Indicadores técnicos e econômicos do maracujazeiro amarelo irrigado com fonte de água subterrânea

The research aimed to quantify technical and economic indicators of yellow passion fruit tree irrigated with fractions of irrigation with underground source of water, to generate information that helps farmers in decision making on the implementation of investment in irrigated fruit growing (yellow passion fruit). For this purpose, we used the passion fruit crop irrigated with Microjet type irrigation system, with conducting system in simple espaliers. The treatments consisted of five hours of application of the depth of water required by the crop with irrigation frequency of two days. The results showed that the highest yield (16660kg ha-1) was obtained with the fractionation of irrigation twice a day (50% to 7h and 50% to 21h30), which provided an increase in productivity of 54%, demonstrating the financial viability and being highly profitable to the interest rate of 2% per year, with low sensitivity of financial risk to real interest rates above the prevailing market.O trabalho teve como objetivo quantificar indicadores técnicos e econômicos do maracujazeiro-amarelo irrigado com fracionamento da irrigação com fonte de água subterrânea, de forma a gerar informações que auxiliem os agricultores na tomada de decisão sobre a aplicação de seus investimentos na fruticultura irrigada (maracujá-amarelo). Para tanto, utilizou-se da cultura do maracujá, irrigado com sistema de irrigação tipo microjet, sob a forma de condução em espaldeiras simples. Os tratamentos constaram da combinação de horários de aplicação da lâmina de água requerida pela cultura, com frequência de irrigação de dois dias. Os resultados permitiram concluir que a maior produtividade (16.660 kg ha-1) foi obtida com o fracionamento da irrigação em duas vezes ao dia (50% às 7h e 50% às 21h30), a qual proporcionou um incremento de produtividade de 54%, demonstrando viabilidade do ponto de vista financeiro e altamente lucrativo à taxa de juros de 2% ao ano, com baixa sensibilidade de risco financeiro a taxas reais de juros acima das praticadas no mercado.94095

Produtividade e análise de indicadores técnicos do maracujazeiro-amarelo irrigado em diferentes horários.

Diante da necessidade de pesquisas sobre o manejo da irrigação em horários alternativos e com menor custo com eletricidade na produção do maracujá-amarelo irrigado objetivou-se, com esta pesquisa, avaliar os efeitos do fracionamento da irrigação em diferentes horários de aplicação sobre a produtividade e qualidade do fruto do maracujazeiro-amarelo tal como, também, a quantificação de indicadores técnicos; para tanto se conduziu um experimento no município de Pentecoste, CE, no período de setembro de 2009 a agosto de 2010, no delineamento em blocos ao acaso com cinco tratamentos e quatro repetições. Os tratamentos corresponderam aos horários de aplicação da lâmina de água requerida (LR) pela cultura (T1: 100% da LR às 07 h; T2: 50% da LR às 07 h e 50% da LR às 15 h; T3: 25% da LR às 07 h; 50% da LR às 15 h e 25% da LR às 21 h 30 min; T4: 100% da LR às 21 h 30 min: T5: 50% da LR às 07 h e 50% da LR às 21 h 30 min). De acordo com os resultados a aplicação fracionada da lâmina de água requerida pela cultura com 50% às 07 h e 50% às 21 h 30 min, foi a alternativa que proporcionou a maior produtividade do maracujazeiro; os atributos de qualidade dos frutos de maracujazeiro sólidos solúveis totais e pH se mantiveram indiferentes quanto aos tratamentos

Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representative studies with 104 million participants

Background Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. Methods We used data from 1990 to 2019 on people aged 30–79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prevalence of hypertension and the proportion of people with hypertension who had a previous diagnosis (detection), who were taking medication for hypertension (treatment), and whose hypertension was controlled to below 140/90 mm Hg (control). The model allowed for trends over time to be non-linear and to vary by age. Findings The number of people aged 30–79 years with hypertension doubled from 1990 to 2019, from 331 (95% credible interval 306–359) million women and 317 (292–344) million men in 1990 to 626 (584–668) million women and 652 (604–698) million men in 2019, despite stable global age-standardised prevalence. In 2019, age-standardised hypertension prevalence was lowest in Canada and Peru for both men and women; in Taiwan, South Korea, Japan, and some countries in western Europe including Switzerland, Spain, and the UK for women; and in several low-income and middle-income countries such as Eritrea, Bangladesh, Ethiopia, and Solomon Islands for men. Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59% (55–62) of women and 49% (46–52) of men with hypertension reported a previous diagnosis of hypertension in 2019, and 47% (43–51) of women and 38% (35–41) of men were treated. Control rates among people with hypertension in 2019 were 23% (20–27) for women and 18% (16–21) for men. In 2019, treatment and control rates were highest in South Korea, Canada, and Iceland (treatment >70%; control >50%), followed by the USA, Costa Rica, Germany, Portugal, and Taiwan. Treatment rates were less than 25% for women and less than 20% for men in Nepal, Indonesia, and some countries in sub-Saharan Africa and Oceania. Control rates were below 10% for women and men in these countries and for men in some countries in north Africa, central and south Asia, and eastern Europe. Treatment and control rates have improved in most countries since 1990, but we found little change in most countries in sub-Saharan Africa and Oceania. Improvements were largest in high-income countries, central Europe, and some upper-middle-income and recently high-income countries including Costa Rica, Taiwan, Kazakhstan, South Africa, Brazil, Chile, Turkey, and Iran. Interpretation Improvements in the detection, treatment, and control of hypertension have varied substantially across countries, with some middle-income countries now outperforming most high-income nations. The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings
