Key concepts: Improvement in Food Resources (Old Syllabus) (Class 9 Science)
This chapter covers how crop and animal yields are improved — through variety improvement, crop management, mixed and inter-cropping, and animal husbandry.
- Need for higher yield
- A growing population needs more food, achieved by improving crops and livestock without harming sustainability.
- Crop variety improvement
- Hybridisation (crossing varieties) and selection for traits like higher yield, disease resistance and quality.
- Nutrient and crop management
- Macro- and micro-nutrients come from manure and fertilisers; manure improves soil structure, fertilisers give specific nutrients but can harm soil if overused.
- Cropping patterns
- Mixed cropping (two crops together), inter-cropping (set rows) and crop rotation reduce risk and maintain soil fertility.
- Animal husbandry
- Scientific rearing of cattle, poultry and fish for milk, eggs, meat — covering breeding, feeding, shelter and disease control.
- Storage of grains
- Losses are caused by biotic factors (insects, rodents, fungi) and abiotic factors (moisture, temperature); proper drying and storage reduce them.
💡 Exam tips for Improvement in Food Resources (Old Syllabus)
- Distinguish mixed cropping (mixed together) from inter-cropping (definite row pattern) — a frequent exam point.
- Manure improves soil texture and adds organic matter; fertilisers supply specific nutrients but need careful use.
Sample questions
Crop yield can be improved by:
HYV seeds are bred for better yield, disease resistance, etc.
Nitrogen is fixed in soil naturally by:
Root nodules of legumes host Rhizobium bacteria that fix atmospheric N.
Growing two or more crops simultaneously on the same piece of land is called:
Mixed cropping reduces risk of crop failure and uses nutrients efficiently.
