Determinação do consumo e água da alface (Lactuca sativa L. ) pelo método lisimétrico.

Abstract

The present study was undertaken through May - July, utilizing four lysimeters installed at “Fazenda do Glória”, property of Universidade Federal de Uberlândia, Uberlândia,MG., with the objective of determining water consumption of a lettuce (cultivar Carolina) crop. The crop coefficient (Kc) was determined through the relationship between the crop evapotranspiration given by the lysimeter method and the evapotranspiration found by the “class A” tank method. The crop coefficient obtained ranged from 0.64 to 1.00 and the daily average water consumption was 3.35 mm.
