Explanation: Sugar mills are industrial facilities that process sugarcane into sugar. The concentration of sugar mills in a particular state is influenced by several factors, including the availability of sugarcane, climatic conditions, and agricultural practices. In India, the states of Uttar Pradesh and Bihar are known for their significant sugarcane production, which supports a high concentration of sugar mills.
Uttar Pradesh and Bihar are located in the Gangetic plains, which have fertile soil and a climate that is conducive to sugarcane cultivation. The region receives adequate rainfall and has a long growing season, which is ideal for sugarcane. Additionally, the agricultural practices in these states are well-suited for sugarcane cultivation, making them the leading states in India for sugar production.
In contrast, other states like Punjab and Haryana are more known for their wheat and rice production. The climatic conditions and agricultural focus in these states do not support a high concentration of sugar mills. Similarly, while Maharashtra does have a significant number of sugar mills, Gujarat is not as prominent in sugar production. West Bengal and Orissa are not major producers of sugarcane, with their agricultural focus being more on other crops such as rice and jute.
Therefore, the correct answer is that sixty percent of sugar mills are concentrated in Uttar Pradesh and Bihar, due to their favorable climatic conditions, fertile soil, and agricultural practices that support sugarcane cultivation and sugar production. Understanding the geographical and agricultural factors that influence the concentration of sugar mills is crucial for comprehending the distribution of industrial activities in India.
