Evapotranspiration, leaf area índex and radicular development of irrigated beans
The evapotranspiration process (ETP), the leaf area index (LAI) as well as the radicular development of cv. IPA 74-19 beans (Phaseolus vulgaris) on a mean textured Red Yellow Podzolic soil of São Desidério Project were studied. The mean ETP was 3.9 mm/day, and the maximum, 5.3 mm/day, happened between late in the blooming and the pod shaping up. There was a positive linear correlation between ETP and class "A" tank evaporation (EV), with and everage coefficient of 0.65. During the culture cycle LA! Varied from 0.41 up to 3.73, and 83% in weight of root was concentrated in the 40 superficial centimeters of the soil.
