Climate change will hit Indian cereals, benefit legumes
Indian farmers could be producing less rice and wheat and more legumes as a result of global warming, a senior crop scientist has said. Climate change would have a negative impact on cereal crops such as wheat and rice, Bandi Venkateswarulu, director of Central Research Institute for Dryland Agriculture, Hyderabad, told a South Asia media workshop on climate change in Delhi this month (17 ...

Ohio State Expert: Cold Snap Could Injure Wheat Depending on Its Growth Stage
Thanks to last month’s warmer-than-normal temperatures that sped up the growth of wheat crops across Ohio, this week’s cold snap could result in injury for some of those plants. Just how damaging the colder weather will be depends on how advanced the wheat is in its growth stage, said Laura Lindsey, a soybean and small grains specialist with Ohio State University Extension. ...

Rising heat hits Indian wheat crop
Researchers in the UK have established a link between changing climate and agriculture that could have significant consequences for food supplies in South Asia. They have found evidence of a relationship between rising average temperatures in India and reduced wheat production, which was increasing until about a decade ago but has now stopped. The researchers, Dr John Duncan, Dr Jadu Dash and ...

High temperatures `make wheat old before its time`
Global warming can cause premature ageing in wheat, according to computer modelling studies of the crop's response to growing conditions in northern India. The effects of warming on wheat growth and grain size are far worse than previous crop models indicated, David Lobell, assistant professor in environmental earth system science at Stanford University, United States, and colleagues wrote in ...

Cereal Crops Feeling the Heat
LIVERMORE, California (ENS) - Warming temperatures since 1981 have caused annual losses of about US$5 billion for six major cereal crops, new research has found. This is the first study to estimate how much global food production already has been affected by climate change. From 1981 to 2002, fields of wheat, corn and barley throughout the world have produced a combined 40 million metric tons ...

Wheat rust diseases remain a constant but neglected threat
FAO is calling for countries in the global ‘wheat belt’ to step up monitoring and prevention for wheat rusts – fungal diseases that do especially well in particularly wet seasons. Yields could be affected across North Africa, the Middle East into West and South Asia, which account for more than 30 percent of global wheat output and nearly 40 percent of total land area dedicated ...
