Try it in the interactive lab🔊 Audio

Topic: Biology · Class 9 · Improvement in food resources: crop protection and storage

Aim: Bring in the harvest with less than 10% loss and without harming the soil.

Daily: India loses a significant share of its grain after harvest, to moisture, insects and rodents. Storing well is as important as growing well.

Question: Grain is stored damp in open sacks. The biggest cause of loss will be…

Exp: Moisture invites fungal growth, and open sacks invite pests.

Question: Crossing two varieties to combine desirable traits is called…

Exp: It is central to crop improvement.

Question: A drawback of heavy pesticide use is…

Exp: IPM keeps chemicals as a last resort.

Question: Growing two crops in the same field in a set pattern is…

Exp: It reduces pest spread and uses nutrients better.

Question: Before storing grain, it must be…

Exp: Moisture causes fungal growth and spoilage.
