Agriculture is an activity of great expansion in the state of Mato Grosso (MT), which reflects on the city of Sinop and proximities, and in an intense way mechanization is intensively applied in these areas. This study aimed to diagnose the level of mechanization (Kw/ha) in relation to the cultivated agricultural area and the total area. To this, a sample of 15 agricultural properties located in the region of Sinop – MT were analyzed. For the scale representation of the properties, 4 strata were applied in function of the property total agricultural area. The availability of power in the property resulted in significant differences in the mechanization index. Stratification was efficient for the determination of the mechanization index in the strata, occurring similarities only between strata 2 (3001 – 5000 ha) and 3 (5001 – 9000 ha). The average participation of the areas analyzed was approximately 50%, in which bigger areas presented inferior participation than smaller areas.

This study aimed to evaluate the potential of essential oils of rosemary (Rosmarinus officinalis), baccharis (Baccharis trimera), lemon grass (Cymbopogon citratus), basil (Ocimum basilicum) and eucalyptus (Corymbia citriodora) in inducing resistance in cotton plants against C. gossypii var. cephalosporioides. The inductive effect of the essential oils was evaluated in plants growing in pots in the environment, which were treated with 1% essential oil at 47 days of age. 24 hours after elicitor treatment the plants were inoculated with a suspension of 1.5 x 105 conidia mL-1 of C. gossypii var. cephalosporioides. Five evaluations were performed disease and calculated the area under the disease progress curve. All essential oils showed potential for inducing resistance against cotton C. gossypii var. cephalosporioides.

RR soy was designed to reduce costs and favour weed management using only one type of herbicide, the glyphosate. Although, there are just some few studies that actually evaluates the effect of this product on the physiology and final production of soybeans in northern Mato Grosso. The aim of this work was to verify the effects of the herbicide glyphosate molecule, on vegetative characteristics and productivity in transgenic soybean. The experiment was conducted at the Farm Água Viva, Sinop-MT. The experimental design was a randomized block design with five replications, with five treatments, three glyphosate concentrations (480 g ia.ha-1, 960 g ia.ha-1, 1920 g ia.ha-1) another treatment with mechanical control (hoe) and the control (no weed control). Was evaluated the following variables: phytotoxicity, plant height, chlorophyll content, fresh weight, dry weight and productivity. As for efficient control by glyphosate application at doses of 960 g ia.ha-1 and 1920 g ia.ha-1 significantly reduced weed populations up to 21 DAP. Phytotoxicity was found near the time of application, especially at the maximum concentration applied. The effect of the herbicide on the variable plant height was more pronounced at 21 DAA and the recommended concentration (960 g ia.ha-1) did not differentiate using the hoe. For fresh pasta, this was reduced with the application of herbicide and dry weight was not different between treatments. Productivity was higher in treatments with hoe, minimum and medium concentrations of glyphosate herbicide. The maximum concentration of the herbicide damaged the productivity as well as treatment unchecked, the less productive. For chlorophyll values glyphosate application promoted a significant reduction, which can be explained by the decrease in manganese uptake by the plant.

In foods, the flavor and aroma are very important attributes, thus the main objective of this study was to identify the volatile compounds (VC) of the "BRS-366 Jaburú" acerola variety, for which we used the solid phase microextraction method (SPE). The separation and identification of volatile compounds was made using gas chromatography-mass spectrometry (GC-MS). Three fibers were evaluated, Polydimethylsiloxane / Divinylbenzene (PDMS / DVB), 65 micrometres Divinylbenzene / Carboxen / Polydimethylsiloxane (DVB / CAR / PDMS) 50/30 m and polyacrylate (PA) 85 uM to compare the extraction of its components. Thirty-three volatile compounds were identified and classified into eight chemical classes: carboxylic acids, alcohols, aldehydes, ketones, esters, hydrocarbons, phenylpropanoids and terpenoids. The peak areas of each of the extracted compounds were expressed as percentages to indicate the relative concentration of each, of which ethyl acetate is distinguished by being responsible for the fruity aroma notes. Thus, the fiber PDMS / DVB was the best as it enabled to extract a greater amount of volatile compounds

This study aimed to determine the plasma levels of urea and creatinine, besides evaluating the influence of sex and age factors on these substances in Pantaneiros horses, animals of high economic and social importance in the Pantanal. In Poconé-MT region, 80 animals were used, which were divided into four groups: Group 1: male foals (n= 20), aged 8 months and 2 years, Group 2: female foals (n= 20), aged 8 months and 2 years, Group 3: adult males (n= 20), aged from 3 years, Group 4: adult females (n= 20), aged from 3 years. All animals were classified as healthy after clinical examinations, as well as serum negativity for Equine Infectious Anemia (EIA). Blood samples for subsequent laboratory analysis were taken from the jugular vein. The mean values of urea and creatinine found for Pantaneiros horses were similar to other breeds of horses and did not vary influenced by the sexual factor, however plasma levels of creatinine increased with the age.

 A domestic chinchilla Chinchilla lanígera) came to death at the Veterinary Hospital of University of Santo Amaro and was referred to Patology Animal service, which conducted the necropsy and was visualized adrenal bilateral hyperplasia. On histopathologic examination, it was found metaplasia of fat cells.Â

Tracheobronchial secretion was collected by endoscopy (Welch-AllynÒ, 200cm long and 9mm diameter), from equines with different ages, races and sex, for posterior cytological analysis. Thirty-six equines were divided into two groups (Group I = stabled, n = 18; Group II = field regimen, n = 18). Animals of Group I (age = 3.5 years) were lodged in the Tarumã´s Jockey Club in Curitiba, Parana State. The equines of Group II always were maintained at field condition (never were stabled), in the farm located in Jacarezinho, Paraná State. Following endoscopic exams, tracheobronchial secretion smears were stained by Pappenhein´s method and submitted to cytological analysis. Group I had higher frequency of tracheal discharge than Group II. The cytological analysis showed more presence of macrophages (58.8%), foamy cells (2.3%), body giant cells (0.2%), neutrophils (4.57%), eosinophils (0.7%) and Curshmann´s spirals (0.04%) on 3 of the 18 animals. The cytological analysis of Group II showed higher frequency of ciliated epithelial cells than Group I, and no Curshmann´s spirals were observed. In conclusion, data showed that horses stabled had more cytological alterations than the animals maintained at field, therefore more tracheobronchial complications. Thus, the care of place where horse are stabled have influence on development of respiratory diseases, may predispose to affections as Chronic Obstructive Pulmonary Disease and Exercise-Induced Pulmonary Hemorrhage, as well athletic horses may be never reach their full respiratory potential.

The present study aimed to establish the protocols for disinfestations, germination and in vitro micropropagation of grápia (Apuleia leiocarpa (Vogel) Macbride). To disinfestations and break seed dormancy, were tested three treatments, and inoculated into test tubes containing growing medium. As for variable germination were tested four medium of nutritious, MS, MS½, WPM, WPM ½. And, to introduce organogenesis, the growing medium used was WPM, supplemented with BAP, at concentrations of 0,0; 0,4; 0,8 ml/L, combined with ANA in the concentration of 0,05 ml/L. The explants used in this study were hypocotyls and cotyledons obtained from grapia seedling germinated in vitro, 30 days after inoculation in growing medium. The organogenesis induction was performed in WPM growing culture. The evaluated parameters in this study were the disinfestation and break dormancy, germination and organogenesis induction. The data were subjected to variance analysis and the by Tukey test, at 95% of probability. Treatment III showed to be more efficient for both aseptic and to break seed dormancy, providing 92% of germination and 2% of contamination. As for the in vitro germination, the WPM and WPM½ growing cultures were the most effective, favoring 100% of germination. For various formations of calluses and sprouts on hypocotyls explants, there was no significant difference between the tested BAP concentrations. However, it was observed in cotyledon explants that the best results occurred at concentrations of 0,8 ml and 0,4 ml of BAP and 0,05 ml of ANA.Â

This study aimed to evaluate the influence of different cultures second crop on the population of the nematode P. brachyurus, and the soybean crop productivity. The experiment was conducted at Embrapaagrosilvopastoral during agricultural year 2012/13, 2013/2014 and 2014/15, 0.4 ha of tracks. During the 2012/2013 crop soybeans planted in every area, in the off-season in 2013, two corn cultivars, two soybean and corn consortium with B. ruziziensis in 2013/14 crop was sown soybeans again in the off-season 2014 They were sown three soybean cultivars, a cultivar of corn and intercropping of millet with C. ochroleuca. In the season 2014/15 soybean was sown in every area and in the off-season 2 cultivars of maize and 3 soybean cultivars. Productivity was determined and the population of the P. brachyurus in roots. It was observed that millet consortium and C. ochroleuca were efficient in controlling the nematode. There were differences of reactions not only among species but within species and between the genotypes and soybeans, interfering with the population of the P. brachyurus. In the season 2013/2014 the soybean yield was influenced by the treatments, but the harvest 2014/2015 there was no statistical difference.

This study aimed to evaluate the effect of forms of application of foliar fertilizers and fungicides to control fungus causing white maize spot, Phaeosphaeria maydis, and the growth and development of hybrids maize. The design had randomized blocks, with the use two sources hybrids maize with different reaction to white maize spot: resistant and susceptive and application with moisture of foliar chemical fungicide + cobalt foliar + molybdenum foliar + manganese and control treatment, without application consisting of four treatments and five replications. In the treatments with application of moisture were done on vegetative maize growth stage V8 (stage that determine that the number of kernel rows), VT (stage that arrives when the last branch of the tassel is completely visible) and reproductive maize growth stage R2 (kernels are white on the outside and resemble a blister). The evaluation of variables of growth of maize plants: grain dry mass, cob dry mass, leaf dry mass, culm dry mass and modificated leaf ear and total plant dry mass. Harvest was carried out when the grains were 20% humidity. The application of fungicides and foliar fertilizers increased the leaves, culm, ear modificated, cobs and shoot dry mass plants maize. The application of fungicides and foliar fertilizers providing returning of 11.409,5 kg ha-1 of shoot dry mass plants with increased of 1.296 kg ha-1 on soil(12,81%). In the susceptive hybrid maize the application of fungicides and foliar fertilizers provide higher dry mass grains and shoot of plants.
