Nitrogen-efficient crops on the horizon: Can we grow more with fewer emissions?

EL BATAN, Mexico (May 17, 2017) – Through a natural, affordable alternative to farmers’ heavy use of nitrogen fertilizers, science now offers an option to boost crop productivity and dramatically reduce greenhouse gas emissions, according to the authors of a report that will appear this week in the journal Plant Science.

The new study describes certain plants that possess a trait known as biological nitrification inhibition (BNI), by which they suppress the loss of nitrogen (N) from the soil and improve the efficiency of its uptake and use by themselves and other plants.

The authors, who form part of a new BNI research consortium, propose transferring the BNI trait from those plants to critical food and feed crops, such as wheat, sorghum and Brachiaria range grasses.

“Nearly a fifth of the world’s fertilizer, for example, is deployed each year to grow wheat and the crop only uses about 30 percent of the nitrogen applied,” according to Guntur Subbarao, a researcher with Japan’s International Research Center for Agricultural Sciences (JIRCAS) and lead author of the study.

New CGIAR Research Portfolio tackles growing complexity of agricultural development challenges

MONTPELLIER, France (May 15, 2017) – CGIAR has launched a new portfolio of research programs designed to reduce by 150 million the number of people who do not have enough food to eat in developing nations. By transforming agricultural and food systems, the CGIAR Portfolio 2017-2022 is the second generation of CGIAR’s Research Programs and Platforms aimed at reducing rural poverty, improving food and nutrition security and improving natural resources and ecosystem services.

New study reveals how controlling wheat hormones can cool hot crops

By Katie Lutz/ February 2, 2017

MEXICO CITY, Mexico (CIMMYT) — Reductions of spike-ethylene, a plant-aging hormone, could increase wheat yields by 10 to 15 percent in warm locations, according to a recent study published in New Phytologist journal.

Ethylene is usually produced by plants at different developmental stages and can cause a wide range of negative effects on plant growth and development.

When hot weather hits a wheat field an increase in ethylene levels can lessen the amount of grains produced on ears or spikes by limiting the export of carbohydrates to pollen development.

Crop sensors sharpen nitrogen management for wheat in Pakistan

By Abdul Hamid, Ansaar Ahmed and Imtiaz Hussain/ February 1, 2017

ISLAMABAD (CIMMYT) – Pakistani and the International Maize and Wheat Improvement Center (CIMMYT) scientists are working with wheat farmers to test and promote precision agriculture technology that allows the farmers to save money, maintain high yields and reduce the environmentally harmful overuse of nitrogen fertilizer.

Wheat is planted on more than 9 million hectares in Pakistan each year. Of this, 85 percent is grown under irrigation in farming systems that include several crops.

Containing the menace of wheat rusts

In the 2014/15 cropping season, Ethiopia produced 4.23 million tons of wheat grain on 1.7 million hectares of land, with an increase of more than 2 million tons since 2007/8. Wheat is an incredibly important crop in Ethiopia and significantly contributes to the livelihood of smallholder farmers and urban consumers.

High returns to global wheat research

Building on more than a half-century of proven impacts, the global wheat improvement system led by CGIAR centers continues to be the chief source for wheat farmers in Africa, Asia and Latin America of critical traits such as high yields, disease resistance and enhanced nutrition and quality.

A recently-published study found that CGIAR-derived varieties – nearly all traceable to CIMMYT and ICARDA breeding programs – cover more than 100 million of 220 million hectares worldwide and bring economic benefits of as much as $3.1 billion each year. To achieve impacts in wheat agri-food systems, CIMMYT and ICARDA depend on national partnerships in over 100 countries and critical support from CGIAR Fund Donors and other contributors, whom we sincerely thank on behalf of the world’s wheat farmers and consumers.

Assessing the impact of CIMMYT on capacity development in China

A study recently published by the Center for Chinese Agricultural Policy of the Chinese Academy of Science showed that the International Maize and Wheat Improvement Center (CIMMYT) has provided an increasing number of training opportunities for Chinese scholars in the past four decades. 350 Chinese researchers had taken part in CIMMYT wheat training programs since 1970, of which 15 percent were female during 1980-1990; rising to 35 percent female during 2000-12. Since the 1990s, there was an increasing focus on young scientists.

Annual meeting in Ciudad Obregón fosters international research partnerships

By Katie Lutz
Each year, hundreds of wheat researchers from across the globe gather in Ciudad Obregón, Mexico to participate in the International Maize and Wheat Improvement Center’s (CIMMYT) Global Wheat Program (GWP) Visitor’s Week at the Campo Experimental Norman E. Borlaug (CENEB.) This year 220 guests from 31 nations attended visitor’s week during 14-18 March, ending just one week before what would have been 1970 Nobel Peace Prize laureate and former CIMMYT wheat breeder, Norman E. Borlaug’s, 102nd birthday.

The events held in Obregón help to foster a relationship between wheat researchers and facilitate partnerships worldwide. Participants are invited to attend the GWP Field Day at CENEB during the peak of the Obregón wheat growing season to learn more about CIMMYT programs and hear updates on the latest research.
