Variabilidade temporal da umidade do solo no sistema plantio direto e plantio convencional irrigados por aspersão na cultura do feijão de inverno.

Abstract

The aim of this research work was to evaluated the soil water and its influence on bean crop production associated to no-tillage and tillage systems, submitted to sprinkle irrigation system. A trase model TDR humidity control system was employed to monitor soil humidity profile soil at depth of 20 cm during all the crop cycle. Obtained data showed no-tillage system presented higher soil water when compared with the conventional tillage system, providing an increase in the average production with less consumer of water.
