I want to know the answer to the following question:
What is the optimum amount of rainfall for cotton growth?
All the background I'm provided with is that "In general, these conditions are met within the seasonally dry tropics and subtropics in the Northern and Southern hemispheres, but a large proportion of the cotton grown today is cultivated in areas with less rainfall that obtain the water from irrigation.". Is that enough to answer the question?
Answer: no
