Publisher : Brawijaya University

The application of ameliorant has been suggested to improve soil fertility and crop growth in post illegal gold mining (PIGM) lands. This study evaluated the effect of ameliorant types and semi-permeable layer on properties of soil in PIGM lands and growth of sorghum. A field experiment employed two treatments, i.e. type of ameliorant and semi-permeable layer. There were four ameliorant types applied i.e., without ameliorant (M0); coastal sediment at a dose of 40 t/ha (M1); biochar at a dose of 4 t/ha (M2), and coastal sediment at a dose of 30 t/ha + 4 t biochar/ha(M3). The second treatment consisted of two levels, namely: without a semi-permeable layer (S0) and the semi-permeable layer of 20 cm depth from the soil surface (S1). The results showed that types of ameliorant gave different effect to soil properties. Application of coastal sediment at a dose of 40 t/ha significantly increased the contents of Ca and Mg, whereas application of biochar at a doses of 4 t/ha increased soil CEC. The semi-permeable layer did not significantly affect plant height and stem diameter of sorghum. The highest of sorghum growth was reached by application of coastal sediment at a dose of 30 t/h + biochar at a dose of 4 t/ha. The combination of coastal sediment and biochar from banana peels could complement each other to improve soil fertility in PIGM land

Productivity of agricultural land in coastal area is limited by salinity. Planting tolerant variety combined with amelioration is an effective management to increase productivity of salt affected land. The objective of this study was to identify effective ameliorant for improving growth and yield of groundnut on saline soil. The trial was conducted on saline soil in Tuban from May to September 2015. The trial consisted of two factors that were arranged in a completely randomized block design, three replications. The first factor was two groundnut varieties (Domba and Hypoma 1). The second factor was six soil ameliorations (control, 120 kg/ha K2O, 2.5 t/ha dolomite, 2,5 t/ha of gypsum, 2.5 t/ha of manure, and 1.5 t/ha of gypsum + 2.5 t/ha of manure). Results showed that Domba and Hypoma 1 varieties could tolerate and completed their life cycle at insitu saline condition. Hypoma 1 was more prospective to be developed in saline condition associated with higher survival as well as better pod setting and seed development than Domba. Combination of gypsum and manure provided better effect than other treatments in improving saline soil, since it reduced exchangeable Na, Na saturation, and EC of soil, and also improved groundnut yield.

Publisher : Brawijaya University

Climate variability is the fluctuation of climatic elements from the normal or baseline values. Agrarian communities are the most sensitive social groups to climate variability and associate extreme weather-induced hazards due to the fact that climate variability affects the two most important direct agricultural production inputs, such as rainfall and temperature. As Ethiopia is heavily dependent on agriculture its economic development is being hindered by climate variability coupled with many other deriving forces. Therefore, the objective of this study is to examine climate variability, local communities’ perceptions and land management strategies to reduce the adverse impact of climate variability in Lay Gayint Woreda, Ethiopia. Both primary and secondary data were used to complete this study. Primary data were collected and analyzed from a total of 200 randomly selected respondents reside in different agro-ecological areas. Metrology data were gathered from Nefas Mewcha Station from the years 1979 to 2010. Standardized rainfall anomaly index (SRAI), crop diversification index (CDI) and other descriptive statistical techniques were used to analyze the data. The results obtained from the climate data revealed an increase in temperature, and decrease and/or erratic in rainfall distribution. Time series SRAI from 1979 to 2010 indicates that 2002 and 2008 were characterized by extreme and severe dry conditions in order of importance with high impact on crop yields whist only 1984 and 1990 received near normal rainfall amount. Similarly, the survey result reveals that out of the total household heads, 87.5 % perceived that there was an increase in temperature over the last 20 years. The survey result also disclosed that significant numbers of households are more likely to adopt different land management strategies to reduce the negative impact of climate variability. Constructing terraces and check dams as well as planting trees were the major land management strategies used by the local communities. However, crop diversification index (CDI) was found to be 0.11 as the cultivated area is stanch to one crop indicating very low alternative crop production in the study area. Although the study area receives variable and inefficient rainfall the rugged topography and poor soil conditions have hindered the development of irrigation facilities. Local context-specific integrated watershed management activities, small-scale irrigation schemes and extension services need to be strengthened to reduce the impact of climate variability. Policy makers need also to substantially invest in establishing information dissemination systems in order to provide reliable weather information for farmers given that crop production is largely dependent on it.

Coal mine overburden (OB) materials were nutrient-poor, loosely adhered particles of shale, stones, boulders, and cobbles, also contained elevated concentration of trace metals. This condition cause OB substrate did not support plants growth. However, there were certain species that able to grow on overburden dumping site. This investigation sought to identify plants species that presence on coal mine overburden. The research was conducted on opencast coal mine OB dumping site in Satui, South Kalimantan. Vegetation sampling was carried out on six different ages of coal mine OB dumps (7, 10, 11, 42, 59 and 64 month) using line transect. Species identification used information from local people, AMDAL report of PT Arutmin Indonesia-Satui mine project, and website. There were 123 plant species, consisted of 79 herbs (Cyperaceae, Poaceae and Asteraceae), 10 lianes, bryophyte, 9 ferns, 10 shrubs, and 14 trees. A number of Poaceae, i.e., Paspalumconjugatum, Paspalumdilatatum, and Echinochloacolona generally present among the stones, boulders, and cobbles. While Cyperaceae such as Fimbristylis miliaceae, Cyperus javanicus, Rhyncospora corymbosa and Scleria sumatrensis most often foundinand around thebasin/pond with its smooth and humid substrate characteristics. Certain species of shrubs and trees present on the 7 month OB dumping site. They wereChromolaena odorata, Clibadium surinamense, Melastoma malabathricum, Trema micrantha, and Solanum torvum (Shrubs), Ochroma pyramidale and Homalanthus populifolius (trees). This plant species could be used for accelerating primary succession purpose on coal mine overburden dumping site. Nevertheless, species selection was needed to avoid planting invasive species.

A pot experiment in green house was done to study the effect of the dosage and speciesof perennial legume green manures to the physiological traits, growth and yield of organic lowland rice (Oryza sativaL.), and to obtain the optimal dosage as well. The research was arranged in a factorial randomized block design consistedof two factors with three replications.The first factor was the species of perennial legume thatconsisted of threespecies: Turi (Sesbaniagrandiflora), Glirisidia (Gliricidiasepium), and Lamtoro (Leucaenaleucocephala) and cow manure as control treatment. The second factor was the dosage of green manure thatconsisted of four levels: 5, 10, 20 and 40 t/ha. The results showed that application ofperennial legumesinto the soil significantly improved the growth and yield of rice. The application of 20 t Glirisidia leaves/haproduced the highest grain yield, followed by 20 t Lamtoro leaves/ha and 20 t Turi leaves/ha. The optimal dosages of S. grandiflora, G. sepium and L. leucochepala leaves that could yield 58.03 g/hill (equivalent to14.51 t/ha), 53.67 g/hill (equivalent to 13.42 t/ha), and 49.67 g/hill (equivalent to 12.42 t/ha) were 28.05, 25.46 and 26.41 t/ha, respectively.

Publisher : Brawijaya University

This study aimed to examine the effect of bacteria found in the rhizosphere of rubber plants in producing exopolysaccharides to improve aggregate stability of sandy soils. Samples of soil have been taken in rhizosphere of rubber plants in West Kalimantan. Serial soil samples were diluted and cultured on ATCC no.14 medium to select potential bacteria to produce exopolysaccharides. Forty-five isolates of exopolysaccharide-producing bacteria isolated from the rhizosphere of rubber plants was inoculated on ATCC no.14 medium. Based on the observations of morphological colony of these isolates, most of them had similarities in colour and shape so that only ten different isolates were obtained based on the morphological colony. Ten isolates were re-grown on MacConcey medium. Three isolates formed thick or slimy mucus when cultured on MacConcey medium. Three isolates grown on the medium of ATCC 14 resulted in dry weight of exopolysaccharide (mg/mL) varying from 0.28 to 7.59 mg/mL with sucrose and glucose as carbon sources. The results of the molecular identification of the three isolates of Klebsiella sp. LW-13, Klebsiella pneumoniae strain DSM 30104 and Burkholderia anthina strain MYSP113 showed that Klebsiella sp. LW-13 and Burkholderia anthina strain MYSP113 with 2% organic matter increased soil aggregate stability from highly unstable (30.67%) to unstable (45.01-48.20%). This aligned with the results by scanning electron microscopy (SEM) on treated soil and without bacteria treatments.

Heavy metal pollution in agricultural land threatens soil and food quality. Soil pollution could be remediate using biochar, but the effectiveness of biochar on soil quality improvement is determined by types of feedstock and pyrolysis temperature. This study was aimed to explore the effect of different types of biochar on soil properties. Biochar from rice husk and tobacco waste was applied to soil contaminated with lead and mercury. This study was conducted at Sumber Brantas, Malang East Java, and used a completely randomized design with three replicates. Heavy metals content was measured using AAS. The results of measurements were analyzed using analysis of variance at 5% and 1% significance levels. The initial analysis of the soil properties at the research site showed that the soil nutrient status was low, i.e. N (0.2 %), K (0.50 cmol+/kg), and CEC (5.9 me/100g) respectively, but soil pH was neutral (6.8). The research site also has crossed the threshold of heavy metal content for Hg (0.5 ppm), Pb (25.22 ppm), Cd (1.96 ppm), and As (0.78 ppm). Biochar added had a positive influence on soil characteristics improvement. It could increase the content of organic C, i.e. 35.12% and 31.81% and CEC (cation exchange capacity), i.e.30.56 me/100g and 28.13 me/100 g for rice husk biochar and tobacco waste biochar, respectively. However, N, P, and K contents were low i.e. N ( 0.33 and 0.30 %); P2O5 (148.79 and 152 ppm); K (1.58 and 2.11 mg/100g) for rice husk biochar and tobacco waste biochar, respectively.

Fusarium wilt caused by F. oxysporum f.sp. cubense is one of very damaging banana plant diseases which can cause plant death. Disease control using intensive chemical fungicides will have negative impacts on the environment and humans. Endophytic Trichoderma is one of the biological control agents which can reduce the amount of inoculum of pathogens, so it can reduce disease intensity. The objectives of this study was to assess the ability of endophytic Trichoderma in inducing plant resistance against fusarium wilt. Endophytic Trichoderma was obtained from healthy roots of banana from three regencies in Yogyakarta, namely Trichoderma harzianum.swn-1, T. harzianum.swn-2, T. harzianum.psr-1, T. asperrellum, T. gamsii, and T. koningiopsis. Research on induced resintance was conducted in the greenhouse with polybag using Completely Randomized Design with 14 treatments and 3 replications. The results showed that the ability of Trichoderma gamsii antagonism against F. oxysporum f.sp. cubense was 60.61%. T. asperellum and T. harzianum.swn-2 could suppress this disease resulted in disease intensity of 8.33% which categorize as resistant. Trichoderma harzianum.psr-1 was significantly different in stimulating plant vegetative growth. Induced resistance by using endophytic Trichoderma spp. against F. oxysporum f.sp. cubense showed increase in total phenolic compounds on the third and fourth weeks as well as peroxidase activity on the third, fourth and fifth weeks. Observation of lignification on the fifth week showed that lignification occurred in root xylem

A study that was aimed to determine the influence of long of land use and cropping systems on soil fertility and yield of cassava conducted at centre of cassava in Sukadana Subdistrict, East Lampung. Survey was conducted to characterize soil fertility due to the long of landuse and cassava cropping system from February to September 2014. Treatments of cropping system and long of land use observed involving: (1) Cassava monoculture for more than 30 years, (2) Cassava monoculture for 10- 30 years, (3) Cassava monoculture for less than 10 years, (4) Intercropping cassava and maize, (5) Intercropping cassava and groundnut, (6) Crop rotation of cassava and maize, and (7) Crop rotation of cassava and groundnut. The results showed that concentration of all macro nutrients of cassava monoculture for more than 30 years was lower than cassava monoculture for less than 10 years including the decrease of 11% of soil pH, 49% of total N , 66% of organic C, 57% of available P, 64% of K, 70% of Ca, 55% of Mg and 37% of CEC. Intercropping or crop rotation of cassava with legume or non-legume increased the soil pH, organic C, total N, K, Ca and Mg and decreased exchangeable Al. The changes in soil chemical and physical properties due to different cropping system affected the yield of cassava. The highest yield of cassava was obtained by crop rotation of cassava and maize, while the lowest was monoculture for more than 30 years. Cassava monoculture grown for 10-30 years or more than 30 years had low soil fertility so that the yield of cassava was also low. The yield of cassava in the rotation system was higher than the intercropping
