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 the Problem**: Farmers are looking for ways to increase crop yield without incurring high costs or harming the environment. Traditional methods like fertilizers and pesticides are often expensive and can lead to pollution.

**Hint**: Identify the main concerns of farmers regarding yield, cost, and environmental impact.

2. **Evaluating Traditional Methods**: Traditional agricultural practices include the use of fertilizers, pesticides, and manures. While these can enhance yield, they are costly and contribute to environmental pollution, particularly water pollution.

**Hint**: Consider the pros and cons of traditional farming methods.

3. **Exploring Alternatives**: Organic agriculture is another option, which focuses on using organic manures and natural farming practices. Although it is environmentally friendly, it may not provide the high yields that farmers desire and can also be costly.

**Hint**: Assess the effectiveness of organic farming in terms of yield and cost.

4. **Introducing Genetic Engineering**: Genetic engineering offers a promising solution. By altering the genetic makeup of crops through the insertion of beneficial genes, farmers can achieve higher yields in a cost-effective manner without harming the environment. This method produces genetically modified crops that are designed for better performance.

**Hint**: Think about how genetic engineering can change the characteristics of crops for better yield.

5. **Analyzing Options**:
- **Agrochemical-based agriculture**: This involves the use of chemicals, which is not suitable due to pollution and cost.
- **Organic agriculture**: While it is environmentally friendly, it may not yield high enough returns for farmers.
- **Genetically engineered crop-based agriculture**: This is the most viable option as it allows for high yield and cost-effectiveness without environmental harm.
- **Green revolution**: This refers to historical agricultural advancements that may not specifically address the current concerns of cost and pollution.

**Hint**: Compare the options provided and determine which aligns best with the goal of maximizing yield while minimizing cost and environmental impact.

6. **Conclusion**: The best approach for farmers to achieve cost-effective maximum yield without polluting the environment is through genetically engineered crop-based agriculture.

**Final Answer**: Genetically engineered crop-based agriculture is the correct answer.
