Yield and leaf area index estimations for sunflower plants using unmanned aerial vehicle images.

Vegetation is commonly monitored to improve efficiency of various agricultural practices. Spatial and temporal changes in plant growth and development can be monitored with the aid of remote sensing techniques employing ground, aerial, and satellite platforms. Unmanned aerial vehicles (UAV) and multi-spectral cameras developed for UAVs have an important potential for agricultural management activities with high-resolution spatial and temporal images.

Potential use of remote sensing techniques in evapotranspiration estimations at watershed level.

In hydrology, evapotranspiration (ET) is defined as phase conversion and rise of water in soils, plants, rivers, lakes, and seas under the atmospheric conditions. Investigation of water displacement through either ET or precipitations, runoffs and infiltrations may provide significant contributions for water resources management practices. In this study, daily, monthly, and seasonal ET maps were generated for Minöz Stream Watershed of Kavak town of Samsun province with the aid of energy balance-based METRIC model for the water-year of 2007.
