Management of Micronaire Values by Defoliation Timing In Three Mid-Full Season Cultivars

The objective of this study was to manage micronaire values through different defoliation timings in three mid-full season cotton varieties; Delta Pine 1050 B2RF, Phytogen 565 WRF, and Stoneville 5458 B2RF by applying harvest aids at different open boll percentages. Since these varieties are known to receive higher micronaire values our purpose of this study was to find the optimum time to apply harvest aids in order to keep micronaire values in the premium range without sacrificing lint yield for each of the selected varieties.
