Abstract
Abstract Many producers are using foliar fertilizers on seedling cotton (Gossypium hirsutum L.) with the intent of promoting early vigor and increasing yields. However, the hypothesis that foliar feeding young cotton increases seedling vigor and yield has not been rigorously tested. We conducted 5 studies during 1990 to 1992 to investigate the value of one, two or three foliar applications of 12–48–8 fertilizer to seedling cotton. Two studies also included foliar‐applied urea. Plant height and whole‐plant phosphorous (P) and nitrogen (N) were determined two weeks after each application in two studies. Yield and P and N concentrations were not influenced by foliar fertilizers in any study. Seedling height was not influenced by applications of 12–48–8. A slight early‐season height advantage was observed with foliar‐applied urea at one location. Our results suggest that application of foliar N and P fertilizers to seedling cotton has little agronomic value.
