| Popis: | In recent years, the use of remote sensing (RS) and geographic information systems (GIS) in observing changes in crop development phases and assessing the impact of various stress factors has been developing around the world. Vegetation indices developed by scientists in the field are widely used in the observation and monitoring of crop conditions, stages of development, biomass and productivity, as well as stress conditions related to water and nutrients. The spectral reflectance characteristics of crops vary under different drought stress conditions. In this article the effect of water shortage on the growth and development of winter wheat is analyzed using satellite data. Within the framework of the research transpiration intensity, water deficiency and water-holding capacity of leaves of winter wheat were studied in climatic conditions of Khorezm region, Uzbekistan. |
