Look very closely at your varieties and varieties planted in your area on similar soil types to your own. Look at plant height, node of first fruiting branch, fruit retention, boll size, boll integrity, presence of diseases such as vert wilt etc., root growth and crop uniformity. This will be a very good year to sort varieties for their ability to handle stress. It is very evident that some varieties have faired much better under irrigation than dry land and some have faired better on dryland than others. This has been a great year for plant breeders and growers alike to make variety decisions.
Technology exist today to allow growers to produce cotton in reduced till systems.
I have observed tremendous difference in how cotton held up, till vs no-till, this year. Stale bed and no-till cotton that was not cultivated seemed to hold up longer than conventional till cotton on the same soil types. There are so many options to consider there is no way to address them here. Each time you can reduce a trip across a field it will allow you to either save money or work more cotton acreage for the same money. There are advantages and I feel that cotton production, on many soil types and soil resource areas, must move in that direction to remain sustainable.
