Resumen

DE OLIVEIRA MANGAROTTI, Danielle Paula et al. Water requirements and crop coefficients of arugula grown in a protected environment. Idesia [online]. 2019, vol.37, n.2, pp.75-79. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292019000200075.

Maintaining an adequate water supply is essential to obtain maximum yields in vegetable crops. As such, this study aimed to determine the water requirements (ETc) and crop coefficients (Kc) of arugula grown in a protected environment under subtropical climate conditions. The experiment was conducted in a greenhouse at the Center for Irrigation Technology of the State University of Maringá in Maringá, Paraná state (PR), Brazil. Crop evapotranspiration (ETc) was determined using three constant water table lysimeters and reference evapotranspiration with the Penman-Monteith equation. The total water consumption of the arugula crop was 113.27 mm. The average values obtained for the crop coefficients in the initial, mid- and late-season stages were 1.92, 1.03 and 1.80, respectively.

Palabras clave : Eruca sativa; evapotranspiration; irrigation.
