Cotton Row Spacing Studies, Safford Agricultural Center

Abstract

A row spacing study was conducted at the Safford Agricultural Center from 1989 to 1991, evaluating the effects of 40 inch, 36 inch, 36-30 inch and 30 inch row spacing on Pima and upland cotton. The results of the study are not clear cut in favor of narrow or wide row cotton. Trends make it appear that narrow rows are more favorable for upland than Pima cotton varieties. Insufficient data is available at this point to make a firm recommendation.
