Sentences with phrase «wheat yield loss»

Not exact matches

None of the strategies tested offset the expected fall in wheat production, but the study identified directions for wheat breeding (canopy vigour and root characteristics) and management to minimise yield losses in a hotter and drier climate.

It also implies that the apparent loss of genetic diversity following the introduction of high - yielding Green Revolution wheat and rice varieties in the 1960s and 1970s, and attending the rapid adoption of superior GM crops today, is far from a new phenomenon.

A new paper from scientists at the John Innes Centre in Norwich explains why plant breeders have found it difficult to produce wheat varieties which combine high yield and good resistance to Septoria, a disease in wheat which can cut yield losses by up to 50 %.

Fusarium Head Blight (FHB) is a fungal disease that affects worldwide wheat production due to dramatic yield loss, and reduced grain quality from toxins that make harvests unsuitable for consumption.

The yield losses for potatoes, wheat and celeriac are between 18 to 19 percent and therefore somewhat higher.»

The research opens up a whole new area of exploration for scientists as they try to increase the yields of wheat and decrease losses due to excessively humid conditions.

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.

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

As extreme heat spreads across the middle of the country by the end of the century, some states in the Southeast, lower Great Plains, and Midwest risk up to a 50 % to 70 % loss in average annual crop yields (corn, soy, cotton, and wheat), absent agricultural adaptation.

Among the economic costs climate change is expected to enact on the United States over the next 25 years are: $ 35 million in annual property losses from hurricanes and other coastal storms, $ 12 billion a year as a result of heat wave - driven demand for electricity, and tens of billions of dollars from the corn and wheat industry due to a 14 percent drop in crop yields.
