Concept

In agriculture General-Knowledge questions, abbreviation items like HYV test recall of Green Revolution-era terminology. HYV stands for High Yielding Variety - crop seed strains specially bred (through selective breeding/hybridisation) to produce substantially more grain per hectare than traditional (desi) varieties, when grown with the accompanying package of assured irrigation, chemical fertilisers and pesticides.

Application

Decoding the letters in the abbreviation for this item - H = High, Y = Yielding, V = Variety - gives 'High Yielding Variety', which is exactly the term introduced during India's Green Revolution (1960s onward) to describe improved wheat and rice seed strains (e.g. the varieties associated with Norman Borlaug's research) that raised national foodgrain output.

Contrast

Each distractor borrows one of the letters but pairs it with a term from an unrelated field:

• Horticulture Yield Variety - 'horticulture' is the branch of agriculture concerned with fruits, vegetables, flowers and ornamental plants; this combination is not a recognised agricultural terminology.

• Honey Yeast Variety - 'honey' belongs to apiculture (bee-keeping) and 'yeast' is a fermentation micro-organism used in baking/brewing; neither relates to crop seed classification.

• Hemp Yarn Variety - 'hemp' is a fibre crop and 'yarn' is spun thread used in textile manufacture; this describes a textile-industry concept, not a seed-technology term.

Result: The full form of HYV in agriculture is High Yielding Variety.
