A soja (Glycine max L.) é principal cultura do agronegócio brasileiro e tornou-se a mais expressiva economicamente no país, tanto pelo aumento da área cultivada quanto pelas novas tecnologias disponibilizadas aos produtores. As doenças podem ter origens fúngicas, bacterianas e viróticas e neste estudo destaca-se a murcha-de-Curtobacterium, causada pela bactéria gram-positiva Curtobacterium flaccumfaciens pv. flaccumfaciens. O sintoma é caracterizado por uma mancha bacteriana marrom nas folhas de soja. O objetivo do trabalho foi expor os aspectos do patógeno C. flaccumfaciens pv. flaccumfaciens na cultura da soja, discutindo as principais estratégias de controle para minimizar os problemas com a doença. Deve-se ressaltar que, ao obter conhecimento sobre os aspectos agronômicos e os fatores limitantes da cultura da soja em relação à bactéria e seus principais aspectos biológicos, será possível a adoção das melhores técnicas de manejo da doença. Conclui-se que a busca por cultivares resistentes é de extrema importância no manejo da doença, uma vez que outros métodos de controle são pouco eficientes. Para alcançar o controle da mancha bacteriana marrom na cultura da soja é necessário a adoção conjunta de todas as técnicas de controle empregadas de forma unificada (manejo integrado da doença) visando a manutenção da população de C. flaccumfaciens pv. flaccumfaciens em baixos níveis.   Palavras-chave: Mancha Bacteriana Marrom. Controle de Doenças. Glycine max L. Distribuição.   Abstract Soybean (Glycine max L.), is the main crop of Brazilian agribusiness, it has become the most economically important in the country, both due to the increase in cultivated area and the new technologies available to farmers. Diseases can have several origins, including fungal, bacterial and virotic, but in this study, we will talk about curtobacterium wilt, caused by a gram-positive bacterium Curtobacterium flaccumfaciens pv. flaccumfaciens, responsible for brown bacterial wilt on soybean plants. The objective of this work was to expose the aspects of the pathogen Curtobacterium flaccumfaciens pv. flaccumfaciens in soybean crops, discussing the main control strategies to minimize problems caused by this disease. It should be emphasized that gaining knowledge about the agronomic aspects and limiting factors of soybean crop in relation to the pathogen is necessary to reach the best management of the disease. We concluded that the search for resistant cultivars is extremely important for disease management, since other control methods are inefficient. To achieve the control of bacterial tan spot in soybean crop, it is necessary to joint adoption of all the control techniques used in a unified way (disease integrated management) aiming at maintaining the population of Curtobacterium flaccumfaciens pv. flaccumfaciens at low levels.   Keywords: Bacterial Tan Spot.

Visou-se quantificar teórica e experimentalmente os níveis residuais de Endosulfan e seus principais metabólitos em óleo de soja e avaliar a confiabilidade dos valores teóricos em relação ao experimental. A soja foi cultivada no campo nos sistemas manejo integrado de pragas (MIP) e convencional. Extraiu-se o óleo de soja utilizando o solvente hexano em extrator Soxhlet. Determinaram-se as concentrações do Endosulfan no grão e no óleo, mediante cromatografia em fase gasosa, com detector de captura de elétrons (Ni63). A concentração de Endosulfan no óleo foi obtida teoricamente multiplicando-se a relação entre a massa grão/óleo pela concentração deste inseticida encontrada experimentalmente no grão. A relação percentual da concentração de Endosulfan no óleo, entre os valores teórico/experimental, enquadraram-se na faixa de 94% a 114% e 81% a 92%, respectivamente, para os sistemas MIP e convencional. Como a média geral dos níveis de Endosulfan, calculada teoricamente, alcançou 94% do valor obtido experimentalmente concluiu-se que o cálculo teórico pode ser utilizado para determinar os níveis deste inseticida no óleo de soja. EVALUATION OF THE THEORETICAL AND EXPERIMENTAL RESIDUAL LEVELS OF ENDOSULFAN IN SOYBEAN (Glycine max. (L) Merrill ) OIL Abstract The objective of this study was to quantify theoretically and experimentally the residual levels of Endosulfan and main metabolites in soybean oil and to evaluate the reliability of the theoretical values in relation to the experimental values. The soybean was grown in the fields in the pest integrated management (PIM) and conventional systems. The soybean oil was extracted by using hexane as solvent in Soxhlet extractor. The Endosulfan concentrations were determined in the grains and oil by means of gas chromatography equipped with electron capture detector (Ni63). The Endosulfan concentration in soybean oil was theoretically obtained by multiplying the relationship between the grain mass/ soybean oil by this insecticide concentration determined experimentally in the grain. The percents relationship of the concentration of Endosulfan in the soybean oil between the theoretical/experimental values were in the range of 94% to 119% and 81% to 92%, respectively, for the PIM and conventional system. As the general average levels of Endosulfan, theoretically calculated, reached 94% of the value obtained experimentally it was concluded that the theoretical calculation could be used for determination this insecticide levels in the soybean oil.

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.

Penelitian tentang pengaruh pemberian Pupuk organik cair (POC) asal limbah tumbuhan terhadap serapan hara N dan P serta produksi tanaman kedelai (Glycine max (L) Merrill) di lahan gambut telah dilaksanakan di kampus II Unisi Fakultas Pertanian Jl. Lintas Propinsi Parit 01, Desa Pulau Palas, Kecamatan Tembilahan Hulu, Kabupaten Indragiri Hilir Propinsi Riau. Dimulai dari bulan Agustus sampai bulan Oktober 2013. Tujuan dari penelitian ini untuk mendapatkan POC asal limbah tumbuhan yang terbaik untuk serapan hara N dan P serta produksi tanaman kedelai di lahan gambut. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktor tunggal dengan 7 perlakuan dan 4 ulangan, 2 tanaman dijadikan sampel. Perlakuan dosis POC limbah tanaman pisang dan POC limbah sayur kol yang diberikan yaitu 0 L/Ha, 200 L/Ha, 400 L/Ha dan 600 L/Ha. Parameter pengamatan yaitu : serapan hara N dan P pada fase awal generatif, tinggi tanaman, jumlah bintil akar, polong hampa, produksi perplot, berat 100 biji dan brangkasan kering. Data pengamatan dianalisis dengan sidik ragam (ANOVA) dan dilanjutkan dengan Uji Lanjut Tukey HSD pada taraf 5%. Berdasarkan penelitian yang telah dilaksanakan dapat disimpulkan bahwa pemberian POC asal limbah tumbuhan tidak berpengaruh nyata terhadap serapan hara N dan P, tinggi tanaman, jumlah bintil akar, polong hampa, brangkasan kering tetapi berpengaruh nyata terhadap produksi perplot dan berat 100 biji.

Heavy metals are one of the most important pollutants released to the aquatic environment by the various industrial activities. The use of these wastewater for irrigation results accumulation of heavy metals in soil and plants. So, the present investigation deals with the various concentrations (0, 5, 10, 25, 50, 100, 200 and 300 mg/l) of copper and zinc on germination studies of soybean. The different concentrations of copper and zinc were used for germination studies. The seedlings were allowed to grow upto seven days. The studied morphological traits increased at 5 mg/l concentration and these parameters are gradually decreased with the increase of copper and zinc concentrations.
