The use of indonesian soybean variety with time and planting location to the production to meet the demand

Based on data from the Central Bureau of Statistics, Jakarta [1], Ministry of Agriculture and Preliminary Study of National Medium-Term Development Plan (RPJMN) on food and agriculture, stage III, 2015-2019 [2] the demand for soybeans in Indonesia will remain increasing by the population growth. The author's research [3] previously concluded that efforts to increase the number of Indonesian soybean production include utilizing abandoned land and planting throughout the year. This study acts as a verification of previous research by using planting of Indonesian varieties of soybean in various time and planting location in order to meet the demand for soybean commodity. This research was conducted by experiment using 3 superior varieties with 3 planting time, which is planted in 3 sub districts of Malang regency, East Java province, Indonesia. Data Processing and analysis use experimental design that is latin square design with 95% confidence level. The results obtained that the use of different varieties with different planting time and location has no effect on the production. The different production result is on account of the fact that each variety has its own profile.

The Argentine portion of the soybean commodity chain

Since the 1990s the soybean crop has increased in the Southern Cone of Latin America (LA). During this time, Argentina, Brazil, Uruguay, Bolivia and Paraguay have become soybean producers. This phenomenon was influenced by the rising soybean demand from China for use in animal feed as the country changed its diet patterns. South American soybean exports to China constitute an important percentage of the bilateral commerce. Basically, two views can be identified with regard to China’s relations with LA countries. One of them emphasizes opportunities for building mutually beneficial relations and underscores the economic complementarity between both regions. Yet, the critical literature on China and Latin American relations draws attention to the contradictions of this process by highlighting the deepening of neo-extractivism and the expansion of the agricultural frontier. Describing the Argentine portion of the soybean commodity chain this paper will present data to support this critical literature. It depicts the actors, strategies and the degree of monopolization of each of the nodes of soybean production based on secondary data. The article’s key findings are as follows: (1) there is high monopolization and foreignization of soybean production and commercialization; (2) as China has become a global player in genomics and agrochemicals, it has reproduced the same patterns as the core countries; (3) despite the win-win diplomatic statements of the People’s Republic of China, there are important asymmetries in trade, and the Argentine deficits have continually increased; (4) by expanding GM soybean production, Argentina has augmented the concentration of land, primarization and transnationalization of the economy and monoculture; (5) the Cristina F. de Kirchner progressive government failed to stop soybean expansion, and with the drop of the economic growth rate that is associated with the fall of commodity prices combined with the restriction of access to international credits, the government was put in check by various fronts. The distributive conflict contributed to the increasing social confusion that led to a right wing recovery in 2015. Therefore, this article shows that China’s increasing trade with Argentina in the soybean sector follows the existing structure of the global commodity chain and does not offer much space for progressive change in Argentina’s political economy. The data that are presented demystify Chinese win-win statements and counter expectations about China as an alternative globalizer that would bring more benefits to the global South than traditional core countries have.

Property Rights and the Soybean Revolution: Shaping How China and Brazil Are Telecoupled

China currently has the largest population in the world and is currently experiencing rapid economic and urban growth, becoming the world’s number one pork and poultry consumer. In order to meet this growing demand for meat, China has increased its demand for soybeans to produce chicken and pork. It has imported soybeans from the United States, Brazil, and Argentina, while keeping its soybean production for direct human consumption stable at home. Brazil has become the largest soybean exporter to China, and, in response specifically to Chinese demand, has become the second largest producer of soybeans in the world. This has changed land use in Brazil, particularly in its central plateau. In this paper, we indicate how these two countries, telecoupled by trade in soybeans, are depending on each other as they try to balance environmental and economic objectives. Brazil, as a sending system, has created pressures on its natural ecosystems, which have led to losses particularly in the Cerrado biome and its ecotones in the Amazon’s tropical moist forest biome. China, as a receiving system, has created a land asset important to regenerating its lost natural systems (e.g., forest cover areas). Both countries have different property rights regimes, which have created distinct circumstances in which they are to protect or regenerate their natural ecosystems. Throughout this paper, we analyze how both countries have dealt with the lure offered by the soybean commodity trade.

The main objectives of this paper are to investigate the government pric policy and its implication on the soybean farming competitiveness; and formu late policy alternatives to enhance the soybean commodity competitiveness i agro-industry sector. This study was conducted in soybean farming center at th Grajagan Village, Purwohardjo district, Banyuwangi regency. The site was Se lected based on the Location Quotient analysis. The research method.used i this study is Policy Analysis Matrix (PAM). The result of the study are as follows price policy of the soybean commodity system could produce production surplu hy 4 %. This surplus enables producers to compete in the domestic market. 7 face the free trade, this policy could only achieve potential income of farming b 77 % and tempe-tofu industry by 91 %. With the current price policy, the soybea commodity still has an advantage showed by the comparative advantage wit the DRCsodaivalue of Rp 6.253 and domestic resource cost coefficient (CDRCria value of 0.67 as well as competitive advantage with the value of R, 6.888 and the domestic resource cost coefficient (CDRC,,,,,,,,,) value of 0.74. Gal eminent price policy for soybean commodity does not provide incentive for th development of the tempe-tofu industry. This is shown by the Effective Protectio and Profitability Coefficients (EPC and PC) which is less than 1 and the nega tive Subsidy Ratio to Producers (SRP) for both farming and agro-industry. An other policy alternative for increasing the soybean commodity competitivenes in agro-industry development is by increasing the productivity and output pric protection at the farmers level. Another policy alternative is the subsidy of fertil izer and pesticide whenever other countries have the same policy.

STRATEGI PENGEMBANGAN USAHATANI KEDELAI DI KABUPATEN GROBOGAN DENGAN PENDEKATAN ANALYSIS HIERARCHY PROCESS (AHP)

<p>Soybean is one of the agricultural commodity Grobogan. Soybean commodity is widely cultivated by farmers because the topography is consistent with the characteristics of the soil in Grobogan. In 2010 soybean production Grobogan is most widely in Central Java. However, Indonesia is still dependent on imported soybeans, especially in times of shortages of soybeans. This is partly also due to soybean production in soybean-producing region is very volatile while soybean demand in the market tends to increase. So, we need a strategy development of soybean farming in Grobogan. The goals to be achieved from the preparation of this study was to analyze the condition of soybean farming in Grobogan and obtain soybean farming development strategy in Grobogan based approach Analysis of Hierarchy Process. Alternative measures a priority to develop soybean are: Provision of continuous production factors and affordable, production factor subsidies, assistance to farmers, extension and education on effective post-harvest handling, Counseling institutional strengthening of farmer groups, and technical assistance (equipment, factors of production, training) to farmers. sedagkan least priority are: Incentives for active farmer organizations, cooperatives Revitalization and extension services and farmer partnerships with major employers</p><p><strong>Keywords: </strong>Soybean, Analysis of Hierarchy Process<strong></strong></p>

Direct stacking of sequence-specific nuclease-induced mutations to produce high oleic and low linolenic soybean oil.

BackgroundThe ability to modulate levels of individual fatty acids within soybean oil has potential to increase shelf-life and frying stability and to improve nutritional characteristics. Commodity soybean oil contains high levels of polyunsaturated linoleic and linolenic acid, which contribute to oxidative instability – a problem that has been addressed through partial hydrogenation. However, partial hydrogenation increases levels of trans-fatty acids, which have been associated with cardiovascular disease. Previously, we generated soybean lines with knockout mutations within fatty acid desaturase 2-1A (FAD2-1A) and FAD2-1B genes, resulting in oil with increased levels of monounsaturated oleic acid (18:1) and decreased levels of linoleic (18:2) and linolenic acid (18:3). Here, we stack mutations within FAD2-1A and FAD2-1B with mutations in fatty acid desaturase 3A (FAD3A) to further decrease levels of linolenic acid. Mutations were introduced into FAD3A by directly delivering TALENs into fad2-1a fad2-1b soybean plants.ResultsOil from fad2-1a fad2-1b fad3a plants had significantly lower levels of linolenic acid (2.5 %), as compared to fad2-1a fad2-1b plants (4.7 %). Furthermore, oil had significantly lower levels of linoleic acid (2.7 % compared to 5.1 %) and significantly higher levels of oleic acid (82.2 % compared to 77.5 %). Transgene-free fad2-1a fad2-1b fad3a soybean lines were identified.ConclusionsThe methods presented here provide an efficient means for using sequence-specific nucleases to stack quality traits in soybean. The resulting product comprised oleic acid levels above 80 % and linoleic and linolenic acid levels below 3 %.Electronic supplementary materialThe online version of this article (doi:10.1186/s12870-016-0906-1) contains supplementary material, which is available to authorized users.

Assessing the nutritional value of an enzymatically processed soybean meal in early juvenile red drum, Sciaenops ocellatus L

We assessed the nutritional value of an enzymatically processed soybean meal (HP300, Hamlet Protein Inc., Findlay, Ohio, USA; hereafter ESBM) in the diet of red drum, Sciaenops ocellatus. A digestibility and two growth trials (Trials I and II) were conducted to: i) assess the in vivo digestibility of ESBM and commodity soybean meal (SBM); ii) assess the maximum replacement of the digestible protein (DP) from fishmeal (FM) with ESBM (MAX REPLESBM); iii) validate the estimated MAX REPLESBM and compare it against SBM. All experimental diets were formulated to contain 32% DP, 12% lipid, and an estimated 13.8kJg−1 digestible energy. Seven experimental diets were designed in Trial I: a FM reference diet (FM-100), designed to contain all its protein from Special Select menhaden FM; and six test diets designed to replace the DP from FM in the FM-100 diet on a isonitrogenous basis, at 15% incremental levels (ESBM-15 to ESBM-90). Each diet was fed to juvenile red drum (5.72g) in duplicate aquaria connected as a closed recirculating system. After 6weeks of feeding, responses of red drum fed the various diets differed considerably, with survival ranging from 78 to 95%, final weight from 24.5 to 40.0g, weight gain (% of initial) from 330 to 597%, and feed efficiency (FE) from 0.7 to 1.0. Second order polynomial regression analysis of weight gain and FE data indicated a MAX REPLESBM of 72 and 63%, respectively. After feeding the FM-100, ESBM-70, and a SBM-70 diets to juvenile red drum (1.7g) in Trial II (8weeks, n=3), no differences in production performance of fish were found among treatments. These results indicated that either ESBM or SBM can replace up to 70% of FM DP in the diet of early juvenile red drum without detrimental effects on production performance. Statement of relevanceThe currently study represents an addition to the increasing number of studies evaluating alternative protein sources in the diet of carnivorous fish species. We used red drum as a model and demonstrated the applicability of soybean products as partial substitutes for dietary fishmeal. Once replicated under commercial production settings, our results will contribute for a more sustainable aquaculture industry.

Production performance and non-specific immunity of cage-raised red drum, Sciaenops ocellatus, fed soybean-based diets

Abstract A 15-week feeding trial was conducted to evaluate the replacement of fishmeal (FM) with soybean products (SP) in the diet of advanced juvenile red drum, Sciaenops ocellatus . Two dehulled, hexane-extracted SP were evaluated: commodity soybean meal [SBM; 48% crude protein (CP)] and Navita 3010 [N-3010; produced from non-genetically modified, selectively bred varieties; 54% CP]. The additive effect of a prebiotic (GroBiotic®-A; GBA) on the overall performance of red drum also was evaluated. All diets were formulated to contain 35% digestible protein (DP), 15% lipid, and an estimated 3.5 kcal DE kg − 1 . The reference diet was formulated to contain 44.6% Special Select® menhaden FM and 15.0% corn protein concentrate (CPC). Three test diets (SBM, SBM + GBA, and N-3010) were formulated to contain 6.0% FM and 15.0% CPC, together providing approximately 38% of the dietary DP. The remaining 62% DP was provided by 5.7–5.8% soy protein concentrate (SPC) and the specific SP treatment. Diets were fed to apparent satiation to advanced juvenile red drum (mean ± SD = 68 ± 5.1 g initial weight) in each of four replicate 1-m 3 floating-cages. After 15 weeks of feeding, no significant differences were found among treatments for all growth performance and non-specific-immunity parameters evaluated. Based on these results, SBM or N-3010 in combination with SPC can replace approximately 86% of the DP provided by FM in the diet without negatively affecting production performance and health status of advanced juvenile red drum.

Partial replacement of fishmeal, poultry by-product meal and soy protein concentrate with two non-genetically modified soybean cultivars in diets for juvenile cobia, Rachycentron canadum

Fishmeal (FM) replacement in diets for intensive aquaculture has become a high priority area for the global aquaculture industry. In this study, a twelve week growth trial was conducted with juvenile cobia (18 g initial weight) to examine the effects of non-genetically modified soybean meals as potential replacement protein sources. Genetically modified (GM) crops and their intended and unintended effects have become major topics of controversy worldwide, with several regions banning their use in food and feeds. Therefore, it is especially critical to develop and evaluate non-GM feedstuffs for use in aquaculture diets where GM products are prohibited as the global aquaculture industry continues its expansion to meet increasing demands. Navita Premium Feed Ingredients (NPFI's) 3010 solvent extracted meal and 3032 cold-pressed cake meal were utilized to replace 50, 60 or 70% and 40, 50, or 60% of FM protein, respectively and were compared to a FM based reference formulation. None of the experimental diets performed significantly different from the reference diet in terms of weight gain (WG) or specific growth rate (SGR). However the 3010 50% diet performed significantly better than the 3032 50 and 60% diets in regard to WG, SGR, and protein efficiency. There were no significant differences between the seven diets at the conclusion of the trial in regard to their effects on filet quality as determined by organoleptic testing. These two non-GM soybean protein sources appear to be valuable FM replacement options for juvenile cobia, with none of the typical indicators of intestinal enteritis developing as has been observed in various other teleost species when high quantities of commodity soybean meal have been utilized.

Thirteen week rodent feeding study with processed fractions from herbicide tolerant (DP-Ø73496-4) canola

The potential health effects of meal and oil processed from seed of genetically modified (GM) canola plants (OECD unique identifier: DP-Ø73496-4; hereafter referred to as 73496 canola) containing an insert that expresses the GAT4621 protein conferring tolerance to nonselective herbicidal ingredient glyphosate were evaluated in a subchronic rodent feeding study. Sprague–Dawley rats (12/sex/group) were administered diets containing dehulled, defatted toasted canola meal (DH meal) and refined/bleached/deodorized canola oil (RBD oil) processed from seed of plants that were untreated (73496), sprayed in-field with glyphosate (73496GLY), the non-transgenic near-isogenic (091; control), or one of four commercially available non-GM reference canola varieties (45H72, 45H73, 46A65, 44A89). All diets were formulated as a modification of the standard laboratory chow PMI® Nutrition International, LLC Certified Rodent LabDiet® 5002 (PMI® 5002). DH canola meal and RBD canola oil replaced all commodity soybean fractions typically incorporated in PMI® 5002. No toxicologically significant differences were observed between the test and control groups in this study. The results reported herein support the conclusion that DH meal and RBD oil processed from seed of 73496 canola are as safe and nutritious as DH meal and RBD oil processed from seed of non-GM canola.

Replacement of fish meal by a novel non-GM variety of soybean meal in cobia, Rachycentron canadum: Ingredient nutrient digestibility and growth performance

A constraint for the expansion of cobia aquaculture is the availability of high quality formulated diets which reduce or eliminate fish meal (FM) protein. Therefore, the nutritive value of a novel soybean cultivar, Navita™ (Navita, non-genetically modified and selectively bred soy), and regular, commodity soybean meal (SBM, de-hulled, defatted, roasted and solvent-extracted) was evaluated for cobia, Rachycentron canadum via separate digestibility and growth trials. In the first experiment Navita's apparent digestibility coefficients (ADC) were higher than those of SBM for nearly every nutrient evaluated. Crude protein ADCs were 82 and 69% for Navita and SBM, respectively. Apparent DC for amino acids ranged from 68 to 109% for Navita whereas, amino acid ADCs for SBM varied from 42 to 98%. The feeding trial utilized fish of a size that more closely resembles commercial cobia stocking (1.8kg), and was conducted over a 91-day period. Experimental diets (iso-nitrogenous and iso-energetic) were formulated such that 67% of the FM protein in the reference diet was replaced by either a combination of SBM+soy protein concentrate (SPC, Solae Profine®) labeled MXSB-diet, or by a combination of SPC+Navita; Navita-diet, hereafter. A fourth experimental diet had 80% of the FM protein replaced by a combination of Navita+SPC and was identified as Navita-high. No significant differences (P>0.05) were observed in fish fed the experimental diets for feed conversion ratio, protein efficiency ratio, feed efficiency, mean daily intake, gross protein intake, gross energy intake, visceral somatic index, muscle ratio, and hepatosomatic index. Fish fed the Navita-high diet had the lowest fish in:fish out ratio (FIFO) at 0.9±0.16. These results indicate that Navita meal can be incorporated at very high levels in the diet of marine carnivorous fish such as cobia with no detriment to performance, making it a prime candidate for FM replacement in aquafeeds.

Production of Isotopically Labeled Standards from a Uniformly Labeled Precursor for Quantitative Volatile Metabolomic Studies

Optimal accuracy and precision in small-molecule profiling by mass spectrometry generally requires isotopically labeled standards chemically representative of all compounds of interest. However, preparation of mixed standards from commercially available pure compounds is often prohibitively expensive and time-consuming, and many labeled compounds are not available in pure form. We used a single-prototype uniformly labeled [U-(13)C]compound to generate [U-(13)C]-labeled volatile standards for use in subsequent experimental profiling studies. [U-(13)C]-α-Linolenic acid (18:3n-3, ALA) was thermally oxidized to produce labeled lipid degradation volatiles which were subsequently characterized qualitatively and quantitatively. Twenty-five [U-(13)C]-labeled volatiles were identified by headspace solid-phase microextraction-gas chromatography/time-of-flight mass spectrometry (HS-SPME-GC/TOF-MS) by comparison of spectra with unlabeled volatiles. Labeled volatiles were quantified by a reverse isotope dilution procedure. Using the [U-(13)C]-labeled standards, limits of detection comparable to or better than those of previous HS-SPME reports were achieved, 0.010-1.04 ng/g. The performance of the [U-(13)C]-labeled volatile standards was evaluated using a commodity soybean oil (CSO) oxidized at 60 °C from 0 to 15 d. Relative responses of n-decane, an unlabeled internal standard otherwise absent from the mixture, and [U-(13)C]-labeled oxidation products changed by up to 8-fold as the CSO matrix was oxidized, demonstrating that reliance on a single standard in volatile profiling studies yields inaccurate results due to changing matrix effects. The [U-(13)C]-labeled standard mixture was used to quantify 25 volatiles in oxidized CSO and low-ALA soybean oil with an average relative standard deviation of 8.5%. Extension of this approach to other labeled substrates, e.g., [U-(13)C]-labeled sugars and amino acids, for profiling studies should be feasible and can dramatically improve quantitative results compared to use of a single standard.

International trade and productivity of China’s soybean commodity: Trade policy simulations by GTAP

This study explores China’s soybean trade and production since soybean is an important commodity in China’s consumption market. It uses data envelopment analysis (DEA) to measure the productivity of China’s soybean, and then based on the DEA results it applies Global Trade Analysis Project (GTAP) to simulate China’s soybean import change concerning both potential productivity change and the pressure of currency upvaluation of RMB (Chinese Yuan). It appears that, with the currency upvaluation of RMB, North American Free Trade Area (NAFTA) would be the biggest beneficiary from China’s soybean oil seeds imports even if China’s soybean producers could improve their efficiency. Key words: Soybean, production, productivity, data envelopment analysis (DEA), trade, import, GTAP, efficiency.
