Review on: Response of Cereal Crops to Climate Change

Abstract

Climate change has verified moveable effect in different part of the world, its effect is severe in the developing countries. The adaptation and production of the crops highly affected due to climate change i.e. the ambient weather factors are becoming beyond the suitability ranges. Here, it focuses on the effects of rising atmospheric CO2 concentrations, rising temperature, and changes in precipitation and their interaction on plant growth, development and yield. Therefore, this paper is aimed at reviewing the response of cereal crops to the changing of climate. The existing knowledge sources demonstrated climate change has negative impacts on cereal crops production and productivity. While in some cases these responses are variable within and between species and are dependent on developmental stage. Variability also exists between C3 and C4 species in response to elevated CO2, especially in terms of growth and seed yield stimulation. C3 plants will benefit more than C4 plants at elevated CO2. However, if global warming will take place, an increase in temperature may offset the benefits of increasing CO2 on crop yield. The difference in responses of different crops to elevated CO2 might be due to difference in water, soil, nutrient availability and temperature variation. It concludes that there is a need for further research regarding the weather and climate variability and change together within a specific region.
