Accelerated Aging Machine â€œIPB 77-1 MMâ€ could be used for soybean seed screening based on the seed storability vigor. The aim of the research was to identify simple, fast and accurate accelerated aging method using accelerated aging machine IPB 77-1 MM. Two methods of accelerated aging test (physical and chemical treatment) were applied to seeds of Anjasmoro soybean variety. The best accelerated aging method was then used to screen seed storability vigor of 23 soybean varieties. Seed storability vigor of 23 soybean varieties were detected using accelerated aging machine IPB 77-1 MM and each was compared with the seed storability vigor of those stored 10 weeks in controlled storage. Results of the experiment showed that using chemical or physical treatment on accelerated aging process were able to decrease seed vigor, but chemical treatment decreased seed vigor faster, more simple and more practical. Accelerated aging machine IPB 77-1 MM could also be used for screening varietal seed storability vigor of soybean using electrical conductivity test.

Rate of NPK fertilization on rice using NPK compound fertilizer needs to consider soil nutrient status and plant nutrient requirement. The research was aimed to determine the optimum rate of compound fertilizer and the effect of enriched S nutrient of NPKS compound (15-15-15-5S) and NPK compound fertilizer (15-15-15) on the growth and yield of rice. The experiments were conducted at two sites in Galuga, Ciampea Bogor, West Java from April to September 2013, using randomised complete block design with 3 replications. Experiment at site I consisted of 9 treatments: six levels of fertilizers NPKS i.e. 0; 150; 300; 450; 600; and 750 kg/ha, standard fertilizer, NPK compound fertilizer equivalent to standard, and standard fertilizer plus S. Rate of urea, SP-36, and KCl for standard fertilizer treatment was respectively 250, 75, and 50 kg/ha. At site II the treatments consisted of 6 levels of NPK compound fertilizer i.e. 0; 150; 300; 450; 600; and 750 kg/ha and the standard fertilizer with rate of 250 kg/ha of urea, 50 kg/ha SP-36, and 75 kg/ha KCl. Plot size was 4 m x 5 m planted with Ciherang variety. Data collection included chemical properties of soil before and after the experiment, plant height, number of tillers, straw weight, and dry grain weight and the nutrient uptake. The effectiveness of fertilizer was calculated by RAE (Relative Agronomic Effectiveness). Results showed that fertilizer NPKS (15-15-15-5S) at 600 kg/ha effectively increased dry grain weight from 3.63 t/ha to 4.67 t/ha, but was not significantly different from a standard fertilizer treatment. It increased dry grain weight by 29% compared to control. NPK fertilizer (15-15-15) effectively promoted growth and dry grain weight equivalent to standard fertilizer at rate of 300-750 kgha. The optimum rate of NPK compound fertilizer (15-15-15) was 440 kg/ha as was shown with the production performance of 4.12 t/ha with RAE by 58%. NPKS compound fertilizer with rate of 750 kg/ha showed the highest uptake of N, P, and K nutrients and significantly increased the available P in the soil. Whereas NPK compound fertilizer with a rate of 600 kg/ha indicated the highest P nutrient uptake. Fertilizer enrichment with sulfur on NPKS fertilizer (15-15-15-5S) did not significant affect on grain dry weight.

The study was aimed to obtain the information on the genetic diversity on agronomic traits of wheat among the F3 and F4 generations, derived from crosses of Oasis x HP1744, planted at the highland and medium elevation. The second objective was to acquire the character for selection and to acquire the adaptable genotypes on the highland and on the plain medium elevation. Selection was carried out using Shuttle Breeding, where F3 generation was selected at the Experimental Station of Cipanas (1100 m asl) and F4 generation was selected at the plain medium elevation of Cisarua (600 m asl). The experiment used Augmented Designs. Genetic material consisted of 57 F3 pedigree families selected from the F2 generation of Oasis x HP1744 cross plus six check varieties. The F4 generation cinsisted 320 selected genotypes from the F3 generation plus six check varieties. Plant height, flag leaf area, percentage of empty florets per panicle, number of grains/panicle and grain weight/panicle of the F3 generation showed larger mid value than the two parents. In the F4 generation, flag leaf greenness, total number of tillers, number of productive tillers, main panicle seed weight, number of seeds/panicle, seed weight/panicle, number of seeds/plant and seed weight/plant indicated the mean value larger than that of the Oasis. Plant height, number of productive tillers, days to flowering, maturity, spikelet number, and the total number of florets of the F4 generation showed higher heritability than that of F3 generation. Character suitable for indirect selection in the F3 was plant height, which indicated the best indirect differential selection. Potential families for further selection included: O/HP 21, O/HP 82, O/HP 12, O/HP 100 and O/HP 28. Characters most suitable for indirect selection in the F4 generation were: main panicle seed weight which indicated the best indirect differential selection. Genotypes potential for further selection in the medium elevation were O/HP82-19; O/HP82-15, O/HP78-5, O/HP49-30 and O/HP78-2.

The use of transgenic varieties on the agricultural production system may provide some agronomical benefits. However, uses of transgenic variety have raised some debates about their potential negative impact on the environment, such as on the decreasing of natural enemies. To study the impact of transgenic variety to the natural enemies, study was conducted on larvae development, and the survival of predatoral insect (V. lineata) on the transgenic Rojolele rice variety. Test was conducted at the laboratory of Molecular Biology, Research Centre for Biotechnology of Indonesian Institute of Science, from January to October 2009. Completely randomized design with 8 treatments and 30 replications were employed. The treatments were transgenic Rojolele rice as follow: 4.2.3-28-15-2-7 and 4.2.4-21-8-16-4 lines contained fusion of two cry genes (cryIB-cryIAa). The 3R9-8-28-26-2 and 3R7-8-15-2-7 lines contained mpi::cryIB gene, the T9-6.11-420 line contained cryIAb gene obtained by particle bombardment, DTcry (azygous) is a segregate and does not contain cry gene (null), DTcry-13 line contained cryIAb gene by Agrobacterium, and non transgenic rice (Rojolele variety). Results showed that there were differences of larvae development and survival of insect predator V. lineata fed on the among transgenic rice lines. On transgenic line T9-6.11-420 and on DTcry-13 line the life time, developmental stages, the number eclosion of adult female, adult insect weight, and survival of the preimaginal and the adult of insect predator were consistently low. On the transgenic line 4.2.3-28-15-2-7; 3R9-8-28-26-2; and 3R7-8-15-2-7 each had no consistent effect on the larvae development and the survival of insect predator. DTcry (azygous) line had no effect on the larvae development and the survival of insect predator. Whereas transgenic line 4.2.4-21-8-16-4 had an effect on the adult weight of insect predator.

Intensity and quality of sunlight received by plants during the reproductive period greatly influence the soybean yield and yield components. Growth and seed yield of soybean genotypes at different shade intensities were assessed through research conducted at the Research Station of Kendalpayak, Malang, in the year 2011. Three soybean varieties, namely: Pangrango, Argomulyo, and Grobogan, and twelve soybean promising lines tolerant to shade were tested on four artificial shade intensities, ie without shade (N0), shade of 25% (N1), 50% (N2), and 75% (N3). Placement of treatments in each level of shade was arranged in a randomized block design, replicated three times. Results showed that: shade treatment changed the microclimate under the shading. Shade treatment of 25%, 50%, and 75% caused different stress intensities. Shade intensity of 75% caused an increase in plant height and specific leaf area, a reduction in the number of leaves and leaf area, photosynthetically active radiation (PAR) absorption rate, photosynthetic rate, leaf chlorophyll index, number of filled pods, and seed weight per plant. Number of filled pods was considered effective to be used as a basis for selecting soybean genotypes having high yield in shaded conditions. Plant height and seed weight could be used as an indicator for soybean shade tolerance. Genotype AI26-1114-8-28 and IIj9-299-1-4 were considered as shade-tolerant up to 75% shade based on the stress index tolerance value (ITC).

The prediction of national soybean yield and production could be improved its accuracy by integrating a simulation model and Geographic Information Systems (GIS). The objective of this research was to integrate a simulation model with a GIS, to predict the potential yield and production of soybean in the soybean production centers of East Java. This study was conducted from December 2013 till May 2014. The approach used in this study was a systems approach using a simulation model as solution to the problem. The model is SUCROS.SIM (Simple Universal Crops Growth Simulator), which was written using Powersim software and Spreadsheet in order to be fully integrated with GIS. The initial phase of the integration process between SUCROS.SIM and GIS are as follows (a) model validation, using input data of soybean plant assimilate partitioning, (b) climatic data (solar radiation, maximum and minimum temperatures) collected from the climatological station (BMKG) Karangploso Malang and (c) observation data of soybean yields of two varieties (Wilis and Argomulyo) at Muneng Experiment Station. It was found that the coefficients of determination of simulation model of soybean yield potential (R2) range from 0.945-0.992 and RMSE (Root Mean Square Error) values range from 0.11 to 0.25 t/ha. The average of soybean yield potential and production in 2012 at soybean production centers of East Java were 1.94 t/ha and 293,459 ton, respectively. The conclusion is SUCROS.SIM valid to be integrated with GIS.

Soybean seed viability declines during seed storage. Soybean seed deteriorates rapidly, affected by its high protein content and often high humidity in the tropical environment. This research was aimed to develop dynamic model of soybean seed viability in an open storage. The study was conducted in three stages, namely: 1) desk study, 2) seed storage experiment, 3) development of seed storage model, simulation and verification of the model. The second stage of the experiment consisted of soybean seed storing and germination testing using completely randomized design. Treatments were three initial moisture content (7-8%, 9-10% and 11-12%) and four varieties of soybean (Anjasmoro, Wilis, Detam-1 and Detam-2). The results showed that the seed behaviour during storage period were affected by initial seed moisture content, initial viability, varieties and environmental condition. Therefore, seed moisture content, initial viability and varieties may be used as input model. Moisture content, integreting seed respiration, electric conductivity and seed storability vigor (VDSDB) were as model output. Simulation of Seed Storability Vigor Prediction Model with Model Construction Layer-Stella (MCLS) using relative humidity (RH), temperature, seed permeability, initial moisture content and initial viability as input model could logically predict the seed moisture content and seed storability vigor (VDSDB).

IAARD in collaboration with IRRI has developed site specific nutrient management (SSNM or PHSL) recommendation, which can be accessed through PHSL-web (http:/webapps.irri.org/nm/id). PHSL recommendations were evaluated for inbred rice variety but not yet for hybrid rice. The objective of this experiment was to verify the effectiveness of PHSL recommendation for hybrid rice and to evaluate the response of hybrid rice to N fertilizer. Two experiments were conducted during the dry season of 2012 in two locations (Malang and Blitar). The first experiment consisted of 6 treatments: (1) PHSL recommendation based on yield target of hybrid variety (Mapan-P05) (10.3 t/ha or 20% higher compared to that of inbred variety), (2) same as treatment 1 for Hipa-10 hybrid variety, (3) same as treatment 1 for Ciherang variety, (4) PHSL based on the yield target similar to that of inbred variety (8.6 t/ha) applied for Mapan-P05 hybrid variety, (5) same as treatment 4 applied for Hipa-10 hybrid variety, and (6) same as treatment 4 applied for Ciherang inbred variety. PHSL recommendation for hybrid rice was 300 kg NPK (Phonska) + 376 kg urea/ha applied 4 times, while that for inbred rice was 200 kg NPK (Phonska) + 332 kg urea/ha applied 3 times. The experiment was arranged in a randomized complete block design, 4 replications, and plot size was 5 m x 10 m. The second experiment was arranged in a split plot design with four replications and plot size 5 m x 10 m. The main plots consisted of 4 rates of urea application namely: 0; 150; 300; and 450 kg urea/ha. The sub plots were two varieties namely: Mapan-P05 (hybrid) and Ciherang (inbred). Soil was analyzed before the conduct of experiment. Main data collection included yield of rice, hybrid rice respon to urea fertilizer. Results of the experiment showed that fertilizer rate based on PHSL for hybrid rice was not appropriate. Applying rate of fertilizers based on PHSL for hybrid rice resulted in rice yields not significantly different to that of inbred variety fertilized based on PHSL for inbred variety. The response of hybrid variety to N fertilizer was higher than that of inbred variety, suggesting that hybrid rice produced higher yield than did inbred, at the same rate of fertilizer. To obtain a higher yield of hybrid rice (such as Mapan-P05) the rate and time of fertilizer applications are not necessarily to be increased as recommended on PHSL-web. Using the same fertilizer rate, hybrid rice (such as Mapan-P05) produced higher yield compared to that of inbred variety, which indicated higher efficiency of fertilization. Yield of hybrid rice Hipa-10 variety was not only determined by fertilizer rate but also by other factors, such as seed quality and crop management (M). The existence of GxExM interaction was higher for hybrid rice, meaning hybrid variety required very specific environment.Keywords:Â
