The effects of fully mechanized pruning systems on physiology, vigor and yield of grapevines have been studied for more than forty years and are an interesting way to reduce production costs. Organic amending of vineyard soil is a way to increase vine productivity. Thus, this study aims to understand the effects of the interaction between these two practices, on vine growth and productivity. Two trial fields were implemented on Shiraz vineyards in 2 different wine regions. Mechanical hedge pruning was compared with hand spur pruning and four different organic amendments were tested: biochar; municipal solid waste compost; cattle manure; sewage sludge. Mechanical pruning and organic amendments, by themselves, did not significantly increase yield. However, the interaction between both factors reduced the impact of self-regulation mechanisms (budburst, bud fruitfulness and cluster weight) in mechanical pruning and successfully increased yield, without decreasing vegetative growth. The effects of mechanical pruning with the application of organic amendments to soil on yield is significant and, thereby, the choice of the organic amendment and its amount, must be done considering the destiny of produced grapes.

Aim: The interaction of mechanized pruning systems and soil organic amendment can increase vine productivity. However, since the increase in productivity may affect grape composition, this study aimed to understand the effects of the interaction between these two practices.Methods and materials: Two field trials were implemented in Shiraz vineyards in two different wine regions. Mechanical hedge pruning was compared with hand spur pruning and four different organic amendments were tested: biochar, municipal solid waste compost, cattle manure and sewage sludge.Results: Mechanical pruning reduced the total soluble solids (TSS) and pH of the grapes, but had no effects on the other variables. Organic amendments also reduced TSS, especially sewage sludge, and tended to reduce total anthocyanins and total phenols. The effect of the interaction between both factors on grape composition was never significant. A negative relationship between yield and TSS was observed, while titratable acidity had no relationship with yield. Total anthocyanins were also negatively related to yield. A positive relation between TSS and total anthocyanins was also observed.Conclusions: The results show that the combination of mechanical pruning and soil organic amendment is a powerful tool for increasing productivity, but it has some effects on grape composition.Significance and impact of study: The reduction in some fruit composition variables showed that, while mechanical pruning does not significantly affect grape composition, the choice of type and amount of organic amendment will depend on the destination of the grapes.

The interaction of mechanized pruning systems and soil organic amendment can affect vine vegetative and reproductive growth. However, since organic amendments supply several mineral elements, namely heavy metals, this study aimed to understand the effects of the interaction between these two practices on the mineral composition of wine. Two field trials were implemented in ‘Syrah’ vineyards in two Portuguese wine regions (Lisboa and Tejo). Mechanical hedge pruning was compared with hand spur pruning and four different organic amendments were tested: biochar, municipal solid waste compost, cattle manure and sewage sludge. The nitrogen (N), phosphorus (P) and potassium (K) wine contents were significantly reduced by mechanical pruning while calcium (Ca) and magnesium (Mg) contents were tendentially higher in this pruning system. Mechanical pruning also reduced the content of some minor elements, such as arsenic (As), molybdenum (Mo) and nickel (Ni). In 2014, the year with the higher reproductive growth, some other elements also decreased as a consequence of the mechanical pruning (gallium - Ga; lithium – Li; rubidium - Rb, thallium – Tl; yttrium - Y). Concerning the organic amendments, sewage sludge was associated with the wines with the lowest P and iron (Fe) content. Ca content was tendentially higher in municipal solid waste compost and sewage sludge treatments. Mechanical pruning and organic amendments had different effects on the mineral composition of wine, according to each specific element. However, the legal limits, recommended by OIV and established by European Union, as well as the technical limits, adopted by winemakers, were never exceeded and the interaction of both practices does not seem to be a problem in what concerns to the mineral composition of the produced wines.

A questão de gênero é apontada como influenciadora do processo de adoecimento, com desafios de conciliação dos papéis da mulher atual. Objetivo: estudar percepção de qualidade de vida de trabalhadoras da saúde no contexto da pandemia de COVID-19, descrevendo dados do cenário vivenciado no processo de enfrentamento institucional. Metodologia: estudo descritivo, com base em atividades de promoção à saúde ocupacional, com adesão exclusivamente feminina, que sofreram modificações com a pandemia. A manutenção das ações ocorreu através de levantamento da qualidade de vida (QV), com questões sociodemográficas associadas ao WHOQOL-Bref da OMS, estruturado em domínios – físico, psicológico, relações sociais e meio ambiente – e oferta de auriculoterapia, caso necessário. Variáveis foram analisadas com teste Kruskal-Wallis, significância de 5% (p < 0,05) e teste de Spearman, aplicado para correlação entre domínios. Resultados: a QV foi tida como regular na amostra de 119 trabalhadoras, com predominância da faixa etária até 60 anos, casadas, sem fatores de risco, com filhos, todos maiores de 18 na maioria. Observou-se: pior média no domínio de meio ambiente (3,29) e melhor no de relações sociais (3,77); correlação positiva principalmente entre os domínios de meio ambiente com físico e de relações sociais com psicológico; menor QV com fatores de risco (3,47); piores domínios físicos até 60 anos (3,51) e com pelo menos um filho menor de 18 (3,41); indiferenças para número de filhos e situação conjugal. Conclusão: é relevante explorar fatores que interfiram na QV de trabalhadoras, considerando diferenças regionais. A área da saúde é predominantemente feminina, estratégias individuais, coletivas e organizacionais devem ser elaboradas a fim de acompanhar o fluxo e oferecer suporte. Acredita-se que questões inerentes ao domínio de relações sociais possam atuar de forma protetiva para outros domínios, contribuindo para adaptações e enfrentamento diante dos desafios.
