CGIAR is the only worldwide partnership addressing agricultural research for development, whose work contributes to the global effort to tackle poverty, hunger and major nutrition imbalances, and environmental degradation.
It is carried out by 15 Centers, that are members of the CGIAR Consortium, in close collaboration with hundreds of partners, including national and regional research institutes, civil society organizations, academia, development organizations and the private sector.
The 15 Research Centers generate and disseminate knowledge, technologies, and policies for agricultural development through the CGIAR Research Programs. The CGIAR Fund provides reliable and predictable multi-year funding to enable research planning over the long term, resource allocation based on agreed priorities, and the timely and predictable disbursement of funds. The multi-donor trust fund finances research carried out by the Centers through the CGIAR Research Programs.
We have almost 10,000 scientists and staff in 96 countries, unparalleled research infrastructure and dynamic networks across the globe. Our collections of genetic resources are the most comprehensive in the world.
What we do
We collaborate with research and development partners to solve development problems. To fulfill our mission we:
- Identify significant global development problems that science can help solve
- Collect and organize knowledge related to these development problems
- Develop research programs to fill the knowledge gaps to solve these development problems
- Catalyze and lead putting research into practice, and policies and institutions into place, to solve these development problems
- Lead monitoring and evaluation, share the lessons we learn and best practices we discover;
- Conserve, evaluate and share genetic diversity
- Strengthen skills and knowledge in agricultural research for development around the world
Making a difference
We act in the interests of the world’s poorest and most vulnerable. Our track record spans four decades of research.
Our research accounted for US$673 million or just over 10 percent of the US$5.1 billion spent on agricultural research for development in 2010. The economic benefits run to billions of dollars. In Asia, the overall benefits of CGIAR research are estimated at US$10.8 billion a year for rice, US$2.5 billion for wheat and US$0.8 billion for maize.
It has often been cited that one dollar invested in CGIAR research results in about nine dollars in increased productivity in developing countries.
Sweeping reforms for the 21st century
Political, financial, technological and environmental changes reverberating around the globe mean that there are many opportunities to rejuvenate the shaky global food system. Developments in agricultural and environmental science, progress in government policies, and advances in our understanding of gender dynamics and nutrition open new avenues for producing more food and for making entrenched hunger and poverty history.
The sweeping reforms that brought in the CGIAR Consortium in 2010 mean we are primed to take advantage of these opportunities. We are eagerly tackling the ever more complex challenges in agricultural development. We are convinced that the science we do can make even more of a difference. To fulfill our goals we aim to secure US$1 billion in annual investments to fund the current CGIAR Research Programs.
CGIAR has embraced a new approach that brings together its strengths around the world and spurs new thinking about agricultural research for development, including innovative ways to pursue scientific work and the funding it requires. CGIAR is bringing donors together for better results and enabling scientists to focus more on the research through which they develop and deliver big ideas for big impact. As a result, CGIAR is more efficient and effective, and better positioned than ever before to meet the development challenges of the 21st century.
We are no longer the ‘Consultative Group on International Agricultural Research’. In 2008 we underwent a major transformation, to reflect this and yet retain our roots we are now known simply as CGIAR.

Displaying 12486 - 12490 of 12598Suelos y nutrición de plantas
Efforts to develop cassava technology for the vast areas of acid infertile soils were continued Large-scale germplasm screening in the field was begun in Carimagua for tolerance to low levels of P and acidity and in Quilichao, for tolerance to low levels of P. Various fertilizer trials were used to determine: (a) nutrient absorption and distribution within the plant during a 12-mo.
Nutritional disorders
Different nutritional deficiencies or toxicities may limit bean development and yield. N and P deficiencies are the most frequent, although deficiency of minor elements and Al/Mn toxicity can reduce yields considerably. Nutritional problems are usually diagnosed by soil and plant tissue analyses and the observation of symptoms produced by nutritional disorders. Optimum pH for bean production varies between 6.5-7.5; within these limits, the majority of the plant nutrients have their max availability. Color illustrations are given of the symptoms of plant deficiencies and toxicities.
CIAT/IFDC phosphorus project
Se detallan evaluaciones de campo e invernadero en las que se examinaron: el efecto de diferentes rocas fosforicas (RF), la eficacia de la aplicacion de P, el tamano de los granulos y las relaciones RF: Superfosfato triple, asi como los efectos de las mezclas cogranuladas de RF con superfosfato triple y superfosfato simple, y la RF parcialmente acidulada, en varias especies, incluyendo Brachiaria decumbens, Zea mays y Panicum maximum.

White mold
White mold, caused by the fungus Sclerotinia (Whetzelinia) sclerotiorum, is distributed worldwide and has more than 300 hosts. It infects flowers, cotyledons, seeds, leaves or injured plant tissue. The disease can be controlled by crop rotation, flooding, reduced seeding rates, application of chemical products in the middle of the flowering period, modifying plant architecture and the use of resistant var. Many soil microorganisms are associated with sclerotia and may cause them to degrade or fan to germinate. The symptoms and damage caused by the disease are illustrated in color.
