Estimativa operacionalizada do coeficiente de cultura (kc) para manejo de irrigação em áreas com exposições Norte e Sul.

Abstract

It was estimated the daily kc values applying the PENMAN-MONTEITH operacionalized model on area elements of a small experimental watershed cultivated with sweet sorghum (Sorghum bicolor L. Moench), with north an south expositions and 0, 20 and 40% declivities at Jaboticabal (21° 15’ 22” S, 48° 18’ 58” W and 575m of altitude), São Paulo state, Brazil. The results obtained allowed to estimate by interpolation, the kc means curves to 5, 10 and 15% of declivitie, to both expositions.
