Field crop production must adapt to the challenges generated by negative consequences of climate change. Yield loss caused abiotic stresses could be counterbalanced increasing atmospheric CO2 concentration, but C3 plant species and varieties have significantly different reactions CO2. To examine responses wheat, barley oat enrichment in combination with simulated drought, a model experiment was conducted under controlled environmental conditions. The plants were grown climate-controlled greenhouse chambers ambient enriched (700 ppm 1000 ppm) concentrations. Water shortage induced discontinuing irrigation at BBCH stages 21 55. Positive determined barley, CO2-sink ability low oats. Reactions winter wheat concentration varied greatly terms yield parameters (spike number grain yield). water uptake all cultivars decreased significantly; however same time, water-use efficiency improved Mv Ikva not susceptible fertilization, while no consequent observed for Nádor Nemere.
