Resumo: The work aimed to evaluate the need for pasture irrigation in the soil and climate conditions of Tubarão, SC. Historical series of daily precipitation of Tubarão (02849027 code, latitude 28° 28 ‘ 20 “S, longitude 48° 59 ‘ 28” W) were used during the 1980 to 2011 period. Average reference evapotranspiration values for five days were considered. With the use of the daily water balance technique, water demands and the needs of irrigation in monthly periods were determined, considering soils with water storage capacity (CAD) of 25, 50, 75, 100 and 125 mm. It was observed that there is need for pasture irrigation between the months of October to January, mainly in soils with low CAD. Soils with 25 CAD require on average 31.8 irrigations per year. Irrigation can be an important tool to keep pasture production and should be planned in such a way as to supplement rainfall.

Utilizou-se a série histórica de precipitação diária de Tubarão (código 02849027, latitude 28°28’20”S, longitude 48°59’28”W) do período de 1980 a 2011. Foram utilizados os valores de evapotranspiração de referência médios por pêntada. Com o uso da técnica do balanço hídrico diário determinaram-se as demandas hídricas e as necessidades de irrigação em períodos mensais, admitindo solos com capacidade de armazenamento de água (CAD) de 25, 50, 75, 100 e 125mm. Foi observado que há necessidade de irrigação nas pastagens entre os meses de outubro e janeiro, principalmente em solos com baixa CAD. Solos com CAD de 25mm necessitam, em média, de 31,8 irrigações por ano. A irrigação pode ser uma ferramenta importante para manter a produção da pastagem e deve ser planejada de forma a suplementar a precipitação.
