Abstract

An understanding of the structure of the soil food web is critical in determining the practices of soil fertility management based on the biological processes in tropical agricultural regions. The objectives of the study were to assess the variation in trophic level biomass and to analyze the dynamics of the energy channels on the increasing age of cocoa plantation. The characteristics of soil food web structure in smallholder cocoa plantation aged 4, 5, 7, 10, and 16 years were analyzed. The results showed that only biomass at the third trophic level increased with plantation age, but not for the biomass at the lower trophic levels. Biomass in all energy channels did not increased as well along with plantation age. We concluded that variation in the soil food web structure was more influenced by biotic factors of macro-arthropods group, such as facilitation, recolonization capabilities and accessibility in the soil habitat of smallholder cocoa plantation. Keyword: biomass, biotic, energy channel, trophic level.

Abstract

There are many clones grown in Indonesia tea plantations. The latest clones were released around 1990. The new promising clones have been bred through crossing among selected clones in Pagilaran tea plantation. The experiment aimed to select high yield and stable clone. Nine clones were grown in Kayulandak (1300 m asl) and Andongsili (1100 m asl) in Randomized Completely Block Design with three replications. The data of fresh weight per plot in 2007, 2008, 2009, 2011, 2012 were recorded. Eberhart & Russell (1966) and GGE Biplot analysis method was applied for data analyzing. The result showed that all of clones were stable over years in each location except for PGL1 and PGL3 in Andongsili and PGL15 in Kayulandak based on Eberhart & Russell analysis. Significant regression coefficient (1.18) of PGL3 implied that PGL3 was high in yield and responsive. GGE biplot analysis indicated no ideal genotype for each location. PGL10, PGL3, PGL4 and PGL 12 were recommended for Kayulandak, while PGL3 and PGL12 clones were suitable for Andongsili. Both analysis of Eberhart & Russell and GGE biplot showed PGL3 and PGL12 as ideal clone, while PGL10, PGL4, and PGL 15 clone were desireable clones.Keywords : Eberhart and Russell, GGE Biplot, tea clones, yield stability

Abstract

Experiments aimed at examining the effect of aqueous extracts of three weed species on nodulation and nodule function of soybean cv. Melrose have been carried out at the Laboratory of Plant Physiology and Biotechnology, Department of Agronomy and Soil Science, University of New England, Australia. Aqueous extracts of fresh weed material (Amaranthus powellii, Cyperus rotundus and Paspalum dilatatum) at the concentration of 10% (w/v) were added to a minus-nitrogen Hoagland’s nutrient solution in which the soybean plants were grown with 14 hours day length, day and night temperatures of 28 and 20°C, respectively, light intensity of 790 mmol/m2/s, and the relative humidity of 65%. The plants were kept for three weeks prior to the measurement of activity of nitrogenase enzyme and ammonium content of the root nodules. Results demonstrate that all weed extracts reduced the nodulation and nitrogenase activities (ARA) of soybean cv. Melrose. Amaranth was most inhibitory to nitrogenase enzyme activity. However, amaranth extract was less inhibitory than nutgrass extract in total ammonium content.

Abstract

Acid soil area is one of the areas broadly available in Indonesia. However, the complexity of acid soil may lead to low soybean productivity. Hence, soybean variety which is adaptive to acid soil is needed. The objective of this research was to find out expected lines adaptive to acid soil. A number of ten soybean lines and two check varieties were grown in Natar Research Station in dry season II, 2011. This research applied randomized completely block design with four replications. Results showed that 7 of 10 soybean lines had grain yield higher than those of two check varieties. The three lines with the highest grain yield were Tgm/Anj-957, Tgm/Anj-908 and Tgm/Anj-932 with grain yield 1.83, 1.74, and 1.65 t ha-,1 respectively. Tanggamus variety had grain yield higher than Wilis. The highest grain yield line, Tgm/Anj-957, was also supported by the highest number of pods per plant up to 68 pod. Line of Tgm/Anj-995 was the line with the largest seed size, i.e. 16 g per 100 seeds.Keywords: acid soil, expected lines, Glycine max, yield

Abstract

Superior hybrid and CMV tolerant cultivar development requires a pair of high heterobeltiosis parents and both of which are CMV tolerant.  Gene introgression has to be accomplished if the tolerance does not exist in the parents. This research was objected to employ DNA markers and morphological traits on identifying the most resemble BC3 CMV tolerant individuals to their recurrent parents to shortcut the backcrossing cycle. This research used fifteen BC3 populations generated from crosses of hybrid parents PBC1354 and PBC378 with tolerant parents of C1024, C1042 and C1043.  The BC3 populations were previously selected for their CMV tolerance and were characterized by RAPD technique and morphological traits. Selection by means of both RAPD marker and morphological traits identified BC3 individuals 99.9% resemble to their recurrent parent. Genotypes B3A24-20, B3A29-13, B3A29-22, B3B12-13, B3B37-9, B3B12-25, B3C16-5, B3C16-16, B3C34-18 99.9% were similar to PBC378, and  B3D11-8, B3D11-17, B3D38-5, B3E12-17, B3E20-22, B3E31-19  were 99.9% similar to PBC1354.   Those genotypes were both similar to their recurrent parent and tolerance to CMV. The employed strategy shortcut CMV tolerance genes introgression through a backcross breeding.

Abstract

The objective of the study is to examine the effectiveness and feasibility of soil and water conservation techniques. The production of oil palm comprising the fresh fruit bunch, number of bunches, and average of bunch weight were recorded at every harvesting schedule. Tabular data were analyzed by logical comparison among the blocks as a result of application of bund terraces and silt-pit. Financial and sensitivity analysis of the effect of the techniques on FFB production were done. Bund terrace treatment was more effective (4.761 ton or 21.5%) in increasing FFB production than the silt-pit treatment (3.046 ton or 13.4%) when it is compared to that of the control block. The application of bund terraces and silt-pit also presents positive effects i.e. increases the average bunch weight and the number of bunch compared to that of the control. Furthermore, the financial analysis as well as sensitivity analysis shows that the bund terrace application is profitable and feasible (B/C = 3.06, IRR = 47%) while the silt pit treatment is profitable but not feasible.Keywords: Bund terrace, feasibility, production of FFB, silt-pit
