Important exam questions with answers
Why is there a need for improvement in food resources in India?
India has a large and growing population but limited land for farming, so we must increase food production from the same land to feed more people. (2 points: population growth and limited farming land)
What was the Green Revolution and how did it help increase food production?
The Green Revolution was a movement that used high-yielding crop varieties, better irrigation, fertilizers, and pesticides to increase food grain production in India. (2 points: improved seeds and farming techniques)
Explain the concept of sustainable agriculture.
Sustainable agriculture means increasing food production without harming the environment or disturbing ecological balance, ensuring resources are preserved for future generations. (2 points: environmental protection and future resource use)
FAQ
What are the main sources of our food?
Our food mainly comes from agriculture (growing crops) and animal husbandry (rearing animals). You can listen to the full chapter on Harshali Academy for detailed explanations.
How do mixed farming and intercropping help farmers?
Mixed farming combines crop growing and animal rearing to save costs and improve soil fertility, while intercropping grows multiple crops together to reduce risk and use nutrients better. Harshali Academy’s audio lessons explain these methods clearly.
Why is sustainable agriculture important?
Sustainable agriculture protects soil, water, and environment while increasing food production, ensuring that future generations can also benefit. Harshali Academy covers this topic in detail to help students understand its significance.
How did the White Revolution impact India?
The White Revolution increased milk production through improved cattle breeds, veterinary care, and organized dairy systems like Amul, boosting dairy farming in India. Harshali Academy’s lessons provide more insights on this.
What are some scientific management practices used by farmers?
Farmers use improved seeds, proper irrigation, fertilizers, crop protection, and modern machinery to increase yields. Harshali Academy explains these practices with examples for better understanding.
