- Q1 of 6Easy
Crop yield can be improved by:
Show answerHide answer
Answer: Using high-yielding varieties
Explanation: High-yielding varieties (HYV) are bred for greater output, disease resistance and better response to fertilisers, unlike avoiding fertilisers or sowing at random, which cut yield.
- Q2 of 6Easy
Cattle reared for milk are called:
Show answerHide answer
Answer: Milch animals
Explanation: Milch animals such as Sahiwal and Jersey are bred and reared specifically for high milk output, unlike draught cattle, which are kept for farm labour like ploughing.
- Q3 of 6Medium
Nitrogen is fixed in soil naturally by:
Show answerHide answer
Answer: Legumes (with rhizobium bacteria)
Explanation: In root nodules of legumes, symbiotic Rhizobium bacteria convert atmospheric nitrogen into usable nitrates, which is why growing legumes naturally enriches soil nitrogen, unlike cereals like cotton or sugarcane.
- Q4 of 6Medium
Apiculture is the keeping of:
Show answerHide answer
Answer: Bees
Explanation: Apiculture specifically means keeping honey bees for honey and wax, while sericulture (silkworms), pisciculture (fish) and poultry (birds) are separate, unrelated practices.
- Q5 of 6Hard
Growing two or more crops simultaneously on the same piece of land is called:
Show answerHide answer
Answer: Mixed cropping
Explanation: Mixed cropping grows two or more crops together on the same land without a row pattern, cutting the risk of total failure, unlike mono-cropping (one crop) or crop rotation (crops in succession).
- Q6 of 6Hard
Pisciculture refers to:
Show answerHide answer
Answer: Fish farming
Explanation: Pisciculture is the scientific rearing and breeding of fish, such as rohu, catla and mrigal in Indian ponds, distinct from poultry, pig or bee farming.
Improvement in Food Resources notes: key concepts (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.
