Not exact matches

Two of the most efficient were Rubisco from plants known as Aegilops cylindrica (jointed goatgrass) and Hordeum vulgare (barley), which both showed promising Rubisco catalytic properties that should be explored in the context of improving photosynthesis, and ultimately grain yield, in wheat.

Subsequently cited in 54 papers, the Science study showed that even using the lower end of 23 climate models suggested that in the tropics at the end of the century, «the hottest seasons on record will represent the future norm in many locations,» with the devastating impacts on wheat and rice yields.

Instead, it shows the predicted change in Kansas wheat yields if we were to experience a 1 degree (C) increase (1.8 degrees F) in temperature.

Their results showed that from 1985 through 2011, wheat breeding programs boosted average wheat yields by 13 bushels per acre, or 0.51 bushel each year, for a total increase of 26 percent.

Research shows that reduced precipitation is already holding back wheat yields.

U.S. Department of Agriculture data tables provide evidence for the importance of the eight Midwest states for U.S. agricultural production.3 Evidence for the effect of future elevated carbon dioxide concentrations on crop yields is based on scores of greenhouse and field experiments that show a strong fertilization response for C3 plants such as soybeans and wheat and a positive but not as strong a response for C4 plants such as corn.

Observational data, evidence from field experiments, and quantitative modeling are the evidence base of the negative effects of extreme weather events on crop yield: early spring heat waves followed by normal frost events have been shown to decimate Midwest fruit crops; heat waves during flowering, pollination, and grain filling have been shown to significantly reduce corn and wheat yields; more variable and intense spring rainfall has delayed spring planting in some years and can be expected to increase erosion and runoff; and floods have led to crop losses.4, 5,6,7

«All aspects of food security are potentially affected by climate change including food access, utilisation of land, and price stability,» said Revi, adding that studies showed wheat and rice yields were decreasing due to climatic changes.

Whilst wheat and maize show bigger «missed yield increases» from rising temperatures, soya beans and rice show no effect yet on their yields.

«Our results show that maize yields are expected to be negatively affected by climate change, while the impacts on wheat and soybean are generally positive, unless CO2 fertilisation effects have been overestimated»....
