Reference excerpt

Dr. Sanjaya Rajaram (1943 – 17 February 2021) was an Indian-born Mexican scientist and winner of the 2014 World Food Prize. He was awarded this prize for his scientific research in developing 480 wheat varieties that have been released in 51 countries. This innovation has led to an increase in world wheat production – by more than 200 million tons – building upon the successes of the Green Revolution. The Government of India awarded him India's fourth- and third-highest civilian awards Padma Shri (2001) and Padma Bhushan (2022).

Early life, education and family Sanjaya Rajaram was born in 1943 near a small farming village Raipur, District Varanasi in the state of Uttar Pradesh in northern India. His family, including his parents, an older brother and a younger sister, made a meagre living on their five-hectare farm growing wheat, rice and maize. Unlike most children in his socioeconomic position, he was encouraged to pursue an education by his parents, and graduated from secondary school as the top-ranked student in the entire Varanasi District. Rajaram went on to earn a B.Sc. in agriculture from the University of Gorakhpur, a M.Sc. in genetics and plant breeding from the Indian Agricultural Research Institute (IARI) in New Delhi and a Ph.D. in plant breeding from the University of Sydney. While at the IARI in 1964, he studied genetics and plant breeding under Prof. M.S. Swaminathan.

Career In 1969, Rajaram began working in Mexico as a wheat breeder at the International Maize and Wheat Improvement Center (CIMMYT). He was recruited by and worked alongside scientists Norman Borlaug and his deputy Canadian Glenn Anderson, in experimental wheat fields in El Batan (Texcoco), and in the Mexican cities of Toluca and Ciudad Obregon, Sonora. In 1972, he became the director of CIMMYT at the age of 29. After 33 years at CIMMYT, including seven as Director of the Global Wheat Program, Rajaram joined the International Center for Agricultural Research in the Dry Areas (ICARDA) as Director of Integrated Gene Management before formally retiring in 2008. During his distinguished career, Rajaram's work resulted in the release of more than 480 varieties of bread wheat in 51 countries, which are grown on more than 58 million hectares worldwide. Rajaram, an elected Fellow of the National Academy of Agricultural Sciences, was also the owner and director of Resource Seed Mexicana, a small private company specializing in wheat development and promotion. Rajaram died from COVID-19 on 17 February 2021, in Ciudad Obregon, Mexico.

Awards and recognition In 2022, Sanjay Rajaram received Padma Bhushan from Government of India; the award is the third-highest award that a civilian can receive.

Worked examples

Example 1 — a first encounter with Sanjaya Rajaram

Start with the simplest possible case. Write down what Sanjaya Rajaram claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sanjaya Rajaram before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sanjaya Rajaram ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sanjaya Rajaram

In research: Sanjaya Rajaram appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sanjaya Rajaram in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sanjaya Rajaram is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, 2021 deaths, 20th-century agronomists, so understanding it makes those chapters shorter.
In everyday life: Look for Sanjaya Rajaram outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
