Norman Borlaug was given Nobel Prize in which field?

Norman Borlaug received the Nobel Peace Prize in 1970 for his work behind the Green Revolution. Working on high-yielding, disease-resistant dwarf wheat in Mexico and later in India and Pakistan, he helped avert mass famine and expanded food security for millions. The committee recognised that food security is a precondition for lasting peace, which is why a plant scientist received a Peace prize.

• Agriculture: Nobel prizes have no agriculture category. Agricultural science is honoured only indirectly, through other categories.
• Economics: The Economic Sciences prize is the Sveriges Riksbank Memorial Prize, not one of the original Nobel categories, and Borlaug did not receive it.
• Medicine: The Physiology or Medicine prize rewards biomedical discoveries. Borlaug's work was on crop breeding, not human health.

Mains angle: the Green Revolution's yield gains came with costs in groundwater depletion and regional imbalance in Punjab and Haryana, a point worth raising in GS-III answers on food security and sustainable agriculture.

Trap: Aspirants who associate Borlaug with agriculture often mark A, forgetting that Nobel prizes have no agriculture category.
