Publisher : Brawijaya University

An experiment involving the application of organic matters, either fresh or composted, application of bioagent Trichoderma sp. was conducted to suppress basal stem rot caused by S. rolfsii on peanut. The research was conducted at dry land in Amor-Amor North Lombok District with the pump water well system. The experiments were arranged as split plot design with the main plot was pathogen inoculation and non pathogen inoculation. As sub-plot were the addition of organic matters and or addition of bioagent Trichoderma sp. plus two control treatments. Pathogen S. rolfsii applied as fragment mycelia of 1 x 10 6 fragment/ mL with the number of 10 L/plot. Inoculation of the pathogen was conducted when seedlings were about one month old. The bioagent Trichoderma sp. was applied 50 g/plot as powder in the same time of organic matters application (before planting the seeds). The results showed that application of composted organic matters reduced disease incidence 6-10%, while application as fresh organic matters reduced 1-6%. Combination between application of bioagent Trichoderma sp. with fresh and or composted organic matters suppressed disease incidence 8-10% and 8-12% respectively. Application of bioagent alone on planting medium reduced disease incidence 7.5%. Application of composted organic matters with bioagent Trichoderma sp. increased the number of fresh plant biomass 4.93-11.78 kg.

The productivity of private forest land by using agroforestry of Canna edulis Ker aims to achieve food security at the smallholder level. The purpose of this study was to determine the effect of agroforestry cropping patterns on productivity and quality of Canna edulis Ker tuber on private forest land. The study was conducted in dry area of the private forest land who are administrativelyincluding Tenggerraharja Village area, SukamantriSubdistrict, Ciamis District, West Java Province, Indonesia. The planting of Canna edulis Ker was implemented under the 32 months old Manglieta glauca BI stands. The main plots were three pruning intensity of Manglietia glauca BI stands i.e. P0 (0 % ) , P1 (50%), and P2 (75%). The sub plots were three planting spaces of Manglietia glauca BI, i.e. S1 (2m x 2m), S2 (2m x 3 m), and S3 (3m x 3m). The planting of Canna edulis Ker by monoculture technique was conducted as a comparison. The results showed that the interaction of planting space and pruning intensity gave a significant result on height growth, wet weight and dry weight of plant, wet weight and dry weight of Canna edulis Ker tuber. The growth of Canna edulis Ker that ranged from 181.85 cm (P0S1) to 186.30 cm (P1S1) were higher than the monoculture system on Canna edulis Ker (138.20 cm). The wet weight and dry weight of tuber that ranged from 2089.3 g and 1429.99 g (P2J2) to 3695.5 g and 2678.09 g (P1S2), whreas those in the monoculture system on Canna edulis Ker were 2363.1 g and 1528.7 g. However, the protein, fiber and carbohydrate contents of P0S1, P1S1, P2S1 treatments were lower than those of the monoculture system on Canna edulis Ker. The planting pattern of agroforestry were able to improve the plant height of Canna edulis Ker tuber but giving less percentage of carbohydrate and protein of tuber than the monoculture.

Journal of Degraded and Mining Lands Management Vol 1, No 3 (2014)
Publisher : Brawijaya University

Land degradation was exacerbated and its management was challenged by population growth and global climate change. The impacts of land degradation on food security, ecosystem services and biodiversity become a more serious problem particularly in developing countries. Biochar, based on the current research findings, is capable to amend degraded lands. This paper reviewed relevant biocharproperties and identified the opportunities of its using for recovering deteriorated lands.Biochar was traditionally recognized as a good absorbent, energy source, and its ash was used by farmers to recover soil fertility. Recent findings revealed that application of biochar improved soil water retention, enhanced soil aggregation, decreased soil bulk density and increased soil infiltration. It also increased soil cation exchange capacity, soil pH, mineral nutrients, reduced nutrient leaching, support microbial population and activities, and suppressed the pest. The sorption capacity of biochar to soil and water pollutants such as Pb, Cu,Ni, Cr, Cd,dioxine, atrazine, and concurrently eliminatedthe environmental problems such as hypoxia, eutrophication, and algae bloom, have also been investigated. Investigation on its role to mitigate climate change revealed that biochar is capable in reducing greenhouse gasesemissions such as CO2, N2O, and CH4. All those beneficial effects of biochars were attributed to its high porosity, large surface area and surface charge, high carbon, ash and nutrient content, and its stability to be degraded. Thus, biochar could be potential for ameliorating degraded lands.

Publisher : Brawijaya University

Nutrient leaching is often a problem especially in tropical areas with soil fertility constraints. This study aims to reveal the effect of biochars on leaching and uptake of nitrogen and potassium from degraded soils cultivated with maize. Each of three types of biochar originated from rice husk, wood, and coconut shell, was applied to the soil placed in PVC tube at four rates (0,15, 30, and 45 t/ha). Maize was then planted in each pot. All pots received urea (135 kg N/ha), SP 36 (36 kg P2O5/ha), and KCl (110 kg K2O/ha). Twelve treatments (three biochars and four application rates) were arranged in a factorial randomized block design with three replicates. Results of the study showed interaction effects of biochar materials and biochar rates on nitrate leaching (except on day 1 to 30) and potassium, N uptake, and plant growth. On day 1-30, leaching of nitrate and potassium was reduced by biochar application. The lowest nitrate leaching was observed at rate of 45 t /ha of wood biochar, while application of 45 t/ ha coconut shell biochar resulted in the highest K leaching. Beside, wood biochar resulted in a similar nitrate leaching with that of coconut shell biochars, but nitrate leaching increased with increasing rate of biochar chaff on 30-60 HST. All biochar materials yielded a similar potassium leaching at all rates. Application of 45 t /ha biochar husk resulted in the best maize growth.

The main purpose of this study was to elucidate the effects of application of organic wastes and rotation of cropping system on soil fertility status and yields of dry field rice, maize, soybean, groundnut and mungbean in order to overcome soil degradation problems in dry land areas. Six cropping rotation systems (dry field rice-soybean-fallow, dry field rice-groundnut-fallow, dry field rice-mungbean-fallow, maize-soybean-fallow, maize-groundnut-fallow, and maize-mungbean-fallow), and six organic fertilizer rates (0, 5, 10, 15, 20 t/ha, and 25 t/ha) were arranged in a randomized block design with two replicates. The results showed that maize-groundnut-fallow and dry filed rice-groundnut-fallow cropping systems with application of 25 t/ha organic fertilizer were able to increase soil fertility status. At the two cropping systems, status of N-total, P-total, K-total, C-total, CEC, and soil pH were better than other treatments. Soil physical fertility status on maize-groundnut-fallow and dry filed rice-groundnut-fallow cropping systems with application of 25 t/ha organic fertilizer was better than other treatments. Implication of improvement of soil physic characteristic because of this treatment was capable of raising irrigation efficiency about 0.98. Soil biological fertility at the same treatments was also better than other treatments. The average of soil worms was 2.44 per m2 soil. The amount of bacteria was 3.284 x 106 per gram soil. The amount of colony was 545.78 and the average of colony forming holozone was 19.66. Application of 20-25 t/ha organic fertilizer yielded higher crop yields than application of 0, 5, 10, an 15 t/ha organic fertilizer. Maize-groundnut-fallow cropping system and 25 t/ha application of organic fertilizer resulted in the highest propriety index, with value BC-ratio 2.54, BEPproduction 61760, and BEPvalue 982.

Low crop production is acid dryland area of South Sulawesi is due to low availability of P in the soils. One of alternatives that can be performed to overcome the problems of acid soils having high level of exchangeable Al, is through the addition of organic material. In the upland areas in South Sulawesi, crop rice, maize and groundnut crop residues are readily available, but the crop residues are generally only used as animal feed or even burned. This study was aimed to elucidate the effects of groundnut compost on P uptake by maize in Ultisol of Moncongloe, South Sulawesi. Eight kilograms of air dried soil was mixed with compost according to the following treatments; 0, 10, 15, 20, 25, 30, 35 and 40 t compost/ha. All pots received 200 kg/ha KCl and 300 kg Urea/ha as basal fertilizers. Two maize seeds were planted in each pot and thinned to one plant per pot after one week. At harvest maize shoot dry weight and maize root dry weight, length of maize cop, cob weight, cob diameter, weight grains per cob, P uptake by maize, P content in maize grain, soil available P were measured. Results of the study showed that groundnut compost has the ability to improve the availability of P in the soil and increase P uptake by maize grown on an Ultisol of South Sulawesi. Application of 25 t groundnut compost/ha was the optimal rate that can be used to increase P availability in an Ultisol of South Sulawesi.

Publisher : Brawijaya University

Most of P in agricultural soils is in unavailable forms for plant growth. Phosphate solubilizing bacteria can increase soil P availability. This study was aimed to isolate phosphate solubilizing bacteria from sugarcane waste compost and to test ability of the isolated bacterial to dissolve phosphate. The bacteria were isolated from three types of sugarcane waste, i.e. filter cake compost, bagasse compost, and a mixture of filter cake + bagasse + trash biomass compost. The potential colony was further purified by the Pikovskaya method on selective media. Eight isolates of phosphate solubilizing bacteria were obtained from all wasted studied. Amongst them, T-K5 and T-K6 isolates were superior in dissolving P from Ca3(PO4)2 in the media studied. The two isolates were able to solubilize P with solubilizing index of 1.75 and 1.67 for T-K5 and T-K6, respectively. Quantitatively, T-K6 isolate showed the highest P solubilization (0.74 mg / L), followed by T-K5 isolate (0.56 mg / L), while the lowest P solubilization (0.41 mg / L) was observed for T-K4 isolate. The increase of soluble P was not always followed by the decrease in pH.

The aims of this study were to elucidate heritability and the role of drought traits genes of black paddy rice for determination base of the selection method to obtain drought tolerant and high yield potential of black paddy rice. The study was conducted through two experiments during February-November 2013. The first experiment was the establishment of populations from crosses carried out in the hybridization room. The second trial was evaluation of the genetic diversity of drought properties held in the greenhouse of the Faculty of Agriculture, University of Mataram. Planting was carried out in pots without experiment design. Population of P1 (parental-Situ Patenggang), P2 (parental-Baas Selem) were 50 plants of each; population of F1, F1BC.1.2, and F1BC.1.1 were 25 plants of each, and 250 plants of F2, as well as control of drought susceptible variety (IR20) was 10 plants. To determine the heritability and the role of genes controlling drought traits were used index of bud dry and cure of IRRI standard. The results showed that crossing of black paddy rice "Baas Selem x Situ Patenggang” had relatively moderate heritability in broad sense and low heritability in narrow sense. In the crossed F1 population was found that gene action of drought trait was not perfectly dominant

The availability of nutrients, especially N, P, K in the degraded peat are very low. The high organic acids can decrease the soil pH, its causes the negatively charged nutrients such as nitrate and phosphate are also very low. Ameliorant contributes some cations both monovalent and polivalent which acts as a bridge cations, thus increasing the availability of nutrients, especially nitrogen and phosphate. The objective of research was to determine the storage efficiency of N, P, K on application of some ameliorants on degraded peat land. The experiment was conducted at the laboratory of ISARI, Banjarbaru. Peat soil collected from the degraded peat land at Kalampangan, Central Kalimantan. The treatments were 8 ameliorant formula and two control treatments (+NPK and -NPK). The treatments were arranged in CRD, with 3 replications, And using soil coloum (lysimeter). The leaching was conducted every once a week, with 1.25 liter of aquades and the volume of leachate would be recorded. N, P, K concentration in leachate were analyzed periodically at 1, 2, 4, 6, and 8 weeks after incubation. The results showed that the concentrations of N and K on each observation time were relatively same, but P increased significantly at 4 weeks after incubation. The highest concentrations of N, P, and K in leachate were ameliorant from 100% of chicken manure. The storage efficiency of N, P and K varied depending on the type of ameliorant. Ameliorant that improved storage efficiency of N and K was ameliorant which consist of 80% agricultural weed + 20% dolomite, whereas for P efficiency storage was on ameliorant which consist of 80% Chinese water chestnut (Eleocharis dulcis) + 20% dolomite.
