Evaluation of alfalfa (Medicago sativa L.) populations’ response to salinity stress
(2017-02)Alfalfa (Medicago sativa L.) is a moderately salt-tolerant crop with high economic return and is therefore more suitable for production with lower quality water than most high-value crops. This study was conducted to examine ... -
Evaluation of different methods of estimating ET for the performance assessment of irrigation schemes
(Elsevier, 2021-01)In the assessment of irrigation schemes, the accuracy of performance indicators related to the water balance could be improved by estimating crop evapotranspiration (ETc) using remote sensing techniques. The two main remote ... -
Exploring the biological activity of condensed tannins and nutritional value of tree and shrub leaves from native species of the Argentinean Dry Chaco
(2017)BACKGROUND: Tropical tree or shrub leaves are an important source of nutrients for ruminants and a potential source of biologically active compounds that may affect ruminalmetabolism of nutrients. Therefore, eightwoody ... -
