| Abstract: The objective of this work was to define the best alternative methods for estimating the reference evapotranspiration (ETo) in the main climatic types (Cfa and Cfb) of the state of Paraná, Brazil. The methods tested were Budyko, Camargo, Hargreaves-Samani, Linacre, and Thornthwaite, which were compared to the ETo calculated with the Penman-Monteith ASCE (EToPM) method, between 1986 and 2015, in eight meteorological stations. The performance of the alternative methods was obtained from the coefficient of determination (R2), index “d” of agreement, index “c” of performance, and root mean square error (RMSE). The Hargreaves-Samani method has a better performance in estimating the ETo for the main climatic types in the state of Paraná. The Camargo... |

| Abstract In a site with a Cfa-type climate in southern Brazil, the water requirements and restrictions for the cultivation of sugar cane (Saccharum spp.), in plant and soca (second cut) were characterized. Water availability was calculated based on the daily water balance and evapotranspiration was estimated using the Penman-Monteith method. The thermal and water requirements of sugarcane were calculated taking as reference the agroecological zoning in the state of Paraná, Brazil. Water requirement index did not show limiting factors for the development of the crop both in plant and soca. Water deficit was the most important agroclimatic risk factor. In Paranavaí-PR, Brazil, sugarcane is a safe crop, with possibilities of saving water in the development... |
