Revolutionizing Food Resources
Revolutionizing Food Resources
1. A period of rapid increase in
agricultural production in the mid-20th
century.
2. Involved in the use of high-yielding
varieties, fertilizers, and irrigation.
3. Improved global food security and
reduced poverty.
1. A movement to increase milk
production in India during the 1970s.
2. Involved in improved dairy farming
practices and cooperative marketing.
3. Resulted in India becoming one of
the largest milk producers globally.

Successful Crop Production
Understand growth and development
of crops.
Factors: nutrients, climate, water.
Focus on Kharif (June-October) and
Rabi (November-April) seasons.
Crop Variety Improvement
Through hybridization or gene
introduction.
Hybridization involves crossing
genetically dissimilar plants.
Gene introduction results in genetically
modified crops.
Enhancing Crop Yields
