RESUMO: Com o objetivo de analisar e discriminar métodos de avaliação do perfil mobilizado do solo através de perfilômetro de barra corrediça, realizou-se um trabalho em campo, sob latossolo vermelho-amarelo distrófico (LVAd), montado no esquema de parcelas subdivididas no espaço. Procedeu-se em delineamento inteiramente ao acaso, com quatro repetições. As parcelas constaram do preparo primário do solo, aração e gradagem, e as subparcelas de dois perfilômetros de barra: 1000 mm (Perf 1) e 2500 mm (Perf 2) de comprimento. Avaliou-se a área mobilizada do solo e a área de elevação, referenciando-se a superfície natural do solo em pré-preparo, a espessura média da camada mobilizada, o empolamento do solo, o índice de rugosidade antes e após o preparo e a modificação da rugosidade. Observou-se diferença entre os aparelhos para todas variáveis. Ocorreu maior expressividade dos dados com o Perf 2 para os tipos de preparo avaliados. Os dados obtidos pelo Perf 1 subestimaram ou superestimaram os valores das variáveis analisadas. Concluiu-se que, para as condições estudadas, indica-se a tomada de 200 pontos por parcela, quando utilizado perfilômetro de barra corrediça de 2500 mm de comprimento, para estudo do perfil do solo e determinação de parâmetros relacionados a essa característica. Palavras-chave: mobilização do solo, área de elevação, área mobilizada, empolamento. MICRORELIEF METER: EVALUATION OF METHODOLOGY FOR ANALYSIS OF ROUGHNESS OF SOIL ABSTRACT: The aim of this study is analyzing and discriminating methods of soil mobilized profile evaluation through a sliding bar profilometer. A field work was carried out under distrofic red-yellow latosolo (LVAd), observed in plots subdivided in space. A completely randomized design was used with four repetitions. The plots consisted of the primary soil preparation, plowing and harrowing, and the subplots of two bar profilometers: 1000 mm (Perf 1) and 2500 mm (Perf 2) in length. The soil mobilization and lifting area were evaluated, with reference to the natural surface of the pre-tillage soil, average thickness of the mobilized layer, soil puffiness, roughness index before and after the preparation, and roughness modification. It was observed a difference between the devices for all variables. There were higher data with Perf 2 for the types of preparation evaluated. The data obtained by Perf 1 underestimated or overestimated the values of analyzed variables. It was concluded that for these studied conditions, it is indicated the taking of 200 points per plot, when using a 2500 mm long slide bar profilometer, to study the soil profile and to determine parameters related to this characteristic. Keywords: soil mobilization, lifting area, mobilized area, blistering.

ABSTRACT Competition is the best known form of direct interference of weeds on agricultural crops. However, there is relatively little information on the competition of the weed sudangrass on soybean, which has been common in agricultural areas in the southern of Rio Grande do Sul. The objective of this study was to evaluate the competition between sudangrass and soybeans using replacement series experiments. The experiment was carried out in a greenhouse in a completely randomized design with four replications. The treatments consisted of soybean and sudangrass associations. The experimental units were 8-L plastic pots, in the proportions 0: 8, 2: 6, 4: 4, 6: 2, 8: 0, corresponding to 0, 25, 50, 75 and 100% of the crop and weed respectively. Shoot, root and total dry matter and plant height were analyzed through diagrams applied to replacement series and competitive indices. Soybean showed competitive superiority in coexistence with sudangrass in relation to shoot, root and total dry matter. The intraspecific competition was more significant for the crop and inter-specific competition was more important for the weed.

Uma conseqüência é a obstrução que reduz a uniformidade de emissão. Assim, os objetivos deste trabalho foram estudar o efeito da qualidade da água sobre o desenvolvimento de obstruções, bem como testar a eficiência de dois tipos de ácidos no controle dessas obstruções. O experimento foi instalado no delineamento inteiramente aleatorizado, no esquema fatorial 4x2 com duas repetições. Os tratamentos foram quatro tipos de água e dois ácidos (nítrico e clorídrico). Foi feita uma avaliação do sistema antes e outra após a acidificação. Para cada tratamento foram calculados a vazão, o coeficiente de variação de fabricação e a uniformidade de emissão. A qualidade da água de irrigação não influenciou a vazão, o coeficiente de variação de fabricação e a uniformidade de emissão. O uso de ácido nítrico e clorídrico foi eficiente no controle de obstruções. O uso do ácido clorídrico fica limitado a águas com menores teores de bicarbonatos.

No entanto, a agroindústria processadora de polpa de frutas gera diversos resíduos, como cascas, talos e sementes, que muitas vezes são desperdiçados, mas podem ser utilizados como ingredientes para o desenvolvimento de novos produtos alimentícios. Diante do exposto, objetivou-se com este trabalho avaliar a cinética de secagem e a qualidade físico-química dos resíduos da agroindústria processadora de polpa de frutas. Com isso, determinou-se a cinética de secagem de cinco resíduos agroindustriais (manga, abacaxi, acerola, goiaba e graviola), os quais foram submetidos as análises físico-químicas (umidade, extrato seco, cinzas, acidez total titulável, pH e atividade de água) antes e após a secagem em estufa com circulação forçada de ar, a 60 °C. Os resultados obtidos foram tratados, através de Delineamento Inteiramente Casualizado em esquema fatorial, aplicando Análise de Variância e comparação de médias pelo teste de Tukey a 5% de significância. Observou-se bons ajustes (R2>0,98) na cinética de secagem. Após a secagem, a maioria dos resíduos apresentaram redução nos parâmetros físico-químicos de umidade, atividade de água e pH, bem como aumento do extrato seco, cinzas e acidez total. Infere-se que o resíduo de graviola e goiaba indicaram melhores respostas às condições experimentais empregadas, requerendo ainda o estudo da variação de temperatura de secagem e avaliação da estabilidade física, química e microbiológica. Palavras-chaves: desidratação, farinhas vegetais, qualidade físico-química KINETICS OF DRYING WASTE FROM FRUIT PULP PROCESSING AGROINDUSTRY ABSTRACT: The fruits pulp processing industry generates wastes as barks, stalks and seeds, which are often wasted, but can be used as ingredients for development of new food productsThe aim of this work was to evaluate the drying kinetics and the physicochemical quality of residues from the fruits pulp processing industry. The drying kinetics of five agroindustrial residues (mango, pineapple, acerola, guava and graviola) were determined, which were submitted to physical-chemical analyzes (moisture, dry extract, ash, total acidity, pH and activity of water) before and after oven drying with forced air circulation at 60°C. The results were evaluated using a completely randomized design in a factorial scheme, applying Analysis of Variance (ANOVA) and comparison of means by the Tukey test at 5% of significance. Good adjustments (R2>0.98) were observed for drying kinetics. After drying, most of the residues showed a reduction in the physical-chemical parameters of moisture, water activity and pH, as well as increase of dry extract, ashes and total acidity. It is inferred that graviola and guava residue indicated better responses to experimental imposed conditions, also requiring the rying temperature variation study and physical evaluation, chemical and microbiological stability.

Traditional medicine is one of the drugs used by the community to be one of the efforts to treat diseases. One of them is Diabetes Mellitus (DM). DM is a metabolic disease characterized by hyperglycemia which results in an increase in free radicals in the cell. DM treatment is quite expensive so an alternative drug is needed. One of them is Tithonia diversifolia A. Gray. This study used a completely randomized design, consisting of 1 control, 4 treatments (P1: Only alloxan induced), P2: Alloxan 65 mg / kg BB, P3: Metformin 65 mg / kg BB, P4: Boiled leaves of moon leaves 24.6 mg / 10 ml and P4: Moon flower leaves boiled water 49.1 mg / 10 ml. The parameters observed were blood sugar in male mice and the number of cells in the islands of Langerhans before and after being given boiled leaves of moon flowers and metformin. Data were analyzed using ANOVA then continued with DMRT test with a significant difference of 5%. The results showed that administration of boiled kembang bulan leaves and metformin for 7 days could reduce blood sugar levels in mice and accelerate the regeneration of pancreatic cells. The most significant impact is the treatment with the highest dose, namely P4 (Moon leaf leaves boiled water 49.1 mg / 10 ml).

ABSTRACT Salinity is one of the problems that limit plant development, with the germination, growth, and initial establishment stages being the most sensitive to saline stress. Erythrina velutina, popularly known as “mulungu” in Brazil, is a species native to the Caatinga biome, which grows in conditions of soil rich in salts. The damage caused by salinity to the quality of its seeds and the use of techniques that mitigate such effects are little known. Thus, this work aimed to evaluate salicylic acid as a mitigator of saline stress in the physiological quality of mulungu seeds. The quality of two seed lots from two Brazilian states (L1: Mossoró, Rio Grande do Norte, and L2: Pentencostes, Ceará) was evaluated. A completely randomized design in a 2 (seed soaking with salicylic acid (SA) - distilled water and 1.0 mM SA) × 4 (electrical conductivity of irrigation water - ECw - 0.0, 3.0, 6.0 and 9.0 dS m-1) factorial scheme with four replications of 50 seeds each was used. Saline stress reduces the quality of mulungu seeds and seedlings. SA increases the vigor of the seeds, promoting improvements in germination under saline conditions.

Abstract: Fungi are considered as the most important among pathogens due to the higher number of species and to the damage caused both in yield and in seed quality. Thus, aimed to verify the effect of fungicide and insecticide treatment on sanitary quality and physiological performance of soybean seeds before and after storage. Seeds from cultivars NS 7494, NS 8693 and NS 7338 IPRO were used, which were analyzed separately by a completely randomized design in a 3 x 6 factorial design, being three chemical treatment applications: 1) treated and evaluated; 2) treated, stored and evaluated; 3) stored, treated and evaluated; and six mixtures of fungicides and insecticides: (Imidacloprido + Tiocarbe) + (Carbendazim + Tiram), (Imidacloprido + Tiocarbe) + (Metalaxil-M + Fludioxonil), Thiamethoxam + (Carbendazim + Tiram), Thiamethoxam + (Metalaxil-M + Fludioxonil), (Fipronil + Piraclostrobina + Metil-tiofanato) and the control, which was added only water. The healthy test, germination, cold and accelerated aging tests were evaluated. Seed treatment products require at least two months to be effective in controlling Penicillium spp. and Fusarium spp. The mixtures containing Carbendazim + Tiram in its composition are efficient in the control of pathogens regardless of the application time of products.
