An investigation was carried out at Rimski Sancevi experimental field of Institute for Field and Vegetable Crops in Novi Sad (Serbia) during the period of 1997-2007, aiming to determine the sensitivity of maize to soil water deficit at specific growth stages. The values of yield response factor (ky) were derived from the linear relationship between relative seasonal evapotranspiration deficit (1-ETa/ETm) and relative yield loss (1-Ya-Ym). The obtained results indicate that under climatic conditions of the Vojvodina Province (Serbia) maize is the most sensitive to water stress in the stage of flowering and fertilization (ky 0.49), but less sensitive by the beginning and at the end of growing season in the stage of vegetative growth (ky 0.46) and grain filling and maturity (ky 0.43). Values of yield response factor in the growing period (ky 0.65) indicate that maize is moderate sensitive to soil water stress under the climatic conditions of Vojvodina.
