Response of sugar beet to soil water deficit

Abstract

An investigation was carried out at Rimski Sancevi, experiment field of Institute of Field and Vegetable Crops, Novi Sad in the period 2001-2006, aiming to determine the response of sugar beet to soil water deficit, using crop response factor (ky). The values of ky were derived from the linear relationship between relative seasonal evapotranspiration deficits (1-ETa/ETm) and relative yield loss (1-Ya/Ym). Values of crop response factor in the growing period (ky 0.45) indicated that sugar beet is moderately sensitive to soil water stress in the climatic conditions of the Vojvodina Province.
