Previous Year Question

A. Golden Revolution — Horticulture and Honey (2). The Golden Revolution is associated with the development of horticultural crops and honey production in India. It emphasised increasing the production and productivity of fruits, vegetables, flowers, spices, and other horticultural products. Besides honey production, beekeeping also helps improve the productivity of several crops through pollination.

B. Grey Revolution — Fertilisers (4). The Grey Revolution is associated with the production and availability of fertilisers. Fertilisers supply essential nutrients such as Nitrogen (N), Phosphorus (P), and Potassium (K) for agricultural production. Their balanced application helps maintain soil fertility and crop productivity, whereas excessive or imbalanced use can adversely affect soil and the environment.

C. Yellow Revolution — Oilseed Production (1). The Yellow Revolution is associated with increasing the production of oilseeds and edible oils. It promoted the cultivation of mustard, groundnut, soybean, sunflower, and other oilseed crops. The Technology Mission on Oilseeds, launched in 1986, played an important role in expanding oilseed production. It helped India improve its self-sufficiency in edible oils during the early 1990s.

D. Black Revolution — Petroleum Production (3). The Black Revolution is associated with the production of petroleum and petroleum products. Petroleum is an important resource for energy generation, transportation, petrochemical industries, and industrial activities. Major petroleum-producing regions in India include Assam, Gujarat, Mumbai High, and the Krishna-Godavari Basin. The Black Revolution is associated with the petroleum sector rather than any particular agricultural crop.
