Based on the options provided, the innovations in farming techniques that led to great productivity are:

- Pest control
- Irrigation
- Inorganic fertilizers
- Crop rotation

To determine the innovations in farming techniques that led to great productivity, we need to analyze each option and identify the ones that are relevant to agriculture.

1. Self-winding watch: This innovation is not related to farming techniques or productivity.

2. Pest control: Pest control methods such as using pesticides and integrated pest management systems have significantly improved crop productivity by reducing damage caused by pests. This option is relevant.

3. Irrigation: The introduction of efficient irrigation methods, like drip irrigation or sprinkler systems, has allowed farmers to provide consistent water supply to their crops, resulting in increased productivity. This option is relevant.

4. Inorganic fertilizers: The use of chemical or inorganic fertilizers has been one of the major innovations in farming. These fertilizers provide essential nutrients to plants, promoting healthier growth and higher yields. This option is relevant.

5. Cotton mill: A cotton mill is not directly related to farming techniques or agricultural productivity. It is an industrial facility involved in processing cotton into textiles.

6. Uses for grain products: While this option doesn't specify any particular innovation, finding new uses for grain products can drive market demand and ultimately increase productivity for farmers growing those crops. Although the option is general, it is relevant.

7. Crop rotation: Crop rotation involves systematically changing the crops planted in a certain area over time, which helps prevent soil depletion, control pests and diseases, and improve overall productivity. This option is relevant.

Based on the above analysis, the relevant innovations in farming techniques that led to great productivity are: pest control, irrigation, inorganic fertilizers, and crop rotation.
