Seedling Emergence Studies on Upland Cotton in Arizona in 1985

Abstract

Seed of 19 upland cotton varieties was planted early in the season at 3 locations to evaluate relative emergence. Variety comparisons for seedling emergence were consistent at the 3 locations. Comparison of performance of older varieties with past years showed consistent relative emergence in 7 comparisons and an apparent weak seed lot for one variety in 1985 and apparent weak seed lots for another variety in past years. Deltapine 41 has consistently been near the bottom in early season seedling emergence over years and Deltapine 61 has been below average.
