Abstract:
The objective of this review was to carry out a scientific systematization on the logistics of soybean chain in Brazil, focusing on losses during harvest, storage, and transport of soy, to demonstrate the economic impacts of losses in the soybean chain. The survey of works related to the theme was conducted in the bases Scopus, SciELO, and in the CAPES portal. In the development of the review, 10 articles were used about the logistics of soybeans in Brazil, 22 studies related to losses in the pre-harvest and soybean harvest, 22 involving soybean transportation and storage losses. The organization of the Brazilian soybean chain is complex due to soybean expansion and the territorial extension of Brazil. The pre-harvest and harvest losses are well explained, but significant losses still occur due to lack of regulation in the harvesters, which can be solved through the training of the operators. Concerning losses during transport and storage, studies are needed to quantify quantitative losses, as these losses may be determinant for the rural entrepreneur's profitability, as well as for the Brazilian competitiveness in the international market in terms of costs.

Abstract:
ABSTRACT Sourgrass (Digitaria insularis) is one of the main species causing significant losses in Brazilian soybean production systems. Thus, this paper aimed to evaluate sourgrass interference on soybeans grown under Cerrado conditions. Three field experiments were conducted, of which the first two (E1 and E2) simulated sourgrass after pre-sowing burndown, using plants already emerged by the time soybeans were sown; whereas the third (E3) simulated both sourgrass and soybeans emerged simultaneously. Both E1 and E2 were conducted in a randomized complete block design (RCBD) with five treatments based on sourgrass infestation densities (0, 2, 4, 6, and 8 plants m-2) and four replications. In turn, E3 was also carried out in an RCBD but with treatments arranged in a 2 x 5 factorial and four replications. The first factor comprised two soybean cultivars, while the second was sourgrass density levels, just as in E1 and E2. The results showed that increasing sourgrass densities reduced soybean yield regardless of the plant growth stage when the crop was sown. Yield losses were higher when sourgrass plants were already established by the time soybean was sown. Soybean yield losses reached up to 80% under higher sourgrass infestation levels.

Abstract:
The soybean aphid, Aphis glycines Matsamura (Hemiptera: Aphididae), is a pest of soybeans in the People's Republic of China, Korea, Thailand, Japan, North Borneo, Malaya, and the Philippines (Blackman and Eastop 2000). It was first identified in North America in 2000 from soybean fields in 10 states in the north-central United States of America, although the route of entry and time of introduction are not known (North Central Regional Pest Alert 2001). Dai and Fan (1991) reported that yield losses caused by soybean aphids on soybeans in the People's Republic of China were greater when the crop was infested soon after planting, and the presence of large populations of the aphid throughout the growing season resulted in 20%–30% yield losses. The soybean aphid can also transmit several viruses that infect soybeans in North America, including alfalfa mosaic, soybean mosaic, bean yellow mosaic, peanut mottle, peanut stunt, and peanut stripe (Hartman et al. 2001). In North America, the soybean aphid is known to transmit soybean mosaic virus and alfalfa mosiac virus (Hill et al. 2001). A survey of Ontario soybean fields revealed the presence of tobacco ring spot virus, soybean mosiac virus, and bean pod mottle virus (Michelutti et al. 2001); all of which could potentially be spread by this newly introduced aphid.

Abstract:
The objective of this current paper is to evaluate, in real production scale, the management of soybean batches in the storage unit of harvested grains that are submitted to drying processes with different technologies, such an evaluation can contribute to minimizing energy and qualitative losses, and to ensuring the grain quality and sustainability of the postharvest system. The experiment was realized in full-scale production and the treatments utilized were lots moist soybean crop (SUL), RR dry soybean (SSLRR), RR2 dry soybean (SSLRR2), dried soybean in continuous dryer (SSS1) (11.0%), dried soybean silo-dryer (SSS2) (12.5%), dried soybean in silo aerator (SSS3) (14.0%). Energy losses and grain quality as a function of drying management ranged from 2.5 to 16.4% in energy, from 0.23 to 3.26% in crude protein and 0.15 to 3.05% in oil—the maximum yield of wet soybeans harvested from the crop (SUL) at 17% (w.b.). Considering the annual Brazilian soybean production, energy losses reach up to 162,282.50 m³ of firewood, approximately 2,116,963,470 kg of crude protein and 810,616,800 liters of crude oil. This would ensure lower losses and higher grain quality, including better yield of protein and crude oil, specifically reducing energy impacts by increasing the efficiency of the drying system. The current study concluded that the SSS1 drying system reduces energy-environmental impacts by 80.23%, reduces crude protein losses by 94.73%, and crude oil by 95.08%.

Abstract:
Water erosion causes soil degradation, which is closely related to nutrient losses either in, the soluble form or adsorbed to soil particles, depending mainly on the adopted soil management system. This study was carried out in São José do Cerrito, SC, Brazil, between March 2000 and June 2001. The objective was to quantify available nitrogen, phosphorus, potassium, calcium and magnesium losses in water erosion obtained with simulated rainfall in the following soil management systems: conventional tillage with no-crop (bare soil) (BS), conventional tillage with soybean (CT), reduced tillage with soybean (RT), no tillage with soybean on a desiccated and burned natural pasture (DBNP), and no tillage with soybean on a desiccated natural pasture (DNP). A rotating boom rainfall simulator was used to perform three rainfall tests with constant intensity of 64 mm h-1 and sufficient duration to reach constant runoff rate, on a clayey-loam, well-structured Typic Hapludox, with an average slope of 0.18 m m-1. The first test was carried out five days before soybean emergence and the second and third at 30 and 60 days, respectively. The nutrient concentration in water and total losses of nitrogen, phosphorus, potassium, calcium and magnesium were higher under CT than in the other soil management systems.

Abstract:
Field studies using area-of-influence techniques were conducted in 1987 and 1988 to evaluate soybean growth and yield, and to predict soybean yield losses from photographs of jimsonweed and common cocklebur canopies. Differences in weed competitiveness within the 100-cm area of influence were induced by dates of soybean planting, locations, weed species, and years. Soybean yield losses within the first 20-cm interval from weeds correlated well with yield of all soybean plants within 100 cm of weeds (r2= 0.86). Soybean growth responses as a function of distance from weeds were best described by complex polynomials, but simple linear functions, based on a data point from soybean plants nearest a weed and from the average of plants 60 to 100 cm from a weed, closely approximately actual yield losses (r2= 0.96). Soybean yield losses were highly correlated (r2= 0.84) with leaf area of weeds as viewed from directly above the weed-crop canopy. Weed canopy diameter, measured from overhead photographs 8 weeks after soybean emergence, also correlated well with soybean yield losses (r2= 0.82), but correlation with actual weed leaf area was not significant (r2= 0.31).

Abstract:
Research must focus on management of diseases that cause extensive losses, especially when funds for research are limited. Knowledge of the losses caused by various soybean diseases is essential when prioritizing research budgets. The objective of this project was to compile estimates of soybean yield potential losses caused by diseases for each soybean producing state in the United States from 2006 to 2009. This data is of special interest since the 4-year period summarized in this report, permits an examination of the impact of soybean rust that was first reported in the United States in 2004. Thus, in addition to the goal of providing this information to aid funding agencies and scientists in prioritizing research objectives and budgets, an examination of the impact of soybean rust on soybean yield losses relative to other diseases is warranted. Yield losses caused by individual diseases varied among states and years. Soybean cyst nematode caused more yield losses than any other disease during 2006 to 2009. Seedling diseases, Phytophthora root and stem rot, sudden death syndrome, Sclerotinia stem rot, and charcoal rot ranked in the top six of diseases that caused yield loss during these years. Soybean yield losses due to soybean rust and Sclerotinia stem rot varied greatly over years, especially when compared to other diseases. Accepted for publication 21 October 2010.

Abstract:
The climate unpredictability causes long periods of drought, becoming the main risk factor in soybeans production fields and consequent losses to farmers in Brazil and worldwide. As sessile organisms, plants are constantly challenged by a wide range of environmental stresses, including drought. Growth constraints and stress due to these environmental changes result in reduced yield and significant harvesting losses. The response to abiotic stresses is a very complex phenomenon, since several stages of plant development can be affected by a particular stress and often several stresses affect the plant simultaneously. In order to mitigate the damages caused by the climate, new soybean cultivars adapted to the drought and the diversified climate are necessary, as well as technological advances in the production of soybeans that must advance with the increase of cultivated area. Therefore, the mechanisms underlying tolerance and adaptation to stress have been the focus of intensive research. In this sense, the objective of this review is to provide an overview of the evolution of genetic improvement regarding the search for more drought-tolerant cultivars, as well as to verify which strategies are used in the genetic improvement of soybean in the search of these genotypes.

Abstract:
Soybean disease loss estimates were compiled for the 1994 harvested crop from the 10 countries with the greatest soybean production. The objective was to document the major soybean disease problems in these countries and any recent changes in the severity of individual soybean diseases. Total yield losses caused by Heterodera glycines in these 10 countries were greater than those caused by any other disease. Next in order of importance were stem canker, brown spot, and charcoal rot. The total yield loss due to disease during 1994 in these countries was 14.99 million metric tons, valued at $3.31 billion. Methods used to estimate soybean disease losses were field surveys, plant disease diagnostic clinic samples, variety trial data, information from field workers and university extension staff, research plots, grower demonstrations, and private crop consultant reports. Yield loss estimates due to a particular disease varied by country. For example, yield losses due to rust were reported from China and Indonesia, but no losses due to this disease were reported from any of the remaining eight countries. Soybean disease control research and extension efforts are needed to provide more effective preventive and therapeutic disease management strategies and systems to producers.

Abstract:
Volunteer corn (Zea maysL. # ZEAMX) is a troublesome weed in soybeans [Glycine max(L.) Merr.] grown in the Corn Belt. Field studies were conducted in 1983 and 1984 at Champaign, IL, to determine the soybean growth and yield parameters affected by volunteer corn interference. Soybean yield was inversely and linearly related to volunteer corn clump density, with yield losses reaching 25% at 5380 clumps/ha (10 plants/clump). Volunteer corn clumps of 1, 4, 7, and 10 plants reduced soybean yields by 6, 16, 21, and 22%, respectively, at a density of 5380 clumps/ha. Treatments of either the butyl ester of fluazifop {(±)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy] propanoic acid} or glyphosate [N-(phosphonomethyl)glycine] were applied at various dates between 2 and 12 weeks after soybean emergence (WAE) to a volunteer corn infestation of 5380 clumps/ha (10 plants/clump). Volunteer corn caused soybean yield losses of 2, 6, 12, 19, and 27% when herbicides were applied at 2, 4, 6, 8, and 10 WAE, respectively. Volunteer corn interference reduced soybean seed yield, plant dry weight, pod number, seed number, leaf fresh weight, and leaf area index, within 40 cm of a clump of 10 volunteer corn plants. A clump of 10 volunteer corn plants reduced soybean pod number/plant within a radius of 86 cm.

Abstract:

Soybean, Glycine max (L.) Merr., is planted across a vast amount of land in the Mid-Southern U.S. (Arkansas, Louisiana, Mississippi, and Tennessee), and yield responses to defoliation can vary. Experiments were conducted during 2015-2017 evaluating how soybean yield responds to multiple and continuous defoliation, as well as planting date and plant population. Multiple defoliation events were evaluated by defoliating soybean at varying levels at V3, V6, and both growth stages. There was no interaction between defoliation occurring at V3 and V6 growth stages, indicating that the impact of each defoliation event was independent of the other. The effect of continuous defoliation was evaluated by defoliating soybean weekly, beginning at V2. Defoliation continued throughout the vegetative growth stages or throughout the entire growing season, and was compared to the same defoliation level occurring one time at R3. Continuous defoliation during vegetative growth stages only, did not reduce yield at any of the levels tested. Defoliation occurring throughout the growing season reduced yields more than a one-time defoliation event at R3, but only when defoliation levels exceeded the 20% defoliation threshold. This indicates that thresholds do not need to be modified to account for multiple or continuous defoliation. To evaluate the effect of planting date on yield loss from defoliation, soybean was planted at six planting dates beginning in early-April and continuing through mid-June. Each planting date included a defoliated treatment and an undefoliated control. It was determined that later planted soybean lose a greater amount of yield than earlier planted. Higher yielding soybean also lost more yield than lower yielding soybean at every planting date until Mid-June. It was concluded that late planted soybeans could benefit from a lower treatment threshold. The effect of plant population on yield loss from defoliation was evaluated by planting soybean at five populations ranging from 123,500 seeds/ha to 420,070 seeds/ha. A undefoliated control and a defoliated treatment was included for each plant population. Defoliation significantly reduced yields only where final plant populations were lower than 192,800 plants/ha. This indicates that fields with substandard plant populations are more susceptible to yield loss from defoliating pests.

Abstract:
Target spot is a foliar disease of soybean that can produce yield losses. The disease has recently become a concern due to increasing intensity of its epidemics in the main soybean growing countries (USA, Brazil and Argentina). The goals of this study were to i) estimate the target spot control efficiency and yield response of labeled fungicides for the main soybean growing region of Brazil and identify factors affecting their performance; ii) characterize the relationship between target spot severity and soybean yield using meta-analytic techniques, and to identify patterns which allow understanding the heterogeneity in the relationship; iii) to explore the variability of genetic resistance of cultivars and verify the less time-consuming methodology for doing it; iv) explore the pathogen-host interaction effects on the epidemic development; v) compare the sensitiveness of the canopy strata position injured by C. cassiicola to reduce grain yield. Fungicides containing fluxapyroxad + pyraclostrobin were the most efficient ones to control target spot, with control levels of 75% and their yield response depended on the disease pressure (DP, DPLow < 35% target spot severity at untreated checks <= DPHigh). At DPLow was unprofitable the use of fungicides and at DPHigh the latter fungicides had the best performances increasing yield relative to the untreated check in > 469 kg ha-1 (+19.1%). Potential yield of soybean in absence of target spot was estimated in 3507 kg ha-1 for 41 trials in Brazil and the percentual reduction for each target spot severity point was calculated in 0.48%, what would represent a reduction of 24% in a hypothetical target spot severity of 50% (ranging from 8% to 42%). The soybean cultivar had a significant effect to explain this wide range of responses: potential losses of 11%, 18.5% and 42% was calculated for cultivar BMX Potência RR, TMG803 and M9144RR respectively at target spot severity = 50%. We observed high variability on the genetic resistance in the tested germplasm: cultivars with very low target spot intensity (BRS360) to highly susceptible cultivars. A single-point disease severity assessment was not as reliably as an integrative three-point assessment, which had no difference with a less time-consuming two-point disease assessment. In trials where 3 C.cassicola isolates from different regions of Brazil were inoculated individually on 3 soybean cultivars contrasting in their resistance level we observed that the incubation period, disease severity, lesion density and lesion size at 14 days after inoculation, were influenced by the cultivar and not by isolate geographical origin. Using disease severity coupled with defoliation assessments throughout the reproductive growth stages, we performed correlations between grain yield and the leaf area injury at different plant positions - growth stages. The best correlation was observed with the assessments at R5.5 for injuries at middle canopy section.
A mancha alvo é uma doença foliar que pode ocasionar perdas de rendimento na cultura da soja. A doença tornou-se recentemente uma preocupação nos principais países produtores de soja (EUA, Brasil e Argentina), devido à crescente intensidade de suas epidemias. Os objetivos deste estudo foram: i) estimar a eficiência de controle da mancha alvo por fungicidas comerciais registrados no Brasil e a resposta em rendimento da soja, identificando fatores que afetam o desempenho dos fungicidas; ii) caracterizar a relação entre a severidade da mancha alvo e o rendimento da soja, utilizando técnicas meta-analíticas e identificar padrões que permitam compreender a heterogeneidade existente nessa relação; iii) explorar a variabilidade da resistência genética de cultivares de soja e verificar a metodologia mais eficiente para discriminar cultivares suscetíveis de resistentes; iv) explorar os efeitos da interação entre a origem do isolado de C. cassiicola e a cultivar de soja no desenvolvimento da epidemia; v) comparar a sensibilidade da posição do estrato do dossel afetado por C. cassiicola na redução do rendimento de grãos. Fungicidas compostos pelos ingredientes ativos fluxapyroxad + piraclostrobina foram os mais eficientes para controlar a mancha alvo, com níveis de controle de até 75%, e sua resposta ao rendimento dependeu da pressão da doença (PD, PDbaixa < 35% de severidade da mancha alvo na testemunha não tratada <= PDalta). Na PDbaixa, a aplicação de fungicidas não foi lucrativa, e em PDalta os fungicidas compostos por fluxapyroxad + piraclostrobina apresentaram os melhores desempenhos, superando o rendimento em relação à testemunha em 469 kg ha-1 (+ 19,1%). O rendimento potencial geral da soja, na ausência da mancha alvo, foi estimado em 3507 kg ha-1 para 41 ensaios distribuídos no Brasil. A redução no rendimento para cada ponto percentual de incremento na severidade da mancha alvo foi calculada em 0,48%. Com isso, níveis (hipotéticos) de severidade de mancha alvo de 50% ocasionariam uma redução de rendimento de 24% (variando entre 8% a 42%). A cultivar de soja teve um efeito significativo para explicar esta grande amplitude de respostas: reduções potenciais (com 50% de severidade) de 11%, 18,5% e 42% foram calculadas, respectivamente, para as cultivares BMX Potência RR, TMG803 e M9144RR. Foi constatada alta variabilidade na resistência genética no germoplasma testado, desde cultivares com intensidade de mancha alvo muito baixa (BRS360) até cultivares altamente suscetíveis. Avaliações da severidade da doença em uma única data não foi tão confiável quanto a avaliação integrada de duas ou três datas. Em experimentos onde 3 isolados de diferentes regiões do Brasil foram inoculados isoladamente em 3 cultivares contrastantes nos níveis de resistência, observou-se que o período de incubação, a severidade da doença, a densidade de lesões e o tamanho das lesões aos 14 dias após a inoculação foram influenciados pela cultivar. Porém, não foi observado efeito da origem geográfica do isolado de C. cassiicola nos componentes monocíclicos avaliados. A severidade da doença em diferentes posições da planta, juntamente com as avaliações de desfolha ao longo dos estádios de crescimento reprodutivo da soja, foi correlacionada ao rendimento de grãos. A melhor correlação entre o rendimento de grãos e a intensidade da doença (severidade + desfolha) foi observada nas avaliações em R5.5 na seção média do dossel.

Abstract:
A redução das perdas é de grande importância para estabilizar a oferta de alimentos ao longo da cadeia de suprimentos e fortalecer a segurança alimentar. O objetivo geral desta pesquisa foi realizar um diagnóstico detalhado sobre as perdas que ocorrem nas diversas atividades logísticas de soja e milho no Brasil, envolvendo a quantificação das perdas físicas, econômicas e ambientais acumuladas na cadeia de suprimentos de tais grãos e a identificação de estratégias e políticas públicas para mitiga-las, através da modelagem de programação matemática. Além disso, foi possível estruturar uma função de perdas na agrologística de grãos a partir de quatro variáveis: tipo de armazenagem, qualidade das vias rodoviárias, modalidade de transporte e canal de comercialização. As perdas totais na cadeia de suprimentos de soja e milho no ano de 2015 no Brasil atingiram o patamar de 2,381 milhões de toneladas, ou seja, algo em torno de 1,303% da produção, incorrendo em perdas econômicas decorrentes do custo de oportunidade com vendas perdidas e de gastos logísticos desnecessários na ordem de R$ 2,04 bilhões (US$ 610,78 milhões). Os cenários avaliados demonstram que a ampliação no uso da armazenagem dentro da fazenda, melhoria nas condições das rodovias brasileiras e das estradas que conectam as fazendas aos armazéns apresentam grande potencial para mitigação das perdas. Apesar da perda relativa de uma atividade logística assumir valor decimal, a perda acumulada ao longo da cadeia de suprimentos assume um valor global bastante considerável. Esse retrato enfatiza a necessidade de conscientização sobre as perdas visando fomentar políticas públicas e gestões eficientes para mitiga-las, dado as externalidades econômicas, ambientais e sociais geradas.
Reducing losses is of great importance in stabilizing the supply of food throughout the supply chain and strengthening food security. The general objective of this research was to perform a detailed diagnosis of the losses that occur in the many logistic activities of soybeans and maize in Brazil, involving the quantification of accumulated physical, economic and environmental losses in the supply chain of such grains and the identification of strategies and public policies to mitigate such losses through mathematical programming modeling. Besides, it was possible to structure a loss function of grains\' agrologistics in terms of four variables: type of storage, quality of roads, modality of transportation and marketing channel. Total losses in the soy and maize supply chain in 2015 in Brazil reached up to 2.381 million tons, or about 1.303% of production, incurring economic reductions due to the cost of loss (reduced sales and unnecessary logistical expenses for the handling of losses) in the order of R$ 2.04 billion (US$ 610.78 million). The evaluated scenarios show that the increase in the use of on-farm storage, the improvement in the conditions of the Brazilian highways and roads that connect the farms to the external warehouses present great potential to mitigate the losses. In spite the relative loss of a logistic activity takes on decimal value, the cumulative loss along the supply chain assumes a fairly considerable overall value. This reality emphasizes the need to raise awareness about losses in order to foster public policies and efficient management to mitigate them, given the created economic, environmental and social externalities.

Abstract:
O controle da ferrugem asiática é altamente dependente do tratamento com fungicidas. A decisão do momento correto da aplicação é fundamental para a eficiência do tratamento, visto que atrasos na efetuação do controle podem torná-lo tão ineficaz quanto à ausência de aplicações. O dano provocado pela ferrugem asiática é decorrente da redução da área foliar, devido à destruição do tecido vegetal e desfolha precoce. Tendo em vista a influência que o atraso no controle tem sobre a ferrugem asiática, e esta sobre a folhagem das plantas de soja, o dano pode ser melhor compreendido com o uso de variáveis que captem modificações na área foliar do hospedeiro. Com os objetivos de avaliar o efeito do atraso no controle da ferrugem asiática sobre o rendimento e os componentes do rendimento, a duração (HAD), a absorção da área foliar sadia (HAA) de plantas de soja e sobre a severidade da doença e examinar as relações entre o rendimento de soja com a duração, absorção da área foliar sadia e severidade da ferrugem asiática, foram conduzidos cinco experimentos no Centro de Pesquisa e Desenvolvimento Agrícola da Arysta LifeScience, em Pereiras-SP. Os experimentos envolveram um tratamento preventivo e tratamentos que corresponderam a atrasos crescentes na efetuação do controle químico. As relações entre os parâmetros citados acima foram avaliadas por meio de testes de comparação de médias (LSD) e regressões lineares e não lineares (p<=0,05). Os resultados mostraram que nas situações em que o início da ferrugem asiática da soja ocorre próximo à fase reprodutiva, o rendimento cai à taxa de -31 kg ha-1 a -15 kg ha-1 por cada dia de atraso no controle, sendo o dano maior nos estádios mais jovens e menor nos estádios mais avançados. Na relação entre o atraso no controle da ferrugem asiática da soja e HAA, 10 MJ m-2 deixam de ser absorvidos por cada dia de atraso no controle. Na relação entre o atraso no controle da ferrugem asiática da soja e HAD, a duração da área foliar sadia diminui 2,4 a 1,4 dias por cada dia em que o controle é atrasado. Na relação entre o rendimento de soja e HAA, são ganhos 2 kg ha-1 para cada MJ m-2 absorvido pela área foliar sadia. Na relação entre o rendimento de soja e HAD, são ganhos de 13 a 9 kg ha-1 para cada dia de duração da área foliar sadia. A relação entre atraso no controle da ferrugem asiática da soja e severidade da doença é de 0,25% ponto percentual para cada dia de atraso no controle. A relação entre o rendimento de soja e severidade da ferrugem asiática é de -36 kg ha-1 por cada ponto percentual de severidade. A variável que melhor se relaciona com o rendimento de soja é a absorção da área foliar sadia (HAA). Tanto HAA quanto HAD são variáveis melhores do que a severidade para serem usadas na quantificação de danos provocados pela ferrugem asiática na soja. Nas situações em que o início da doença ocorre próximo à fase reprodutiva, atrasos no controle da ferrugem asiática superiores a 28 dias apresentam o mesmo resultado que a ausência de controle. Não há redução no rendimento de soja se o início da ferrugem asiática ocorrer a partir do estádio R5.
The control of the asian soybean rust is highly dependent of fungicides treatment. The decision of the correct moment of application is critical for the efficiency of the treatment, since delays in the control can become it so inefficacious as the absence of applications. The damage caused by asian soybean rust is decurrent of the reduction of the leaf area, due to vegetal tissue destruction and early defoliation. In view, the influence that the control delay has on the asian rust, and this on the foliage of the soybean plants, the yield loss can be better understood with the use of variable that catch modifications in the leaf area of the host plant. With the objectives to evaluate the effect of the delay in the asian soybean control on the yield and the yield components, the duration (HAD) and absorption of the healthy leaf area (HAA) of soybean plants and on the disease severity, and to examine the relationship between the soybean yield with the healthy leaf area duration, healthy leaf area absorption and asian soybean rust severity, were conducted five field experiments in Agricultural Research and Development Center of the Arysta LifeScience, in Pereiras-SP. The experiments had involved a preventive treatment and treatments that had corresponded the increasing delays in the chemical control. The relationship between the cited parameters above had been evaluated by averages comparison test (LSD) and linear and non linear regressions (p<=0,05). The results had shown that in the situations where the beginning of the asian soybean rust occurs next to the reproductive phase, the yield fall -31 kg ha-1 to -15 kg ha-1 per each day of control delay, being the loss bigger in youngest stadiums and lesser in oldier stadiums. In the relationship between control delay of the asian soybean rust and HAA, 10MJ m-2 does not absorbed per each day of control delay. In the relationship of the control delay of the asian soybean rust and HAD, the duration of the healthy leaf area reduced 2,4 to 1,4 days per each day where the control is delayed. In the relationship between soybean yield and HAA, were obtained 2 kg ha-1 for each MJ m-2 absorbed by the healthy leaf area. In the relationship between soybean yield and HAD, were obtained 9 to 13 kg ha-1 for each day of healthy leaf area duration. The relationship between control delay of the asian soybean rust and disease severity was of 0,25% percentile point for each day of delay in the control. The relationship between soybean yield and severity of the asian soybean rust were of -36 kg ha-1 for each percentile point of severity. The variable that better becomes related with the yield soybean was the healthy leaf area absorption (HAA). Even HAA as HAD are better variables than severity to be used in the yield losses quantification of the asian soybean rust. In the situations that the beginning of the disease occurs next to reproductive phase, control delay of asian soybean rust higher than 28 days show the same result that the control absence. It does not have reduction in the soybean yield if the beginning of the asian soybean rust occurs after the R5 stadium.

This research aims to investigate and analyze, from the farmer perspective, the volume and factors that affect Western Paraná soybean harvest losses. The research problem is justified by the losses that occur even with the sector modernization. To results obtaining, primary data were collected through interviews applied to 243 farmers in 8 municipalities in the selected region. From these data, the treatment was carried out by two different analysis forms, at first a Descriptive Analysis, followed by the Principal Components Analysis, which corroborated literature appointments and results obtained at the descriptive analysis. The results pointed out that, despite sector development and modernization, there are still losses that can be controlled, mainly due to factors such as machinery operators specialization degree and climate unpredictability. Also, this research has detected a relationship change between farmers and cooperatives, that previously played a key role in the development of the agroindustrial sector, but which, from the farmer perspective, have lost their initial focus of aid and do not provide more active technical assistance at the proprieties in order to improve crop management. In addition, it was verified that losses related to field relief and topography are closely related to machinery modernization and its age. It is noted that, in order to improve this situation, special emphasis should be given to farmer specialization, aiming the usage of all technology and instruments available for agricultural sector at its full potential.
Esta pesquisa tem por objetivo investigar e analisar, sob a ótica do produtor rural, o volume e os fatores que afetam as perdas na colheita de grãos de soja na região Oeste do Paraná. A problemática da pesquisa se justifica nas perdas que ocorrem mesmo com a modernização do setor. Para a obtenção dos resultados, foram coletados dados primários, por meio de entrevistas com 243 produtores rurais em 8 municípios da região. A partir destes dados, foi realizado seu tratamento resultando em duas formas de análise, primeiramente descritiva e seguida de análise de componentes principais, que veio a corroborar resultados da literatura e aqueles obtidos na análise descritiva. Os resultados apontaram que, apesar do desenvolvimento e modernização do setor, ainda existem perdas passíveis de controle, isso se deve, sobretudo, a fatores como o grau de especialização dos operadores de maquinário e imprevisibilidade do clima. Notou-se também uma modificação na relação entre os produtores e as cooperativas, anteriormente com papel fundamental no desenvolvimento do setor agroindustrial, mas que, sob a ótica do produtor, estas organizações perderam seu foco inicial de auxiliá-lo e não prestam a assistência técnica mais ativa no campo a fim de melhorar o manejo da cultura. Ademais, pode-se verificar que as perdas relativas à relevo e à topografia da área estão intimamente relacionadas à modernização e idade do maquinário utilizado. Constata-se que, para a melhora desse quadro, faz-se necessário fomentar especialmente a especialização dos produtores, a fim de que se utilize todo o potencial da tecnologia e instrumental disponível para o setor agrícola.

Abstract:

Palmer amaranth is a growing concern in the United States. Previously thought to only be able to occupy the southern United States, this plant can now be found throughout the northern states as well. Infestations of Palmer amaranth can now be found in South Dakota and is raising many concerns. Palmer amaranth is characterized by large growth and can be highly competitive with many important crops. Soybean is an important crop in South Dakota, as well as the rest of the world, and has not escaped the detrimental aspects of an infestation of Palmer amaranth. The objectives of this study were to determine the possible impacts Palmer amaranth South Dakota.

Surveys were given to applicators and producers from many counties in South Dakota to gauge public awareness of Palmer amaranth and determine other possible infestations of Palmer amaranth. These surveys were made available at commercial applicator recertification classes throughout South Dakota and the Soy 100 meeting in Brookings, SD.

Growth rates and plant volume and biomass of Palmer amaranth from several seed source locations and local ascensions of common waterhemp and redroot pigweed were examined and compared in eastern South Dakota. Growth studies were conducted near Aurora, SD over two years using three planting dates from mid-May to late-June. Plant volume was measured every 10 to 20 days until harvest beginning in late-July. At harvest, plants were oven-dried and biomass was recorded.

Efficacy of several herbicide treatments were recorded on Palmer amaranth seedlings. Pre- and post-emergence treatments were conducted on Palmer amaranth planted in either sand or potting mix. Post-emergence treatments were applied at the three- to four-leaf stage. Visual ratings of plants were conducted 21 days after treatment.

Soybean yield loss due to Palmer amaranth was determined near Corsica, SD. Palmer amaranth in square meter plots were counted and harvested for biomass when soybeans reached R7 to R8. Plots containing two rows of soybeans were harvested several weeks later and yield loss was determined.

Survey results indicated that more needs to be done to provide information to the public based on respondents’ ability to correctly identify Palmer amaranth, common waterhemp, and redroot pigweed seedlings and mature plants. Several respondents also indicated possible infestations of Palmer amaranth. Not all counties in South Dakota were represented by the study.

Palmer amaranth had greater growth and biomass than either common waterhemp or redroot pigweed. Final volume of Palmer amaranth was greater at lower densities. Growth rates between sampling dates varied among planting dates, which resulted in similarities in final volume among planting dates. Common waterhemp and redroot pigweed shared similar plant volumes and biomass, however, plants in 2015 were larger, possibly due to climatic differences between years.

Herbicides tested that offered the best control of Palmer amaranth was a pre-emergence application of S-metolachlor and a post-emergence application of either dicamba or glufosinate. Glyphosate only provided partial control and mesotrione provided variable control. Atrazine had the little control as a pre- or post-emergence treatment. Thifensulfuron had no control of Palmer amaranth.

Soybean yield loss in 2016 determined an incremental loss of 9% at one Palmer amaranth m–2. Maximum yield loss of 45% was seen at 15 plants m–2, however, yield losses at densities slightly lower and higher caused a 35% maximum yield loss prediction. Yield loss in 2017 was variable due to outside factors and a relationship between yield loss and Palmer amaranth density or biomass could not be determined.

Abstract:
Agriculture is among the sectors strongly affected by climate changes (the largest damage in agriculture is usually caused by drought), which simultaneously influence the volume of production and safety of products. Besides, soybean is one of the most important crops used for human and animal nutrition, and certain branches of light industry. In climate conditions of Serbia, soybean is predominantly produced in the system of dry land farming. The chapter has several closely related goals. Primarily, it presents the detailed analysis of the economic importance of soybean production for the Republic of Serbia (with a special focus on sustainability of national food security). One of the goals is the assessment of cumulative losses incurred in the soybean production in the climatic conditions of the Republic of Serbia (dominantly caused by drought) in the last several years. Also, it was estimated the possible positive impact of irrigation on the current state of food security on the macro level, as well as the higher profitability of soybean production on the micro level.

Abstract:
Nitrogen is the key element of yield and the most limiting factor in achieving high yields. Nitrogen fertilization is specific because mineral nitrogen, the available form of nitrogen for the plant in the soil, is on one hand subject to leaching losses due to its mobility in the soil and denitrification, and on the other hand to the content increase due to mineralization of soil organic matter. To encourage more intensive adoption of atmospheric nitrogen in nitrogen-fixing, the presence of cobalt and molybdenum is necessary. Molybdenum is required for the binding of atmospheric nitrogen by Azotobacter and plays an important role in the fixation of N2. Legumes treated with molybdenum have a larger amount of fixed nitrogen. Cobalt is relevant to the process of biological fixation of molecular nitrogen. The role of cobalt in biological fixation of molecular nitrogen is specific, and it cannot be replaced in the process by other trace elements. Inoculation of soybean seed with microbiological fertilizer and seed treatment with cobalt and molybdenum, as well as the use of corn crop fertilization with different doses of nitrogen, has a different impact on the yield and properties of soybeans.

Abstract:
Soybean accounts for 38% of the total oilseed production in India, and around 50% of the total oilseed production in Kharif season. This crop has shown tremendous growth over the last four decades with an average national yield of 1264 kg/hectare. Currently, soybean is severely attacked by more than 10 major diseases. Yield losses due to different diseases ranges from 20 to 100%. Timely detection of soybean crop disease would help farmers save their money, effort, and crop from being destroyed. This chapter presents a case study on the development of a decision support system for prediction of soybean crop disease severity. The outcome of this system will aid farmers to decide the extent of disease treatment to be employed. Such predictions make use of human involvement, and thus are a source of ambiguities. To deal with such ambiguities in decision making, this decision support system uses fuzzy inference method based on triangular fuzzy sets.

Abstract:
The increasing world population over few decades has led to increase in demand of food grains or agricultural commodities, thus possessing great impact on food security. Conventional farming approaches has been traditionally practiced but a lot of effort is required to make to enhance agricultural production. With changing climatic conditions plants are vulnerable to several stress factors. In order to combat such conditions, the agricultural systems are needed to be contemporary with advance and recent technologies. Crops after harvest are liable to a lot of changes which ultimately affect quality and quantity of produce, thus reducing economic value. Postharvest losses are decisive factors in reducing loss of produce and agricultural commodities. Thus in order to achieve maximum production, it is therefore essential to reduce postharvest losses and ensures proper management of postharvest products. Postharvest physiology is the science which deals with quantitative and qualitative study of physiology of agricultural products after harvesting. Biotechnological and transgenic approaches are the recent and emerging technologies that possess great impact on agricultural production. Transgenic technology like genome editing, CRISPR/Cas9, TILLING are successfully used in various species to enhance production, possess resistance to abiotic and biotic stresses, enhance shelf life and improve nutritional quality. Transgenic crops or Genetically modified crops (GMO) like tomato, brinjal, soybean, cassava etc are cultivated globally. These techniques therefore are promising means in establishing food security, increasing crop production, reducing postharvest losses, production of secondary metabolites, hormones and plantibodies.

Abstract:
Soybean (Glycine max L. Merr) is the most important legume and threaten by diverse pests and diseases. Complex interactions among rhizosphere organisms are found in all agro-ecosystems. Results of these interactions can be positive and/or negative in terms of plant production. Soil nematode community consists of different trophic groups of nematodes. Nematodes are the most abundant soil invertebrates. Several nematode species penetrate soybean roots as parasites, and can cause loss in yields. Arbuscular mycorrhiza fungi are obligate plant symbionts that colonize soybean roots naturally. The aim of the study was to evaluate effects of irrigation and amendments of bioproducts containing beneficial soil microorganisms (ABM) on nematode community and mycorrhizal root colonization in soybean. Field experiments were conducted in soybean in 2013 in Osijek, Croatia. The plots were either rain fed or irrigated to 60-100% field water capacity (FWC). We tested soil amendments and soil + foliar amendments of three commercial products containing beneficial organisms. Average number of nematodes per soil sample varied from 186,67 (soil ABM in non-irrigated plots) to 297,57 (soil+foliar ABM in plots with 60-100% FWC), and there were no significant differences between the treatments. Bacterial feeding nematodes were the most abundant, while plant parasitic genus Pratylenchus was the most abundant among other plant parasitic nematodes. There was no clear influence of any of the treatments on soil nematode community. Amendments of the bioproducts increased mycorrhizal root colonization in rain fed plots, while it decreased the mycorrhizal root colonization when soybeans were irrigated. Irrigation increased mycorrhizal root colonization in plots without amendments of the bioproducts, and mycorrhizal colonization differed significantly between the sampling dates. Further research is needed to determine if irrigation alters the potential of mycorrhiza to colonize the roots.

Abstract:
Brazil is a large producer and exporter of crops in global terms. Weeds may be responsible for ~14% of crop losses, depending on the crop system. Herbicides occupy 58% of the Brazilian pesticide market; however, the continuous use of these products and the high selection pressure have led to the emergence of weeds resistant to herbicides. Today, there are 51 weed species reported as being resistant to herbicides in Brazil, of which 17 involves cross and multiple-resistance. Acetolactate synthase (ALS), acetyl coenzyme A carboxylase (ACCase) and 5-enolpiruvylshikimate-3-phosphate synthase (EPSPs) inhibitors are the herbicidal groups with the most resistance cases. Soybean, corn, rice, wheat and cotton present 30, 12, 10, 9 and 8 cases, respectively, occurring mainly in herbicide-resistant crop fields from the Southern and Central West regions of the country. To better understand the dimensions of herbicide resistance, in this chapter, we will explore the size of agricultural activity in Brazil, the pesticide market and the use of herbicides in the main crops. In addition, the agronomic, scientific-technical and economic aspects that have contributed, directly or indirectly, to the selection of resistant weeds will be discussed in order to have an overview of the economic impact of herbicide resistance management.

Abstract:
The Sclerotinia sclerotiorum is a phytopathogenic fungus that causes the White Mold of soybean, being responsible for losses of up to 100% in agricultural production. The objective of this work was to verify and analyze the effect of the raw aqueous extract (EBA) of ginger Zingiber officinalis on a strain of Sclerotinia Sclerotiorum isolated from soybean, cultivated and maintained in vitro in laboratory. The methodology consisted of a longitudinal study of the statistical analysis of the mycelial growth velocity index (MICV), after treatment of the mycelia with different concentrations of aqueous crude extract. The results showed a direct relationship between increasing concentration of EBA and a significant negative effect on the growth of scleroderia. It was possible to conclude that the antifungal activity of ginger EBA was able to inhibit the in vitro growth of Sclerotinia sclerotiorum, with potential protection of soybean crops; it can become a sustainable alternative in the control of this fungus, by decreasing the use of agrochemicals that cause damage to public health and environmental damage.

Abstract:
The agribusiness represents a significant portion of the global economy. In Brazil, agribusiness has a significant share of the country’s economy and represented 21.6% of GDP in 2017. To increase productivity, proper management of a crop, including pest control, is of vital importance. Annually, plant pests cause losses of 20% to 40% of production. For this reason, it is important to monitor the level of defoliation to take preventive actions. Therefore, in this work an automatic methodology is proposed using Convolutional Neural Networks, to detect the level of defoliation from leaf images in the soybean crop. In addition to detecting the presence of defoliation, the proposed methodology also provides the affected regions of the leaf through the segmentation of the image. Experimental results showed 83% accuracy using the proposed methodology versus 60% of SegNet CNN. The results are promising considering that the images were captured in the field, which presents challenges such as lighting, stages of development, scale, among others.

The purpose of our study was to develop biological methods to protect soybean from pests. Lepidoptera is believed to be one of the most numerous groups of insects in this crop. As a conservative estimate, 20 species of Lepidoptera were found in soybean agrocenosis; the greatest damage to Glycine max L. caused Etiella zinkinella Tr. 1832 and Helicoverpa armigera Hb. 1805. It was shown that not less than 500 m distance of crops from the main reserve of pests – robinia and the use of early ripening varieties provided the minimum loss of bean yield (no more than 0.9 – 1.9%). The use of biological preparations based on B. thuringiensis – lepidocide and bitoxybacillin allowed reducing beans and seeds damage by pests by 20-30%.
