Assertion: There is a need for suitable practices in agriculture.
Reason: The population of the country is still growing.

Explanation:

Introduction:
Agriculture plays a crucial role in sustaining human life by providing food and raw materials for various industries. With the continuous increase in the global population, there is a need for suitable practices in agriculture to ensure food security, sustainable development, and environmental preservation.

Population Growth:
The reason provided for the need for suitable practices in agriculture is the growing population. Let's explore this reason in detail.

1. Increasing Demand for Food:
As the population grows, the demand for food also increases. The global population is expected to reach 9.7 billion by 2050, according to the United Nations' projections. This means that there will be more mouths to feed, and agriculture needs to produce enough food to meet this demand.

2. Limited Arable Land:
The available arable land for agriculture is limited and cannot be expanded indefinitely. Urbanization, industrialization, and environmental degradation have led to the shrinking of arable land. Therefore, it becomes essential to adopt suitable practices in agriculture to maximize the productivity of existing land.

3. Ensuring Food Security:
Food security is a fundamental aspect of a growing population. Suitable agricultural practices such as crop rotation, integrated pest management, precision farming, and efficient irrigation techniques can help increase crop yields and minimize post-harvest losses. These practices ensure a steady food supply and reduce the risk of food shortages.

4. Environmental Sustainability:
Unsustainable agricultural practices can have detrimental effects on the environment. Excessive use of chemical fertilizers and pesticides, deforestation, and water pollution are some of the challenges faced by modern agriculture. By adopting suitable practices like organic farming, agroforestry, and water conservation, we can minimize the negative impact on the environment.

5. Economic Development:
Agriculture is not only important for feeding the population but also for economic development. Suitable practices can enhance agricultural productivity, increase farmer income, and promote rural development. This, in turn, contributes to overall economic growth and stability.

Conclusion:
The assertion that there is a need for suitable practices in agriculture is supported by the reason that the population of the country is still growing. By adopting suitable practices, we can ensure food security, environmental sustainability, and economic development in the face of increasing population pressure. It is crucial to prioritize research, innovation, and education in the field of agriculture to meet the challenges of feeding a growing population while preserving our planet's resources.
