Micronaire is a measure of fibre linear density (fineness) and maturity. Factors affecting supply and partitioning of photosynthetic assimilates to fruit affect micronaire.

Dryland cotton is often grown using skipped rows because of variable summer rainfall.

Choosing the best time of sowing in a particular region can often be difficult, as it is a decision that must strike a balance between sowing too early and enduring problems associated with cold weather or sowing too

Earlier maturity in cotton would counteract increasing production costs and facilitate the expansion of cotton production into areas with shorter growing seasons.
