title: Production and morphological components of sunflower on soil fertilized with cassava wastewater

description: ABSTRACT Agroindustrial residues, such as cassava wastewater, have been used as soil fertilizers, reducing environmental pollution and recovering nutrients. The objective of this work was to evaluate production and morphological components and oil yield of sunflower (Helianthus annuus), hybrid Helio-250, fertilized with cassava wastewater. The experiment was conducted at the Experimental Station of the Instituto Agronomico de Pernambuco, Vitória de Santo Antão, State of Pernambuco, Brazil. A randomized block experimental design was used, with six cassava wastewater rates (0, 8.5, 17.0, 34.0, 68.0 and 136 m3 ha-1) and four replications. The variables evaluated were shoot fresh and dry weight, capitulum fresh and dry weight, capitulum diameter, seed yield, oil yield and seed oil content. The use cassava wastewater as soil fertilizer improved the production and morphological variables evaluated, except the seed oil content, which decreased with application of cassava wastewater rates above 25 m3 ha-1.

title: External fixation to correct tarsal-metatarsal fracture in rock pigeon (Columba livia)

description: ABSTRACT Orthopedic conditions, such as bone fractures, are very common in avian medicine. External fixators have been considered the gold standard for birds, since they allow early movement of the limbs and minimal invasive surgery. Fractures in several bones have been successfully treated in pigeons. However, to the best of our knowledge, this case represents the first report of successful surgical repair of tarsal-metatarsal fracture in rock pigeon. External fixator was made with four 24G catheters, being inserted manually proximal and distal to the fracture and connected with polymerizable acrylic. Radiographic consolidation of fracture was observed 60 days post-surgery and anti-inflammatory and antibiotic protocols were successful on avoiding pain and infection during surgery and bone healing.

title: Profile and behavior of flower consumer: subsidies for marketing actions

description: ABSTRACT The growth of per capita consumption of flowers in Brazil is still low when compared with other countries. Among several factors that may be linked to this growth gap, the establishment of few or ineffective marketing strategies was cited. In this context, we present the results of the profile and behavior of flower consumer, aiming to subsidize marketing actions for the retail segment of flower supply chain. The study was conducted through interviews with 300 people of both genders at the moment they were buying flowers at 22 flower shops in the Paraná coast. This region was selected due to its potential for flower production and commercialization, which is similar to other Brazilian regions and other countries where the flower market has economic relevance. The female gender was identified as the major consumer (n = 62.7%), with tendency of increase in consumption as education level advanced (Spearman correlation coefficient, p &lt; 0.05 = for own use r = 0.122; p = 0.039; for gift r = 0.174; p = 0.003). The acquisition average of 4.4 ± 1.9 times per year was registered, with preferential consumption of orchids (n = 36.3% for own use) and roses (n = 86.7%, for gift). The flower retail trade did not meet the expectations of consumers, especially in relation to price, promotions, and production quality. The male gender and the elderly consumer class may represent important alternatives to increase the current consumption of flowers.

title: Growth performance of castor bean hybrids under different plant densities

description: ABSTRACT Castor bean grown at high plant densities can increase yield due to increased light interception and reduction in sink demand. The objective of this study was to evaluate the effect of plant density on growth of castor bean hybrids. The experiment was conducted in Botucatu, SP, Brazil, in a split plot randomized block design, with four replications, in 2011 and 2012. The main plot consisted of the sampling times and the subplots consisted of a 3x3 factorial, with the 3 genotypes in the first factor and the 3 plant densities in the second factor. The variables analyzed were: dry mass of leaves, stems, racemes, and total dry matter, which were measured at 30, 60, 90, 120 and 150 days after emergence (DAE). Data were examined for significant differences using analysis of variance followed by the F test (p &lt; 0.05). When interaction was found between the factors and sampling the means were analyzed by regression analysis (p &lt; 0.05). Growth performance was higher in 2012 because of the greater water availability. In 2011, under lower rainfall, there was less branching resulting in cycle end, with total leaf loss. High plant densities partially suppress the development of higher-order structures, especially when associated with water restriction.

title: Anatomical adaptations to different soil moisture contents in palisade grass and smooth pigweed

description: ABSTRACT Weed adaptations to different environments contribute to their success in establishing in different agroecosystems. A greenhouse and laboratory study was carried out to evaluate the effects of different levels of soil moisture on the anatomical characteristics of two weed species. The treatments were arranged in a 2 x 5 factorial design, with the first factor representing the weed species (Amaranthus hybridus and Brachiaria brizantha) and the second factor being the soil moisture levels in which they were grown (100%, 80%, 74%, 67%, and 60% of field capacity). At 55 days after weed emergence, the material for anatomical evaluations was collected. The water stress affected the two weed species differently, causing changes both in the thickness of the tissues evaluated and in their proportions. These changes seem to be related to how each species tolerates water stress. A. hybridus showed thickening of all leaf tissue and change in the proportion of these tissues, whereas B. brizantha showed a decrease in thickness of the leaf tissue and an increase in the proportion of adaxial epidermal and parenchymal tissues.

title: Development of frozen yogurt from powdered yogurt of sheep milk

description: ABSTRACT The quest for healthy and unique foods by consumers has raised and encouraged an ever-constant update on skills for professionals who work on the development and research of new products. Sheep milk is a food with high levels of total solids, such as protein and calcium. The current production of sheep dairy products is still low. In this sense, aiming at expanding the market and product range of this raw product, Frozen Yogurt formulations were developed using powdered yogurt of sheep milk, applying an experimental planning 2², with triplicate in the central point. The physicochemical characteristics were evaluated in function of the variables concentration of emulsifier/stabilizer at (0.50, 0.75, and 1.00%) and powder preparation for cream (2.75, 3.00, and 3.25%). Their physicochemical characteristics were also obtained. It was found that the concentration of powder preparation for cream presented a significant positive effect with 95% confidence on protein, lactose, and calcium and a significant negative effect on pH.

title: Study of a droplet electrification system in a backpack sprayer in a Faraday cage

description: ABSTRACT This study evaluated the factors affecting the charge/mass ratio (Q/M) generated by a droplet electrification system in a backpack sprayer with an electrostatic kit, using a Faraday cage. Two experiments were conducted in completely randomized design to determine the effect of application rate, the distance between the nozzle and the target, and spraying mixtures on performance of the droplet electrification system. The first study evaluated four distances (0, 0.5, 1.0, and 2.0 m) between the nozzle and the Faraday cage; the second study was conducted in a factorial design, with five tank mixtures and five flow rates (0.25, 0.76, 1.00, 1.45, and 1.58 L min-1). The Q/M ratio was determined using a multimeter by measuring the electric current from the volume of mixture sprayed in the Faraday cage, which was divided by the respective liquid mass. Droplet spectrum was analyzed by a particle analyzer using laser diffraction. The Q/M ratio became smaller as the spraying flow rate increased, similarly as observed with increasing distances of the electrostatic nozzle from the cage entrance. The Q/M ratio increased with the addition of mineral oil, vegetable oil, and insecticide to the spraying mixture. Flow rate, distance between the nozzle and the target, and the spraying mixture affected the electrostatic spraying efficiency.

title: Characterization and activity of endophytic bacteria from ‘Prata Anã’ banana crop (Musa sp., AAB)

description: ABSTRACT The objective of this study was to characterize banana tree endophytic bacteria at genus and species level and to determine the metabolic reactions associated with the nitrogen transformations. The identification at genus and species levels was performed using the partial sequencing of the rDNA 16S region. The assimbyotic nitrogen fixation, the reduction of nitrate and the production of urease were in vitro evaluated. The DNA of the bacterial isolates was also amplified to verify the presence of the nifH, nirK and nirS regions. Biochemical tests were performed in a complete randomized design; the treatments consisted of 39 bacterial isolates with three replications. Sequence analysis enabled the identification of four genera: Bacillus, Rhizobium, Klebsiella and Enterobacter. The Bacillus genus occurred more frequently, nine species were identified. By evaluating the results of biochemical tests, it was observed that three isolates showed multiple abilities: growth in NFb medium, nitrate reduction and production of urease. The isolates belong to the genus Bacillus and of the species subtilis, thuringienses and amyloliquefaciens. Approximately 12.5% of the isolates amplified the region corresponding to the nifH gene, 7.5% amplified gene nirK and 3.9% amplified the nirS gene. Endophytic bacteria evaluated in the present study showed in vitro activity for urease, nitrate reductase enzymes, however, relevant nitrogenase activity was not observed.

title: Allelopathic potential and identification of secondary metabolites in extracts of Canavalia ensiformis L.

description: ABSTRACT The species that have allelopathic potential are promising in agriculture, with the perspective of identifying their secondary metabolites and manipulating them, for practical applications and thus be used to control weeds. In this context, this work aimed to verify the allelopathic effect and to identify the secondary metabolites in the Canavalia ensiformis species. The Lactuca sativa, Digitaria insularis, Emilia coccinea and Portulaca oleracea species were used as recipient species. To evaluate the allelopathic potential, the ethanolic extract of the aerial part (leaf + stem) of the donor specie was carried out. Potential allelopathic effects were evaluated by germination tests and initial seedling growth. The identification of the secondary metabolites of the aerial part of C. ensiformis was also performed using the High-Performance Liquid Chromatography technique. The ethanolic extract cause inhibition of germination and germination speed index of L. sativa. The aerial part of C. ensiformis contains the compounds belonging to phenolic acids (chlorogenic acid, ferulic acid, caffeic acid), flavonoids (kaempferol, naringin and rutin) and carboxylic acids (citric acid, malonic acid and aspartic acid) they can be responsible for the allelopathic activity of this species.

title: Effect of thermal environment on performance of broiler chickens using fuzzy modeling

description: ABSTRACT This study aimed to develop a decision-support system based on fuzzy set theory, which can estimate welfare depending on the production responses of broiler chickens raised in climatic chambers. In the first phase, the influence of four different air temperature conditions on the performance of broilers was identified. Thus, the effect of air temperature on productivity was evaluated. In the second phase, a model was developed using the fuzzy set theory, in which feed intake responses, weight gain, and feed conversion were established according to age and the air temperature at which the birds were maintained, obtaining an efficient evaluation of the thermal environment. The results indicate that the proposed methodology is a promising technique for the determination of the level of thermal comfort endured by broilers, capable of assisting in making decisions on control of the thermal environment, avoiding productivity losses.

title: Yield and grape must quality of the IAC 138-22 ‘Máximo’ submitted to canopy management

description: ABSTRACT Grape cultivar IAC 138-22 'Máximo' grafted on IAC 766 ‘Campinas’ and IAC 572 ‘Jales’ rootstocks and trained in upright trellis was evaluated during consecutive summer and winter growing seasons for comparison different canopy management: a) branch thinning: comparison between one branch and two branches per spur and b) branch tipping: comparison between low and high upright trellis. The results obtained of the phytotechnical and physicochemical grape must characteristics allowed to confirm that there was no significant difference between rootstocks regarding branch thinning intensity and upright trellis height. The largest effect observed in canopy management was for yield values promoted by branch thinning. No effect was observed in the grape must physicochemical characteristics when the different treatments were compared in the same growing season. Regarding to the upright trellis height, larger values of soluble solids were obtained for the high trellis than in the low trellis. Winter growing season resulted in lower values of yield and greater values of total soluble solids and titratable acidity than in the summer growing season.
