1. Abstract
A three-year field study is requested for the Shafter Research and Extension Center to evaluate the utility of modifications in specific management practices (planting date, irrigation rate and cutoff date management, and harvest aid timing and practices) on the development of and level of seed coat fragment problems (measured by several methods). These field evaluations would be done in several varieties previously identified (in SJV Cotton Board tests) as differing (low, moderate, high) in tendency to produce seed coat fragments as measured by several methods. The evaluations would focus on determining if a specific mix of management practices could be identified that would increase the consistency in expression of seed coat fragment problems. This could serve to both identify production management practices to avoid in years or with varieties more prone to development of seed coat fragment problems as well a…
