments were 1.2 kg/ha N-fixing mixed biofertilizer, 2 t/ha organic ameliorant, and mixtures of biofertilizer and ameliorant. Control plants received neither biofertilizer nor ameliorant. The experiment results found that N-fixing biofertilizer and ameliorant increased plant height, fully-developed leaves number, soil reaction and N uptake of corn compared to the control. The total-N content was slightly increased after NFB inoculation with and without amelioration over other treatments. Plots treated with biofertilizer and ameliorant produced a higher grain weight compared to the control treatment. Corn wastes such as empty corn cob and husk weight were increased in plants treated with biofertilizer, ameliorant and a combination of both. This study suggested that the combined application of biofertilizer and ameliorant produced 66% more grain yield and 84 % more cob and husk waste compared to untreated plants.

Abstract

Inceptisols umumnya memiliki tingkat kesuburan tanah rendah sampai sedang. Upaya peningkatan ketersediaan hara tanah Inceptisol dengan pupuk anorganik NPK perlu diimbangi dengan aplikasi pupuk hayati dan amelioran organik. Percobaan ini bertujuan untuk mengurangi dosis pupuk NPK dengan menggunakan pupuk hayati dan amelioran organik serta meningkatkan hasil tanaman jagung. Percobaan dilakukan di Pasir Banteng, Kabupaten Sumedang. Penelitian menggunakan RAK faktorial. Pupuk hayati dengan amelioran organik sebagai faktor pertama sebanyak empat taraf: tanpa pupuk hayati dan amelioran (kontrol), diberi pupuk hayati, amelioran organik, dan gabungan keduanya. Faktor kedua yaitu dosis pupuk NPK empat taraf: 100%, 80%, 60%, 40% NPK dosis anjuran.  Dilakukan tiga kali ulangan. Hasil penelitian menunjukkan terdapat interaksi antara pupuk hayati, amelioran organik, dengan pupuk NPK terhadap tinggi tanaman, N-total tanah, bobot tongkol berkelobot dan tanpa kelobot. Pemberian pupuk hayati dan amelioran disertai pupuk NPK 100% dan yang tanpa diberi amelioran menghasilkan bobot tongkol tanpa kelobot sebesar 1.089 g dan 1.064 g per tanaman. Pemberian pupuk hayati dengan amelioran dan pemberian pupuk NPK 100% menghasilkan bobot pipilan per tanaman 526,08 g dan 539,08 g. Aplikasi pupuk hayati dan amelioran organik belum mampu mengurangi dosis penggunaan pupuk NPK pada Inceptisols asal Pasir Banteng. Inceptisols generally have low to moderate soil fertility. The effort to increase the nutrients availability in Inceptisol through the application of NPK fertilizers need to be balanced with biofertilizers and organic ameliorants. This experiment aimed to reduce the dose of NPK fertilizer by using biofertilizers and organic ameliorants and to increase maizeyields. The experiment was conducted in Pasir Banteng, Sumedang Regency. The factorial RBD was used. The biofertilizer with organic ameliorant as the first factor: no biofertilizer and no ameliorant (control), biofertilizer, organic ameliorant, and combination of both. The second factor was dose of NPK fertilizer: 100%, 80%, 60%, 40% of recommended NPK dose. It was repeated three times. The results showed that there was interaction between biofertilizer, organic ameliorants, with NPK fertilizers on plant height, N-total soil, weight of cobs with and without husk. The application of biofertilizer and ameliorant with 100% NPK fertilizer and without ameliorant were 1,089 g and 1,064 g of cobs without husks, respectively. The application of biofertilizer with ameliorant and 100% NPK fertilizer had a grain weight of 526.08 g and 539.08 g, respectively. The application of biofertilizers and organic ameliorants has not been able to reduce the dose of NPK fertilizer on Inceptisols from Pasir Banteng.

Abstract

Low nitrogen content in soil is usually overcome by chemical fertilization. After long application period, high-dose and intensive use of N fertilizers can cause ammonia volatilization and nitrates accumulation in soil. In sustainable agriculture, the use of bacterial inoculant integrated with nutrient management system has a role in soil health and productivity. Azotobacter-based biofertilizer is suggested as a chemical nitrogen fertilizer substitute or addition in crop production to improve available nutrients in the soil, provide some metabolites during plant growth, and minimize fertilizer doses. The objective of this literature reviewed paper is to discuss the role of Azotobacter in agriculture; and the prospective of Azotobacter to increase yield and substitute the chemical fertilizer in food crops production. The results revealed that mechanisms by Azotobacter in plant growth enhancement are as biofertilizer, biostimulant, and bioprotectant. Nitrogen fixation by Azotobacter is the mechanism to provide available nitrogen for uptake by roots. Azotobacter stimulates plant growth through phytohormones synthesis; indole acetic acid, cytokinins, and gibberellins are detected in the liquid culture of Azotobacter. An indirect effect of Azotobacter is exopolysaccharide production and plant protection. Inoculation of Azotobacter in the field integrated with organic matter and reduced chemical fertilizer are reported to improve plant growth and yield.

Abstract

The concept of balanced fertilization application is appropriate for tomato plant cultivation. However, most farmers still apply inorganic fertilizers excessively, which negatively impacts the environment and plant productivity. Alternative efforts can be made to reduce the usage for inorganic fertilizers through effective plant growth-promoting rhizobacteria (PGPR) application. This research studied the characteristics of the PGPR inoculants effectiveness (Azotobacter sp. and Pseudomonassp.) combined with NPK towards tomato in Lembang Andisol. The experimental design used was randomized block design, with three replications: A (Control), B (1 PGPR + 0 NPK), C (1 PGPR + NPK), D (1 PGPR + NPK), E (1 PGPR + NPK), F (1 PGPR + 1 NPK), G (1 PGPR + 1 NPK), H (2 PGPR + 1 NPK), I (0 PGPR + 1 NPK), J (½ PGPR +1 NPK). The results showed the treatments of C, F, and J resulted in higher total soil N content than the control treatment. Meanwhile, C and D treatment increased plant N uptake compared to control. Nitrogen uptake increased with the decrease of NPK dose application. All of the PGPR inoculation treatments with NPK combination did not increase Azotobacter sp. population and tomato yield. The yield of tomatoes per hectare showed that the PGPR inoculation at a dose of 3 l/ha (1 PGPR + NPK) increased yield by 28.7% compared to 1 NPK (150 kg/ha of Urea, 100 kg SP-36 and 50 kg/ha KCl) dose. Application of 3 l/ha of PGPR inoculant can save up to 75% of NPK usage

Abstract

Indonesia is one of the largest coconut (Coconus nucifera L.) producing country in the world. Cocopeat can be mixed with chicken manure because of its relatively higher nutrient content compared to other manures. Cocopeat and chicken manure mixture can be an alternative to soilless planting media to support sustainable agriculture. In this study, the chemical and biological characters of cocopeat and chicken manure mixture were analyzed. Five different of combinations of cocopeat and chicken manure mixture: A (1: 1), B (2: 1), C (1: 2), D (2: 3), E (3: 2) were used as treatment. A Completely Randomize Design (CRD) with two replications were used. Data were analyzed with Independent T-test methods. The lowest C/N (33,39) was from D treatment (2:3), highest P2O5 content (0,08%) by C treatment (2:1), highest K2O content (0,03%) from A treatment (1:1) as control, the highest Ca-dd content (31,3%) was E treatment (3:2), and the highest Mg-dd content (1,45%) was obtained from control. All treatments reached the minimum moisture content limit for planting media. The total number of highest bacteria (161 x 107 cfu/g) is showed by D treatment (2:3), and the highest fungi level (58 x104 cfu/g) shown by C treatment (2:1).

Abstract

The aim of this research is to find the characteristics of three PGPR isolates—Azospirillum sp., Bacillus sp., and Pseudomonas sp.: First, by profiling their characteristics in a liquid bioremediation system and secondly by measuring their performance as a bioagent in a soil phytoremediation system using ramie plant (Boehmia niviea L.). A Randomized Block Design in triplicate is used: (1) a Nitrogenfree medium with mineral media containing 1% (wt/v) petroleum hydrocarbons; and (2) 1% (wt/v) glucose medium as control. We tested their petroleum-degrading capacity, nitrogenase activity, phytohormones production, and ramie plant growth. The results showed that both Pseudomonas sp. (98.7%, 81.78% degradation efficiency) and Azospirillum sp. (93.80%, 83.70%) were the superior candidate in both systems. They both show reduced but adequate phytohormone production, managing to improve ramie plant growth. Both also showed reduced but sufficient nitrogen fixing capabilities to improve hydrocarbon degradation activity effectively. Meanwhile, Bacillus sp. has the lowest biodegradation capabilities (84.07%; 78.6%) and lowest nitrogenase activity, while failing to improve plant growth. Therefore Bacillus sp. would be more beneficial in a bacterial consortium where its characteristics (high IAA production) can be coupled with other isolates that can offset its lack of phytohormone or nitrogenase activity.

Abstract

 Interaksi sinergis antara tanaman-bakteri dapat digunakan untuk meningkatkan kinerja fitoremediasi tanah yang terkontaminasi hidrokarbon (HC). Penelitian bertujuan untuk karakterisasi plant growth promoting rhizobacteria: Azotobacter sp. dan Pseudomonas sp. dalam kinerja fitoremediasi limbah minyak bumi menggunakan tanaman sorgum (Sorghum bicolor L.). Penelitian menggunakan rancangan acak kelompok faktorial (RAK-Faktorial) terdiri dari inokulasi Azotobacter sp. sebanyak 0%, 1%, 2%, dan 3% per konsentrasi total petroleum hydrocarbon (TPH), dan inokulasi Pseudomonas sp  0%, 1%, 2%, dan 3% per TPH. Hasil penelitian menunjukkan bahwa tidak ada interaksi antara inokulasi Azotobacter sp. dan Pseudomonas sp. terhadap seluruh variabel respon. Namun, efek mandiri terlihat pada efisiensi biodegradasi HC, yaitu inokulasi Azotobacter sp dosis 3% berbeda secara signifikan dengan kontrol pada fase ke 4 minggu setelah tanam (MST), tetapi tidak signifikan pada fase 14 MST. Inokulasi Pseudomonas sp. tidak memberikan efek yang signifikan antar perlakuan terhadap efisiensi biodegradasi HC pada dua periode pengamatan. Populasi Azotobacter sp. dan Pseudomonas sp. menurun pada periode 4 MST, selanjutnya meningkat  pada periode 14 MST. Pertumbuhan tanaman sorgum mengalami retardasi selama 14 MST. Residu hidrokarbon terakumulasi lebih tinggi di bagian akar daripada di bagian tajuk tanaman. Azotobacter sp. dan Pseudomonas sp. berperan sebagai binding agent yang dapat menghambat serapan hidrokarbon oleh akar sorgum.ABSTRACTThe synergism interaction between plant-bacteria can be used to improve performance of phytoremediation hydrocarbon (HC) contaminated soil. The study aimed to characterize  Azotobacter sp. and Pseudomonas sp. in petroleum phytoremediation performance using sorghum (Sorghum bicolor L). The research used a randomized block design with two factors: Azotobactersp. inoculation 0%, 1%, 2% and 3% per total petroleum hydrocarbon (TPH) concetration, and Pseudomonas sp inoculation:  0%, 1%, 2% and 3% per TPH concentration. The results showed there was no interaction between Azotobacter sp. and Pseudomonas sp. inoculation to each response variable. The independent effect of 3% Azotobacter sp. to biodegradation HC efficiency was significantly different from the control at phase 4 weeks after planting (WAP), but not significantly different at phase 14 WAP. Pseudomonas sp. effect did not show a significantly different between treatments on the hydrocarbon biodegradation efficiency in the two observation periods. Azotobacter sp. and Pseudomonas sp. population decreased at period 4 WAP, then increased at period 14 WAP. The Sorghum growth was retarded during 14 WAP. Hydrocarbon residues accumulated higher in the roots than in shoot. Azotobacter sp. and Pseudomonas sp. act as a binding agent that can inhibit the hydrocarbons uptake by sorghum roots.

Abstract

Pyrolysis gas chromatography-mass spectrometry (Py-GCMS) is a simple, rapid, and reliable analytical technique to assay lignocellulose biomass. This study aims to analyze the chemical content of various ages of platinum fast-grown teak wood using PyGCMS coupled with interdependence multivariate analysis. Fifty-eight peaks were shown in the pyrogram originating from carbohydrates, lignin, and extractive derivatives. Along with age, platinum fast-grown teak wood showed higher carbohydrate derivatives in heartwood than sapwood. Compared to teak wood grown in conventional (between 36.72-45.69%), platinum fast-grown teak wood has a higher content of carbohydrates (42.82-48.04%). A substantial amount of G-unit lignin was detected in the sapwood, while the S-unit lignin dominated the heartwood. The extractive content of 10-years-old teak wood heartwood was 4.82%, higher than 10- and 20-years-old heartwood from conventional wood (2.23% and 8.88%, respectively). Multivariate analysis of the chemical compound showed that Py-GCMS could be utilized to classify platinum fast-grown and conventional teak wood. 2-methyl anthraquinone (MAQ) content of 10-year-old fast-grown teak wood was 2.5 times higher than 20-year-old conventional teak wood. Based on the study, platinum fast-grown teak wood is promising as alternative wood material to fulfill the market demand for conventional teak wood.
