Agricultural Revolutions in India
What are the two major 'Revolutions' in India that significantly increased food and milk production respectively?
What are the two major 'Revolutions' in India that significantly increased food and milk production respectively?
Green Revolution: A massive agricultural programme introduced to significantly increase food-grain production by using modern technology, improved high-yielding variety (HYV) seeds, and proper irrigation.
White Revolution: A national programme designed to massively increase the production, availability, and efficient use of milk, making India self-sufficient in dairy.

Stages of Crop Yield Improvement
What are the three major scientific stages involved in improving overall agricultural crop yields?
What are the three major scientific stages involved in improving overall agricultural crop yields?
1. Crop Variety Improvement: Selecting the best, highest-yielding, and most disease-resistant seeds for planting.
2. Crop Production Management: Nurturing the crop plants via proper nutrient management, irrigation, and optimal cropping patterns.
3. Crop Protection Management: Protecting the growing and harvested crops from weeds, pests, diseases, and storage losses.

Food Crop Nutritional Profiles
How are different crops scientifically categorized based on the primary macronutrients they provide?
How are different crops scientifically categorized based on the primary macronutrients they provide?
Cereals (Wheat, Rice, Maize, Millets): Major sources of Carbohydrates for energy.
Pulses (Gram, Pea, Lentils): Primary sources of plant-based Proteins.
Oilseeds (Soyabean, Groundnut, Mustard, Sunflower): Necessary sources of dietary Fats.
Vegetables, Spices & Fruits: Provide an extensive range of Vitamins and Minerals.
