Question 51
What is the primary goal of crop improvement in agriculture?
Crop improvement aims to develop plant varieties with better yield, quality, and resilience.
This involves selective breeding, hybridisation, and modern biotechnological methods to ensure that crops provide higher productivity and nutritional value while remaining adaptable to environmental stresses.

Question 52
Which of the following is a common method of disseminating information to farmers?
Information can be disseminated to farmers using multiple channels including social media, radio, and field demonstrations.
Using all these methods collectively ensures wider reach, better understanding, and practical demonstration of farming techniques, making adoption more effective.

Question 53
Which of the following periods marked the beginning of agricultural practices by early human societies?
Agriculture began during the transition from hunter-gatherer societies to settled communities, which started in the Paleolithic Age.
This period marked the initial domestication of plants and animals, laying the foundation for food production and societal development.

Question 55
What is the primary function of the reproductive system in farm animals?
The reproductive system ensures the continuation of the species by producing gametes, facilitating fertilisation, and supporting the development of offspring.
This is essential for maintaining livestock populations and genetic improvement of farm animals.

Question 56
What does the concept of demand and supply refer to in agriculture?
Demand and supply in agriculture describe how buyers' needs and sellers' production interact to determine prices and quantities in the market.
Understanding this helps farmers and policymakers make informed production, pricing, and marketing decisions.

Question 57
What is the primary goal of genetic engineering in agriculture?
Genetic engineering introduces specific genes into plants or animals to develop desirable traits such as pest resistance, drought tolerance, or enhanced nutritional content.
This modern approach complements traditional breeding and accelerates the improvement of agricultural productivity.

Question 59
What is the term used to describe the deliberate modification of an organism's genetic material using biotechnology techniques?
Genetic engineering involves directly manipulating an organism's DNA to introduce or enhance specific traits.
This biotechnological technique allows precise changes that are not achievable through traditional breeding, enabling the development of improved crops and livestock.
