摘要：
Drought monitoring and plant productivity can be qualitatively evaluated using vegetation indices. In this paper, we combined in-situ reflectance, satellite and agro-meteorological data, in order to obtain and analyze high precision indices corresponding to germination period of some agricultural crops from the Caracal plain, Romania. Sensitivity tests regarding the effect of detection angle and atmospheric conditions on reflectance were estimated. Differences that can be related to the phenological stages of studied crops were noticed in near infrared spectral range. The in-situ and satellite based results, correlated with main agro-meteorological parameters proved to be good indicators of the drought vegetation condition.
