Abstract

Over the function of the upstream region watersheds causes the soil susceptible to degradation of soil fertility. Agroforestry systems that have been implemented should be reviewed to determine their effectiveness in improving soil fertility using a soil quality index. The varieties of soybean that cultivated in the study site were Grobogan, Kaba, and Argomulyo. The variables of this study consists of organic-C, pH, cation exchange capacity (CEC), total-N, available-P, available-K, Na, Ca, Mg, base saturation, and electrical conductivity (EC). Soil quality index calculation performed on selected outcome variables principal component analysis (PCA) which is then multiplied by the weights index on each PC. Selected variables from PCA consist of available-P, available-K, base saturation, and pH. Soil quality index values for all types of Agroforestry in the upstream of Bengawan Solo river basin (Wonogiri) is under secondary forest (<4.1) so that it can be concluded that the adoption of Agroforestry in the upstream of Bengawan Solo river basin has not effect on soil quality based on soil functions in the recycling of nutrients. Mean of soybean grain yield in agroforestry system are higher than the mean of national soybean production, but there are an obstacle such as light conditions.

Abstract

This study aimed to develop the cacao (Theobroma cacao L.) in vitro regeneration system through somatic embryogenesis on kinetin supplemented DKW medium and somaclonal variation assessment using SSR markers.  Callus were initiated from basal petal and staminoid explants cultured on callus induction (CI) medium contained DKW basalt salts and kinetin:2,4-D ratios of  1:15.5, 1:7.8 or 1:3.9 and then transferred onto secondary callus growth (SCG) medium contained WPM basalt salts and kinetin:2,4-D ratios of 1:7.8 or 1:3.9. The calli were then subsequently transferred onto embryo development medium contained DKW basal salts with or without the addition of amino acids, adenine or activated charcoal for the formation of somatic embryos. Nine cacao genotypes were tested for their  ability to develop somatic embryos. Results of this study indicated DKW medium supplemented with Kinetin in combination with 2,4-D effectively induced cacao somatic embryogenesis. The highest somatic embryos formation was abtained from kinetin:2,4-D ratio of 1:3.9 and 1:7.8 in CI and SCG medium respectively. Cacao genotype responses were highly explant type dependent. The developed method resulted in a high percentage of somatic embryo formation (5.6-66.7%), germination (50%)  and plantlet conversion (65%) and a medium percentage of somaclonal variations based on SSRs marker analysis.

Abstract

This research aimed to determine the best land and water management by arrangement of plant spacing, irrigation, and drainage of rubber plantation in order to improve rubber plantation productivity. This research was done using The WaNuLCAS (Water, Nutrient and Light Capture in Agroforestry System) model to determine the best land and water management under several scenario combinations of two factors. The first factor was rubber plant spacing arrangement system, which consisted of three levels, i.e. single row (3 x 7 m), single row (3 x 6 m) and double row (2 x 6 x 14 m). The second factor was water management treatment, which consisted of four levels, i.e. without irrigation and drainage, irrigation in dry season, drainage in wet season, and irrigation and drainage in dry and wet season respectively. The results showed that drainage treatment could enhance rubber plantation productivity. Moreover, rubber plantations which were using single row (3 x 7 m), single row (3 x 6 m) and double row (2 x 6 x 14 m) had no significant difference on latex production per hectare.

Abstract

Flood is general phenomenon found in most areas of Indonesia. This can obstruct rice crop cultivation on lowland swamp areas. Fertilization strategy is one of the efforts to increase rice crop growth and production on flooded condition. The objective of this research was to determine the best fertilization strategy on vegetative stage related to rice crop growth and production under flooded condition at two types of lowland swamp. The experimental design used in this research was split-plot design with three replications. The main plot was fertilization treatment consisting of P1 = base fertilization, P2 = fertilization before flooded, P3 = fertilization after flooded and P4 = fertilization before and after flooded. The subplot was rice variety which consisted of V1 = Inpara 3, V2 = Inpara 5, V3 = IR 64 and V4 = Ciherang.  The results showed that fertilization strategy was capable of increasing rice crop growth and production under flooded condition at two types of lowland swamp.  Rice variety Inpara 5 added with fertilizer before flooded on shallow-backswamp and fertilizer addition before and after flooded on middle-backswamp was the best treatment that had produced rice yield with magnitude of 4.48 and 3.43 ton per hectare, respectively.

Abstract

The behavioral role of male ambrosia beetles, Platypus quercivorus, in subsocial colonies both field and laboratory has been investigated. The entrance tunnels, where the male beetles are staying, are short, with a mean 4 cm long and mostly incline upwards from outside to inside at an angle of around 20º. To examine the role of males, another male or female (as the invader) was placed into a tunnel. When inhabitant males stayed in the tunnel they quickly expelled the invaders, regardless of their sex of the invaders. However, when an inhabitant male was removed an introduced male or female could freely enter the tunnel and was accepted by the inhabitant female. Upon replacing an inhabitant male with an invader male or female and then putting another invader male or female into the tunnel, no rejection occurred, suggesting that invader males and females play no role in guarding the tunnel. Based on the results an inhabitant male seems to have three responsibilities; protection of the gallery from invaders, protection of progeny (larva) from falling down and also keeping the gallery clean from frass. The 20º angle of the entrance tunnel tends to aid both in gallery protection and in frass clearing.

Abstract

Begomovirus infection has a significant impact of lowering chilli yield in Indonesia. A constraint of narrow genetic variability of chilli in Indonesia has made the mutation breeding program as a solution worth-pursuing in increasing the genetic variability. The objective of this study was to determine the LD50 point for each of the five irradiated chilli genotypes and the optimum dose of gamma irradiation in inducing chilli resistance to Begomovirus and other improved agronomical traits. The study was conducted in the Indonesian Vegetable Research Institute (IVEGRI) at Cikole-Lembang, elevation 1,200 m above sea level, from March to December 2013. Split plot design was used with genotype as main factor (Kencana, Lembang-1, SSP, Tanjung 2, Seloka) and irra-diation dosage as sub-factor (0, 200, 400, 600, 800 Gy). All treatments were replicated three times. The results showed that LD50 points of the five irradiated chilli genotypes were in the range of 422.64-629.68 Gy. There were some chilli genotypes in the population of M2 that had high coefficient variance genetic (CVG) and broad sense heritability (h2bs) value for disease incu-bation time. This could be used as resistance parameter to Begomovirus and improvement parameter of several agronomical traits.

Abstract

The adaptation of hybrid rice varieties mostly are in specific location and season, but there are some of the varieties have a wide adaptation then adopted by the farmer in the large area. Replicated yield trials were conducted to study the stability of hybrid rice yield and identify the best location to optimize their yield per ha. We have conducted the trials in three location such as Sukamandi, Salatiga and Malang during two seasons in 2011. We are analyzing data across location and season  using AMMI and Eberhart Russel methods. The AMMI analysis showed that the  IR79156A/PK88 was adaptable to favorable environments but unstable. This hybrid is always performing well and produce the higher yield compare to check variety. Some of other hybrids  were good only in specific location, i.e. IR62829A/BP2280-1E-12-22 and IR58029A/BP2 280-1E-12-22. Those hybrids produced higher yield in Salatiga and Malang, respectively. Seem to AMMI analysis, the result of Eberhart and Russells method also showed that IR79156A/PK81  was the best hybrid with regression slope (b) around 1 with the yield average higher than average of all hybrids. It indicated that this hybrid has a wide adaptation and probably can be cultivated in the wider ecosystem.

Abstract

The objectives of this study were to examine yield performance of promising amphibious red rice lines, and to evaluate their adaptability to six growing environments in Lombok, Indonesia. Ten promising amphibious red rice lines were tested together with their three parents and one national cultivar (Aek Sibundong), during the rainy extended to dry season 2014 (January-June 2014). The ten promising lines were obtained from two population sources, while the three parents were AKBC52, AKBC86, and a local cultivar, i.e. Kala Isi Tolo (KIT). The testing environments were lowland in Mambalan village (West Lombok), medium highland in Mantang village (Central Lombok), and highland in East Sembalun village (East Lombok), and each location consisted of two systems, i.e. flooded and dry (upland) systems. The experiment in each environment was designed according to Randomized Complete Block Design, with three replications and 14 genotypes as the treatments. Adaptation analysis was based on ANOVA using AMMI and Biplot. The results indicated that among the 14 genotypes, G10(F2BC4A52-42) showed the highest yield, with an average of 7.8 t ha-1 dry seeds. There was a significant Genotype x Environment interaction on the dry seed yield. Biplot analysis indicated that G2(F2BC4A52-44) and G8(F2BC4A52-37)

Abstract

Bioremediation of pollutants including heavy metals and xenobiotics is an economic and environmentally friendly process. A novel molyb-denum-reducing bacterium with the ability to utilize the pesticide glyphosate as a carbon source is reported. The characterization works were carried out utilizing bacterial resting cells in a microplate format. The bacterium reduces molybdate to Mo-blue optimally between pH 6.3 and 6.8 and at 34oC. Glucose was the best elec-tron donor for supporting molybdate reduction followed by lactose, maltose, melibiose, raffinose, d-mannitol, d-xylose, l-rhamnose, l-arabinose, dulcitol, myo-inositol and glycerol in descending order. Other requirements include a phosphate concentration at 5.0 mM and a molybdate concentration between 20 and 30 mM. The molybdenum blue exhibited an absorption spec-trum resembling a reduced phospho-molybdate. Molybdenum reduction was inhibited by mercury, silver, cadmium and copper at 2 ppm by 45.5, 26.0, 18.5 and 16.3%, respectively. Biochemical analysis identified the bacterium as Klebsiella oxytoca strain Saw-5. To conclude, the capacity of this bacterium to reduce molybdenum into a less toxic form and to grow on glyphosate is novel and makes the bacterium an important instrument for bioremediation of these pollutants.

Abstract

The problems of soybean cultivation on tidal land are low in soil fertility, aluminum (Al) toxicity and poor availability of macro nutrients. Soil acidity and Al toxicity are often fixed by liming. The research aimed to determine the calculation method of lime requirement and its application method for soybean on tidal land. The research was conducted on tidal land in South Kalimantan, Indonesia. Treatment consisted of two factors and arranged in randomize complete block design, replicated three times. The first factor was the method of lime rate calculation: (1) no liming,(2) liming based on10% of Al saturation, (3) liming based on 20% of Al saturation, (4) liming based on 30% of Al saturation, (5) liming based on 0.5 x exchangeable Al, and (6) liming based on 1 x exchangeable Al. The second factor was the method of application: (1) surface,and (2) mixed within 20 cm soil depth. The results showed that liming by mixing dolomite with soil within 20 cm depth resulted in 8% higher plant height compared to that applied on the soil surface.  The highest yield was obtained when liming at rate equivalent to 10% of Al saturation was mixed with soil within 20 cm depth.
