In a unique study set - up, the scientists first compared simulation results from a large ensemble of wheat crop growth models with experimental data, including artificial heating experiments and multi-locational field trials.

Not exact matches

Indeed, the latest traffic figures from Port Metro Vancouver show sharp growth in shipments of wheat and specialty crops, and solid gains in meat, poultry and potash.

Global crop yields were beginning to decline — especially for wheat — raising doubts as to whether production could keep up with population growth.

Cynthia Rosenzweig, a researcher based at Goddard, has been using crop - growth computer models to predict effects of carbon dioxide buildup and climate change on wheat, the most widely cultivated crop in the world.

To find out if how the nitrogen is delivered makes a difference, Arnold Bloom, a crop physiologist at the University of California, Davis, and his team monitored the growth of wheat plants raised in high levels of carbon dioxide.

«We can easily extend our new model to simulate the growth processes of other staple crops, such as soybeans and wheat.

This is a serious problem as the predicted increase in frequency of extreme climate episodes will lead to multiple drought conditions during crop growth which in turn will reduce the yield of wheat, one of the world's most important foods.

Dr. Shabala and his colleagues note that recent research on salt bladders creates the exciting possibility of modifying genes in traditional crops such as wheat or rice to allow them to develop salt bladders without a major impact on their growth and yield.

Many of the same scientists who helped with this study have worked with Asseng on computer models to simulate crop growth and yield, particularly for wheat.

Warmer weather, including hot nights, can speed crop growth but reduce overall productivity for some plants such as wheat and other cereal crops.

Global crop yields were beginning to decline — especially for wheat — raising doubts as to whether production could keep up with population growth.

The heat would also cause staple crops to suffer dramatic yield losses across the globe (it is possible that Indian wheat and U.S. corn could plummet by as much as 60 percent), this at a time when demand will be surging due to population growth and a growing demand for meat.

SciDev.net: China and India, the world's two most populous countries, are beset by stagnation in the production of staples like rice, wheat, soybean and maize (corn), says a new study on crop yield growth.

These climate model outcomes the researchers then translated to crop growth conditions [even including CO2 - fertilisation effects] for maize, wheat and rice, for the different geographical regions.

say it has been predicted that «the average temperature in the semiarid northwest portion of China in 2050 will be 2.2 °C higher than it was in 2002,» and they report that based on the observed results of their study, this increase in temperature «will lead to a significant change in the growth stages and water use of winter wheat,» such that «crop yields at both high and low altitudes will likely increase,» by 2.6 % at low altitudes and 6.0 % at high altitudes... Even without the benefits of the aerial fertilization effect and the anti-transpiration effect of the ongoing rise in the air's CO2 content, the increase in temperature that is predicted by climate models for the year 2050, if it ever comes to pass, will likely lead to increases in winter wheat production in the northwestern part of China, not the decreases that climate alarmists routinely predict.»

Where CO2 is relevant is in explaining much of growth in crop yields — I have just done a test using a quadratic function on CO2, temperature, and rainfall which produces an amazingly accurate hindcast of wheat yields in Moree NSW 1965 - 1999 using just those 3 variables.
