What is the five crops grown in large scale farming?

It's impossible to give you a definitive "top five" because the most widely grown crops vary depending on factors like:

* Location: Different regions have different climates and soil conditions, which favor certain crops.

* Year: Crop production changes due to market demand, weather patterns, and other factors.

* Definition of "large scale": Are we talking about global production, national production, or a specific region?

However, some of the most common large-scale crops globally include:

Grains:

* Corn (Maize): Used for feed, food, and biofuel.

* Wheat: A major source of carbohydrates worldwide.

* Rice: A staple food for billions of people, especially in Asia.

Other:

* Soybeans: Used for oil, protein, and animal feed.

* Sugarcane: A major source of sugar.

Other notable large-scale crops:

* Potatoes

* Cotton

* Palm Oil

* Coffee

* Bananas
