Improvement in Food Resources
Chapter 12 of the Class 9 NCERT Science textbook asks how a growing population can be fed sustainably. Learners study crop seasons, variety improvement, manuring, fertilisers, irrigation and cropping patterns that raise yields while protecting soil. Plant protection and scientific storage guard harvests against pests and loss. Animal husbandry completes the picture through cattle, poultry, fisheries and beekeeping, with attention to feed, shelter and disease control, so that farms deliver more milk, eggs, fish and honey without exhausting the land.
