<p>Ideal land for growing rubber tree has increasingly limited. Hence farmers and companies were looking for alternative planting of rubber tree in non-conventional areas such as the land of tidal swamps. The study was conducted at Bangun Harjo Village, Air Sugihan Regency, Ogan Komering Ilir (OKI) District, South Sumatera Province, Indonesia from 2005 to 2014. The study was aimed to test the adaptability of six rubber clones in tidal swamps. The design used was a Randomized Block Design with rubber clones as treatment and three replications. Clones planted were IRR 39, IRR 118, IRR 220, PB 260, RRIC 100, dan BPM 24. In each treatment there were 40 rubber trees and 15 rubber trees as samples. The parameters observed were stem girth, bark thickness, and latex yield. The data were statistically analyzed using ANOVA, followed by Duncan Multiple Ranges Test (DMRT) at 5% levels. The results showed that rubber trees in tidal swamps would be able to mature tapping at the age of 60 month after planting (5 years) as long as using the recommended treatment. The growth of stems of each clone at the age of 12-60 month after planting in tidal land have different growth response. However, at the age of 60 BST the highest significant girth growth was IRR 39 (48.66 cm) while the lowest was the BPM 24 (44.17 cm) clone. The average yield per tree per taping (g/t/t) from 1st to 3rd years the highest was IRR 220 (26.23 g/t/t) and the lowest was IRR 39 (15.85 g/t/t). IRR 220 is adapted to tidal swamps.</p><p>Keyword: Adaptability, rubber clones, tidal swamps, growth </p><p> </p><p><strong>Abstrak</strong></p><p>Lahan yang ideal untuk pertumbuhan tanaman karet semakin terbatas sehingga banyak petani dan perusahaan mencari lahan alternatif untuk pengembangan karet di daerah non-konvensional seperti lahan pasang surut.

<p>This research was aimed to identify shade-tolerant soybean genotypes that was suitable for planting under rubber tree plantation. The research was conducted at three locations of rubber tree plantation in Central and East Lampung where the rubber tree were at age of 3 to 4 years, during dry season of 2011. The materials consisted of 30 soybean genotypes, where 23 lines were shadetolerant, and seven were as check varieties (Pangrango, Burangrang, Malabar, Argomulyo, Grobogan, Ijen, and Tanggamus). Each genotype was planted in plot of 4 m x 2.2 m, plant spacing was 40 cm x 15 cm, two plants /hill. The experiment used a randomized block design, repeated four times. Before planting, dolomite of 1.5 t/ha was applied, and 75 kg Urea / ha + 100 SP36 kg/ha + 100 kg KCl /ha was applied at planting time. Observations were done on flowering date, harvesting date, plant height, number of branches, number of reproductive nodes, number of pods, seed weight per plant and grain yield. The light intensity under the rubber tree canopy was observed every week after the soybean age was 30 days (DAP), at 11:00 to 12:00 pm. The levels of shade made by the rubber tree canopy at three locations were different; at Tulangbalak (East Lampung) and Gunungsari (Central Lampung) ranged between 20% to 40%, at Gunungadi (Central Lampung) between 40% to 60%. Genotypes IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 yielded consistently well in two locations, in East Lampung (1.40 t/ha and 1.43 t/ha), in Central Lampung (1.19 t/ha and 1.18 t/ha). Genotype IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 produced the highest average yield out of the three locations, i.e 1.13 t/ha. Genotype IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 were considered as suitable genotypes for planting under the rubber tree of 3 to 4 years of age.</p>

Rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Müell. Arg.] budgrafts of seven clones were evaluated on five contrasting sites in the plateau region of the São Paulo State, Brazil. The objective of this work was to study the phenotypic stability for girth growth. The experimental design was a randomized block design with three replications and seven treatments. Analysis of variance of girth at six-year plant growth indicated a highly significant clone x site interaction. Only linear sites and clone x site components of clone x year interaction were significant, indicating that the performance of clones over sites for this trait could be predicted. The clones GT 1 and PB 235 showed the greatest stability in relation to girth growth, with foreseen responses to change, introduced in the sites. The clones PB 235 and IAN 873 showed significative difference in relation to regression coefficient, representing clones with specific adaptability on favorable and unfavorable sites respectively. The clone GT 1 became the most promissory one in the study of stability and adaptability even showing low girth growth. Expected genetic gains from planting sites, along with estimates of clonal variance and repeatability of clonal means are generally greatest or close to the greatest when selection is done at the same site.

The objective of this work was to assess the genetic parameters and to estimate genetic gains in young rubber tree progenies. The experiments were carried out during three years, in a randomized block design, with six replicates and ten plants per plot, in three representative Hevea crop regions of the state of São Paulo, Brazil. Twenty-two progenies were evaluated, from three to five years old, for rubber yield and annual girth growth. Genetic gain was estimated with the multi-effect index (MEI). Selection by progenies means provided greater estimated genetic gain than selection based on individuals, since heritability values of progeny means were greater than the ones of individual heritability, for both evaluated variables, in all the assessment years. The selection of the three best progenies for rubber yield provided a selection gain of 1.28 g per plant. The genetic gains estimated with MEI using data from early assessments (from 3 to 5-year-old) were generally high for annual girth growth and rubber yield. The high genetic gains for annual girth growth in the first year of assessment indicate that progenies can be selected at the beginning of the breeding program. Population effective size was consistent with the three progenies selected, showing that they were not related and that the population genetic variability is ensured. Early selection with the genetic gains estimated by MEI can be made on rubber tree progenies.

The heritability coefficients and the genetic gains associated with individual, combined and among and within progeny selection, and with multi-effect index selection in long-term rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell.-Arg.] breeding were determined using effective population size (Ne) restriction. Twenty-two half sib progenies were planted at the Jaú Experimental Station, São Paulo State, Brazil, in a complete randomized block design, with five replications and 10 plants per plot. The following traits were assessed when the plants were three years old: number of laticiferous vessel rings (NR), dry rubber production (RP), bark thickness (BT) and stem girth (SG). Significant variability was found among progeny with good chances of obtaining genetic gain for RP, BT and SG. Effective population size restriction caused a greater reduction in genetic gain for RP with combined selection and with the multi-effect index than for individual or among and within progeny selection. The simultaneous use of accuracy values and genetic gain from the lower limits of the confidence intervals for gain indicated that individual selection is to be preferred in Hevea breeding programs.

<p>ABSTRACT</p><p>Effective and efficient fertilization is affected by fertilizer dose, and therefore information on the appropriate dose of a single fertilizer for oil palm will be beneficial to increase the efficiency and effectiveness of fertilization in oil palm plantations. The objectives of this research were to study the response patterns and to determine optimum rate of single fertilizer package related to the growth of one year old oil palm trees. The experiment was conducted from March 2013 to February 2014 at IPB-Cargill Teaching and Research Farm of Oil Palm, Jonggol Bogor. The experiment was arranged in randomized block design with one factor and replicated three times. The treatments were four single fertilizer package as followed: control, 300 g urea + 375 g SP-36 + 350 g KCl + 25 g boric acid + 25 g CuSO4.5H2O, 600 g urea + 750 g SP-36 + 700 g KCl + 25 g boric acid + 25 g CuSO4.5H2O, 900 g urea + 1125 g SP-36 + 1050 g KCl + 25 g boric acid + 25 g CuSO4.5H2O per plant. The result showed that application of single fertilizer package significantly increased the growth of young oil palm linearly as shown by plant height, stem girth, leaf area of frond number 9, chlorophyll and P content of the leaves and quadratically on leaf number at the last observation. The optimum rate of single fertilizer for one year old oil palm trees had not been attained at this research because the plant growth response to fertilization was still linear.</p><p>Keywords: inorganic, leaf frond number 9, optimum rate, growth response, stem girth</p>
