Abstract

This research was conducted to evaluate the yield potential of 19 somaclonal variants resulting from in vitro selection when planted under drought stress condition in the field. Field test was done by planting the variants, the parents, and checked varieties in the field during dry season, and was irrigated once a week for non-stress and once two weeks for drought stress treatment. Split-plot design arranged in a factorial (2 x 28) with three replications was used in this research. Observations were done on yield and yield components. Analysis of variance was used to see the difference between treatments and then it was continued with analysis using Honestly Significant Difference test to find out the best treatments. There was no interaction between genotype and drought stress on seed yield. Different genotypes showed a significant difference on this character. It indicated that the yield potential of selected variants was not affected by drought stress treatment. This research gave 10 variants having the potential to be developed as drought resistant genotypes. However, these ten potential genotypes need to be tested further in field trial to find out the yield adaptability and stability and their resistance to drought stress.   Keywords: somaclonal variants, in vitro selection, drought stress, soybean, selection

Abstract

Low productivity of shallot in Indonesia can be improved through development of high yielding variety. The availability of genetic information related to the character being improved is inevitable for effective breeding program. In this study, seven shallot genotypes were evaluated for their combining ability for yield improvement using half diallel cross.  Heterosis effect and heritability estimate was also investigated for yield-related characters.  The results showed that there were significant differences in general combining ability (GCA) and specific combining ability (SCA) among the evaluated genotypes. Tiron and Timor had the greatest GCA.  The greatest SCA and heterosis value was found in crosses of Kuning/Tiron, Timor/Bima Juna, Tiron/Timor and Kuning/Sibolangit. Heterosis effect varied from low to high. Broad sense heritability estimate for all characters was high, but narrow sense heritability was low for most charaters.  The dominant gene action observed on all yield-related characters suggests that the evaluated genotypes are potential to be used in breeding for high yielding hybrid varieties.   Keywords: GCA, SCA, heterosis, heritability, shallot

Abstract

The productivity of rainfed agriculture land developed on Ultisols is limited by physical and chemical constraints. These problems can be solved and consistently high yields obtained only by the development of comprehensive manage-ment systems. In the 1980s, hedgerow inter-cropping was promoted initially for improving soil fertility and sustainability of crop production on nutrient-depleted soils. However the previous enthusiasm for hedgerow intercropping is unsupported by scientific evidence and its labour demand too high. The question remains, is there a window of opportunity where the biophysical principle of hedgerow intercropping is sound? Research to compare the long-term performance of crops and trees in hedgerow intercropping and monocluture cropping is needed. This research has been conducted at long-term field experiment station at the BMSF-Project, Lampung, Indone-sia. The experiment site had non-nitrogen-fixing peltophorum (PP), nitrogen-fixing gliricidia (GG) and alternate peltophorum and gliricidia (PG) hedgerow intercropping and maize / groundnut monoculture (C) treatments. We concluded that the net interactions related to soil fertility and competition for growth resources in peltophroum were positive for crop yield in PP and PG but negative for GG. Even so, the PP and PG sys-tems resulted in similar yields as monocropping; however, hedgerow intercropping considerably improved soil fertility attributes.

Abstract

This research aims to evaluate the diversity of climbing trees for rattan in agroforestry system. The result of this research is expected to be applied as the standard to improve the management in rattan agroforestry. The research was conducted from June to December 2011 in three different villages: Kalemei, Hiran and Liting in Katingan regency, Central Kalimantan. The data were collected via purposive sampling in two different types of land cover i.e rubber agroforestry (RA) and secondary forest (SF), each of system  had 6 plots and 18 sub-plots of experiment. The evaluation of species diversity was performed by measuring species richness, Importance Value Index, and Diversity Index. Statistic model was constructed by employing the approach in multivariate analysis and cluster analysis. The results indicated that SF had higher species diversity (3.02 – 3.45). The diversity level of RA was higher in Hiran village (3.96), than in the other two villages (<3.0).  Habitat similarity was characterised by the similar composition and structure of vegetation of both SF and RA in Hiran and Kalemei, but not in Liting. The potential of supporting trees for rattan in RA is rather high as shown by high species density and the presence of trees with high wood density (0.75-0.9g cm-3) to extremely high (>0.9g cm-3) as it found in SF.Keywords: Rattan, rubber agroforestry, climbing trees for rattan, secondary forest

Abstract

The research was carried out in Oil Palm Plantation in Ngabang, Landak Distric, West Kalimantan in May 2008. Composite soil samples were taken from the soils, in which the oil palms indicated the nutrient disorders. The aims of the research were to study the soil fertility and nutrient management of Spodosols for oil palm crops. The results indicated that spodic horizons in the oil palm plantation varied between 30 and 70 cm. Besides spodic horizons, the albic horizon, the horizon that cant be penetrated by the crops root, was also found. The texture is sandy with the sand content about 69-98 %. The soil has acidic properties, C organic varied from low to high, low phosphate, potassium, magnesium and Cation Exchange Capacity. In contrast, in the spodic horizon, the content of organic carbon, total nitrogen and CEC were higher, as well exchangeable Aluminum. There was close relationship between soil organic carbon and nitrogen and CEC in the soil. It is advice not to use spodosols for food crop and estate crops. The application of slow release fertilizers combined with organic fertilizers is highly input when oil palm planted on the Spodosol.Keywords: Spodosols, soil characteristic, oil palm

Abstract

Field experiment was conducted in 2005 and 2006 to study response of extra-early maize variety (95TZEE-Y1) to rates of NPK (0, 40:20:20, 80:40:40 and 120:60:60 kg N:P2O5:K2O ha-1) and residual FYM (0, 5, 10 and 15 t ha-1 applied to chilli pepper the previous season) in the semi-arid zone of Nigeria.  Randomized complete block design with three replicates was used.  Higher values for soil physical and chemical properties were obtained in plots supplied with manure the previous season with soil from 2006 experiment more fertile than for the first year, hence produced 21% more grain yield. All the applied NPK rates in 2005 and except 40:20:20 ha1 in 2006 had resulted in early maize crop as compared to control.  Husked and de-husked cob and 100-grain weights and grain yield/ha were higher at 120:60:60 kg NPK ha-1.  Maize grown in plot supplied with 15 t FYM ha1 the previous year matured earlier.  Cobs and 100-grain weights and grain yield were highest in plot supplied with 10 t FYM ha1.  The 10t FYM ha-1 had 69% and 68% more grain yield than the control in 2005 and 2006, respectively.  Highest maize yield was obtained at 120:60:60 kg NPK ha-1 or 10t FYM ha-1.  All the parameters measured significantly and positively related to each other when the two years data were combined.
