Abstract

The maximum yield potential of potato cultivars and the quality of the tubers are directly related to soil water availability. Thus the aim of this study was to evaluate the effect of different irrigation depths on the agronomic characteristics of different potato cultivars in the northeast of Mato Grosso do Sul State, Brazil. The experiment was conducted in Universidade Federal de Mato Grosso do Sul, campus de Chapadão do Sul, Brazil, using the experimental design of randomized blocks in a split plot design with four replications, in plots with four irrigation depths (50, 75, 100 and 125% of the amount of water to compensate for the loss of water by culture evapotranspiration) and the subplots, potato cultivars (Asterix, Atlantic and CLL). We assessed the results by number of tubers per plant, average tuber mass, business yield and water use efficiency (WUE). The increase in irrigation depth provides a reduction in water use efficiency by the potato; and does not affect the other parameters. The Asterix potato is to be preferred by farmer’s Northeast Mato Grosso do Sul State.
