Abstract: Actual evapotranspiration (ET) and crop coefficient (Kc) were modelled in a commercial farm with corn crop. The plots were irrigated by central pivots for grain and silage, in the north-western side of São Paulo State, Brazil. For ET acquirements, the SAFER (Simple Algorithm For Evapotranspiration Retrieving) algorithm was applied to Landsat satellite images during growing seasons (GS) from March to August of 2010. Polynomial functions relating Kc and the accumulated degree-days (DDac) allowed the estimation of evapotranspiration under potential conditions (ETp). Adding data on reference evapotranspiration (ET0), precipitation (P), irrigation (I) and productivity (Yp), irrigation performances were assessed. The Relative Evapotranspiration (RET) ranged from 0.78 to 1.00 and the Water Deficit (WD) presented a maximum of 110 mm GS-1. The Relative Water Supply (RWS) with values from 1.1 to 1.4 indicated high drainage rates. The physical values of water productivity, based on ET (WPET) ranged from 1.4 to 2.8 kg m-3 for grains and from 8.8 to 14.1 kg m-3 for silage, with the corresponding monetary ones for grains from 0.34 to 0.68 US$ m-3, showing high return when comparing with other annual crops.

Key words: Remote sensing, evapotranspiration, crop coefficient, degree-days.


Resumo: A evapotranspiração atual (ET) e coeficiente de cultura (Kc) foram modelados em uma fazenda comercial com a cultura do milho. As parcelas foram irrigadas por pivôs centrais para grãos e silagem, no lado noroeste do Estado de São Paulo, Brasil. Para obtenção da ET, o algoritmo SAFER (Simple Algorithm For Evapotranspiration Retrieving) foi aplicado em imagens do satélite Landsat durante os ciclos produtivos (CP) de março a agosto de 2010. Funções polinomiais relacionando o coeficiente de cultura (Kc) com os graus-dias acumulados (GDac) permitiram a estimativa da evapotranspiração em condições  potenciais (ETp). Adicionando dados de evapotranspiração de referência (ET0), precipitação (P), irrigação (I) e produtividade (Yp), os desempenhos de irrigação foram analisados. A Evapotranspiração Relativa (RET) ficou entre 0,78 e 1,00 enquanto que a Deficiência Hídrica (WD) apresentou um máximo de 110 mm CP-1. O Suprimento de Água Relativo (RWS) com valores de 1,1 a 1,4 evidenciou altas taxas de drenagem. Os valores físicos da produtividade da água, baseada na ET (PAET) estiveram entre 1,4 e 2,8 kg m-3 para grãos e de 8,8 a 14,1 kg m-3 para silagem, com os monetários correspondentes para grãos de 0,34 a 0,68 US$ m-3, apresentando elevado retorno quando comparados com outras culturas anuais.

Palavras-chave: Sensoriamento remoto, evapotranspiração, coeficiente de cultura, graus-dias.
