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.

Genetic engineering is an alternative technology that can be used to assist breeders for improving the genetic potential of crop variety. Drought tolerant of rice was attempted by applying genetic engineering techniques by introducing gene OsDREB1A using Agrobacterium tumefaciens. The experiment was conducted in 2008-2010 at the laboratory and greenhouse of the Indonesian Center for Agriculture Biotechnology and Genetic Resources and Development, Bogor, using the transformation method. Callus derived from seeds of rice varieties Nipponbare was transformed by inserting the gene OsDREB1A, then regenerated and acclimatized to generate putative transgenic rice plants. The transformation of calli derived from 469 rice seeds of variety Nipponbare produced 103 putative transgenic rice plants. Plant heights of the putative transgenic plants obtained were generally lower than the control plants (88 cm). The numbers of rice panicles of the putative transgenic plants were generally less than the control plants (9 panicle). Production of filled grain of the putative transgenic plants were less than the control plants; three plants did not even produce seeds, namely B14(2)4.1a, D5.1, and D18. The results of the PCR analysis showed that all the putative transgenic rice plants were confirmed to carry the gene OsDREB1A.

The aim of this study was to obtain information on plant growth rates involving leaves, stem, pods, and seeds, to be used as selection criteria in breeding program, to develop early-maturing soybean cultivar with higher yield than Grobogan variety. The experiment was carried out at ILETRIâ€™s experiment station in Ngawi, East Java during dry season I. Seeds of five soybean genotypes including Grobogan variety were planted on 24 June 2010. Growth rates of leaves, stem, pods and seed were analyzed using linear and quadratic equations. Results showed that Grobogan variety yielded the highest of 2.9 t/ha. There were no genotypes having earlier leaves growth rate (source strength) higher than that of Grobogan variety. The G2 genotype (Sinabung/Argomulyo 415-2) had higher assimilate partition rate to the seed (sink strength) compared to that of Grobogan variety, namely 0.386 g/plant/day and 0,288 g/plant/day, respectively. To improve yield potential through sink strength, a cross of G2 (Sinabung/Argomulyo) and Grobogan is suggested.

The alternating dry and flooded bedding system (Surjan) optimizes land availability, by integrating food crop culture in the lower bed and annual crops in the upper bed position, of the rainfed rice field. Rainfed rice productivity is generally low, to increase its productivity rice culture should integrate the management of crop, water and nutrients. Rice field is regarded as greenhouse gas sources, especially methane (CH4) and carbon dioxide (CO2). Field experiment was conducted in the rainfed rice field in Pati, Central Java, to determine GHGs emission and grain yield from three rice varieties, applied with cattle manure, planted in the rainfed rice field, using alternating beds system. The experiment was arranged in a randomized block design with three replicates and six treatments of the combination of cattle manure application and rice varieties. The rates of cattle manure were 5 and 30 t/ha, while rice varieties were Inpari 1, Inpari 6, Ciherang. Data observed included grain yield, soil pH, fluxes of CO2 and CH4. Combination of Inpari 6 with 5 t/ha cattle manure emitted GHGs higher than combination of Inpari 6 with 30 t/ha cattle manure, while GHGs emission from combination of Ciherang with 5 t/ha cattle manure was lower than combination of Ciherang with 30 t/ha cattle manure. Variety Inpari 1 emitted the lowest GHGs, both from the combination of 5 t/ha and of 30 t/ha. The average grain yield of Inpari 1, Inpari 6, and Ciherang in the rainfed lowland rice each was 6.27, 6.01, and 5.70 t/ha, respectively. The GHGs releases from the rice variety roots depend on the availability of organic matter in the soil that is used as energy source for GHGs forming microbes.

Drought, acidity, and P deficiency are problem in rice production in Ultisol soil in Indonesia. Pup1 locus in rice plant, besides has a role in uptaking P nutrient, was suspected to improve resistant to biotic and abiotic stresses, including drought. BC2F6 lines derived from Situ Bagendit cross containing Pup1 locus had been developed through Marker-assisted Backcrossing method, and had been tested for P fertilizers and resistance to blast. This research was aimed to evaluate the effect of Pup1 locus to drought stress condition. The study was divided into two experiments, namely test of polyethylene glycol (PEG) 8000 and test of root penetration ability test (DTA). The experiment was conducted at the Greenhouse of Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development, from November 2012 until May 2013. The number of lines used in this study was 52 lines, consisted of 24 lines of BC2F6 Situ Bagendit Ã— Kasalath (= SK), 22 lines of Situ Bagendit Ã— NIL-C433 (= SN), three parents namely Situ Bagendit (recurrent parent), Kasalath, and NIL-C433, two tolerant controls for drought namely Cabacu and Gajah Mungkur, and one sensitive control for drought IR20. The research used a completely randomized design for test PEG 8000 and a split-split plot design for test of root penetration ability.Â Results showed that maximum PEG 800 concentrations for drought stress study on rice was 20%. Pup1 locus was more tolerant to drought stress in PEG 8000 experiment through its longer roots and plumules. Pup1 locus gave a positive effect on root penetration ability, with longer roots and more penetrating wax layer. Pup1 locus also showed tolerant to drought on Ultisols soil, as indicated by an increasing dry weight of root and shoot than those of parent without Pup1 locus.

The possibility of sustainable use of sweet sorghum as raw material for animal feed and bioethanol need to be supported by evaluation and selection of sweet sorghum genotypes for high biomass production, sugar content of the stalk, and its ratooning ability. An experiment was conducted at the experimental field of the Cereal Crops Research Institute, Maros, during the anomalic season (La Nina) from November 2009 to September 2010. Fourteen genotypes of sweet sorghum were planted in plots arranged in a randomized block design with three replications. The sorghum seeds were planted as primary crop plants in November 2009 and harvested in February 2010. Ratoons of the primary crop (Ratoon I) started to grow in February 2010 and was harvested in May 2010, while Ratoon II started to grow in May 2010 and was harvested in August 2010. The results showed that none of the sorghum genotypes had the potential of high fresh biomass production, high ratooning ability, and high sugar content of stalk juice. Genotype 15021A produced the highest fresh biomass (63.4 t/ha), but had low ratooning ability l (33-44%) and low sugar stalk juice content (9 brix). Meanwhile, genotype 15105B had high ratooning ability (64-88%) and high sugar content of stalk juice (13 brix), but it had a low fresh biomass production (41.8 t/ha). The amount of fresh biomass production from the primary crop plants until Ratoon II was determined by the potential production of fresh biomass/ha and ratooning capability of the sorghum genotype. The fresh biomass production of the sorghum genotype was correlated with the plant height and the date of flowering.

The research was conducted in Solokuro Village, Lamongan Regency, East Java, from September 2016 to January 2017. It aimed to know the competitiveness of advanced hybrid line of NASA 29. Genetically, the advanced hybrid line of NASA-29 has the superiority in the number of cob compare with the dominant varieties that planted by farmers.The result of the preliminary adaptation study indicated that the prolific charateristic reaches 70%, but in the Solokuro Village, Lamongan Regency just reach 10% due to drought stress at the beginning of growth, but the other superiority such as the size of cobs, good pollination and sturdiness stems are more superior then dominant existing varieties. Yield potential was equaled with several varieties such as DK-959 and BISI-2, even more than the varieties of PAC-339 and NK-33, so that NASA-29 is economically andÂ profitably. Ratio revenue and cost of NASA-29Â highest than other varieties.Â Then the farmersâ€™ preferences on cob zise and yield potential of Nasa-29 are better than existing varieties. Therefore, NASA-29 has a prospect to developing in the future.

Aromatic rice is popular for its aroma, taste, and texture. The chemical compound of 2-Acetyl-1-pyrrolina (2AP) contributes to the pandan leaf-like aroma, while the hexanal compound is used as an indicator of rancidity in rice. Grains of three aromatic rice varieties, namely Mentik Wangi, Pandan Wangi, and Sintanur were milled in three degree of milling, i.e., 100, 90, and 0% (brown rice). The milled rice and the brown rice were then stored in hermetic bags and plastic bags for 4 months at room temperature. Chemical composition of the packed and stored rice grains were determined by the proximate analysis, including moisture content, ash content, fat content, protein content, and amylose content. The analysis was conducted at the beginning and the end of month of storage. Consumer preference test of the packed rice was done by the hedonic test. Moisture, ash, protein and fat contents during storage were still in the standards range. Compared to the amylose content prior to storage, the textures of the cooked rice after four months of storage remained fluffier or became less fluffy. The aroma, tenderness, texture, flavor, and overall attributes, judged by the panelists, Mentik Wangi was the most favored, followed by Sintanur and Pandan Wangi. Both hermetic bag and plastic bag gave no different effects on the stored rice quality and on the consumer preferences.

Research on the effect of packaging material for aromatic rice quality and its life storage was carried out. The aromatic rice varieties i.e Pandanwangi, Sintanur and Mentikwangi (each 750 kg) were dried in box dryer at 45oC for 12 hours. The dried paddy was milled at commercial milling to produce milled rice. The milled rice then were packed in high density polypropylene (HDPP), super bag and plastic sac. Factorial treatments were arranged in a completely randomized design, replicated thrice. The first factor was aromatic rice varieties (Sintanur, Mentikwangi and Pandanwangi) and the second factor was packaging material (superbag, high density polypropylene (HDPP) and plastic sac). Each treatment consisted of 5-7 kg of milled rice, kept in the room condition for six months. The physical, chemical characteristic, organoleptic test, and flavor composition were observed at the beginning, the middle and the end of storage. The result showed that physical quality of rice decreased parallel with the duration of storage. The whiteness, transparency and milling degree of rice kernel decreased as the period of storage increased. The infestation of insect in storage was found at 60 days after storing (at the second month) and tended to decrease parallel with insect life cycle. The used of plastic sac as packaging was invested by insect more than those of super bag and high density polypropylene. Therefore plastic sac was not recommended for packaging of aromatic rice at room condition. Organoleptic test indicated that cooked quality of aromatic rice decreased parallel with storing time. Based on colour, aroma, taste and texture, aromatic rice should be consumed within 90 days. After 90 days, the colour, aroma, taste and texture of the cooked rice was less preferred by panelis. The uses of plastic sac to pack aromatic rice produced cooked rice less preferable than those of super bag and high density polypropylene plastic.
