Water shortage may lead to the shortage of food for Arab states (famines), poverty and divisions. Therefo...
Maize originated under warm, seasonally dry conditions of Mesoamerica, and was by human selection converted from a low-yielding progenitor species into its modern form, with a large rachis (cob) of the female inflorescence bearing up to 1,000 seeds. Maize is a C4 plant and is very efficient in water use. If subjected to water stress, however, especially during the mid-season pollination process...
River ow forecasts are required to provide basic information for reservoir management in a multipurpose water system optimisation framework. An accurate prediction of ow rates in tributary streams is crucial to optimise the management of water resources considering extended time horizons. Moreover, runo3 prediction is crucial in protection from water shortage and possible ood damages. In this p...
To ensure the selection of wheat genotypes that are resilient to future climatic conditions, with drought already being most significant and acute problem in many areas, twenty winter cultivars were tested for stress tolerance from beginning stem elongation (DC 30; Zadoks decimal codes) 49 days (until stage grain development, DC 73–75) within an automatic phenotyping platform. The control plant...
