Reference excerpt

Madappa Mahadevappa (4 August 1937 – 6 March 2021), popularly known as Rice Mahadevappa was an Indian agricultural scientist and plant breeder, renowned for developing high yielding hybrid varieties of rice. He served for more than 55 years and had a glowing career. He served as the Vice-chancellor of University of Agricultural Sciences, Dharwad for two terms (1994 - 2000) and his selfless hard work along with broad vision lead to the award of ICAR's SARDAR PATEL OUTSTANDING INSTITUTION award in the year 2000 to UAS, Dharwad. He served as chairman of Agricultural Scientists Recruitment Board (2002 - 2003) under Indian Council of Agricultural Research of which he was a member of governing council. As chairman of ASRB, he introduced radical changes to create transparency in recruitment and expedited the process of promotions. This enhanced the talent pool at ICAR system to further contribute to the cause of the agriculture and farming community. He was the recipient of Padma Bhushan, India's third highest civilian honour, Padma Shri and various other accolades.

Contributions Mahadevappa, an elected fellow of the National Academy of Agricultural Sciences, contributed extensively to the Indian agrarian community through various innovative applications and research initiatives including development of over nine varieties of high yielding hybrid rice varieties. While being a pioneer in hybrid rice farming in the country, he was also credited for his Integrated Parthenium Weed Management, a scientific and efficient weed management technique against the invasive Parthenium. After retirement, he has been serving as Director of Rural Dev in JSS Mahavidyapeetha, Mysore - a reputed NGO with 340 institutions in four countries. He implemented the novel ‘seed village’ concept to uplift the socio-economic status of BPL farmers (7633 families benefited in ~500 villages of 28 districts) by reducing their dependency on external agencies and by providing sustained employment with the financial support of Rural Development Ministries. Implementation included establishment of i) Seed processing and storage units ii) 50 horticulture and forestry nurseries iii) 20 commercial silkworm chawki Rearing Centres iv) 40 shade net houses for producing vegetables and v) 300 value addition units. After retirement till his last breath, he was serving as Director of Rural Dev in JSS Mahavidyapeetha, Mysore - a reputed NGO with 340 institutions in four countries. He implemented the novel ‘seed village’ concept to uplift the socio-economic status of Below Poverty Line (BPL) farmers (7633 families benefited in ~500 villages of 28 districts) by reducing their dependency on external agencies and by providing sustained employment with the financial support of Rural Development Ministries. Implementation included establishment of i) Seed processing and storage units ii) 50 horticulture and forestry nurseries iii) 20 commercial silkworm chawki Rearing Centres iv) 40 shade net houses for producing vegetables and v) 300 value addition units. He is the Founder and Chief Editor of popular Kannada quarterly “Krishi Kayaka” which is widely subscribed as a useful resource of information for farmers, students and extension workers. Mahadevappa was a recipient of the Padma Bhushan and Padma Shri.

Death Mahadevappa died on 6 March 2021, due to age related ailments, in Mysore.

Worked examples

Example 1 — a first encounter with M. Mahadevappa

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

In research: M. Mahadevappa appears in engineering 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 M. Mahadevappa 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: M. Mahadevappa is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1937 births, 2021 deaths, 20th-century Indian botanists, so understanding it makes those chapters shorter.
In everyday life: Look for M. Mahadevappa 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.
