Reference excerpt

Rajagopalan Krishnamurthy (born 27 March 1928) is an Indian cotton researcher. He is a prolific Indian plant breeder who introduced a myriad of cotton varieties for commercial cultivation. He served in the Department of Agriculture of Tamil Nadu for one decade and almost 28 years in Indian Council of Agricultural Research (ICAR). He has released as many as 6 varieties from G. Hirsutum, two from G. Barbadense and three hybrids during his tenure in ICAR Service. All of them are prominent and accepted by the farmers as well as the textile mills at Tamil Nadu and elsewhere. He completed B. Sc.(Agri.) and M. Sc. (Agri.) in plant breeding and genetics from Tamil Nadu Agricultural University, Coimbatore. He is also the Research Director - Cotton of Rasi Seeds Pvt. Ltd.

Famous varieties

Suvin cotton Suvin is the Jewel in the Indian cotton crown. The king of cotton and India's pride. “Suvin” variety was released in 1979 by cross breeding Sujatha (Indian cotton variety) with St. Vincent (Sea-Island cotton variety). Suvin is the finest cotton being produced in India and has no parallel and alternative in the world today. It is the only commercially available fiber in the world with spinnability up to 240s count. The highest production of Suvin was 36,000 bales (170 kg), achieved in the year 1989-90. However, the production of Suvin has depleted steadily over the years and currently stands at 300 MT i.e. around 1250 bales.

Other varieties Other varieties include b

Hybrids developed in the private sector Responsible for developing and releasing 43 cotton hybrids. Under the Bt cotton Programme, involving Bollgard-1 and Bolgard-2 genes, 14 Bt cotton hybrids have been released for the North, Central and South zones of India & Bt hybrids have been released through other cotton seed companies in the country. 3. 20 Bt cotton hybrids are at advanced stages of testing, while 6 Bt hybrids are awaiting approval for commercial release. During 2007, 9 Bt hybrids were proposed for RGGM trial all over the country.

(1988), Rao Bahaddur Ramanath Iyer Award, 1990–91, by ISCI, Mumbai. For outstanding contribution in the field of Cotton Breeding and Genetics. (1992) ABLE Award, for excellence in Agriculture Sciences (2007). Honorary Fellowship to Sri. R. Krishnamourthy, by ISCI on 16 June 2007. Sri. Krishnamourthy has been continuously involved in Cotton research for more than 5 decades and whose Research output has been commercialized extensively. Cotton hybrids developed by him have benefited the nearly 1 to 1.5 million farming community, during the Non-Bt cotton days and 1.5 to 2 million farmers during the introduction of Biotech Cottons, in India. The cottons have impressive yield advantage compared to other hybrids and accomplished a peak coverage of 21,200 km2 during 1997–98 and 2,760,000 acres (11,200 km2) during 2006—07. The sizable coverage led to an additional cotton production of 3,000,000 bales in the country, which accounts for approximately 30% of cotton production. Out of the 62 Bt cotton hybrids approved by the Regulatory Authority for Commercialization in India, 21 Bt cotton hybrids have been developed by Sri. Krishnamourthy, under the Rasi Seeds banner. Constituting 33.9% of the total Bt cotton hybrids released for commercialization, they occupy 29% of the hybrid cotton area in India. Rasi seeds have bagged, “DSIR National Award for R&D efforts in Industry (2005) in the commercialization of Technologies Acquired from others.” ISCI Awards, published on June 16, 2007, by the Journal of ISCI, Matunga, Mumbai – 400 019.

Publications He has published over 35 research papers in journals of high repute.

Worked examples

Example 1 — a first encounter with Rajagopalan Krishnamurthy

Start with the simplest possible case. Write down what Rajagopalan Krishnamurthy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Rajagopalan Krishnamurthy 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 Rajagopalan Krishnamurthy 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 Rajagopalan Krishnamurthy

In research: Rajagopalan Krishnamurthy appears in astronomy 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 Rajagopalan Krishnamurthy 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: Rajagopalan Krishnamurthy is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, Living people, Tamil Nadu Agricultural University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Rajagopalan Krishnamurthy 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.
