Farmer may obtain cost effective maximum yield from their fields without polluting environment by

Options

A. Argo-chemical based agriculture
B. Organic agriculture
C. Genetically engineered crop-based agriculture
D. Green revolution

Answer

To solve the question of how farmers can obtain cost-effective maximum yield from their fields without polluting the environment, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Maximum Yield**: Maximum yield refers to the highest possible crop production that can be achieved from a given area of land. The goal is to increase productivity while minimizing environmental impact.

2. **Agrochemical-Based Agriculture**: This method involves using homemade pesticides and fertilizers. Since these are made from natural ingredients, they do not introduce harmful chemicals into the environment. This approach can help in achieving high yields without pollution.

3. **Organic Culture**: Organic farming focuses on using organic manure and natural materials to enhance soil fertility and crop growth. This method avoids synthetic fertilizers and pesticides, thus protecting the environment while still aiming for high productivity.

4. **Genetically Engineered Crops**: While genetically engineered crops can lead to increased yields, they often involve gene alterations that may introduce harmful substances into the ecosystem. This can lead to environmental pollution, making this option less favorable for sustainable farming.

5. **Green Revolution**: This historical agricultural movement introduced high-yielding varieties of crops and improved agricultural practices. While it significantly increased crop production, it also relied on chemical fertilizers and pesticides, which can be detrimental to the environment.

6. **Conclusion**: To achieve maximum yield without polluting the environment, farmers should focus on agrochemical-based agriculture and organic culture. These methods promote sustainable practices that enhance crop production while protecting the ecosystem.

### Final Answer:
Farmers may obtain cost-effective maximum yield from their fields without polluting the environment by adopting agrochemical-based agriculture and organic culture.
