title: Spectral detection of nematodes in soybean at flowering growth stage using unmanned aerial vehicles

description: ABSTRACT: Soybean is one of the main crop species grown in the world. However, there is a decline in productivity due to the various types of stress, including the nematodes Heterodera glycines and Pratylenchus brachyurus. The objectives were to determine the best spectral band for detecting H. glycines and P. brachyurus at the beginning of flowering (R1). Soil and root sampling was conducted at nine sampling sites in each of the five nematode-infested regions, totaling 45 sampling points. Flights were made at all regions using Phantom 4 Advanced, Sequoia and 14-band customized Sentera. For H. glycines, the red spectral band best explained the variability on soil and root nematode counts as well as the second stage of juveniles in soil. For P. brachyurus, Sentera RedEdge best explained the variability in root nematode counts and Sequoia NIR best explained soil juveniles. A multiple linear regression model using spectral data for detecting P. brachyurus and H. glycines improved R² compared to simple linear regressions. At flowering growth stage (R1), soybean spectral reflectance was associated with the number of H. glycines and P. brachyurus on soil and roots using low-cost and multispectral sensors.

title: Effect of sowing time and density for vegetative and reproductive traits of genotypes of maize landrace in an agroecological system

description: ABSTRACT: Family farmers preserve the tradition of cultivating maize landrace varieties because these plants have characteristics that hybrids lack. The greatest challenge in conserving in situ on-farm genetic diversity is avoiding gene flow and genetic introgression of transgenes to landrace varieties. Thus, farmers are obliged to change sowing times to guarantee temporal isolation since most farms are small, making spatial isolation impossible. The objective of the present work was to evaluate the behavior of maize landrace varieties submitted to different sowing times and densities in an agroecological system. The test was conducted in sub-sub-divided plots, where the main plot was represented by the sowing time, the sub-plot by the genotype, and the sub-sub-plot by the density, with three replications, for two consecutive years. The results demonstrate the effect of sowing time and density on the characteristics evaluated. In western Santa Catarina, the best time to sow seeds of maize landrace varieties in an agroecological system is in September, which is when the varieties expressed the greatest potential at densities from 45,000 to 50,000 pl.ha-1 , but it will not avoid transgene contamination.

title: Harvest times and seed germination of three safflower genotypes

description: ABSTRACT: The safflower (Carthamus tinctoriusL.) has an uneven flowering and fruiting, which can cause problems in seed production and harvesting in regions with hot and humid climates. However, little is known about the optimal safflower harvest time. Therefore, this study evaluated the optimumtiming for seed harvest of three safflower genotypes (2106, S-325, and 7329).The experiment was a randomized complete block design with six replications. The harvest started 16 days after flowering (DAF) and ended at 52 DAF. Ten harvests were made in total. Seed water content, seeds fresh and dry matter, seed germination, and first germination counts were evaluated.Genotypes 2106 and 7329 had germination rates of 79% and 91%, respectively, at 34 and 38 DAF, while genotype S-325 had 90% germination at 37 DAF. Harvesting at 52 DAF combined with a rainy season impaired the germination of safflower seeds. The harvest time most suitable for safflower occurred between 34 and 42DAF, when the seeds have the seed water content between 26% and 33%.

title: Forage yield, structural responses and chemical composition of spineless cactus Orelha de Elefante Mexicana in different water depths and irrigation frequencies

description: ABSTRACT: The objective was to evaluate the effects of water depths and irrigation frequencies on structural responses, forage yield and chemical composition of spineless cactus Orelha de Elefante Mexicana (OEM) (Opuntia stricta (Haw.) Haw), in adensed crop system. The experimental design was randomized blocks, in subdivided plots (3x4) with 4 replicates. The water depths were (100%, 75%, 50%, and 25% of ETc - crop evapotranspiration) and three water application frequencies (7; 14 and 28 days between irrigations). There was interaction for water use efficiency (WUE) and plant dry mass. Increasing water depths reduced WUE for all irrigation frequencies and plant dry mass was lower for 7 days compared to 14 and 28 days in 25% ETc. Greater water depths increased linearly the plant height and plant width. First and second order cladode length, second order cladode dry mass (kg), fresh mass yield (FMY) (kg ha-1) and dry mass yield (DMY) (kg ha-1) had a quadratic response with the increase in water depth. The FMY and DMY increased up to 77% and 75% ETc, respectively. Irrigation frequency (28 days) promoted greater first order cladode length and cladode dry mass compared to 7 days. Cladode thickness in plant and basal cladode thickness were greater for 7 days compared to 28 days and 14 and 28 days, respectively, without influence on FMY and DMY. Irrigation frequencies from 7 to 28 days promotes similar forage production and water depths up to 77% ETc favors the forage yield for spineless cactus Orelha de Elefante Mexicana receiving supplemental irrigation.

title: Relationship among productive and economic variables of beef cattle in Brazil

description: ABSTRACT: The present study aimed to obtain, through statistical methods, the independent variables that influence the economic and productive results of Brazilian beef cattle. Economic and productive information was collected from 106 farms in Brazil. Data collection was performed by the Instituto de Métricas Agropecuárias (Inttegra). The variable selection method used was stepwise regression followed by polynomial regression analyses. The variable beef cattle economic result showed the positive effect of disbursement per head per month and average weight gain. An average daily gain of 520 g in live weight was obtained, and this variable was influenced especially by nutrition cost. The arroba production (arroba is a unit of weight corresponding to 15kg) was influenced by the linear effect of nutrition cost and stocking rate. The variable arroba production in pasture showed a linear and positive effect of average weight gain in pasture and stocking rate in pasture. For profit per arroba, the variables nutrition cost, disbursement with pasture, and average sale price had a linear effect. The independent variables that had the greatest influence on the response variables were stocking rate, average daily weight gain, and nutrition cost. Thus, increases in investment in nutrition and stocking rate should result in higher production rates and improvements in the profitability of this activity.

title: Distribution of Meloidogyne species in carrot in Brazil

description: ABSTRACT: Root-knot nematodes (RKN - Meloidogyne spp.) are one of the most serious threats to carrot production worldwide. In Brazil, carrots are grown throughout the year, and economic losses due to RKN are reported. Since little is known on the distribution of RKN species in carrot fields in Brazil, we collected plant and soil samples from 35 fields across six states. Based on the morphology of perineal patterns, esterase phenotypes and species-specific PCR, three Meloidogyne species were identified: 60% of the fields were infested with Meloidogyne incognita, M. javanica was reported in 42.9% of the areas, whereas M. hapla was detected in 17.1% of carrot fields. Mixed populations were reported in 20% of the areas with a predominance of M. incognita + M. javanica. The combination of morphological, biochemical, and molecular techniques is a useful approach to identify RKN species.

title: Severe mammary fibroepithelial hyperplasia due to single injection of medroxyprogesterone acetate in two male cats

description: ABSTRACT: Thirty and forty days after a 50 mg medroxyprogesterone acetate injection, respectively, two mixed-breed, 7 and 8-month-old entire male cats presented diffuse enlargement of thoracic and abdominal mammary glands, with ulceration, abscessation and necrosis. One patient was treated with 10 mg/kg aglepristone, antibiotic therapy, analgesic and non-steroidal anti-inflammatory compound; however a worse enlargement of mammary glands, necrosis and clinical condition was noted two days after antiprogestin injection. The second patient was submitted to surgical procedure without previous medical treatment. A partial bilateral mastectomy and conventional orchiectomy were performed, and both patients presented no clinical abnormalities 10 days after surgical treatment. In the male cat, the interruption of progesterone associated mammary fibroepithelial hyperplasia cannot be based in gonadectomy, being antiprogestin treatment the primary approach. Mastectomy can be a treatment option in selected cases, such as the two cases presented here, in case of antiprogestin treatment failure or in case of extensive ulceration, necrosis and risk of sepsis.

title: Genetic traceability of Staphylococcus aureus strains isolated from primiparous dairy cows mastitis, humans and environment in the Northeast region of Brazil

description: ABSTRACT: This research aimed to investigate the genotypic relatedness of 18 Staphylococcus aureus strains isolated from intramammary infections in primiparous cows and extramammary sites on five dairy herds by rep-PCR using RW3A primers, and by PFGE using the endonuclease SmaI. The isolates were also evaluated in vitro for the susceptibility against beta-lactam antimicrobials drugs (penicillin and oxacillin), considering that beta-lactams are frequently used for treating staphylococcal intrammamary infections. The rep-PCR typing was highly discriminatory (D value= 0.9804) and a total of 15 patterns were detected. The PFGE method was also highly discriminatory (D value= 0.9667) and a total of 13 patterns were observed. A total of 15 out of 18 (83%) isolates were resistant to penicillin and one out of 18 (6%) to oxacillin. In conclusion, these findings confirmed the occurrence of a high genetic diversity of S. aureus strains at the herds and the presence of clonally-related strains only at the same herd, emphasizing a variety of genotypic profiles among the isolates.

title: Proximate composition and kinectics drying of sweet pine nuts compared to typical nuts of Araucaria angustifolia

description: ABSTRACT: The objective of this research was to determine the proximate composition and kinetics drying of sweet pine nuts compared to typical pine nuts of Araucaria angustifolia. This study is based on the proximate components, color, and duration of pine nuts drying of both types, and the influence of temperature and cutting geometry on the dehydration process. Sweet pine nuts had lower calorific value and carbohydrate content, but higher lipid, dietary fiber, protein, and ash contents when compared to typical pine nuts. Color of sweet pine nuts is light pink whereas the typical pine nut is yellowish-white. Sweet pine nuts were also softer. Drying kinetics of the seeds fit well into the logistic and Thompson models. To accelerate drying rates, we recommend slicing pine nuts into thin cross-sections and drying them at temperatures of 60 °C for typical pine nuts and 70 °C for sweet pine nuts.

title: Conditioning factors to market fruits and vegetables from family farms to supermarket supply chains

description: ABSTRACT: Globally, increasing number of fruits and vegetables are being consumed to maintain healthy eating habits. Family farming plays a crucial role in fruits and vegetables production; products are marketed in supply chains, which are increasingly demanding, diversified, and complex. Participation of the family farms in each of these supply chains is subject to their ability to meet the increasingly strict participation criteria. In this context, this study identified the main factors that affect the participation of the family farmers in the supermarket supply chains for fresh fruits and vegetables. A systematic literature review was conducted, covering the period from 2005 to 2019. Results indicated eleven variables that affect the participation of the fruits and vegetables family farms in the supermarket supply chains. These variables were grouped in an analytical framework, which comprised four factors: characteristics of the producer, characteristics of the farm, institutional aspects, and available infrastructure. This framework is useful for the development and implementation of the public and private policies for successful participation of fruits and vegetables family farmers in supermarket supply chains.

title: Study of Arboviruses in Philander opossum, Didelphis marsupialis and Nectomys rattus captured from forest fragments in the municipality of Belém, Pará, Brazil

description: ABSTRACT: Arboviruses are viruses that maintain their life cycle in the wild and are transmitted to vertebrate hosts by hematophagous diptera. They are zoonotic and can establish an enzootic cycle in the urban areas; in humans, the infection can manifest from being encephalitogenic to hemorrhagic. This study aimed to report the occurrence of arboviruses in mammals of the order Didelphimorphia and Rodentia, captured from the Amazon. Serum samples were subjected to hemagglutination inhibition test using a viral panel of 19 species of arboviruses that are known to occur in the Amazon. Altogether, 14 wild mammals, 12 of Philander opossum, 1 of Didelphis marsupialis, and 1 of Nectomys rattus were captured. Eight of these were reported to be seropositive for arboviruses (57.14%) with monotypic seroprevalence for the Eastern Equine Encephalitis Virus (n=1), the Ilheus Virus (n=2), and the Catu virus (n=4); 4 heterotypic responses were observed for Flavivirus and Orthobunyavirus. In conclusion, several arbovirus species are in active circulation and maintenance, exhibiting enzootic characteristics in the wild mammals of the Amazon region; these animals prove to be potential hosts in the transmission of diseases to humans.

title: Canal flare index evaluation for different dog breeds

description: ABSTRACT: This study determined the canal flare index (CFI) of four dog breeds using two distinct femoral regions as a reference. Thirty-five radiographs of the hip joints of Golden Retrievers (GRG), German Shepherds (GSG), Labrador Retrievers (LRG), and Rottweilers (RG) of both sexes were used. Seventy experimental units were submitted to CFI calculation. Objective (CFIob) and subjective (CFIsub) values of the CFI of each experimental unit were determined according to the anatomical reference used for the calculation. A significant difference in the CFIob between the Golden Retriever and German Shepherd breeds (1.68 ± 0.16 and 1.49 ± 0.08), and in the CFIsub between Golden Retriever, German Shepherd, and Rottweiler breeds (2.09 ± 0.31, 1.86 ± 0.11, and 1.84 ± 0.18) was reported. The subjective form of measurement showed higher values than the objective form (GRG: 2.09 ± 0.31; GSG: 1.86 ± 0.11; LRG: 2.07 ± 0.12; RG: 1.84 ± 0.18). The CFI values of each breed were similar, suggesting a certain racial pattern. A significant difference in the interobserver assessment for both CFIsub and CFIob, in all races was observed. The CFI analysis identified morphological patterns of the proximal femur in the different races. Results indicated the need for standardization of the anatomical references used to calculate the CFI because there were statistical differences among the measurements among the observers.
