CHEMICAL FERTILIZATION THROUGH FERTIRRIGATION IN THE EVALUATION OF THE BIOCHEMICAL CHARACTERISTICS OF THE WATERMELON FRUITS

The objective of this work was to evaluate the effects of splitting in three different doses of phosphorus and potassium, combined with each other, and it was applied fertirrigation in watermelon crop, and to evaluate their effects on fruit quality. The statistical was in a complete randomized block design, and the treatments were arranged in a factorial scheme (3 x 3) in subdivided splits, resulting in 9 treatments with tree replications, totaling 27 plots in the experimental area. In the horizontal plots the three doses of phosphorus fertilization (100, 150 and 300 kg.ha-1 of P2O5) were randomly allocated, and in the subplots the three potassium doses (50, 100 and 200 kg.ha-1 of K2O), were applied in fertirrigation. The cultivar used was Crimson Sweet. Seventy-Six days after planting (DAP) the biochemical characteristics of watermelon fruits were evaluated: total soluble solids (TSS), total treatable acidity (TTA) and potential of hydrogen (pH). According to the results, it was verified that only the chemical value of the TSS fruits, presented significant statistical differences between the studied doses because of the different source of fertilization K and P increased the soluble solid contents, the content of reducing sugars, and decreased pH. It was observed the different doses of K and P did not influence in the fruit quality parameters when it was analyzed separated: TTA and pH but the TTA values are according to consumer market standards. The best doses in order to economy of fertilizer were (150 kg ha-1 de P2O5 e 50 kg ha-1 of K2O)

Crescimento de três cultivares de bananeira submetida a diferentes doses de nitrogênio e potássio

The objective of this work was to evaluate the response of three banana cultivats 'Terre (AAB)', 'Nanição (AAA)'and'PrataAnã (AAB)' submitted to different of nitrogen and potassium levels, applied to soil in eight periods after planting (DAP). The experiment was conducted in the mesoregion region of Agreste Pernambucano, in Yellow Latosol. The experiment was installed in the experimental area of the Academic Unit of Garanhuns (UAG), UFRPE, in December 2017, spaced 3m x 3m and irrigated by drip irrigation. A randomized block design was used, in a 3x3 factorial arrangement, with 3 replications, totaling 27 factorial combinations. The treatments were composed of nitrogen and potassium simultaneously (NK), as urea and potassium chloride (D1 = N100K100; D2= N150K300 and D3 = N300K600 kg/ha/year of N and K2O) and three cultivats of (C1 = Terra(AAB), C2 = Nanicão (AAA) and C3 = PrataAnã(AAB). The combined doses of N and K favored the vegetative growth of banana plants. The development of the three cultivars, Terra, Nanicão and PrataAnã were influenced by the combined doses of N and K in the period from 150 to 360 days after planting (DAP) of cultivation. The best biometric growth performance results were evaluated for cultivar C1 (Terra - AAB) in the presence of NK dose factor of 100 kg ha-1 year-1 of N and K2O (D1 = N100K100). The lowest values of the growth and vegetative development variables for the three banana cultivars from the beginning to the end of the study period were observed when the dose of NK (D3 = N300K600) was observed.O objetivo deste trabalho foi adequar os níveis de adubação combinada de N e K em três cultivares de bananeira, da ´Terra (AAB)`, ´Nanição (AAA)` e ´Prata Anã (AAB) e verificar a melhor dosagem de N e K para cada cultivar. O experimento foi conduzido na região mesorregião do Agreste Pernambucano, em Latossolo Amarelo. O experimento foi instalado em campo na área experimental da Unidade Acadêmica de Garanhuns (UAG) da UFRPE, em dezembro de 2017, no espaçamento 3m x 3m e irrigado por gotejamento. Empregou-se o delineamento de blocos ao acaso, em arranjo fatorial 3x3, com 3 repetições, totalizando 27 combinações fatoriais. Os tratamentos foram compostos de doses combinadas de nitrogênio e potássio (NK) em cobertura, usando como fonte uréia e cloreto de potássio (D1 = N100K100; D2 = N150K300 e D3 = N300K600 kg ha-1ano-1 de N e K2O) e três cultivares da cultura da bananeira (C1 = Terra (AAB), C2= Nanição (AAA) e C3 = Prata Anã (AAB).

Edoxaban versus warfarin in patients with atrial fibrillation

Contains fulltext : 125374.pdf (publisher's version ) (Open Access)BACKGROUND: Edoxaban is a direct oral factor Xa inhibitor with proven antithrombotic effects. The long-term efficacy and safety of edoxaban as compared with warfarin in patients with atrial fibrillation is not known. METHODS: We conducted a randomized, double-blind, double-dummy trial comparing two once-daily regimens of edoxaban with warfarin in 21,105 patients with moderate-to-high-risk atrial fibrillation (median follow-up, 2.8 years). The primary efficacy end point was stroke or systemic embolism. Each edoxaban regimen was tested for noninferiority to warfarin during the treatment period. The principal safety end point was major bleeding. RESULTS: The annualized rate of the primary end point during treatment was 1.50% with warfarin (median time in the therapeutic range, 68.4%), as compared with 1.18% with high-dose edoxaban (hazard ratio, 0.79; 97.5% confidence interval [CI], 0.63 to 0.99; P<0.001 for noninferiority) and 1.61% with low-dose edoxaban (hazard ratio, 1.07; 97.5% CI, 0.87 to 1.31; P=0.005 for noninferiority). In the intention-to-treat analysis, there was a trend favoring high-dose edoxaban versus warfarin (hazard ratio, 0.87; 97.5% CI, 0.73 to 1.04; P=0.08) and an unfavorable trend with low-dose edoxaban versus warfarin (hazard ratio, 1.13; 97.5% CI, 0.96 to 1.34; P=0.10). The annualized rate of major bleeding was 3.43% with warfarin versus 2.75% with high-dose edoxaban (hazard ratio, 0.80; 95% CI, 0.71 to 0.91; P<0.001) and 1.61% with low-dose edoxaban (hazard ratio, 0.47; 95% CI, 0.41 to 0.55; P<0.001). The corresponding annualized rates of death from cardiovascular causes were 3.17% versus 2.74% (hazard ratio, 0.86; 95% CI, 0.77 to 0.97; P=0.01), and 2.71% (hazard ratio, 0.85; 95% CI, 0.76 to 0.96; P=0.008), and the corresponding rates of the key secondary end point (a composite of stroke, systemic embolism, or death from cardiovascular causes) were 4.43% versus 3.85% (hazard ratio, 0.87; 95% CI, 0.78 to 0.96; P=0.005), and 4.23% (hazard ratio, 0.95; 95% CI, 0.86 to 1.05; P=0.32). CONCLUSIONS: Both once-daily regimens of edoxaban were noninferior to warfarin with respect to the prevention of stroke or systemic embolism and were associated with significantly lower rates of bleeding and death from cardiovascular causes.
