Abstract

Indonesia has been known as soybean importer since domestic production was only 40% of the total demand. Hence, to lower the dependency of soybean import, national production must be enhanced by various means such as improvement of soybean varieties better adapted with local agroclimate conditions. The success of the selection is supported by data of genetic vari-ability, heritability, and genetic progress. Research was conducted at agricultural field station of Faculty of Agriculture, University of Lampung from August to December 2007. Experiment was laid out in a random-ized block design. Plant materials were 13 lines of F4-soybean. Stomatal frequency and leaf greenness were measured at leaves in R4 stage. Results were (1) the character of stomatal frequency showed a widespread genetic and phenotypic variability, high value of heritability, and medium genetic progress. (2) the character of leaf greenness measured with Minolta SPAD-502 showed a narrow genetic variability, widespread phenotypic variability, medium value of heritability, and low genetic progress. (3) the character of seed weight showed a widespread genetic and phenotypic variability, high heritability, and high genetic progress.

Abstract

The research on the effect of planting space treatment on the growth and yield of three accessions of local maize from Maros, Sulawesi Selatan was carried out at the Experimental Garden of Research Center for Biology LIPI, Cibinong on May ? August 2012. The research study was arranged by Factorial in Randomized Completely Block Design with 2 factors and 4 replications, each replication with 10 plant samples. The first factor was accession of pulut local maize (sticky rice maize) with 3 levels factor i.e. Snack Pulut, Rice Pulut and Hybrid Pulut. The second factor was planting space treatment with 3 levels factor i.e. planting space of 100x20 cm, 80x20 cm and 60x20. The treatment of accession was significantly on the vegetative growth of Pulut corn. Accession Rice Pulut growth was the fastest (116.3 cm plant height, 11.5 number of leaves), compared to Snack Pulut (91.2 cm plant height, 7.6 leaves), and accession Hybrid Pulut (111.9 cm height, 8.2 leaves). All of accession showed flowering (70-90 %) at 7 weeks after planting. Accession of Snack Pulut showed fruiting (90%) faster than Hybrid Pulut (80%), and  Rice Pulut (20%). Accession Rice Pulut showed the highest production compared to Snack Pulut and Hybrid Pulut, but has the longest harvest (12 weeks). Accession of Snack Pulut was the fastest harvesting (9 weeks), followed by Hybrid Pulut (10 weeks). The planting space treatments were not significantly different on the growth and production of sticky rice maize, so tight spacing (60x20 cm) may be used to increase yield.  Key words: Planting space, growth, yield, accessions, local maize, Maros

Abstract

Chrysanthemum (Dendranthema grandiflorum) is well known as a commercially valuable flower. However, the plant cultivation has not been well developed. Poliploidization is one of cultivation technique using colchicines as mutagenic agent to produce high quality of flowers. The aims of this research were to study phenotypic characters of chrysanthemum treated by colchicines and to determine the optimum of soaking time to obtain the highly phenotypic characters.Colchicines concentration used in this research was 0.01% with soaking times were 6, 12 and 24 hours. Phenotypic characters observed in this experiment were flower diameter, plant height, stem diameter, long and wide of 5th and 10th leaf from flower base with 10 replications for each characters.The result showed that soaking times treatment with 0.01% colchicines have real influence on flower diameter, plant height, stem diameter, long and wide of 5th and 10th leaf from flower base. The result of colchicines with soaking treatment of 12 hours showed the highly phenotypic characters. In addition, chrysanthemum with colchicines treatment has bigger phenotypic characters than control. Key words: Chrysanthemum, Dendranthema grandiflorum, colchicines, phenotypic characters

Abstract

The objective of this study was to evaluate the effect of pre-germination treatment (physical and chemical) on the percentage and rate of germination of the f1 true seed of cassava derived from female parent UJ 3. The study consisted of two experiment, i.e., Experiment I and II. The pre-germination treatments for the two units experiment were the same, i.e., scarification of seed coat using sand paper, seed coat puncture, submerging the seed in one of the following liquid: the solution of H 2SO4 0,001M for 5 minutes, solution of H2SO4 0,001M for 10 minutes, solution of KNO3 3% for 48 hours, and water for 48 hours. The treatments were also compared to control. After being treated, the seeds were germinated on moistened paper (UKDdp) for Experiment I and on the soil medium in polybag for Experiment II. The two units of experiment were arranged in randomized block design with three replications. Soil medium consisted of mixture of soil and compost (1:1). The results showed that percentage and the rate of germination of the treatment of submerging seed of H2SO4 0,001M for 5 minutes followed by germination on soil medium were high. The percentage and the rate of germination for the treatment were 96%; 10,5% per day respectively; whereas for the control were 78,7% dan 6,8% per day. Scarification using sand paper indicated the percentage and rate of germination were high. It can be concluded that pre-germination treatment by submerging on H2SO4 0,001M for 5 minutes was suitable for germinating true seeds of cassava cv. UJ 3. Key words: Dormancy, pre-germination, Manihot esculenta Crantz, scarification, seed viability

Abstract

Recently, yardlong bean trials were usually conducted in West Jawa. The rainfall of West Java is mostly higher than East Java. Blitar as one of production center of yardlong bean in East Java is estimated to be suitable for conducting the superior advantage test of yardlong beans (Vigna sesquipedalis (L) Fruhw) candidates. The objective of the trial was to test the superior line that has good adaptation in lowland area of yardlong bean production center in East Java with higher yield than control. The trial was conducted at Riawan Tani Station, Blitar, on latosol browness soil type, in Juni ? August 2012, using randomized block design with 8 treatments and 5 replications. The treatments were 5 lines from IVEGRI and 3 lines as control. The lines were:  (1) No. A.3/1630-CSL.19/200 (Pras-1), (2) No. A-8/1630-2489/2000 (Pras-2), (3) No. A-11/2316-2489/2000 (Pras-3), (4) No. A-4/DOA-1215/2000 (Pras-4), (5) DOA (Pras-5), (6) KP1 (releesed variety), (7) The local superior cultivar of Blitar and (8) Superior variety from Riawan Tani Company. The results showed that: (1) The breeding line of Pras 1, Pras 2 and Pras 3 had higher yield than control line (Kp 1, Local Blitar, and Riawan Tani), while Pras 4 and Pras 5 breeding line had similar yield as control; 2) The local Blitar performed the lowest yield and growth; (3) In the general the trial results on the superior advantage test had better yield and growth appearance than Priliminary Yield Test (PYT));  (4) Due to environmental factors,  conclusion of good lines by PYT were not exactly the same with those by the superior advantage test.  Key words : Vigna sesquipedalius lines, the superior advantage test, lowland

Abstract

Shade trees provide ecological benefits such as soil conservation, biodiversity conservation, and providing nutrient through litter fall and nitrogen fixation by legume trees. Therefore, shade tree is a key factor for sustainability coffee production. To evaluate productivity and sustainability of coffee agroecosystems a study was conducted at Sumberjaya Sub-district, West Lampung, Indonesia, during 2007-2010. Farmers were interviewed and two plots of Coffea canephora were set. Plot I was a long term experimental plot, established from shrub to young coffee agro-ecosystems with treatments of open-grown (sun) coffee and Gliricidae sepium, Erythrina indica and Michelia champaca shaded-grown coffee. Plot II was mature coffee fields of 15 years old with the same types of shade trees. The results showed that tipe of coffee agro-ecosystems determined productivity which legume-shaded coffee were higher than nonlegume-shade coffee or sun coffee. Based on the value of Sustainable Yield Index, Benefit Cost Ratio, Net Present Value, and Internal Rate of Return, Gliricidae sepium and Erythrina indica shaded coffee were more visible therefore more sustainable than 2 others coffee agro-ecosystems. Based on the survey and experimental plot, productivity of coffee agro-ecosystems of 3-26 yeras old showed two maximum points resulted in a regression of polinomial model. Key words: coffee, shade tree, productivity, sustainability
