Abstract: Edible seeds and nuts can contribute to an adequate intake of protein, particularly in vegetable-based diets. However, there are relatively few reports with insufficient data regarding the protein quality of these foods, especially of edible seeds and nuts from Brazil. The aim of this study was to investigate the chemical composition and in vivo protein quality of two edible seeds (baru almond and peanut) and two nuts (Brazil nut and cashew nut) grown in Brazil. The proximate composition and the amino acid profile were analyzed. The true protein digestibility and the protein quality of these foods were evaluated by bioassay with male weanling Wistar rats over a period of 14 days, and the Protein Digestibility Corrected Amino Acid Score (PDCAAS) was estimated. Edible seeds and nuts presented high contents of proteins (16.3 to 32.3 g/100g), lipids (42.7 to 57.9 g/100g) and dietary fibers (6.5 to 14.3 g/100g). Lysine was found to be the limiting amino acid in baru almond, peanut and Brazil nut, which had amino acid scores ranging from 71% to 76%. Cashew nut had no limiting amino acid. These foods showed high protein digestibility (around 90%) except for baru almond (75%), and their PDCAAS values varied significantly (57%, for baru almond, and 90%, for cashew nut). The edible seeds and nuts grown in Brazil provide a high density of energy and nutrients and they can be used as complementary sources of proteins.

Abstract: Bacterial wilt, caused by Ralstonia solanacearum, is a major tomato disease in tropical and sub-tropical regions. It is difficult to be managed, since no single measure confers significant contribution for disease control. Among the cultural practices available for disease management, bokashi provides nutrients to the plants, increasing the microbial biomass, improving the quality of the soil and, in some cases, protecting plants against diseases. In this work, we evaluated the effect of three different bokashis (Embrapa—BE; poultry—BP and cattle—BC) in two soils artificially and naturally infested with R. solanacearum, on the suppression of bacterial wilt in tomato. Disease control is discussed upon measurements on the contents of microbial biomass carbon (MBC), on total organic carbon (TOC), on basal respiration (BR), on metabolic coefficient (qCO2) and on microbial coefficient (qMIC). The experiment was implemented in greenhouse, with completely randomized design and factorial arrangement of treatments 2 × 3 (two soils × three bokashis). Disease suppression, assessed through wilt incidence 20 and 30 days after transplanting, was better observed in the naturally infested soil, where BP and BE were more efficient in controling the disease. TOC contents were higher in the artificially infested soil compared to that naturally infested, whereas the qMIC presented higher value for the naturally infested soil, which had greater contribution of MBC. Higher rates of BR and qCO2 were observed for the naturally infested soil with BC, probably indicating high plant stress caused by the disease in this treatment. Moreover, a high and positive correlation coefficient was found between the variables qCO2 and the number of infected plants at 30 days after transplanting. In the artificially infested soil, a negative correlation was found between the number of infected plants at 20 days after transplanting and TOC.

Abstract: Vegetables productions systems are done normally with intense soil tillage causing a strong decline of soil quality. Use of conservation systems can be an alternative to recover this quality. In order to evaluate the effects of such systems on soil organic matter, an experiment has been conducted in randomized blocks design and factorial scheme 3 × 2: three soil management systems (no-tillage; reduced tillage and conventional tillage) and two cover crops (maize single; and intercropping maize with gray velvet bean—Stizolobium niveum); and repeated measures over time. Soil samples were collected before the implementation of the experiment and at the end of each crop cycle until the fifth crop cycle. Carbon associated with humic substances is also determined in 0 - 5 cm, 5 - 10 cm and 10 - 30 cm at the end of the last crop cycle. The SOM content was higher in RT (48.34 g·kg-1) than in the CT (39.48 g·kg-1) at the end of the fifth crop cycle. SOM content in NT (44.92 g·kg-1) was statistically equal to RT and CT, during the same period. In 0 - 5 cm, carbon contents associated to the humic substances present the same behavior of SOM contents in 0 - 10 cm. Probably these results are associated with the capacity of each system to improve superficial contents of SOM stable fractions. It follows that the conservation systems used are alternatives to the cultivation vegetables in order to improve soil organic matter contents.

Abstract: this multi-case study searched to understand why and how food processing industries develop new products and market orientates to compete in the brazilian functional dairy market. it also examines the regulatory framework role in this process. we use case studies as an approach to give evidence of the systemic relations and the existent trade-offs among factors related to innovation. we chose a research design with one unity of analysis (food processors that recently launched new products in the functional dairy market) and multiple case studies (three brazilian dairies of the southern region). the results reveal that the enterprises adopt a second-mover strategy vis-à-vis the multinational competitors. traditionally, this strategy is considered safer and requires lower r&d and marketing investments. however, it erodes branding and also limits financial returns from innovations. the second-mover behavior is consequence of poor market orientation and restricted cooperation with external partners. this "vicious circle" is also enhanced by barriers established by the regulatory framework.

Abstract: with an irrigated area of approximately 710,500 ha in brazil, it is possible to estimate an annual electricity consumption of 1,928 gwh per year due to center pivot systems. considering the need of optimization of the irrigated agricultural production, the energies that are dissipated in the suction pipes, water supply, lateral lines and sprinkler systems are analyzed in this study and an equation is proposed to determine the useful power of center pivot irrigation systems. three center pivot systems located in itamarati i (a government settlement for the landless in the city of ponta por?, state of mato grosso do sul, brazil) were evaluated and measures of energetic efficiency were simulated in order to determine a viable economic configuration to meet the life span of the equipment. the systems were characterized by the energy use and results show that the average irrigation energetic efficiency may be raised from 14.9 to 25.9% leading to a possible reduction of r$ 118,800 per year over 7,200 ha, equivalent to 11% of the yearly expenses with electricity of the whole area.
