Which of the following objective is not associated with application of agrobiotechnology

Options

A. Enhancement of nutritional quality
B. Development of resistance against abiotic stresses
C. Increased efficiency of mineral usage by plants
D. Development of humulin like hormone

Answer

To determine which of the following objectives is not associated with the application of agrobiotechnology, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Agrobiotechnology**:
- Agrobiotechnology involves the use of scientific techniques and tools to modify plants for various purposes, such as improving crop yield, resistance to pests, and nutritional quality.

2. **Evaluating Each Option**:
- **Option 1: Enhancement of Nutritional Quality**:
- This is an application of agrobiotechnology. Techniques like recombinant DNA technology can be used to introduce beneficial traits, such as increased antioxidants or dietary fibers in crops.

- **Option 2: Development of Resistance to Abiotic Stresses**:
- This is also an application of agrobiotechnology. For example, genetically modified crops like BT cotton are developed to withstand various environmental stresses and pests.

- **Option 3: Increased Efficiency of Mineral Usage by Plants**:
- This is another application of agrobiotechnology. Techniques are employed to enhance the root systems of plants, allowing them to absorb minerals more effectively.

- **Option 4: Development of Humulin-like Hormone**:
- This option refers to the production of a man-made insulin (humulin) using E. coli, which is not related to plant biotechnology. This process involves microbial biotechnology rather than agrobiotechnology.

3. **Conclusion**:
- After evaluating all options, it is clear that the **development of humulin-like hormone** is not associated with agrobiotechnology. Therefore, the correct answer is **Option 4**.
